@crazy-max Not sure why Netlify tests are failing with 'Failed during stage 'building site': Build script returned non-zero exit code: 1 (https://ntl.fyi/exit-code-1)`. Here's the log - https://app.netlify.com/sites/docsdocker/deploys/63511a4faa348f0ae9b09e88

Do you mind taking a quick look? Thanks

@usha-mandya I think that's the same issue as last time, the branch needs to be rebased.

Thanks for sharing the update. Closing this PR as this content no longer exists in the docs repo. Most of the samples have moved to https://github.com/docker/awesome-compose
