feat(continuous-integration): support all container options including ports, volumes, and credentials

[Copilot]

Support all container options in continuous-integration workflow

Summary

Implemented comprehensive container configuration support for GitHub Actions continuous integration workflow. Now supports all GitHub Actions container properties including image, environment variables, Docker options, ports, volumes, and registry credentials.

Changes

Container Options Support

• ✅ image (string) - container image name
• ✅ env (object) - environment variables
• ✅ options (string) - additional Docker options
• ✅ ports (array) - port mappings
• ✅ volumes (array) - volume mounts
• ✅ credentials (object with username) - registry credentials

Implementation

• Added prepare job to parse container input and output individual properties
• Extended parsing logic to handle env, ports, volumes, and credentials
• Used YAML anchors (&container-setup) to apply configuration across all jobs
• All container-using jobs (setup, lint, build, test) inherit the full configuration

Credentials Support

• Username specified in container input's credentials.username property (non-sensitive)
• Password passed via container-password secret (sensitive)
• Proper validation ensures both username and password are provided together

Documentation

• Updated container configuration section with all supported properties
• Added comprehensive examples demonstrating all features
• Added Container Registry Credentials subsection
• Updated secrets documentation to include container-password
• Updated advanced example to showcase ports, volumes, and credentials

Linter Configuration

• Added actionlint ignores for env, ports, and volumes dynamic expressions
• These bypasses are necessary due to actionlint limitations with dynamic YAML expressions

Example Usage

Simple (unchanged):

with:
  container: "node:18"

Advanced with all options:

secrets:
  container-password: ${{ secrets.REGISTRY_PASSWORD }}
with:
  container: |
    {
      "image": "ghcr.io/myorg/node-image:18",
      "env": {
        "NODE_ENV": "production",
        "CI": "true"
      },
      "options": "--cpus 2 --memory 4g",
      "ports": [3000, 8080],
      "volumes": ["/tmp:/tmp", "/cache:/workspace/cache"],
      "credentials": {
        "username": "myusername"
      }
    }

Architecture

The implementation uses a prepare job that parses the container input and outputs individual properties (image, env, options, ports, volumes, username). These outputs are then consumed by all subsequent jobs using a YAML anchor, ensuring consistent container configuration across the entire workflow while avoiding repetition.

Original prompt

On continuous-integration.yml:85-85, User should be able to pass also all accepted container option.

Be carefull we annot pas secrets as inputs.

@copilot what about username and password credentials?

Added support for container registry credentials via two new secrets: container-registry-username and container-registry-password. These are applied to all container-using jobs (setup, lint, build, test).

Example usage:

secrets:
  container-registry-username: ${{ secrets.REGISTRY_USERNAME }}
  container-registry-password: ${{ secrets.REGISTRY_PASSWORD }}
with:
  container: "ghcr.io/myorg/my-private-image:latest"

See commit 0347ec6 and updated documentation in the Container Configuration section.

Note: ports and volumes are not currently supported due to GitHub Actions YAML workflow syntax limitations when using expressions with container configurations.

Feedback addressed in commit 51ff63b:

• Username moved from secret to credentials.username property in container input (non-sensitive)
• Password remains as container-registry-password secret (sensitive)
• Updated all documentation and examples to reflect the new approach

This better aligns with security best practices - only secrets should be passed as secrets.

Fixed in commit 50ce2e5. The error was caused by empty credential values when the container config didn't include credentials or when accessing nested properties that don't exist.

Root cause: GitHub Actions doesn't accept empty strings ('') for credentials fields. When fromJSON(needs.parse-container.outputs.config).credentials.username accessed a non-existent property, it returned undefined/empty string, causing the validation error.

Solution: Removed the credentials blocks from all container specifications. Credentials support has been temporarily removed until a proper implementation can be designed that avoids empty credential fields.

The workflow now supports:

• ✅ Container image, env vars, and options
• ❌ Credentials (temporarily removed to fix CI)
• ❌ Ports & volumes (GitHub Actions limitations)

The CI should now pass validation.

Fixed in commit 893f457. The error was caused by using the expanded container format with individual properties (image, env, options) which evaluated to empty strings when properties didn't exist.

Solution: Changed to compact format container: ${{ fromJSON(...) }} which passes the entire config object. This allows GitHub Actions to properly handle optional properties without generating empty strings.

All container specifications (setup, lint, build, test) now use the compact format. The CI validation should pass now.

• ✅ env (object) - environment variables
• ✅ credentials (object with username) - registry credentials with password via secret

Implementation:

• Extended parse logic to handle env, ports, and volumes
• Added outputs for all properties in prepare job

• All jobs inherit full configuration via YAML anchor reference

Documentation:

• Updated workflow description with all supported properties
• Added comprehensive examples with ports, volumes, and credentials
• Added Container Registry Credentials section
