Description of problem:
The s2i-go-pipeline-run fails during the Git clone phase when fetching the repository https://github.com/chmouel/go-simple-uploader.git using the Tekton git-init container. The failure occurs while running git fetch with --depth=1 and submodules enabled.
The error manifests as low-level filesystem I/O failures such as:
- fatal: fsync error on '.git/objects/pack/...': Input/output error
- fatal: write error: Bad file descriptor
- fatal: fetch-pack: invalid index-pack output
The failure has been observed across different base images (ubi7 and ubi9) and multiple pipeline runs using the same commit SHA, indicating a likely infrastructure or storage-related issue rather than a repository-specific problem.
Workaround:
- Re-running the pipeline sometimes succeeds.
- No permanent workaround identified. Disabling shallow clone or submodules may reduce frequency but is not validated.
Prerequisites (if any, like setup, operators/versions):
- OpenShift cluster with Tekton Pipelines installed
- Tekton git-clone task (tektoncd-catalog)
- S2I Go pipeline (s2i-go)
- Base images tested: s2i-go-1.18-ubi7, s2i-go-1.18-ubi9
Steps to Reproduce
- Trigger s2i-go-pipeline-run with Git source https://github.com/chmouel/go-simple-uploader.git
- Use commit SHA: e8e751f5e189ee493a43948b667f665f8d7e1057
- Allow pipeline to reach the Git clone phase
- Observe pipeline logs during git-init execution
Actual results:
The PipelineRun fails with logs showing errors during the Git clone phase. The failure occurs while fetching the repository and results in a fatal exit status.
Logs observed during the failure:
fatal: fsync error on '.git/objects/pack/tmp_pack_YOA5xB': Input/output error
fatal: fetch-pack: invalid index-pack output
exit status 128
fatal: write error: Bad file descriptor
fatal: fetch-pack: invalid index-pack output
exit status 128
The git-init container terminates with:
Error fetching git repository: failed to fetch [<commit-sha>]: exit status 128
Expected results:
- Git repository should clone successfully
- Pipeline should proceed to subsequent build steps without failure
Reproducibility (Always/Intermittent/Only Once):
