• What’s inside?
  • 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 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 138.68.101.99
host registry.thedockerexperts.com
registry.thedockerexperts.com has address 138.68.101.99

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

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.

WOOHOO! You’re in!
