Ansible - Playground

Enable ssh on targets

To enable ssh on each target:

sudo chmod +x start_ssh.sh
./start_ssh.sh

or

for container in dev prod qa; do

  container_id=$(docker ps -qf "name=$container")

  if [[ -n "$container_id" ]]; then
    echo "✅ Container $container is active, starting ssh service..."
    echo "$container_id"
    docker exec "$container_id" service ssh start
  else
    echo "⚠️ Container $container is shutdown, skipping..."
  fi
done

Troubleshooting

service ssh start

Check if the ssh is enable:

netstat -tlnp | grep :22

Connecting to the master

Run the master shell with the following command:

docker exec -it "$(docker ps -qf "name=master")" /bin/bash

Ping host to quicky see if ansible is able to connect

ansible all -m ping -i inventory.ini

or if vault in configured

ansible all -m ping -i inventory.ini --ask-vault-pass

User & passwords are defined in the .docker/vm.dockerfile, and configured in the ansible/inventory.

If you have success message, it mean you are ready to go ! 🚀

Users configuration

User	Password
root	password
ansible	ansible

Encrypt files with Ansible Vault

Encrypt files with ansible with the following command

ansible-vault encrypt group_vars/<your_file>.vault.yml

By default, for this playground, all files are encrypted with the password password.

Run playbook

Inside the master

Run :

ansible-playbook playbooks/<playbook-name> -i inventory.ini

To run with the vault and vaulted vars

ansible-playbook playbooks/<playbook-name> -i inventory.ini --ask-vault-pass

To run with extra vars

ansible-playbook playbooks/<playbook-name> -i inventory.ini -e <key>=<value>
