Add an offline bundle and cache for every host-side download, so a run can resolve Helm, Kubescape, the Kyverno CLI and policies, the Litmus operator and fault manifests, and the Kyverno policies without network access.
Add Offline and Airgap helpers, airgap_prepare/airgap_status, recursive CNF manifest scanning, and cached image collection.
Fail missing downloads with the URL and bundle path, and skip registry-only checks with a reason instead of waiting on a timeout.
Patch cached Litmus manifests to use local images and include the operator's CHAOS_RUNNER_IMAGE in the collected image list.
Add the airgap workflow: GitHub-hosted runner, kind cluster, blocked egress, preloaded images, and an offline cert run.
Document the bundle and the two offline environment variables, and fix the Renovate image regex for the ClusterTools constant.
Verified with crystal build, the airgap/offline specs, and a local airgap_prepare smoke test.
Summary by CodeRabbit
New Features
Added tools to prepare and check an air-gap bundle containing required images, downloads, and policies.
Added offline mode for setup and certification, using local bundle contents and adjusting image pulls for offline installation.
Offline runs skip checks that require registry access, including image-size measurements, SBOM inspection, and certain rollout or chart checks.
Missing bundle artifacts now produce an error identifying the unavailable item and how to prepare or locate the bundle.
Documentation
Documented bundle preparation, offline setup and testing, status checks, and configuration options.
Tests
Added coverage for bundle contents, cached downloads, and offline image handling.
This change adds offline artifact caching and bundle preparation, adjusts selected workload checks for offline mode, documents the air-gap workflow, and adds a GitHub Actions workflow that runs certification with outbound network access blocked.
Offline downloads resolve from a URL-specific cache and fail when an artifact is missing. Litmus manifests and templates use local image pull policies offline. Kyverno policies load from the bundle. Specs cover cache behavior and local manifest handling.
Bundle preparation and status src/tasks/airgap.cr, spec/tasks/airgap_spec.cr, src/tasks/utils/cli_help.cr, docs/USAGE.md
airgap_prepare caches host artifacts and Kyverno policies, collects and deduplicates image references, and writes an image list. airgap_status reports bundle contents. CLI help, usage documentation, and specs cover these operations.
Selected registry-dependent checks skip in offline mode. The cluster-tools image is defined as a constant, and the Renovate Docker manager recognizes assigned image values.
Workflow setup and image loading .github/workflows/airgap.yml
The workflow prepares the image list, creates a three-node kind cluster, and loads the bundle images.
Network isolation and certification .github/workflows/airgap.yml
The workflow blocks outbound connections from the kind network and pod CIDR, checks pod connectivity, runs setup, installation, and offline certification, uploads results, and attempts cleanup.
lfn-cnti/testsuite#2845: Both changes affect the cluster-tools image reference; this change centralizes it and includes image collection for the offline bundle.
lfn-cnti/testsuite#2846: Both changes affect Litmus fault artifact retrieval; this change discovers and caches fault manifests for offline installation.
lfn-cnti/testsuite#2850: The Kyverno URL changed by that PR is cached as a required host artifact here.

Merge Risk: Low · up to 1f85c
A configured mirror whose URL contains “github.com” can receive the GitHub token during bundle preparation. Match the destination host before sending credentials; the remaining risk is bounded.
Security architecture risk: Low · up to 1f85c
The new preparation path can send a GitHub token to an unintended artifact server. Exposure requires a token and influence over a configured download destination or redirect. Trusted defaults and read-only CI permissions limit the demonstrated scope, but offline execution does not protect the earlier connected preparation phase.
Retained concerns
Low · security · observed: The new preparation path binds GitHub credential authority to URL text rather than the destination authority. A configurable Litmus mirror whose hostname, path, or query contains a matching substring receives GITHUB_TOKEN; the downloader also carries that header to redirect destinations. Trusting a mirror to supply manifests does not inherently authorize it to receive GitHub credentials.
Security review details
Security Blast Radius
inferred — The independently exposed authority is the GitHub token available to an affected preparation invocation. The supplied workflow limits that authority to read-only repository contents. Locally supplied tokens may have different permissions, which were not established; cluster-wide or cross-tenant compromise is not demonstrated by this path.
Security Findings and Attack Paths
inferred — A party influencing the configured mirror can arrange a URL such as https://github.com.attacker.example that passes substring matching. An uncached preparation request then sends the bearer token to that server. Header-preserving redirects provide another route when a credential-bearing request is redirected to an unintended destination. A token and destination influence are prerequisites; no attack against the default workflow configuration was demonstrated.
Trust Boundaries and Controls
observed — The default fault source is raw.githubusercontent.com, and no authorization header is generated without a nonempty token. Runtime Litmus installation requires an HTTPS mirror, but preparation constructs and downloads fault URLs without applying that check. Neither the default nor the runtime scheme check binds preparation credentials to an intended recipient.
Resilience and Maintainability Implications
observed — Individual downloads use PID-suffixed temporary files, check advertised length, and publish only after completion; cleanup handles ordinary failures. Policy replacement deletes the previous directory before copying, and images.txt is written directly, so the bundle as a whole is not transactional. Preparation reports recorded failures with a nonzero exit, and the supplied CI caller stops on that exit. No security bypass from partial bundle publication was established.
Hardening Proposals
proposed — Bind authentication to parsed HTTPS authorities explicitly authorized to receive the token, and re-evaluate or remove sensitive headers on cross-origin redirects. Keep mirror content trust separate from credential-recipient trust.

