Running version v3.4.3 with quay.io/argoproj/argoexec:latest or quay.io/argoproj/argoexec:v3.4.3 (both reproduced)

I used same configuration with this issue: https://github.com/argoproj/argo-workflows/issues/7141

Duplicate bug?

[sarabala1979]

@shun095 looks like your argoexec version is wrong. Can you configure the v3.4.3 on your deployment? time="2022-11-26T17:46:33.417Z" level=info msg="Starting Workflow Executor" version=untagged

[shun095]

as my investigation, until v3.3.9 has git binary. Since v3.4.0, it's not included

[jbellow]

I've been doing some testing with argo workflows and have hit this same issue while trying out @descrepes terraform template alongside Terraform Cloud. I dug into it a bit and it looks like the change from using the alpine:3 container to the distroless/static container is where the git binary disappeared. Specifically this commit: https://github.com/argoproj/argo-workflows/commit/bc01003468186ddcb93d1d32e9a49a75046827e7

The updated Dockerfile does copy a couple of additional binaries in (kubectl and jq) but does not grab git as part of the build process. I presume that the git feature has not worked since this change was introduced.

[elia-zakeke]

Any updates on this issue?

I'm using gitArtifact and it worked fine until using git submodules. Now I'm getting this error: time="2023-02-09T18:38:00.383Z" level=info msg="Downloading artifact: argo-source" time="2023-02-09T18:38:05.634Z" level=info msg="Load artifact" artifactName=argo-source duration=5.250753712s error="failed to update submodules: exec: \"git\": executable file not found in $PATH" key=

[Asherslab]

yeah, looks like argoexec container no longer has the git executable past v3.4.0, this is a major issue for git artefacts

[66li]

the same problem

[rohankmr414]

folks, can you try the latest version of argoexec and argo-workflows, we migrated from the git executable to a go native implementation of git https://github.com/go-git/go-git in v3.4.0

[the-newman]

I ran into this issue yesterday when using v3.4.9.

[omarkalloush]

I ran into this issue using v3.5.10

[alexandremahdhaoui]

Hi, I ran in the same issue with v3.5.11. Is there any plans to add git to the binary or revert to alpine?

Alternatively, is there any plans to update the input-artifact-git example: https://github.com/argoproj/argo-workflows/blob/main/examples/input-artifact-git.yaml ?
