Pratice 1 - Install Ansible and Deploy WordPress(docker) using Ansible

Step 1: Install Ansible

Install on Ubuntu

$ sudo apt update
$ sudo apt install software-properties-common
$ sudo apt-add-repository --yes --update ppa:ansible/ansible
$ sudo apt install ansible
Check install Ansible successful

Step 2: Create your own ansible.cfg file on your folder

After create ansible.cfg file, you can run

Step 3: Create your own inventory.ini file on your folder

inventory.ini define hosts, groups you want to manage

my inventory.ini file

[ubuntu1]
192.168.1.127

[ubuntu2]
192.168.1.128

[dvp:vars]
ansible_user=dvp
ansible_ssh_pass=1

[dp:vars]
ansible_user=dp
ansible_ssh_pass=1

Then, you change ansible.cfg file

[defaults]
host_key_checking = False
inventory = /home/Documents/test-ansible/inventory.ini
remote_user = dvp 

Step 4: Test Ansible with your own ansible.cfg file

ping all machine you defined on your own inventory.ini file

Step 5: Install Docker & Docker Compose on group web

---
- name: install docker
  hosts: ubuntu1
  gather_facts: false

  tasks:
  - name: ping
    ping:
    register: result
  - name: install-docker
    become: yes
    apt:
      name: docker.io
      state: present
  - name: install docker-compose
    become: yes
    apt:
      name: docker-compose
      state: present
  - name: ensure docker service is running
    become: yes
    service:
      name: docker
      state: started 

Step 6: Deploy WordPress with Docker-Compose

- name: deploy wordpress
  hosts: ubuntu1
  gather_facts: false

  tasks:
  - name: pull docker compose yaml
    become: yes
    get_url:
     url: https://raw.githubusercontent.com/bitnami/bitnami-docker-wordpress/master/docker-compose.yml
     dest: /home/dvp/docker-compose.yml
  - name: run docker compose
    become: yes
    command: docker-compose up -d
  - name: ensure docker-compose container is running
    become: yes
    docker_container_info:
     name: my_container
    register: result

Step 7: If you wanna check, you can type: sudo docker container ps

and Let's see!

Practice 2: Using Ansible to set up docker on VMs and deploy Wordpress on Ubuntu1, MariaDB on Ubuntu2

Step 1: Create file ansible.cfg, inventory.ini

ansible.cfg (same practice 1)
[defaults]
host_key_checking = False
remote_user = dvp
inventory.ini (define database host)
[ubuntu1]
192.168.1.127

[ubuntu2]
192.168.1.130

[ubuntu1:vars]
ansible_user=dvp
ansible_ssh_pass=1

[ubuntu2:vars]
ansible_user=phuc
ansible_ssh_pass=1

Step 2: Configure and run ansible playbook to install docker on managed machine

Create file install-docker-playbook.yaml

- name: set up docker
  hosts: ubuntu1
  gather_facts: false
  tasks:
    - name: Ping
      ping:
      register: result
    - name: Install docker.io
      become: yes
      apt:
        name: docker.io
        state: present
    - name: Ensure docker service is running
      become: yes
      service:
        name: docker
        state: started

Now, run command:

$ ansible-playbook -i inventory.ini install-docker-playbook.yaml

Step 3:Create your deploy-mariadb-playbook.yaml file on ubuntu1:

- name: deploy mariadb
  hosts: ubuntu1
  gather_facts: false

  tasks:
  - name: create volume for db
    become: yes
    command: docker volume create --name mariadb_data
  - name: deploy mariadb
    become: yes
    command: docker run -d --name mariadb --env ALLOW_EMPTY_PASSWORD=yes --env MARIADB_USER=bn_wordpress --env MARIADB_PASSWORD=bitnami --env MARIADB_DATABASE=bitnami_wordpress --network host --volume mariadb_data:/bitnami/mariadb  bitnami/mariadb:latest   
    register: result2
  - name: setup data
    debug:
     var: result2
  - name: ensure docker-compose container is running
    become: yes
    docker_container_info:
     name: my_container
    register: result
  - name: checking result
    debug:
     var: result

$ ansible-playbook -i inventory.ini deploy-mairiadb-playbook.yaml

Step 4: Configure and run ansible playbook to deploy WordPress on Ubuntu2

Create file deploy-wordpress-playbook.yaml

  hosts: phuc

  gather_facts: false
  tasks:
    - name: Ensure docker service is running
      become: yes
      service:
        name: docker
        state: started
    - name: Create a volume for wordpress
      become: yes
      command: docker volume create --name wordpress_data
    - name: Create the Wordpress container
      become: yes
      command: docker run -d --name wordpress -p 8080:8080 -p 8443:8443 --env ALLOW_EMPTY_PASSWORD=yes --env WORDPRESS_DATABASE_USER=bn_wordpress --env WORDPRESS_DATABASE_PASSWORD=bitnami --env WORDPRESS_DATABASE_NAME=bitnami_wordpress --network host --add-host mariadb:192.168.1.127 --volume wordpress_data:/bitnami/wordpress bitnami/wordpress:latest

Result when we access to Localhost
