Description 📋

docker_facebook_share

This is a complete stack for running builded Angular App into Docker containers using docker compose tool, with a proxy Nginx between front and back (conected to the DB container with Sequelize ORM).

It is composed by 4 containers:

  • angularfrontend, the one that runs the builded Angular APP in a container with Node and Nginx.
  • nodebackend, a container with node runing and the ORM Sequelize conected to the “postgres” container.
  • middlenginx that handles the request with a proxy configuration, linking front and back.
  • postgres storing the PostgreSQL 14 databases.

Installation ⌨

Docker Installation Illustration

  1. You need Docker and Docker Compose where you are going to launch this so, if you do not have it… click HERE or go to the end of this .md ^^

  2. Clone this rep.

  3. Edit the docker-compose.yml with your DB information. Notice that the configuration for the Postgres database, has information for another user and DB. In the 01-init.sh file, that is in db dir, there is a configuration for adding the password postgres to the postgres user and creating a new DB, called docker with a new user with the same name and password. Change if you need to. Apart from this, modifies the ph_hba.conf adding host all all 0.0.0.0/0 md5 so there is no problems with the conection of the database and the users.

  4. Run docker compose up to check that everything runs correctly. If there it no errors, stop (ctrl+C) and delete containers with docker compose down. Now you can run it with docker compose up -d. This will run it in the background.

  5. To check that eveything is running correctly in the background, run docker compose ps -a and you will see the running containers.

Docker’s useful commands 📑

Docker Commands Illustration

  • Run Docker Compose: docker compose up -d / docker compose up

  • Check Docker Compose’s volumens status: docker compose ps -a / docker compose ps

  • Check Docker’s images: docker images -a

  • Remove Docker’s images: docker rmi -f imageID1 imageID2 ... (-f = force)

  • Enter to a Docker’s volumen: docker compose exec VolumenID sh / docker compose exec VolumenID bash

  • Copy a file to the docker we want to: docker cp file docker_id:/dir

  • Remove all dangling (not tagged or associated with a container) containers, volumes, networks and images: docker system prune

  • Remove all unused containers and images with at least one container associated to them: docker system prune -a

  • Shows all unused local images: docker images ls -f dangling=true

  • Shows all unused local volumes: docker volume ls -f dangling=true

  • Remove all local volumes not used by at least one container: docker volume prune

Installing Docker and Docker Compose 🛠

Docker Composer

Adjust the installation to your OS. Here you have the one for Linux Mint (Ubuntu based)

Docker installation

  1. Download and install Docker: apt install docker

  2. Gives permisions so you can run it everywhere: sudo usermod -aG docker $USER

  3. Starts Docker’s service: service docker start

  4. Starts Docker’s service each time you run the SO: chkconfig docker on

Docker Compose V2 installation

For this repo, DockerComposeV2 was used, so that is why we use docker compose instead of docker-compose. If you are using DockerComposeV1, have this in mind.

  1. Run sudo apt-get install docker-compose-plugin

  2. Check which versions are availables with apt-cache madison docker-compose-plugin

  3. Intall the version you are looking for with sudo apt-get install docker-compose-plugin=<VERSION_STRING>, for this repo sudo apt install docker-compose-plugin=2.6.0~ubuntu-focal was used.

  4. Check the version and the installation: docker compose version
