Docker is one of the hottest technologies; I started with it's first release not too long back, however, in Docker world it feels like Docker has been around for a long time.
What a paradigm shift we have witnessed: a few technologies get that kind of attention, momentum, growth, and community in such a short time (24 months).
Today, we use Docker to develop, test, ship, integrate, deploy, and run apps/services. Docker has solved developer (devops) usability problems; it's hard to go back and do things without Docker.
Haven't heard of Docker, or didn't find time to try it out? Start with following links.
Compose is a tool for defining and running complex applications with Docker. With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.
Machine makes it really easy to create Docker hosts on your computer, on cloud providers and inside your own datacenter. It creates servers, installs Docker on them, then configures the Docker client to talk to them.
Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual host.Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Flynn, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
As a Docker beginner, I always wondered, how to automatically restart container os or system boot?
Thankfully, Docker 1.2 introduced restart policies (which makes sure even linked containers are started in expected order). The --restart=always flag/value can be passed to ensure automatic restart of containers.
I ended up on YouTube, via hacker-news or somewhere else, to watch a <a href=\"http://www.gresham.ac.uk/lectures-and-events/the-psychology-of-doing-nothing\">lecture</a> which made me realise what I have been going through.
Please watch the following lecture on \"The Psychology of Doing Nothing\" by <span style=\"line-height: normal; -webkit-text-size-adjust: auto; background-color: rgba(255, 255, 255, 0);\">Professor Helga Drummond.</span> You can also read the <a href=\"http://www.gresham.ac.uk/lectures-and-events/the-psychology-of-doing-nothing\">transcript</a> if you don't want to watch whole video.
I recently came to know about Toptal. I am impressed and happy to see that some of the top developers of world are contributing and making difference through Toptal's platform. I want to be among them for only one reason:
I want to work on (and contribute to some of) the best, useful and challenging projects with possibility to collaborate with some of the top/best developers/designers of the world.
NodeSchool is a fully community driven effort and is 100% open source. This means that anyone can use the NodeSchool materials and/or host an event.</p>
I have set up NodeSchool Kanpur chapter, and I hope to organise (with help of like minded people) a couple of workshops on Node.js (and web-development ecosystem around it).
