Once Petals ESB is installed through the Debian package, it can be started or stopped with two different ways:

Starting Petals ESB
Starting Petals ESB at system level
Automatic start
The Petals ESB package comes with an automatic startup script based on System V (initd) to automatically launch Petals ESB containers as system services when the host boots.
To start the Petals containers, for example, launch the following command on a Ubuntu box:
cdeneux@sph-latitude-D630:~$ sudo service petals start
Two natures of containers are identified:
- the "available containers" that are configured. These containers are to configure into the directory /etc/petals-esb/container-available. One sub-directory by container.
- and, the "enable containers" that are automatically started. These containers are to configure into the directory /etc/petals-esb/container-enable. One sub-directory by container.
As "Enable containers" are a subset of "Available containers", we recommend to put the configuration of a container into a sub-directory of /etc/petals-esb/container-available, and create a symbolic link on this sub-directory into /etc/petals-esb/container-enable to "enable" it.
 | It's not possible to automatically start a container in debug mode. Use a manual startup. |
 | Caution: The automatic startup starts all Petals ESB containers declared in the directory /etc/petals-esb/container-enable. So if you add a new Petals ESB container in the sirectory, and use the command "service petals-esb start", all other Petals ESB containers will be also started, and as they are already started, errors will occurs. |
