[Feature]: ability to configure git specifically for container-use

[danielparks]

What feature would you like?

It would be nice to be able to set git configuration — either a configuration file like .gitconfig, or command line options — that only applies to container-use.

For example, I want to sign all of my commits with the signing key specified in the repo configuration, but I don’t want container-use to sign my commits at all.

Why would this be useful?

It makes it possible to do things like set the commit author to “Claude”, or disable commit signing for LLM-produced commits.

I would also love this feature. My workaround for now is adding some env vars to the environment:

$ container-use config env list
1. GIT_CONFIG_KEY_0=commit.gpgsign
2. GIT_CONFIG_VALUE_0=false
3. GIT_CONFIG_COUNT=1

…but that seems clunky, and starts to get unwieldy when I need to specify/override more options.
