Microsoft Devcontainer Bump

[rfpludwick]

How are you running Renovate?

Self-hosted Renovate

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

GitHub & Gitea, Always Latest Version

Please tell us more about your question or problem

I have a Dockerfile which I use to build my own flavor of devcontainer. Renovate seems unable to determine that there are newer versions of the devcontainer available in the registry. Pertinent Dockerifle snippet:

FROM mcr.microsoft.com/vscode/devcontainers/base:ubuntu-22.04

I'm unsure how to resolve this so Renovate will correctly see that mcr.microsoft.com/vscode/devcontainers/base:ubuntu-24.04 exists.

you need to override versioning.

• use regex versioning
• use Ubuntu versioning with version compatibility

Thanks, that did the trick. I forgot all about having to put the compatibility into a regex; I've done that elsewhere. For those who want to know the configuration I added:

packageRules: [
	{
		matchDatasources: [
			"docker",
		],
		matchPackageNames: [
			"mcr.microsoft.com/vscode/devcontainers/base",
		],
		versioning: "regex:^(?<compatibility>[^-]+)-(?<major>\\d+)\\.(?<minor>\\d+)$",
	},
],

version compatibility with Ubuntu versioning is probably a better solution
