It's also responsible for setting hooks in these repositories which will notify the tsuru API when a new deploy is made. For more details check `Gandalf Documentation `_ This document will focus on how to setup a Gandalf installation with the necessary hooks to notify the tsuru API. Adding repositories =================== Let's start adding the repositories for tsuru which contain the Gandalf package. .. highlight:: bash :: sudo apt-get update sudo apt-get install curl python-software-properties sudo apt-add-repository ppa:tsuru/ppa -y sudo apt-get update Installing ========== .. highlight:: bash :: sudo apt-get install gandalf-server A deploy is executed in the ``git push``. In order to get it working, you will need to add a pre-receive hook. tsuru comes with three pre-receive hooks, all of them need further configuration: * s3cmd: uses `Amazon S3 `_ to store and server archives * archive-server: uses tsuru's `archive-server `_ to store and serve archives * swift: uses `Swift `_ to store and server archives (compatible with `Rackspace Cloud Files `_) In this documentation, we will use archive-server, but you can use anything that can store a git archive and serve it via HTTP or FTP. You can install archive- server via apt-get too: .. highlight:: bash :: sudo apt-get install archive-server Then you will need to configure Gandalf, install the pre-receive hook, set the proper environment variables and start Gandalf and the archive-server, please note that you should replace the value ```` with your machine public address: .. highlight:: bash :: sudo mkdir -p /home/git/bare-template/hooks sudo curl https://raw.githubusercontent.com/tsuru/tsuru/master/misc/git-hooks/pre-receive.archive-server -o /home/git/bare-template/hooks/pre-receive sudo chmod +x /home/git/bare-template/hooks/pre-receive sudo chown -R git:git /home/git/bare-template cat | sudo tee -a /home/git/.bash_profile <:3232 ARCHIVE_SERVER_WRITE=http://127.0.0.1:3131 EOF In the ``/etc/gandalf.conf`` file, remove the comment from the line "template: /home/git/bare-template", so it looks like that: .. highlight:: yaml :: git: bare: location: /var/lib/gandalf/repositories template: /home/git/bare-template Then start gandalf and archive-server: .. highlight:: bash :: sudo start gandalf-server sudo start archive-server Token for authentication with tsuru API ======================================= There is one last step in configuring Gandalf. It involves generating an access token so that the hook we created can access the tsuru API. This must be done after installing the tsuru API and it's detailed in the next :ref:`installation step `.