<excerpt>citeturn0search4 [wordlim: 200] Crawled: last week; In addition to runner environment variables, GitHub Actions allows you to set and read `env` key values using contexts. ... For example, an `if` conditional, which determines whether a job or step is sent to the runner, is always processed by GitHub Actions. ... We access this value from the `if` conditional statement by using the `env` context.
## Using contexts to access variable values
Contexts are a way to access information about workflow runs, variables, runner environments, jobs, and steps. For more information, see Contexts reference. There are many other contexts that you can use for a variety of purposes in your workflows. For details of where you can use specific contexts within a workflow, see Contexts reference.
You can access environment variable values using the `env` context and configuration variable values using the `vars` context.
### Using the `env` context to access environment variable values
In addition to runner environment variables, GitHub Actions allows you to set and read `env` key values using contexts. Environment variables and contexts are intended for use at different points in the workflow.
The `run` steps in a workflow, or in a referenced action, are processed by a runner. As a result, you can use runner environment variables here, using the appropriate syntax for the shell you are using on the runner - for example, `$NAME` for the bash shell on a Linux runner, or `$env:NAME` for PowerShell on a Windows runner. In most cases you can also use contexts, with the syntax `${{ CONTEXT.PROPERTY }}`, to access the same value. The difference is that the context will be interpolated and replaced by a string before the job is sent to a runner.
However, you cannot use runner environment variables in parts of a workflow that are processed by GitHub Actions and are not sent to the runner. Instead, you must use contexts. For example, an `if` conditional, which determines whether a job or step is sent to the runner, is always processed by GitHub Actions. You must therefore use a context in an `if` conditional statement to access the value of a variable.
YAML
name: Conditional env variable
on: workflow_dispatch
env:
DAY_OF_WEEK: Monday
jobs:
greeting_job:
runs-on: ubuntu-latest
env:
Greeting: Hello
steps:
- name: "Say Hello Mona it's Monday"
if: ${{ env.DAY_OF_WEEK == 'Monday' }}
run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!"
env:
First_Name: Mona
`name: Conditional env variable
on: workflow_dispatch
env:
DAY_OF_WEEK: Monday
jobs:
greeting_job:
runs-on: ubuntu-latest
env:
Greeting: Hello
steps:
- name: "Say Hello Mona it's Monday"
if: ${{ env.DAY_OF_WEEK == 'Monday' }}
run: echo "$Greeting $First_Name. Today is $DAY_OF_WEEK!"
env:
First_Name: Mona
`
In this modification of the earlier example, we've introduced an `if` conditional. The workflow step is now only run if `DAY_OF_WEEK` is set to "Monday". We access this value from the `if` conditional statement by using the `env` context. The `env` context is not required for the variables referenced within the `run` command. They are referenced as runner environment variables and are interpolated after the job is received by the runner. We could, however, have chosen to interpolate those variables before sending the job to the runner, by using contexts. </excerpt>

