git push でリモートのサーバにリポジトリを作成する

流行っているようなので書いてみました。

authorized_keys の設定

.ssh/authorized_keys に command を書いておきます

command="/home/hexa/git.sh" ssh-rsa AAAAB3...

スクリプトは下記の内容です

git.sh

#!/bin/bash

set -- $SSH_ORIGINAL_COMMAND
case $1 in
  git-receive-pack ) REPOSITORY_PATH=$( echo $2 | tr -d "'" )
                     [ ! -e $REPOSITORY_PATH ] && /usr/bin/git --bare init $REPOSITORY_PATH > /dev/null 2>&1
                     /usr/bin/git-shell -c "$SSH_ORIGINAL_COMMAND" ;;
   git-upload-pack ) /usr/bin/git-shell -c "$SSH_ORIGINAL_COMMAND" ;;
                "" ) bash ;;
                 * ) $SSH_ORIGINAL_COMMAND ;;
esac

確認

まだリポジトリが無いリモートのサーバへ、ローカルから git push します

$ ssh hexa@192.168.1.8 'ls bare.git'
Enter passphrase for key '/Users/Hexa/.ssh/id_rsa':
ls: cannot access bare.git: No such file or directory

$ git push ssh://hexa@192.168.1.8:22/home/hexa/bare.git master
Enter passphrase for key '/Users/Hexa/.ssh/id_rsa':

確認のため git clone もしてみます。

$ git clone ssh://hexa@192.168.1.8:22/home/hexa/bare.git
