How are you running Renovate?

Mend Renovate hosted app on github.com

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Please tell us more about your question or problem

The regex/custom manager doesn't apply registryAlias configuration to the registryUrl value (if present).

For example:

renovate.json

{
    "$schema": "https://docs.renovatebot.com/renovate-schema.json",
    "extends": [
        "config:base"
    ],
    "registryAliases": {
        "$CI_SERVER_URL": "https://gitlab.com",
        "https://$CI_SERVER_HOST": "https://gitlab.com"
    },
    "customManagers": [
        {
          "customType": "regex",
          "fileMatch": [".*\\.gitlab-ci\\.yml$"],
          "matchStrings": [
            "datasource=(?<datasource>.*?) depName=(?<depName>.*?) (versioning=(?<versioning>.*?))? (registryUrl=(?<registryUrl>.*?))?\\s.*?_VERSION:\\s*\"(?<currentValue>.*)\"\\s"
          ],
          "versioningTemplate": "{{#if versioning}}{{{versioning}}}{{else}}semver{{/if}}"
        }
    ]
}

and .gitlab-ci.yml

test:
  variables:
    # renovate: datasource=gitlab-tags depName=gitlab-com/gl-infra/common-ci-tasks versioning=semver registryUrl=https://${CI_SERVER_HOST}
    GITLAB_COMMON_CI_TASKS_VERSION: "v2.5.0"
    testing: "yes"

Renovate should report a version update being available, but instead the Dependency Dashboard shows a warning:

Renovate failed to look up the following dependencies: Failed to look up gitlab-tags package gitlab-com/gl-infra/common-ci-tasks.

Files affected: .gitlab-ci.yml

Renovate should apply the registry alias configuration in this case.

this is not a bug. only a few managers support registry aliases. it's documented

https://docs.renovatebot.com/configuration-options/#registryaliases
