Tutorial: Continuous integration - The basics
Triggering the hook
You are ready to trigger the hook and see if our first deploy will work.Locally, on your computer, we assume you are in the project folder, where we have the three bash scripts (main.sh, test.sh and deploy.sh). You will have to add, commit and push these files:
chmod a+x *.sh
git add *.sh
git commit -m "First commit"
git push origin main
If the push was done successfully, the hook will be triggered in background.
You can go to Settings / Webhooks and you can check the "Last output"
field to see the last output of the trigger. If the hook did not finished,
the text "n/a" will appear.After some time, you will see the following text:

Tests passed!
Command[./deploy.sh]:
./deploy.sh: line 4: rsync: command not found
./deploy.sh: line 4: rsync: command not found
./deploy.sh: line 4: rsync: command not found
As you can see the tests passed, but we forgot to add rsync to the list of
packages to be installed. Just go to Settings / Webhook / List and
edit your hook: in "Packages to install" text box, add 'rsync' next to 'bash'
and press 'Edit' button.Now, we are ready to push again. Because we changed nothing in the repository, the push will succeed but will not trigger the hook. So, just do a fake change:
echo "Documentation is important" > README
git add README
git commit -m "Added README file"
Now, we will push again:
git push origin main
Now, the "Last output" row will be:

You can see that our 'deploy.sh' script was called, 'rsync' was present
but failed because our server names are fake.That's it! You are now able to setup a test & deploy system to help you with the boring manual procedures.
Next sections will show you some practical examples.
