Run a container in background docker run -d Port forwarding with a docker container docker run -p 4000:80 (will map port 4000 of current host to port 80 of docker container)

Container / image An image is like a class, a container is like an instance or object of this class.

Docker Client : can manipulate containers Docker Engine : is installed on a vhost or host to handle containers, it is manipulated by a local or remote Docker Client

Base commands : - docker run xxx (launch image xxx into a new container - dl it from docker hub if not found locally) - docker image ls (list available images on current host) - docker container ls -a (list all containers even not active ones)

Docker Machine ? Deploys and manages vhost/VM on different platforms via its "drivers" : your Mac, Digital Ocean, AWS, a physical server VM are created and deployed with Docker Engine installed, thus you can connect to it with your Docker Client.

Docker Registry : a registry contains multiple repository which contains multiple docker images. You can setup a private registry or use public ones

Service - part of a distributed application like application server or DB server. A service deploys multiple containers in a load balanced subnet

In production you deploy a service with docker swarm and docker stack deploy Make use of a docker-compose.yml file to specify image used and scalability parameters

Stack - other name for a distributed application A stack is managed with docker stack commands

Swarm A docker swarm is a group of machine/host/vhost linked into a cluste Each host into a cluster is called a node

Ex : write a docker compose file Write a docker compose file that will setup two nodejs micro services (server + worker) with their latest image version, allow them to connect, and share with them env var containing a DB connection string. The worker app should be scaled up to 4 services
