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.

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)

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

I'm a Democrat, but I'm really bipartisan - some people might say nonpartisan.

The writers who have the deepest influence on one are those one reads in ones more impressionable, early life, and often it is the more youthful works of those writers that leave the deepest imprint.

Hey, man, I like to look good; I wear make-up.

Not without hope we suffer and we mourn.

Fidelity and allegiance sworn to the King is only such a fidelity and obedience as is due to him by the law of the land; for were that faith and allegiance more than what the law requires, we would swear ourselves slaves and the King absolute; whereas, by the law, we are free men, notwithstanding those oaths.

I grew up in Lambeth, I went to normal schools and I've grown up in a city where people say what they think.

Laughter is a sense of proportion and a power of seeing yourself from the outside.

Attitude with gratitude supported by fortitude will take you to the next altitude

It's a major job to help men and women look beautiful.

From 1949 to 1953, I studied towards the diploma in Natural Sciences at the Swiss Polytechnical School in Zurich. It is in the last year of this study that I made my first contacts with fundamental research, when working on the isolation and characterization of a new isomer of Cl34 with a half-life of 1.5 seconds.

Fundamentalism, as practiced by the Taliban, is the enemy of real thought, and religion too.

I apologize for my terrible interview skills.

I want to be here for a long time, so I am going to do everything I have to do to be here. And I want to walk my daughter down the aisle and give her away to somebody some day. I want to make sure I am still here to make sure my two young sons become men.

Separate educational facilities are inherently unequal.

Dont aim for success if you want it just do what you love and believe in and it will come naturally.

The European nations' loss of sovereignty to the EU should be a warning to Americans.

I like sci-fi.

Im quite sensitive to women. I saw how my sister got treated by boyfriends. I read this thing that said when you are in a relationship with a woman imagine how you would feel if you were her father. Thats been my approach for the most part.

The cemetery of the victims of human cruelty in our century is extended to include yet another vast cemetery, that of the unborn.

I intend to fight and I want to win. But my priorities are basically to be a good Brother and a strong one, and to try to be a good father one day.

I'm a mother of three. I don't really have the time to put very elaborate outfits together, so I keep it casual but dress it up with shoes, a bag, and jewellery.

Dreams are guests who ensoul our lives if we have hospitality for them.

A great nation is any mob of people which produces at least one honest man a century.

Now an audience of more than 1 billion people is only a click away from every voice online, and remarkable stories and content can gain flash audiences as people share via social networks, blogs and e-mail. This radically equalizes the power relationship between, say, a blogger and a multibillion dollar corporation.