# Contexts reference
Find information about contexts available in GitHub Actions workflows, including available properties, access methods, and usage examples.
## Available contexts
Context name | Type | Description
--- | --- | ---
`github` | `object` | Information about the workflow run. For more information, see `github` context.
`env` | `object` | Contains variables set in a workflow, job, or step. For more information, see `env` context.
`vars` | `object` | Contains variables set at the repository, organization, or environment levels. For more information, see `vars` context.
`job` | `object` | Information about the currently running job. For more information, see `job` context.
`jobs` | `object` | For reusable workflows only, contains outputs of jobs from the reusable workflow. For more information, see `jobs` context.
`steps` | `object` | Information about the steps that have been run in the current job. For more information, see `steps` context.
* Property dereference syntax: `github.sha`
In order to use property dereference syntax, the property name must start with a letter or `_` and contain only alphanumeric characters, `-`, or `_`.
If you attempt to dereference a nonexistent property, it will evaluate to an empty string.
### Determining when to use contexts
GitHub Actions includes a collection of variables called contexts and a similar collection of variables called default variables. These variables are intended for use at different points in the workflow:
* Default environment variables: These environment variables exist only on the runner that is executing your job. For more information, see Variables reference.
* Contexts: You can use most contexts at any point in your workflow, including when default variables would be unavailable. For example, you can use contexts with expressions to perform initial processing before the job is routed to a runner for execution; this allows you to use a context with the conditional `if` keyword to determine whether a step should run. Once the job is running, you can also retrieve context variables from the runner that is executing the job, such as `runner.os`. For details of where you can use various contexts within a workflow, see Context availability.
The following example demonstrates how these different types of variables can be used together in a job:
YAML
name: CI
on: push
jobs:
prod-check:
if: ${{ github.ref == 'refs/heads/main' }}
runs-on: ubuntu-latest
steps:
- run: echo "Deploying to production server on branch $GITHUB_REF"
`name: CI
on: push
jobs:
prod-check:
if: ${{ github.ref == 'refs/heads/main' }}
runs-on: ubuntu-latest
steps:
- run: echo "Deploying to production server on branch $GITHUB_REF"
`
In this example, the `if` statement checks the `github.ref` context to determine the current branch name; if the name is `refs/heads/main`, then the subsequent steps are executed. The `if` check is processed by GitHub Actions, and the job is only sent to the runner if the result is `true`. Once the job is sent to the runner, the step is executed and refers to the `$GITHUB_REF` variable from the runner.

# Contexts
Learn about contexts in GitHub Actions.
## About contexts
Contexts are a way to access information about workflow runs, variables, runner environments, jobs, and steps. Each context is an object that contains properties, which can be strings or other objects.
Contexts, objects, and properties will vary significantly under different workflow run conditions. For example, the `matrix` context is only populated for jobs in a matrix.
You can access contexts using the expression syntax. For more information, see Evaluate expressions in workflows and actions.
`${{ <context> }}`
Warning
When creating workflows and actions, you should always consider whether your code might execute untrusted input from possible attackers. Certain contexts should be treated as untrusted input, as an attacker could insert their own malicious content. For more information, see Secure use reference.

# Expressions
You can evaluate expressions in workflows and actions.
## About expressions
You can use expressions to programmatically set environment variables in workflow files and access contexts. An expression can be any combination of literal values, references to a context, or functions. You can combine literals, context references, and functions using operators. For more information about contexts, see Contexts reference.
Expressions are commonly used with the conditional `if` keyword in a workflow file to determine whether a step should run. When an `if` conditional is `true`, the step will run.
You need to use specific syntax to tell GitHub to evaluate an expression rather than treat it as a string.
`${{ <expression> }}`
Note
The exception to this rule is when you are using expressions in an `if` clause, where, optionally, you can usually omit `${{` and `}}`. For more information about `if` conditionals, see Workflow syntax for GitHub Actions.
Warning
When creating workflows and actions, you should always consider whether your code might execute untrusted input from possible attackers. Certain contexts should be treated as untrusted input, as an attacker could insert their own malicious content. For more information, see Secure use reference.

You can use the `if` conditional to prevent a step from running unless a condition is met. You can use any supported context and expression to create a conditional. For more information on which contexts are supported in this key, see Contexts reference.
When you use expressions in an `if` conditional, you can, optionally, omit the `${{ }}` expression syntax because GitHub Actions automatically evaluates the `if` conditional as an expression. However, this exception does not apply everywhere.
You must always use the `${{ }}` expression syntax or escape with `''`, `""`, or `()` when the expression starts with `!`, since `!` is reserved notation in YAML format. For example:
`if: ${{ ! startsWith(github.ref, 'refs/tags/') }}
`
For more information, see Evaluate expressions in workflows and actions.
### Example: Using contexts
This step only runs when the event type is a `pull_request` and the event action is `unassigned`.
`steps:
- name: My first step
if: ${{ github.event_name == 'pull_request' && github.event.action == 'unassigned' }}
run: echo This event is a pull request that had an assignee removed.
`
### Example: Using status check functions
The `my backup step` only runs when the previous step of a job fails. For more information, see Evaluate expressions in workflows and actions.
`steps:
- name: My first step
uses: octo-org/action-name@main
- name: My backup step
if: ${{ failure() }}
uses: actions/heroku@1.0.0
`
### Example: Using secrets
Secrets cannot be directly referenced in `if:` conditionals. Instead, consider setting secrets as job-level environment variables, then referencing the environment variables to conditionally run steps in the job.
If a secret has not been set, the return value of an expression referencing the secret (such as `${{ secrets.SuperSecret }}` in the example) will be an empty string.
`name: Run a step if a secret has been set
on: push
jobs:
my-jobname:
runs-on: ubuntu-latest
env:
super_secret: ${{ secrets.SuperSecret }}
steps:
- if: ${{ env.super_secret != '' }}
run: echo 'This step will only run if the secret has a value set.'
- if: ${{ env.super_secret == '' }}
run: echo 'This step will only run if the secret does not have a value set.'
`

