About

This is a collection of my ansible resources

Installation

Installing ansible with virtualenv and pip:

python3 -m pip virtualenv -p python3 .venv
source .venv/bin/activate
pip install ansible==4.4.0

Configuration

Our main ansible configuration defined in a ansible.cfg, as example:

[defaults]
inventory = inventory

Your servers will be defined in a inventory file which we will name inventory, which can look something like this (as an example):

[local]
my.laptop  ansible_connection=local

[webservers]
10.0.2.10  ansible_host=10.0.2.10
10.0.2.11  ansible_host=10.0.2.11

[local:vars]
deprecation_warnings = False

More info on inventory can be found here:

Verifying Connectivity

Change to the local directory:

$ cd local

Let's review our inventory file:

[localhost]
my.laptop       ansible_connection=local
my.workstation  ansible_connection=local

Which you can see is using the local ansible_connection. You get a ssh and local connection, and for the demonstration we will be using the local connection as a starting point.

Now we can use the ping module, to ensure that ansible can reach our localhost group or my.laptop target.

To target the host only:

$ ansible -i inventory my.laptop -m ping
my.laptop | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

To target the group (this is useful when theres more than one target in a group:

$ ansible -i inventory localhost -m ping
my.workstation | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
my.laptop | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

Because we defined inventory = inventory under our [defaults] section in our ansible.cfg, we can remove the inventory argument, which results in:

$ ansible localhost -m ping

Provisioning Servers

We can use multipass to provision ubuntu vms, to follow the example for multipass, head over to extras/multipass
