Is "pull: true" necessary? #287

mathisdt commented 2025年12月07日 19:13:14 +01:00

I created a build helper image to speed up my builds (packages were installed onto ubuntu:noble in every pipeline run, which was a waste of resources).

Now I want to use it in my other builds and was wondering if I have to add pull: true for the build helper image to be updated after I rebuild it once a month. Is there a cache policy for images on Woodpecker? If so, how long are images kept and not re-fetched?

To my knowledge, none.

Yeah if the tag doesn't changes then pull: true is necessary as the image will not be deleted from cache. Another option would be to publish the build image with a newer tag and then use something like https://docs.renovatebot.com/ to update the tag in all the repository you use this to the newer tag.

@Gusted Thank you, that helps a lot!

The tag should stay "latest", so I'll include pull: true. I already use Renovate for dependency updates, but I don't want one PR every month for every project just to use the current build helper image.