Configuration variables at the environment level are automatically available after their environment is declared by the runner. ... uses: actions/hello-world-javascript-action@main
## `env` context
The `env` context contains variables that have been set in a workflow, job, or step. It does not contain variables inherited by the runner process. For more information about setting variables in your workflow, see Workflow syntax for GitHub Actions.
You can retrieve the values of variables stored in `env` context and use these values in your workflow file. You can use the `env` context in any key in a workflow step except for the `id` and `uses` keys. For more information on the step syntax, see Workflow syntax for GitHub Actions.
If you want to use the value of a variable inside a runner, use the runner operating system's normal method for reading environment variables.
Property name | Type | Description
--- | --- | ---
`env` | `object` | This context changes for each step in a job. You can access this context from any step in a job. This object contains the properties listed below.
`env.<env_name>` | `string` | The value of a specific environment variable.
### Example contents of the `env` context
The contents of the `env` context is a mapping of variable names to their values. The context's contents can change depending on where it is used in the workflow run. In this example, the `env` context contains two variables.
`{
"first_name": "Mona",
"super_duper_var": "totally_awesome"
}
`
### Example usage of the `env` context
This example workflow shows variables being set in the `env` context at the workflow, job, and step levels. The `${{ env.VARIABLE-NAME }}` syntax is then used to retrieve variable values within individual steps in the workflow.
When more than one environment variable is defined with the same name, GitHub uses the most specific variable. For example, an environment variable defined in a step will override job and workflow environment variables with the same name, while the step executes. An environment variable defined for a job will override a workflow variable with the same name, while the job executes.

<excerpt>citeturn0search1 [wordlim: 200] Crawled: yesterday; We access this value from the `if` conditional statement by using the `env` context. ... {% data reusables.actions.actions-vars-context-example-usage %} ... Once the job is sent to the runner, the step is executed and the environment variable in the `echo` command is interpolated using the appropriate syntax (`$env:NAME` for PowerShell on Windows, and `$NAME` for bash and sh on Linux and macOS). ... If you generate a value in one step of a job, you can use the value in subsequent steps of the same job by assigning the value to an existing or new environment variable and then writing this to the `GITHUB_ENV` environment file.
For example, an `if` conditional, which determines whether a job or step is sent to the runner, is always processed by {% data variables.product.prodname_actions %}. You must therefore use a context in an `if` conditional statement to access the value of a variable.

<excerpt>citeturn0search2 [wordlim: 200] Crawled: 2 weeks ago; You can access contexts using the expression syntax. ... For example, you can use contexts with expressions to perform initial processing before the job is routed to a runner for execution; this allows you to use a context with the conditional `if` keyword to determine whether a step should run. ... In this example, the `if` statement checks the `github.ref` context to determine the current branch name; if the name is `refs/heads/main`, then the subsequent steps are executed. The `if` check is processed by {% data variables.product.prodname_actions %}, and the job is only sent to the runner if the result is `true`.
For more information, see AUTOTITLE.
* Contexts: You can use most contexts at any point in your workflow, including when default variables would be unavailable. For example, you can use contexts with expressions to perform initial processing before the job is routed to a runner for execution; this allows you to use a context with the conditional `if` keyword to determine whether a step should run. Once the job is running, you can also retrieve context variables from the runner that is executing the job, such as `runner.os`. For details of where you can use various contexts within a workflow, see AUTOTITLE.
The following example demonstrates how these different types of variables can be used together in a job:
{% raw %}
name: CI
on: push
jobs:
prod-check:
if: ${{ github.ref == 'refs/heads/main' }}
runs-on: ubuntu-latest
steps:
- run: echo "Deploying to production server on branch $GITHUB_REF"
{% endraw %}
In this example, the `if` statement checks the `github.ref` context to determine the current branch name; if the name is `refs/heads/main`, then the subsequent steps are executed. The `if` check is processed by {% data variables.product.prodname_actions %}, and the job is only sent to the runner if the result is `true`. Once the job is sent to the runner, the step is executed and refers to the `$GITHUB_REF` variable from the runner.</excerpt>

