- What’s inside?
- What will you get?
- Fully working ansible docker system that’s being setted up within 2-3 minutes.
Before you will start working with this ansible template you need to make sure that you have all of the listed things below:
– A server with Ubuntu 16.04 Xenial installed. 2Gb RAM is recommended minimum for GitLab.
– Ansible 2.3 installed on your local machine.
– Public ssh key to connect to the server.
– Installed and configured Docker. Below you can see a simple command for Docker service setup:
wget -qO- https://get.docker.com/ | sh sudo usermod -aG docker $(whoami)
– Python-minimal installed on the target server. Command to setup:
apt install python-minimal
– Custom SSH port on the server, as port 22 will be exposed outside. Command to configure:
grep port /etc/ssh/sshd_config port 7799 service ssh restart
– DNS records for GitLab and Registry:
host gitlab.thedockerexperts.com gitlab.thedockerexperts.com has address 22.214.171.124 host registry.thedockerexperts.com registry.thedockerexperts.com has address 126.96.36.199
Step 1: Preparation to playbook launch
Before the playbook launch with the ansible role of GitLab setup, we need to prepare the variables and develop the playbook itself. Let’s create directory and necessary files on your local machine:
├── deploy-gitlab.yml ├── host_vars │ └── gitlab.thedockerexperts.com ├── hosts └── requirements.yml
--- hosts: all roles: ansible-docker-gitlab
gitlab_ssh_host: gitlab.thedockerexperts.com registry_host: registry.thedockerexperts.com gitlab_email_from: [email protected] gitlab_email_display_name: GitLab DockerExperts gitlab_email_reply_to: [email protected] time_zone: EET
[all] gitlab.thedockerexperts.com ansible_ssh_host=188.8.131.52 ansible_ssh_port=7799 ansible_ssh_user=root ansible_become=yes
src: git+https://gitlab.itsyndicate.org/public-area/ansible-docker-gitlab.git path: roles
Step 2: Execution of the playbook
To start we need to setup dependencies:
ansible-galaxy install --force -r requirements.yml
After that we can proceed directly to the launch:
ansible-playbook -i hosts deploy-gitlab.yml
Password change is required after that:
We login in GitLab using credentials:
user : root
password: the one you’ve set up before.
Moreover, if you’re curious about how to use Docker you can refer to our guide about top docker commands. It will help you gain confidence in using all the docker commands. Use this article as a how-to guide to practice regularly and docker commands will become second nature to you.
