+## Pebble supervisor
+
+A supervisor is a parent processus that manages one or several processes. It controls the lifecycle of a process thanks to a configuration so that your process is ensured to be running as long as needed.
+
+### Docker/K8S
+
+We already provided the well-known S6 supervisor which is activated by default in our Docker image. It is enabled by the command line option `--with-s6-overlay`.  We propose now an other awarded supervisor: Pebble. You can find documentation about Pebble in Canonical [documentation](https://github.com/canonical/pebble). The Ingress Controller can switch to Pebble by the flag `--with-pebble`. Note that the official Docker images are stil using S6 but you can build your own with Pebble thanks to the provided Dockerfile `Dockerfile.pebble`. To build your own Docker image supervised by Pebble simply run `make build-pebble`. Here you go, just upload the Docker image in the according registry if necessary and that's it. Your new controller will automatically use Pebble for its process management.
+
+### External mode
+
+Please install pebble in a location included in your PATH environment variable (check documentation for installation).
+You need to create your own Pebble directory if you don't want to use the default directory. In the following presentation, we'll keep the default one.
+In `/var/lib/pebble/default/` copy the run-controller and run-haproxy scripts and adapt the executables paths according your environment. These scripts are located under `fs/var/lib/pebble/default/` in the git repository. Then add the `layers` directory in `/var/lib/pebble/default/` and copy in it the file `fs/var/lib/pebble/default/layers/001-haproxy.yaml`. If you didn't change the default directory of Pebble you don't need to change anything. Now you start with `pebble run`.
