Jamie Tanna 9b87f8de2f feat(manager/dockerfile): extract apk add packages from RUN instructions (#45691)
* feat(manager/dockerfile): extract `apk add` packages from `RUN` instructions

As noted in #43711, users pin APK packages in their Dockerfiles and want
Renovate to update them, which so far has needed a custom manager[0].

Now that we have the `apk` datasource, we can extract these ourselves,
and parse the `RUN` instruction more effectively than a regex can.

We can do this by:

- extracting `apk add` dependencies when processing a `Dockerfile`
- ignoring common flags to `apk` before we extract the dependency names,
  which wasn't straightforward with a Custom Manager
- ignoring i.e. `--virtual .build-deps`
- handle example cases from [0] and other usages i.e. with a comment in
  between lines
- ensure that `final` doesn't run against the final `apk` install
- removing the docs for how to do this with a Custom Manager, as that
  complexity is no longer needed
- skipping `unspecified-version` and `contains-variable`

We inform the user that they will need to override the `registryUrls`,
as we already have a default on the `apk` datasource and can't override
it in a straightforward means.

Find the command by name wherever it sits in the tokens, rather than
skipping an allowlist of shell keywords and variable assignments, so that
a wrapper program like `sudo`, `chroot /mnt` or `timeout 30` is handled
too.

What is the Mend Renovate CLI?

Renovate is an automated dependency update tool. It helps to update dependencies in your code without needing to do it manually. When Renovate runs on your repo, it looks for references to dependencies (both public and private) and, if there are newer versions available, Renovate can create pull requests to update your versions automatically.

Features

  • Delivers update PRs directly to your repo
    • Relevant package files are discovered automatically
    • Pull Requests automatically generated in your repo
  • Provides useful information to help you decide which updates to accept (age, adoption, pass rates, merge confidence)
  • Highly configurable and flexible to fit in with your needs and repository standards
  • Largest collection of languages and platforms (listed below)
  • Connects with private repositories and package registries

Languages

Renovate can provide updates for most popular languages, platforms, and registries including: npm, Java, Python, .NET, Scala, Ruby, Go, Docker and more. Supports over 90 different package managers.

Platforms

Renovate updates code repositories on the following platforms: GitHub, GitLab, Bitbucket, Azure DevOps, AWS Code Commit (experimental), Gitea, Forgejo, Gerrit (experimental), SCM-Manager (experimental)

Ways to run Renovate

The most effective way to run Renovate is to use an automated job scheduling system that regularly runs Renovate on all enabled repositories and responds with priority to user activity. Mend offers cloud-hosted and self-hosted solutions. See the options below.

Mend Renovate Community (Cloud-Hosted)

Supports: GitHub.com, Bitbucket Cloud

Hosted by Mend.io. No setup is needed. Community plan available (Free)

  • GitHub Cloud: Install the Renovate Cloud-Hosted App on your GitHub org, then select the repos to enable
  • Bitbucket Cloud: Add the Mend App to your Workspace, then add the Mend Renovate user to the projects you want to enable

Mend Renovate Community (Self-hosted)

Supports: GitHub, GitLab, Bitbucket Data Center

Install and run your own Renovate server. Access internal packages.

Other ways to run Renovate

If you can’t use a pre-built job scheduling system, or want to build your own, the following options are available:

Run Renovate on your Pipeline

Mend provides a GitHub Action or a GitLab Runner to help you run Renovate as a CI pipeline job.

Run Renovate CLI

There are several ways to run the Renovate CLI directly. See docs: Running Renovate for all options.

Supports: all platforms

For additional community-maintained options, see the Community Tools page.