<excerpt>citeturn0search4 [wordlim: 200] Crawled: last week; In order to use property dereference syntax, the property name must start with a letter or `_` and contain only alphanumeric characters, `-`, or `_`. ... For example, you can use contexts with expressions to perform initial processing before the job is routed to a runner for execution; this allows you to use a context with the conditional `if` keyword to determine whether a step should run. ... `jobs.<job_id>.steps.if` | `github, needs, strategy, matrix, job, runner, env, vars, steps, inputs` | `always, cancelled, success, failure, hashFiles` ... `github` | `object` | The top-level context available during any job or step in a workflow. ... To make this context work with composite actions, reference it within the `env` context of the composite action.
* Property dereference syntax: `github.sha`
In order to use property dereference syntax, the property name must start with a letter or `_` and contain only alphanumeric characters, `-`, or `_`.
If you attempt to dereference a nonexistent property, it will evaluate to an empty string.
### Determining when to use contexts
GitHub Actions includes a collection of variables called contexts and a similar collection of variables called default variables. These variables are intended for use at different points in the workflow:
* Default environment variables: These environment variables exist only on the runner that is executing your job. For more information, see Variables reference.
* Contexts: You can use most contexts at any point in your workflow, including when default variables would be unavailable. For example, you can use contexts with expressions to perform initial processing before the job is routed to a runner for execution; this allows you to use a context with the conditional `if` keyword to determine whether a step should run. </excerpt>

Limit Docker Hub credentials to image loading. The job-level secrets are available to toolchain installation, build, chart preparation, and certification steps. Same-repository pull requests, pushes, and manual runs can receive these secrets; fork pull requests normally cannot. The proposed login placement is incorrect because authentication must occur before docker pull.
A step-level env is available to that step’s if through the env context, so the existing guard is valid. Add logout after image loading and before certification.

Include compatibility target images in images.txt.
airgap_prepare collects image: values but does not collect rolling_*_test_tag or rollback_from_tag. The compatibility tests combine those tags with the deployed image repository before calling set_image. A user who loads only the documented images.txt can therefore run an offline rollout or rollback that requests an unloaded image and waits for the rollout timeout. Extend preparation to add every configured compatibility target image.

Block or test runner egress during certification.
These DOCKER-USER rules restrict forwarded kind traffic. They do not restrict the runner that executes ./cnti-testsuite setup, cnf_install, and cert. If a host-side code path bypasses the offline artifact helper, its network request can succeed, and this job can report a passing air-gap run. Isolate the suite process after bundle preparation, or add a host-side egress check. The pod check alone cannot establish that the host-side run is offline. (docs.docker.com)

Use the configured Litmus mirror when preparing fault artifacts.
If CNTI_TESTSUITE_CHAOS_CHARTS_URL selects a mirror, airgap_prepare caches faults under the fixed upstream URLs. LitmusManager.install_fault later requests the mirror URLs, so the URL-keyed offline cache reports those faults as missing. Build preparation URLs with LitmusManager.chaos_charts so both paths use the same cache keys. (raw.githubusercontent.com)

Add an offline bundle and cache for every host-side download, so a run can
resolve Helm, Kubescape, the Kyverno CLI and policies, the Litmus operator
and fault manifests, and the Kyverno policies without network access.
- Add Offline and Airgap helpers, airgap_prepare/airgap_status, recursive
CNF manifest scanning, and cached image collection.
- Fail missing downloads with the URL and bundle path, and skip
registry-only checks with a reason instead of waiting on a timeout.
- Patch cached Litmus manifests to use local images and include the
operator's CHAOS_RUNNER_IMAGE in the collected image list.
- Add the airgap workflow: GitHub-hosted runner, kind cluster, blocked
egress, preloaded images, and an offline cert run.
- Document the bundle and the two offline environment variables, and fix
the Renovate image regex for the ClusterTools constant.
Verified with crystal build, the airgap/offline specs, and a local
airgap_prepare smoke test.

Match the GitHub host exactly before sending GITHUB_TOKEN.
headers_for checks url.includes?("github.com") against the whole URL string. fault_url builds URLs from LitmusManager.chaos_charts, which an operator can point at a mirror through CNTI_TESTSUITE_CHAOS_CHARTS_URL. A mirror such as https://artifactory.corp/github.com-remote/chaos-charts matches the substring check. airgap_prepare then sends Authorization: Bearer $GITHUB_TOKEN to that non-GitHub host.
