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)

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

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 have had so many bad auditions.

I am just relaxing and enjoying myself, doing what I always did.

Skiing not only for yourself and your family, but for your country, was surreal. The amount of support I got from back home in Indiana was insane.

In Mexico, wealth and poverty live next to each other and are cordial with each other - in my experience.

My dream scenario would be that you could go into a bookshop, examine copies of every book in print that they're able to offer, then for a fee have them produce in a minute or two a beautiful finished copy in a dust jacket that you would pay for and take home.

When one door closes, another opens. But we often look so regretfully upon the closed door that we don’t see the one that has opened for us.

Living in a zoo means it wasn't always sparkly dresses, but I would still dress up. I had this pink sparkly dress and fairy wings, and I'd put those on and then go and dance in the zoo.

When I started studying for the arias it was like going into training for a heavyweight title fight.

A lot of the stuff I've accumulated over the last few years of touring I thought was really interesting. Like sounds, sound bites, and beats even, but they weren't good dance beats they weren't ones anyone would want to rap over or anything.

There's no platform for an unsigned music scene in the main cities - it's all hyped acts or showcases behind closed doors. I read about artists that are doing it 'the old-fashioned way' and touring, as if that's a unique thing to do - well, that should just be the way it is.

I feel terribly misunderstood; I feel terribly misunderstood.

Agriculture is the greatest and fundamentally the most important of our industries. The cities are but the branches of the tree of national life, the roots of which go deeply into the land. We all flourish or decline with the farmer.

Every old sock meets an old shoe.

He fertilizes a phrase or a line of poetry for weeks and then gives birth to it in a speech.

A good therapist uses their whole being to engage fully with the whole being of the person coming for help.

Pricey oil makes clear that wealth really is energy in various forms.

I travel a lot to promote the perfumes and to do the commercials.

In a democracy dissent is an act of faith. Like medicine, the test of its value is not in its taste, but in its effects.

A minute’s success pays the failure of years.

Freshman year, I was 95 pounds and 4 feet 10 inches. So you can imagine what my football uniform looked like - my shoulder pads were bigger than my body!

There’s a difference between missing someone and missing having someone.

I loved Nashville. I was amazed by the whole place.

I used to wear disguises, like hats and false beards, just to walk around and avoid attention.

Tis the last rose of summer Left blooming alone; All her lovely companions Are faded and gone.
