* fix(manager): handle registryAliases with shell variable defaults
Allows `registryAliases` keys to contain shell-style variables with
empty (or other) defaults, e.g. `${DEPENDENCY_PROXY:-}` or
`${CI_REGISTRY:-}`. The same image string is then resolved both
online (variable expanded) and offline (variable empty).
Changes in `dockerfile/extract.ts` (used by `gitlabci` too):
* Match the alias key as either `${name}/...` (existing) or `${name}...`
when `name` already ends in a non-identifier boundary character such
as `}`. Bare-identifier keys like `$CI_REGISTRY` continue to require
the slash boundary so they no longer overmatch keys that begin with
the same prefix (e.g. `$CI_REGISTRY` vs `$CI_REGISTRY_IMAGE`).
* Use `ensureTrailingSlash` to handle alias values that already include
a trailing slash.
* Preserve the original `name` and path structure in `dep.depName`
instead of substringing only after the alias `value`. This keeps the
variable in the depName so it survives a `splitImageParts` round-trip
and the resulting branch name comes out clean.
Adds `sanitizeDepName` regex passes in
`lib/workers/repository/updates/flatten.ts` so any leftover
`${VAR}`/`${VAR:-...}` placeholder is stripped from the depName before
it becomes a branch name (otherwise we'd get
`renovate/${dependency_proxy}python-3.x` instead of
`renovate/python-3.x`).
Tests cover:
* `${VAR:-}/image` (with slash) and `${VAR:-}image` (no slash, requires
the boundary form).
* Overlapping prefixes: `$CI_REGISTRY` vs `$CI_REGISTRY_IMAGE`.
* Registry alias with port (`localhost:5000/repo`).
* `sanitizeDepName` strips `${VAR}` / `${VAR:-}` / bare `$VAR`.
Reproducer: https://github.com/Wayneoween/renovate-36293-repro
* revert(manager/gitlabci): keep regex group name as 'prefix'
Reverting the unrelated `prefix` -> `rawPrefix` rename in `depProxyRe`.
Per review on #36293, this rename is out of scope for the registry-alias
fix and just adds review surface.
* refactor(manager/dockerfile): narrow alias boundary check to '}'
Per review on #36293. The previous regex `/[^A-Za-z0-9_]$/` matched any
non-word ending, which is broader than the documented case (alias keys
ending in `}` from `${VAR}` / `${VAR:-...}`). Replace with a plain
`name.endsWith('}')` check, which also avoids re-building a regex on
every iteration of the alias loop.
Existing tests (`'variables with default and slash'`,
`'variables with default no slash'`, `'alias with digest only'`)
continue to exercise the `}`-boundary path; the `'overlapping prefixes'`
case continues to exercise the slash-only path.
* chore(manager/dockerfile): trim comment and TODO library/ strip edge
Per review on #36293:
* Drop the verbose explanation block above the depName-restore branch;
the spec rows already document the expected shape.
* Add a TODO above the `dep.depName?.startsWith(valueWithSlash)` guard
noting a pre-existing edge case: when the inner `getDep` strips a
`library/` prefix (or similar) the depName no longer starts with
`valueWithSlash`, so the alias-rooted depName is not restored. Out of
scope for this PR.
* fix(manager/dockerfile): handle empty registry alias value
- strip trailing slash after ${VAR} placeholders in sanitizeDepName
- treat an empty registry alias value as Docker Hub instead of '/'
- clarify registry alias docs wording
* refactor(manager/dockerfile): drop redundant alias boundary guard
- `matchedAtBoundary` is only read behind `!matchedWithSlash`
- add docker-compose test for `${VAR:-}` registry aliases
* test(manager/dockerfile): pin special-prefix registry alias behavior
`getDep` strips `library/`, `amd64/` and `arm64/` as special prefixes, so
an alias whose value is one of those loses its alias-rooted `depName`.
Both the slash form and the variable form behave this way on `main`.
* feat(manager/gitlabci): add support for CI_REGISTRY
* fix: pass correct property
* chore: adapt tests
* docs; add documentation for the new option
* test: extend test cases
* fix: do the abc properly
* refactor: switch to using registryAliases option
* docs: mention registry variable
* style: remove extra heading
* docs: fix sentence
