Remove RAILPACK_FRONTEND_IMAGE env var from helper Dockerfile and resolve
the image ref at runtime using a new `railpack_version` constant in config.
Eliminates Docker build-time env interpolation for BUILDKIT_SYNTAX arg.
Extract NIXPACKS_/RAILPACK_ prefix filtering into a reusable
`scopeWithoutBuildpackControlVariables` query scope on EnvironmentVariable.
Apply scope consistently to runtime vars, runtime preview vars, and
buildtime var generation in ApplicationDeploymentJob.
Refactor `generate_railpack_env_variables` to return a Collection.
Add `RAILPACK_FRONTEND_IMAGE` constant and bake it into the
coolify-helper Dockerfile as a build arg.
Add DevelopmentRailpackExamplesSeeder (dev/local env only) for
seeding example Railpack apps, wired into DatabaseSeeder.
Add tests:
- ApplicationDeploymentControlVarFilteringTest: verifies control vars
are excluded from runtime and buildtime envs
- DevelopmentRailpackExamplesSeederTest: verifies seeder behavior
- ApplicationDeploymentRailpackEnvParityTest: parity checks for env
handling across build/runtime paths
The production Dockerfile already runs apk upgrade at build time.
The helper and realtime Dockerfiles were missing this step.
The helper (Alpine 3.21) ships with CVE-2025-15467 in OpenSSL 3.3.5.
The realtime (Alpine 3.18) has outdated OpenSSL 3.1.2 with HIGH CVEs.
Adding apk upgrade before apk add makes both images consistent
with the production Dockerfile.
Extract build_railpack_static_image() into its own method, prevent port
override when is_static is set, bump Railpack to 0.22.0, and improve
test setup with beforeEach and correct polymorphic env var fields.
