Getting Started With Ansible
Here is a tutorial of how I would start a server from scratch using ansible and docker
In my previous article I showed how to install a “root” server onto a Virtualbox. The following tutorial should work for both 18.04 and 20.04 all ubuntu flavors as long as you have root access.
This is how you install Ansible on Ubuntu:
# Skip this step if you are running 20.04
# if you are running 18.04 you need this step:
# 20.04 is running version 2.9.6 at the time of writing
sudo apt-add-repository --yes --update ppa:ansible/ansible
# run this to install ansible
sudo apt install -y ansible
# if you are running xubuntu run this:
sudo apt install -y sshpass
Note: try this if you are having problems or using a slightly different flavor or older version of Ubuntu:
sudo apt install software-properties-common
Then re-run apt install Ansible.
Next I have my initial run playbook saved to my public Github account so I can just download and run it:
wget https://fbot.co/playbook -O firstplaybook.yml
ansible-playbook -i localhost, -u root -k firstplaybook.yml
Here is the Ansible playbook file that I download.
Note: In the playbook I’ve added my user to the docker group so I can run it not as root or using sudo.
-i option is for hosts list (it’s an array so make sure you have a comma) -u is user to use -k is to ask for password
That’s it, you have Ansible installed and you have docker installed, next let’s get git up and running.
Known Issues
If you receive the error:
fatal: [localhost]: FAILED! => {"msg": "Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host."}
It means you have not logged into the server before and you need to add the server’s fingerprint to your known_hosts. Just login manually first:
ssh root@localhost
