What did you do?

This is exactly the same as #65041 with thedifference that this issue concerns the global gitconfig ~/.gitconfig instead of the local .git/config, recreated as #65041 was closed due to the particular decision to ignore the local configuration.

I use a custom core.sshcommand configured at scope/origin global file:/root/.gitconfig, but Go (on docker run golang:1.23-alpine3.20, with apk add git 2.45.2) ignores the command I configured. I have to do GIT_SSH_COMMAND=$(git config core.sshcommand) go mod download to workaround this.

What did you see happen?

/module # go mod download 2>&1 | head -3
go: my.private/[email protected]: reading my.private/repo/go.mod at revision v1.2.3: git ls-remote -q origin in /go/pkg/mod/cache/vcs/xxxxxx: exit status 128:
        Host key verification failed.
        fatal: Could not read from remote repository.

/module # GIT_SSH_COMMAND=$(git config core.sshcommand) go mod download
(successful)

What did you expect to see?

The global gitconfig should be directly read by the Go command instead of separately configuring individual commands.
