# Welcome to Docker Labs

![My image](https://github.com/collabnix/dockerlabs/blob/master/images/dockerlabs.jpeg)

Are you new to Docker? Want to build your career in Container Technology?

Then Welcome ! You are at the right place.

DockerLabs brings you tutorials that help you get hands-on experience using Docker & Kubernetes. Here you will find complete documentation of labs and tutorials that will help you, no matter if you are a beginner, SysAdmin, IT Pro or Developer. Yes, you read it right ! Its $0 learning platform. You don't need any infrastructure. Most of the tutorials runs on [Play with Docker Platform](https://labs.play-with-docker.com/) & [Play with Kubernetes Platform](https://play-with-k8s.com). This is a free browser based learning platform for you. Docker tools like Docker Engine, Docker Compose & Docker Machine are already installed. Hence, we have everything ready for you to get started with.

## Getting Started in 3 Simple Steps

# Categories

DockerLabs is a tutorials authored by members of the open community. Below are the list of categories:

## Docker

## Kubernetes

# A Quick Reference

## Getting Started with Docker

Interestingly, you don't need to do any investment. Throughout the tutorial, you will be using Play with Docker (PWD in short) Playground. Cool....Isn't it?

PWD is a Docker playground which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Alpine Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters in Docker Swarm Mode. Under the hood Docker-in-Docker (DinD) is used to give the effect of multiple VMs/PCs.

To get started with Docker, follow the below steps:

  • Create Dockerhub Account
  • Open [Play with Docker Platform](https://labs.play-with-docker.com/)
  • Click on "Start"
  • This will open up an easy to understand PWD(Play with Docker) tool which displays instances on the left hand side while terminal at the right hand side
  • Click on "Create Instance" to create your first Linux instance

## Getting Started with Docker Swarm

To get started with Docker Swarm, you can use "Play with Docker", aka PWD. It's free of cost and open for all. You get maximum of 5 instances of Linux system to play around with Docker.

  • Wait for few seconds to bring up 5-Node Swarm Cluster

We recommend you start with one of our Beginners Guides, and then move to intermediate and expert level tutorials that cover most of the features of Docker. For a comprehensive approach to understanding Docker, I have categorized it as shown below:

# A Bonus... Docker Swarm Visualizer

Swarm Visualizer is a fancy tool which visualized the Swarm Cluster setup. It displays containers running on each node in the form of visuals. If you are conducting Docker workshop, it's a perfect way to show your audience how the containers are placed under each node. Go..try it out..

## Clone the Repository

`docker git clone https://github.com/dockersamples/docker-swarm-visualizer `

`docker cd docker-swarm-visualizer docker-compose up -d `

To run in a docker swarm:

```docker $ docker service create

--name=viz --publish=8080:8080/tcp --constraint=node.role==manager --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock dockersamples/visualizer

```
