Docker build in pipelines doesn't cache build process?

msvoren

Is there a way to cache build process for docker build?

Now, everytime the build is started, it downloads the parent image again and build goes through every Dockerfile command all over again, so the build in whole stretches up to 6 minutes.

Docker engine is capable of caching images and build commands that weren't changed.

I couldn't find any documentation on docker cashing ( found the ones for npm for example ). Is there a support for this but it's not documented ? Or, if not, is this somewhere in the Pipelines roadmap?

THanks a lot!

Hey @msvoren,

Not at this time; follow https://bitbucket.org/site/master/issues/14144/cache-docker-layers-between-builds to get updates as we implement this feature.

This feature has been shipped for customers to use here is the details on how to opt-in to this docker layer cache.

pipelines:
  default:
    services:
      - docker
    caches:
      - docker
    script:
      - # .. do cool stuff with Docker ..

Hi @Trevor Mack (He/Him),

Probably this feature does not correctly work, for example in my pipeline it caches only 2 layers:

Bump!

Did you get this to work?

I got my docker builds caching but after doing a merge a week later, looks like the caches don't last longer than a week https://support.atlassian.com/bitbucket-cloud/docs/cache-dependencies/
