Auto Deploy after push to git

Question

I have some Codeigniter projects on some domains (on the same server), and the project is already in git.

How to ensure server gets the new update when I push the code to git?

Can anyone explain to me step by step?

Answer 1

You can achieve this using Git and Jenkins job. Create a Jenkins Job to deploy your code to server and Setup Git webhook to Call Jenkins job.

OR

1. Create an empty Git repo on the server

2. Write a Git Hook to deploy the code

3. Deploy from the local computer

Answer 2

Depens on how you hosting your application in production

1. If non docker: use capistrano or other symlink deployment tool
2. If docker: use docker swarm deploy to update your containers
3. Then you need just add .gitlab-ci.yml file to your project directory and write some deployment scripts.

Answer 3

Git itself has a server-side post-receive hook. You can use it to run a command that triggers your deployment whenever you push to your repo. Web services like Gitlab or Bitbucket rely on this mechanism to offer plug-ins that trigger CI services. Less flexible but you can configure it conveniently from the web front end.

Another option would be to use a tool like Puppet on the target machine that periodically checks the repo for changes and pulls them in. The following Puppet code would clone/update the repo into the /path/to/repo directory (by default Puppet runs every 30 min):

vcsrepo { '/path/to/repo':
  ensure   => latest,
  provider => git,
  source   => 'git://example.com/repo.git',
}

See the documentation of the vcsrepo module for details.
