Este repositório tem a finalidade de demonstrar como subir um ambiente do Gitlab-CE e GitlabCi utilizando Docker e Aws Spot para provisionamento de infraestrutura.

Fork from: github.com/nascimento/gitlab_gitlabci_docker_aws

This repo was based on Gitlab Documentation: https://docs.gitlab.com/runner/configuration/runner_autoscale_aws/

Project Structure

Terraform

Modules

• terraform_global

  This folder has scripts that creates AWS base infra-structure to Gitlab Server and Runner.

  • vpc
  • subnet
  • security_group (publico)
  • key_pair

• terraform_gitlab

  This folder has scripts that creates the infra-structure on AWS with Gitlab.

  Important: The Gitlab Server instaled here has no backup, so do not use this in production.

  Creates:

  • ec2

• terraform_gitlab-runner

  This folder has scripts that creates the infra-structure on AWS with GItlab-Runner with automatic registering runner on Gitlab Server.

  Creates:

  • Ec2 Spot (t2.small)
  • Ec2 Spot with Docker.
    • Gitlab-Runner automatic creates Docker Servers based on gitlab/config.toml and automaticaly scale it with Docker+Machine.

  Documentation: https://docs.gitlab.com/runner/configuration/runner_autoscale_aws/

How to run:

First, configure your AWS_SECRETS* on ~/.aws/credentials after terraform run.

Doc: https://docs.aws.amazon.com/pt_br/cli/latest/userguide/cli-chap-getting-started.html

Before, run terraform:

terraform plan 
terraform apply 

Running terraform we will:

• Configure based infraestructure on AWS
• Create an Ec2 instance for Gitlab App
• Create an Ec2 Spot request to run Gitlab-Runner (This use user-data shell script).

How to test

• Access Gitlab Server with public DNS or IP.
• Push the projeto _project_high_cpu inside this projeto to created gitlab and push changes some times to see the magic happening.
