outline
we can’t talk server development without Docker recently. in here, it’s difficult to explain all details about Docker. we will introduce Docker by explain it little by little when we need. we will explain how to install Docker and Docker Compose on vagrant by Ansible Playbook in this blog post.
this blog is based on the assumption that you have done three blogs below.
set Docker in Ansible Playbook
below is the directory structure for vagrant virtual machine(guest system) we created until now.
|-- ansible
| |-- init
| | |-- tasks
| | | |-- main.yml
| |-- playbook.yml
|-- Vagrantfile
we’ll define role about Docker installation and add Ansible Playbook in here. create docker/tasks/main.yml file in ansible folder.
|-- ansible
| |-- init
| | |-- tasks
| | | |-- main.yml
| |-- docker
| | |-- tasks
| | | |-- main.yml
| |-- playbook.yml
|-- Vagrantfile
modify playbook.yml that is Ansible Playbook’s start point like below.
---
- hosts: localhost
connection: local
roles:
- init
- docker
add below codes to docker/tasks/main.yml we created.
---
- name: Install docker
shell: curl https://get.docker.com | sh
- name: Modify privilege
become: true
shell: usermod -aG docker $USER
- name: Change privilege of docker
become: true
file: dest=/usr/bin/docker mode=+x
- name: python docker / docker-compse module
pip:
name:
- docker
- docker-compose
let’s see Ansible commands one by one.
- name: Install docker
shell: curl https://get.docker.com | sh
this command is to install Docker by using Docker install script.
- name: Modify privilege
become: true
shell: usermod -aG docker $USER
- name: Change privilege of docker
become: true
command: chmod +x /usr/bin/docker
this is to change user and permission of Docker.
- name: python docker / docker-compse module
pip:
name:
- docker
- docker-compose
this command is to install python docker module and Docker Compose
execute Ansible
execute below Ansible command in virtual machine(guest system) to execute Docker installation role we added in Ansible Playbook above.
vagrant ssh
sudo ansible-playbook /vagrant/ansible/playbook.yml
we executed Ansible Playbook because we already have virtual machine(guest system). if we make new environment, Ansible Playbook is automatically executed because we already added provision shell.
execute below vagrant command in local machine(host system) for testing.
vagrant destroy
vagrant up
check Docker is installed
execute below commands to check Docker is installed well on virtual machine(guest system) by Ansible Playbook.
vagrant ssh
docker --version
docker-compose --version
completed
we saw how to install Docker and Docker Compose by Ansible Playbook. now, we can make development environment via Docker. next blog post, we will introduce how to configure Laravel development environment by Docker and Docker Compose.
