Generation must therefore statically lay out every build/publish/test +step the deployment could need, in dependency order, batched into parallel +groups, with the pieces that can only be known at pipeline-run time (which +images already exist, what the registry currently resolves to) left as +Codefresh's own `${{VAR}}` pipeline-variable references rather than baked-in +values - a value resolved at generation time instead would silently go stale +the next time that variable changes without a matching regeneration. + +CH model concepts this relies on: +- CHProject.involved_apps / `CHApp.is_buildable` scope build+publish steps to + what's actually deployed and buildable, the same closure skaffold.py uses. +- CHProject._combined_dependencies gives each build step's `dependencies:` + (explicit harness.dependencies.build plus the Dockerfile's own guessed + FROM/ARG chain), used both for build args and for ordering. +- Every task under an involved app and every base image in the project gets + its own build+publish step unconditionally, regardless of whether its + owning app is itself deployed - codefresh always builds/publishes the full + image universe a deployment might later reuse, a wider net than skaffold's + manage_task_images gate. +- app.test.unit/api/e2e (commands, autotest, checks, run_params, smoketest/ + console/request-error flags) and app.openapi.server_urls drive the unit, + API and E2E test steps; app.harness_config (subdomain, secured, accounts) + drives their domain URLs, credentials and the gatekeeper/rollout-wait + commands. +- app.secrets/app.database and CHDeployConfig.registry_secret_name decide + which cloudharness-managed secret/connect-string/registry-secret values + need exporting into the deployment step's custom_values, each as a + reference to a Codefresh pipeline variable, not a resolved value. +- app.git_dependencies become pre-build git-clone steps. +- CHDeployConfig (includes/excludes/envs/local/debug/secured_gatekeepers) + holds the deployment-target knobs substituted into prepare_deployment's + harness-deployment command and the build args. +- pipeline_relative_path rewrites any path that crosses the project's own + root into the literal "cloud-harness/..." alias - codefresh.yaml is + committed and may run against a differently laid out checkout, unlike a + skaffold.yaml path (consumed immediately, same machine, real path only). + +CHCodefresh.generate() algorithm: + +1. Start from the merged codefresh-template.yaml (CH default + project + override, composed across the full project layer chain). +2. For every involved, buildable app: collect a build step (qualified image, + Dockerfile, alias-rewritten working_directory, DEBUG/source_images/ + dependency build args, a cache-busting NOCACHE arg, a skip-when condition + keyed off that image's already-exists/force-rebuild pipeline variables) + and a matching publish step (skip-when a per-app publish-skip variable is + set, tagged with DEPLOYMENT_PUBLISH_TAG and latest). +3. Every task of every involved app, and every base image in the project, + gets the same build+publish step pair unconditionally (step 2's gating + doesn't apply to them). +4. Unit test steps: one per buildable app with test.unit.commands, run + inside that app's own freshly-tagged image. +5. API/E2E test steps: one scale entry per buildable app with test.api/ + test.e2e enabled and a subdomain (schemathesis/pytest commands or + test/e2e volume mounts, a domain URL, and env for credentials/smoketest/ + console/request-error flags). The shared test-api/test-e2e runner image + only gets a build step and its image wired in if at least one app + contributed a scale entry; otherwise the whole container step is pruned. +6. Git-clone steps: one per app's declared git_dependencies, host-detected + (github/gitlab/bitbucket) and working-directory-rewritten the same way + build steps are. +7. Build steps are batched into dependency-ordered parallel groups - a step + only joins a group once every build it depends on is already in an + earlier group. A dependency cycle (which legacy recurses forever on) is + dumped into one final group instead. +8. Deployment-adjacent wiring: wait_deployment gets a kubectl rollout-status + command per auto-deployed app/gatekeeper; the deployment step's + custom_values get one entry per secret/connect-string/registry-secret + value that needs exporting from Codefresh's own pipeline variables; + prepare_deployment's harness-deployment command gets its $ENV/$PARAMS/ + $PATHS placeholders substituted from the project's env list, include/ + exclude config and layered root paths. +9. Every step left falsy (an unfilled template placeholder) or an empty + parallel container is pruned, matching legacy's own "remove useless + steps" filter; surviving parallel containers get their inner steps + key-sorted for a stable diff; if the template declares a `stages` list, + the whole step dict is finally re-ordered to match it. +10. Every image reference emitted anywhere (build/publish/test/task args) + uses the literal `${{REGISTRY}}` pipeline-variable placeholder + (CHCodefresh.qualify), never a concretely resolved registry string - see + the module-level rationale above. + +write_env_file() is a separate, related entry point: it writes the +per-image TAG/EXISTS variables (consumed by step 2's skip-when condition and +step 8's $PATHS-adjacent exports) at *pipeline run time*, by checking what +already exists in the registry - never at generation time, since that's +exactly the kind of fact that can't be baked into
