Naramsim / docker-mysql-prom

docker-mysql-prom

This project is just a coding challenge I was asked to do.

• Create a Linux server with Docker installed
• Deploy a MySql DB on Docker
• Deploy a Prom that monitors the DB on Docker
• Deploy a Docker service that reads/writes the DB
• Expose Prom to the Internet

Architecture

Please look at the code

Config

There is currently no IaaS code so you have to create on GCP a CentOS machine with a disk-1 disk attached. Then change the fixed IP you find in the hosts.yml.

Before running ansible you should make a copy of the compose/.env.sample and change the password written in there.

cp .env.sample .env
nano .env

You should also change the user and public_key in ansible/roles/identities/.

Init

cd ansible
ansible-playbook -e 'ansible_user=<user_of_public_key>' -i hosts.yml init.yml

This will create the user ansible on the machine which will be then used by ansible.

To run ansible:

ansible-playbook -i hosts.yml playbook.yml

Run

I decided not to start the docker containers with Ansible, so you have to login into the instance and:

bash /opt/application/scripts/bootstrap.sh

Open <http://instanceIP/graph>
