I have created a bounty on Stackoverflow for an answer to this question.
Is there any way to set different SSH keys to ruby-git configuration on the fly, so I can work with different private repos?
What I've done is working well, but it works with one SSH key only.
I have created /ruby_git.sh in the root folder of my Rails app:
#!/bin/bash
exec /usr/bin/ssh -o StrictHostKeyChecking=no -i ./certs/private_key "$@"
I have created /certs/private_key with my SSH key:
-----BEGIN OPENSSH PRIVATE KEY-----
...
-----END OPENSSH PRIVATE KEY-----
I have created /initializers/git_init.rb:
Git.configure do |config|
config.git_ssh = Rails.root.join("ruby_git.sh").to_s
endI have also tried another approach, to create custom sh scripts and SSH private key files for each repo in runtime and delete them after use. But this seems to alter Git globally, so the next thread/session inherits the new Git config:
# @repo_id, @ssh_url and @private_key are instance variables set
# based on the repo that we try to interact with
cert_path = Rails.root.join("git_config", "certs", @repo_id).to_s
config_path = Rails.root.join("git_config", "configs", "#{@repo_id}.sh").to_s
git_config = "#!\/bin\/bash\n\nexec \/usr\/bin\/ssh -o StrictHostKeyChecking=no -i #{cert_path} \"$@\""
File.open(config_path, "w") { |f|
f.write(git_config)
}
File.open(cert_path, "w") { |f|
f.write(@private_key)
}
File.chmod(0755, config_path)
File.chmod(0600, cert_path)
Git.init
Git.configure { |config|
config.git_ssh = config_path
}
Git.ls_remote(@ssh_url)
FileUtils.remove_entry(cert_path)
FileUtils.remove_entry(config_path)Your environment
