It works fine if coupled with URL replacement. The custom hostname will be replaced transparantly for you and won't need to make it into gitmodules. # ~/.

It works fine if coupled with URL replacement. The custom hostname will be replaced transparantly for you and won't need to make it into gitmodules. # ~/.config/git/config # Only for single user/org [url "git@github_ssh:foo"] insteadOf = "git@github.com:foo" # all the things [url "git@github_ssh"] insteadOf = "git@github.com" Similar pattern if you want to force-use ssh instead of https or vice-versa.
