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
Use Railpack's install env handling and dedicated CLI flags for build/start overrides, and forward install commands into docker build secrets so image builds stay aligned with prepare-time configuration. Update the railpack config test to cover the new command format.
- Implement railpack.json + generated config deep merging logic in
ApplicationDeploymentJob with JSON validation and assoc array checks
- Label Railpack as "Beta" in all build pack selectors and show a
visible beta badge when railpack is selected in new-app forms
- Add railpack-nodejs Fastify example to ApplicationSeeder
- Add ApplicationSeederTest and ApplicationDeploymentRailpackConfigTest
covering config merge behavior and seeder correctness
