Database products:

docker run --name product-db -p 5433:5432 -e POSTGRES_DB=product-db -e POSTGRES_USER=admin -e POSTGRES_PASSWORD=123456 postgres:11

Stopping container:

docker container stop <nome do container, ex: auth-db>

Visualize containers:

docker ps

docker container inspect <container> 

Remove all containers:

docker container prune

Visualize volumes:

docker volume ls

Remove volume:

docker volume rm <volume>

"startingDirectory": "%SystemDrive%/code/"

Running image mongo-express on docker:

docker run --name sales-db -p 27017:27017 -p 28017:28017 -e MONGODB_USER="admin" -e MONGODB_DATABASE="sales" -e MONGODB_PASS="123456" tutum/mongodb

MongoDB url connection:

mongo "mongodb://admin:123456@localhost:27017/sales"
