Here is a very simple way to add automatic deployment via GitHub. This assumes
- You have shell access to your web host
- Your website is in a repository on GitHub
- CGI scripts are enabled for your website
- That git (and optionally composer if you use that) is installed
Log on to your web host and do the initial pull.
$ git clone https://github.com/<you>/<website>.git .
Put the following script in a file named for example
deploy.cgi in your website root.
echo Content-type: text/plain
Add execute rights to the script.
You should now be able to visit
http://<your-website>/deploy.cgi in your browser and see output like this:
Loading composer repositories with package information
Installing dependencies from lock file
Nothing to install or update
Generating autoload files
Set up GitHub service hook
https://github.com/<you>/<website>/settings/hooks, click on WebHook URLs and enter the full URL to your script,
Test it out
With this set up you should be able to make a change at your dev machine, commit it and push it to GitHub. The script should then be executed shortly after and your website should be updated automatically. Pretty cool 🙂
This is of course ultra simple, and if this is a critical site you should probably add some security of some sort. A simple version could be to use a cryptic name like a guid for the script and of course not have this script checked in at GitHub. You might also perhaps want to only pull from a certain branch or things like that, but for a small simple site this works pretty well as long as you remember to only push to GitHub when you have a working set of commits 😉
