WebApp Server

The setup scripts to create development environments for many groups.

Requirements

• Docker >1.13
• Python 3 (pip & venv)
• libyaml-dev

Setup

Students

The configuration is done via a TSV file (config/students.tsv). Here is its format:

Lastname	Firstname	Email	Group	Github	Image1	Team1	Image2	Team2	Comment
Bon	Jean	jean.bon@example.org	INF3	jeanjean	Laravel	ninjas	Rails	funky	-
Blanc	Yoan	yoan.blanc@he-arc.ch	Teacher	greut	Laravel	admin	Python	admin	-

This is how this file is used:

• Lastname no particular usage
• Firstname becomes the username
• Email no particular usage
• Group no particular usage
• Github identifier to download the SSH public keys
• ImageX stores the information of which container to use
• TeamX will be the name of the virtual host and identify a container
• Comment no particular usage

Setup

The scripts require docker-compose as well as other dependencies.

$ python3 -m venv .
$ . bin/activate
(webapp-server)$ pip3 install -r requirements.txt

Docker-compose

Based on the TSV file, you can generate a Docker Compose YAML file.

$ scripts/make_compose.py eatapp \
    < students.tsv \
    > teams/eatapp-compose.yml

Then adapt the port number, and run it.

$ docker-compose -f teams/eatapp-compose.yml up

Database creation

Reusing the docker-compose.yml file, we create the databases.

$ scripts/bdd.py < teams/eatapp-compose.yml

Containers

If you don't want to use the publicly available containers, you can build them yourself.

# Base container
$ make base
# Laravel container
$ make laravel
# Python container
$ make python
# Rails container
$ make rails

Run via docker-compose

Create a docker-compose.yml file base on the sample one.

Run the container(s)

# create the shared network
$ docker network create --driver=bridge webapp-net

# running the central services
$ docker-compose up -d

# running "a" project
$ docker-compose -f examples/base.yml up -d

• Traefik control dashboard runs on port 8080.
• Portainer control dashboard runs on port 9000. The admin password must be set upon boot!

Databases

The databases are open the external world, hence we must modify the super admin password. Setting up a good one during the startup won't be as effective as it will be visible from within the containers anyway.

MySQL

Change the password either in the docker-compose.yml file or afterwards this way.

$ mysql -h 127.0.0.1 -u root -proot
> SET PASSWORD FOR 'root'@'%' = PASSWORD('s3cur3@P45sw0rd');

PostgreSQL

Change the password either in the docker-compose.yml file or afterwards this way.

$ psql -h 127.0.0.1 \
    -U postgres \
    -c "ALTER USER postgres WITH PASSWORD 's3cur3@P45sw0rd';"

Standalone setup

Below is a sample of a simple PHP machine with a MySQL instance. The default environment variable can be overridden (see scripts/boot.sh)

version: "3"

services:
  web:
    image: hearcch/webapp-server:laravel
    ports:
      - "8080:80"
      - "2222:22"
    environment:
      - GROUPNAME=test
      - PASSWORD=test
      - SSH_KEYS=greut
    volumes:
      - web:/var/www
    depends_on:
      - mysql

  mysql:
    image: mysql:5.7
    ports:
      - "3306:3306"
    environment:
      - MYSQL_DATABASE=test
      - MYSQL_USER=test
      - MYSQL_PASSWORD=test
      - MYSQL_RANDOM_ROOT_PASSWORD=1
    volumes:
      - mysql:/var/lib/mysql

volumes:
  web:
  mysql:

The login using your github SSH key.

$ ssh -p 2222 poweruser@127.0.0.1

Volumes and Windows

On non-UNIX filesystem, it's okay to mount a local folder a the /var/www volume. However, on Windows, don't do it and mount the container volume on the machine using SFTP(e.g. http://www.sftpnetdrive.com/)
