Gitlab HA setup template on AWS
===============================
This template is a POC to setup a [Gitlab](https://about.gitlab.com/) system with [High Availability](https://about.gitlab.com/high-availability/) on [Amazon Web Service Cloud](https://aws.amazon.com/).
This template is heavily inspired by [Gitlab university : HA on AWS](https://docs.gitlab.com/ce/university/high-availability/aws/).
The project tries to follow Immutable server pattern and Infrastructure-as-Code principles by using :
* [Packer](https://www.packer.io/) to create [Amazon Virtual Machine Images (AMI)](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AMIs.html)
* [Ansible](https://www.ansible.com/) to install and configure packages on these Virtual Machine Images when running Packer
* [Terraform](https://www.terraform.io/) to create and orchestrate the cloud infrastructure
* [cloud-init](https://cloudinit.readthedocs.io/en/latest/) and [jinja2-cli](https://github.com/mattrobenolt/jinja2-cli) to finalize setup automatically when launching AWS instances from AMI
* [Docker](https://www.docker.com/) to run Continuous Integration in containers with [Gitlab-CI](https://about.gitlab.com/gitlab-ci/)
Requirements
------------
* a [AWS account](https://aws.amazon.com/) (**Be careful this template implies creating billable resources on AWS cloud**)
You will need an [AWS access key](http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html) and enough admin permissions to create AWS ressources
* a [AWS Route 53 DNS zone](http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/Welcome.html) already created (the template will add new subdomain DNS A records)
* a SSH Key pair to connect to Gitlab and AWS instances (see [Github help for examples](https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/))
* [Packer](https://www.packer.io/) >= 0.12
* [Terraform](https://www.terraform.io/) >= 8.2
* GNU Make or some Unix equivalent Implementation
* *(optional)* [Graphiz](http://www.graphviz.org/) to generate Terraform config Graph Images
```sh
# on ubuntu/debian
sudo apt-get install graphviz
```
Usage
-----
### Download the terraform and packer templates
```sh
git clone --recursive https://github.com/csanquer/gitlab-setup.git
```
### To create the Gitlab infrastructure
1. Copy and edit the configuration files :
* **terraform** : `terraform/terraform.dist.tfvars` to `terraform/terraform.tfvars`
* **packer** : `packer/config.dist.json` to `packer/config.json`
2. create Amazon Machine Images :
* Gitlab
* Gitlab-CI-multirunner
```sh
make ami
```
3. check Terraform plan
```sh
make plan
```
3. if terraform plan is correct, create AWS resources by applying the terraform plan
```sh
make apply
```
* you can check again the terraform exported variables output
```sh
make output
```
* you can also get Graphviz graphs of all terraform config
```sh
# in PNG image format
make graphs
# or in SVG
make graphs format=svg
```
After creation, wait for a few minutes the autoscaled gitlab instances finish self initialization.
if variables are set in `terraform/terraform.tvars` like :
```hcl
aws_dns_zone = "my-aws.net"
gitlab_dns_subdomain = "gitlab"
```
The Gitlab server should be available to http://gitlab.my-aws.net/
### To destroy the Gitlab infrastructure
```sh
make destroy
```
