  What is docker?!? Dockeris an open platform for building, shipping and running distributed applications. It gives programmers, development teams and operations engineers the common toolbox they need to take advantage of the distributed and networked nature of modern applications. Note: ● build, ship and run distributed applications ● common toolbox for all - dev, test, prod

  Container vs VM VMContainers
• 5.
  Why use docker?!? -Development environment is same as prod environment - Develop with docker - No dependency hell - Deployment is a breeze - Lightweight - High portability - Microservices

  Swarm - Introduction ●Native clustering service ● container scheduling made easy ● scales well ● Works with all existing Docker Tools
• 7.
  Clustering with swarm 1.Swarm Master ● Create cluster ● Start swarm master ● Join nodes 2. Swarm Node(s) ● Run docker engine in daemon mode ● Make sure all nodes are joined $swarm create $swarm manage $swarm join $docker -H <nodeIP>:2375 -d $docker -H <nodeIP>:2375 -d SwarmMaster Node Node
