Multi Service Docker Containers

Prerequisites:

• Install Docker Desktop: https://www.docker.com/products/docker-desktop

Quick Start:

After cloning the repo follow these steps.

1. Edit Hosts file:

sudo vim /etc/hosts

2. Add this to the end of your /etc/hosts file:

127.0.0.1               alison.test
127.0.0.1        db-api.alison.test
127.0.0.1        db-etl.alison.test
127.0.0.1       web-app.alison.test
127.0.0.1       web-cms.alison.test
127.0.0.1       web-etl.alison.test
127.0.0.1    server-api.alison.test
127.0.0.1    server-etl.alison.test
127.0.0.1    server-gql.alison.test
127.0.0.1 server-strapi.alison.test

3. Type ESC:wq to save and quit vim.
4. In a Terminal window cd to the directory with the docker-compose.yml file.
5. Run the docker-compose command to build the images and start the containers. The strapi container takes a few minutes to start for the first time.

docker-compose up

6. Once all the docker containers have started try visiting:

   • http://alison.test noting to see
   • http://web-app.alison.test
   • http://web-cms.alison.test
   • http://web-etl.alison.test
   • http://server-api.alison.test
   • http://server-etl.alison.test
   • http://server-gql.alison.test
   • http://server-strapi.alison.test

7. Connect to MySQL Containers If desired:

db-api (used by strapi)

host: alison.test
port: 4400
username: api
password: api
database: api

db-etl (example db running in parallel)

host: alison.test
port: 4401
username: etl
password: etl
database: etl

8. Stop the containers

docker-compose stop

9. When making container or image changes you can run this command to rebuild and start.

docker-compose --force-recreate --always-recreate-deps --build

Docker Compose

Build based on docker-compose file and don't use cached images.

docker-compose build --no-cache

Start and make sure everything is blown away and recreated from the ground up.

docker-compose up --force-recreate --always-recreate-deps --build

Create a named network dns hostnames to be resolved.

docker network create alison-net

server-api

cd ./server-api

Build the Image from the Dockerfile:

docker build . \
    --no-cache \
    --label server-api \
    --tag trozdol/server-api

Run the container based on the above image:

docker run \
    --rm \
    --detach \
    --env NODE_ENV=dev \
    --env PORT=80 \
    --publish 8000:80 \
    --network alison-net \
    --name server-api \
    --hostname server-api \
    trozdol/server-api

server-etl

cd ./server-etl

Build the Image from the Dockerfile:

docker build . \
    --no-cache \
    --label server-etl \
    --tag trozdol/server-etl

Run the container based on the above image:

docker run \
    --rm \
    --detach \
    --env NODE_ENV=dev \
    --env PORT=80 \
    --publish 8001:80 \
    --network alison-net \
    --name server-etl \
    --hostname server-etl \
    trozdol/server-etl

server-gql

cd ./server-gql

Build the Image from the Dockerfile:

docker build . \
    --no-cache \
    --label server-gql \
    --tag trozdol/server-gql

Run the container based on the above image:

docker run \
    --rm \
    --detach \
    --env NODE_ENV=dev \
    --env PORT=80 \
    --publish 8002:80 \
    --network alison-net \
    --name server-gql \
    --hostname server-gql \
    trozdol/server-gql

Nginx

docker build . \
    --no-cache \
    --label web-app \
    --tag trozdol/web-app

docker run \
    --rm \
    --env ENV=dev \
    --publish 8081:80 \
    --network alison-net \
    --name web-app \
    --hostname web-app \
    trozdol/web-app

MySQL

db-api (wip)

docker build
    --no-cache \
    --label db-api \
    --name db-api \
    --mount type=bind,src=./db-api/my.cnf,dst=/etc/my.cnf \
    --mount type=bind,src=./db-api/data,dst=/var/lib/mysql \
    -d mysql/mysql-server

docker run \
    --rm \
    --detach \
    --network alison-net \
    --publish 3306:3306 \
    --hostname db-api \
    --name=db-api \
    mysql/mysql-server

db-etl (wip)

docker build
    --no-cache \
    --label db-etl \
    --name db-etl \
    --mount type=bind,src=./db-etl/my.cnf,dst=/etc/my.cnf \
    --mount type=bind,src=./db-etl/data,dst=/var/lib/mysql \
    -d mysql/mysql-server

docker run \
    --rm \
    --detach \
    --network alison-net \
    --publish 3306:3306 \
    --hostname db-etl \
    --name=db-etl \
    mysql/mysql-server
