Architecture

Name	Service	Container	Tech
Web	Web	web	React, React-Router
Movies API	Movies	movies	Node, Express
Movies DB	Movies	movies-db	Postgres
Users API	Users	users	Node, Express
Users DB	Users	users-db	Postgres

Setup

1. Fork/Clone this repo

Build and Run the App

Fire up the Containers

Build the images:

$ docker-compose build

Run the containers:

$ docker-compose up -d

Sanity Check

Test out the following services...

(1) Users - http://localhost:3002

Endpoint	HTTP Method	CRUD Method	Result
/users/ping	GET	READ	pong
/users/register	POST	CREATE	add a user
/users/login	POST	CREATE	log in a user
/users/user	GET	READ	get user info

(2) Movies - http://localhost:3004

Endpoint	HTTP Method	CRUD Method	Result
/movies/ping	GET	READ	pong
/movies/user	GET	READ	get all movies by user
/movies	POST	CREATE	add a single movie

(3) Web - http://localhost:4000

Endpoint	HTTP Method	CRUD Method	Result
/	GET	READ	render main page
/login	GET	READ	render login page
/register	GET	READ	render register page
/logout	GET	READ	log a user out
/collection	GET	READ	render collection page

(4) Movies Database and (5) Users Database

If Docker then get the container id from docker ps and then open psql:

$ docker exec -ti <container-id> psql -U postgres

If Kubernetes then get the pod id from kubectl get pods and then open psql:

$ kubectl exec -ti <pod-id> psql -U postgres

Additional Commands

To stop the containers:

$ docker-compose stop

To bring down the containers:

$ docker-compose down

To force a build:

$ docker-compose build --no-cache

To stop all containers:

$ docker container stop $(docker container ls -aq)

To remove all containers:

$ docker container rm $(docker container ls -aq)

To remove all images:

$ docker rmi $(docker images -q)

To recover space:

$ docker system prune --volumes
