postCreateCommand deletes git config

[luftuq]

Hi all,
I see inconsistent result when I run
"postCreateCommand": "git config --global user.signingkey /home/mambauser/.ssh/id_ed25519.pub"
to redirect my keys to docker folder. All other global configurations (which are moved to docker automatically) are not in container. This does not happen if I change it to postStartCommand. I would expect that result would be the same. Simplified devcontainer.json where it happens is here:

  {
    "name": "name",
    "build":{
        "dockerfile": "Dockerfile",
        "context": "../",
        "args": { "HTTP_PROXY": "${localEnv:HTTP_PROXY}",
                  "HTTPS_PROXY": "${localEnv:HTTPS_PROXY}" 
                }
    },
    "containerEnv": { "HTTP_PROXY": "${localEnv:HTTP_PROXY}",
                   "HTTPS_PROXY": "${localEnv:HTTPS_PROXY}" 
    },
  "mounts": [
    "source=${localEnv:USERPROFILE}/.ssh,target=/home/mambauser/.ssh,type=bind,consistency=cached"
    ],
    "postCreateCommand": "git config --global user.signingkey /home/mambauser/.ssh/id_ed25519.pub"
}

and the dockerfile:

    FROM mambaorg/micromamba
    ARG MAMBA_DOCKERFILE_ACTIVATE=1 
    RUN micromamba config append channels conda-forge
    # Install Git
    USER root
    RUN apt-get update && apt-get install -y git
    USER $MAMBA_USER

Hi @gauravsaini04,
I am sorry it took me a while. Here is really minimal reproduction I can do.
devcontainer.json:

{
"name": "name",
"build":{
    "dockerfile": "Dockerfile",
    "context": "../"
    //"args": { "HTTP_PROXY": "${localEnv:HTTP_PROXY}",
    //          "HTTPS_PROXY": "${localEnv:HTTPS_PROXY}" 
    //        }
},
"postCreateCommand": "git config --global user.name test"
}

Dockerfile:

FROM mambaorg/micromamba
USER root
RUN apt-get update && apt-get install -y git
USER $MAMBA_USER

The issue is, that if I switch postCreateCommand for postStartCommand, I will get different results after rebuild.

Hello @luftuq ,

Thank you for your patience and for providing simpler steps to reproduce the issue. I have one final request in this regard. You have mentioned in the issue description that certain global configurations which had moved automatically to the docker container were retained while using the postStartCommand tag.
Would you kindly point them out for my better understanding of the issue?

With Regards,
Kaniska
