Dear Customer, the RevolutionPi Revolution Pi is based on an open source platform, which can lead to misbehavior of the devices. To solve some problems, you can use Ansible. Because Ansible is all about automation, it requires instructions to accomplish each job. With everything written down in simple script form, it's easy to do version control and automate repetitive tasks with relative ease. Regardless of whether it is a single system or many. It is available as open source software under the GNU General Public License for DevOps around the world.

- Automatic copying of the public key to the target system
Ansible automates important tasks on a target system via SSH. The SSH key of the Ansible host is located on the target system. With ssh-keygen, an SSH key is generated for your target system and entered into a repository. The repository is always different.

After we have created an SSH key, we can enter it manually in the authorised_keys file of the remote computer or use the ssh-copy-id command. We will use the ssh-copy-id command to simplify this process. Simply call the ssh-copy-id command and pass the path to the public key as follows:

# Copying the SSH key with SSH-copy-id for the system of our example
ssh-copy-id -i /root/.ssh/id_rsa.pub pi@192.168.0.66 |
- Cloning the repository
We have a repository on Github where all the essential elements for solving the tasks are stored. This repository can be reached through this link https://github.com/RevolutionPi/revpi-ansible-recipes.
...
With the command ls -l, you can see all contents of the order revpi-ansible-recipes
...
- A An "Inventory" must be created. In the inventory, you must enter the IP address of your target system. All devices on which the tasks are to be executed must be entered under [bet] as shown below (see the picture inventory adjustment)
...
Now get back to the last order revpi-ansible-recipes and editing the new ansible-script (myplaybook.yml) to , that perform the task for the role network-bridge.

Once the script has been successfully executed, we can see the status of the execution, as shown in the following illustration:
