This is useful if you want to deploy automate deployment and run running of MDPM on a new dedicated machine, such as an EC2 instance.
...
remote environments. In this example, I'll be controlling a remote machine called 'albatross', a Raspberry Pi with username 'pi'. I'll be building a driver and running it doing all the parameterisations through Ansible.
Setting up inventory
Create a file called hosts and put in it the IP address of the remote machine:
| Code Block | ||
|---|---|---|
| ||
[albatross]
192.168.1.108 # the IP address of the remote machine |
When you have created a playbook, you have to specify using this hosts file by running ansible-playbook -i hosts playbook.yaml.
Setting up connection credentials
On the remote system, add your SSH public key to ~/.ssh/authorized_keys.
Tasks for the workhorse role
Create a file at workhorse/tasks/main.yml (relative to your base directory) and put the following in it.:
