Create repo on git push fails with error

Question

I followed the steps where I prefixed the authorized key with a run to a ruby script that creates the repo. The script successfully creates a repo, but the git-receive-pack sending of code fails to unload properly. the repo is owned by the same user doing the push.

fatal: ''/path/to/my/repo'' does not appear to be a git repository

Also as another symptom my ssh session automatically closes with a command prefix in place. As soon as I remove the command, it pushes without issue.

For our build system this would be a nice feature to have, so looking for any insight on the behavior.

script for example

require 'git' require 'fileutils' require 'mixlib/shellout' var = ENV['SSH_ORIGINAL_COMMAND'] def process_request(var) path = var.split[1].gsub("'", '') unless File.exist?(path) FileUtils.mkdir_p(File.dirname(path)) Git.init(path, bare: true) end command = Mixlib::ShellOut.new(var) command.run_command end process_request(var) if var.to_s.include?('git-receive-pack')

My issues lied with how i was calling a shell to resume normal operation. modified the script from original post to better meet my needs.

require 'fileutils' require 'logger' require 'git' LOG = Logger.new('/path/to/gitlog/create_on_push.log') SSH_COMMAND = ENV['SSH_ORIGINAL_COMMAND'] USER_SHELL = '/bin/sh' PATH_PREFIX = '/path/to/gitdir' ######################################################################### # create missing path and repo # # @param path [string] path to the repository to create # def initialize_repo(repo_path) path = File.join(PATH_PREFIX,repo_path) unless File.exist?(path) LOG.info("initializing repository #{path}") FileUtils.mkdir_p(File.dirname(path)) Git.init(path, bare: true) end end ######################################################################### # run ssh command if no arguments # def noargs LOG.info('running shell with no arguments') exec USER_SHELL end ######################################################################### # run supplied ssh command # def shell_with_command LOG.info("shell with command \"#{SSH_COMMAND}\"") exec USER_SHELL, '-c', SSH_COMMAND end ######################################################################### # initialize repo and allow for push of content to repo # # @param command [string] command to run # @param path [string] path to the git repo # def git_shell_args(command, path) repo_path = path.gsub('\'','') initialize_repo(repo_path) exec 'git-shell', '-c', "#{command} '#{repo_path}'" end # default action if no ssh commands were supplied noargs if SSH_COMMAND.nil? # words is empty or have 2 words command, path = SSH_COMMAND.split(' ') case command when 'git-receive-pack' git_shell_args(command, path) when 'git-upload-pack' git_shell_args(command, path) else shell_with_command end
