What’s inside?
- Automated setup and configuration of Nginx along with SSL certificates from Let’s Encrypt.
- Ansible template for Docker setup and configuration of GitLab.
What will you get?
Fully working ansible docker system that’s being setted up within 2-3 minutes.
Requirements:
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 20.04 installed. 2Gb RAM is recommended minimum for GitLab.
- Ansible 2.9 is 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 138.68.101.99
host registry.thedockerexperts.com
registry.thedockerexperts.com has address 138.68.101.99
Step 1: Preparation for 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 a directory and necessary files on your local machine:
├── deploy-gitlab.yml
├── host_vars
│└── gitlab.thedockerexperts.com
├── hosts
└── requirements.yml
Playbook:
---
hosts: all
roles: ansible-docker-gitlab
Config file:
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
Host file:
[all]
gitlab.thedockerexperts.com ansible_ssh_host=138.68.101.99 ansible_ssh_port=7799 ansible_ssh_user=root ansible_become=yes
Requirements requirements.yml:
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.
