We´ve migrated an existing Repository to make use of GIT-LFS.
The Repository is hosted at BitBucket Cloud while the bamboo server (latest version) is self-hosted behind a secured connection (vpn).
We´re using the Bamboo Source Code Checkout Task.
Bamboo uses a cached repository (/build-dir/_git-repositories-cache/...) to fasten the build process.
The initial clone to this cached repository path seems to work, all lfs files are downloaded successfully (as seen in the bamboo build log).
We tested this multiple times by flushing the cached repository contents and restart the process.
As far as we understand the bamboo source code checkout process the next step is to checkout the sources in the bamboo build dir
(in our case /build-dir/FSCWEB-FSCWEBSYMFONY-SS). The source code checkout (using a git remote pointing to file://CACHED_REPO)
works but after downloading the LFS files, which seems to work:
>> Git LFS: (31838 of 31838 files) 2.40 GB / 2.40 GB
the logs shows errors:
>> error: cannot feed the input to external filter true
>> error: external filter true failed
After the sourcode checkout task is finished, the pure git files are availale.
But the lfs files are missing (not existing in the filesystem) or have a incorrect filesize (0 or are very low and incorrect size).
This leads to multiple problems:
- git status or git lfs status shows many modified or deleted files (all from the lfs storage)
- the build process does not work as the files are required by following build stages.
Our current solution is to remove all files from the bamboo build dir and do a manually git-lfs clone from the bitbucket cloud repo url.
This downloads all files successfully (correct size, no git working dir changes after the clone). Then we start the bamboo build plan.
We´ve not tested to manipulate lfs files yet.
The git-lfs clone from the bitbucket repository works without problems at multiple developer machines, so the problem seems to be located at bamboo.
Our main question:
- How to fix the described problem?
Further questions:
- how does the bamboo git-lfs checkout task work in detail?
- Is a git-lfs clone used?
- Why does bamboo change the git remote url to file://CACHED_DIR during build instead of using the original Bitbucket Cloud url?
