inception

This project aims to broaden your knowledge of system administration by using Docker. You will virtualize several Docker images, creating them in your new personal virtual machine.

Rules

make dinstall

Make rule to install doppler (https://www.doppler.com/) CLI to the VM

make dsetup

Make rule to setup doppler project and environment in the VM. We need to have a DOPPLER_TOKEN in this part to set everything correclty. After setting doppler CLI and setting the project we can access the secrets in the terminal with doppler secrets

make denv

Make rule to download all doppler secrets into a .env file in srcs/.env

make drun

Make rule to run all Docker infra with doppler env files injected into docker compose. We do not need to download the env file for this command. Docker images are built if not created, we create our dir for our volumes and we also create our SSL certificates.

make

Make rule to run all Docker infra with .env file and docker compose. We NEED to download the env file for this command. Docker images are built if not created, we create our dir for our volumes and we also create our SSL certificates.

make build

Make rule to build all the Docker images (nginx, mariadb, wordpress 8.2) with docker compose

make down

Make rule to bring the whole infra and containers down with docker compose

make clean

Make rule to clean all the Docker images and docker containers

make fclean

Make rule to to delete all Docker related stuff as make clean but it also deletes volumes, networks and images.

Hacks

• docker ps Check all docker processes running
• docker images List all images created locally
• docker volume ls List all volumes
• docker volume inspect <volume_name> Extra info about volumes
• docker network ls List all networks
• docker exec -it <container_id> sh Jump into runnig container in interactive mode with entrypoint as sh
• docker network inspect <network_id> Shows extra info about the network config (Docker compose manages networking really good)

docker network inspect <inception_network>
