In the swarm mode the docker engine maintains the desired state and is able to orchestrate the containers in order to attain fault tolerance. As and when a container within a swarm fails, the leader gets the information and immediately gives an order to create a new container from the base image. Such self healing capabilities of the ephemeral containers […]
As we discussed in the previous blog posts docker swarm mode provides in-built orchestration capability straight out of the box. We can use the docker Service API to create services composed of multiple instances of a container from the same base image. As all the containers are made from the same image they are ephemeral in nature and can be […]
In order to manage the global cluster state Docker Swarm uses the RAFT consensus algorithm for the manager nodes. RAFT is a leader based algorithm and can tolerate up to (N-1)/2 failures and requires a majority or quorum of (N/2)+1 members to agree on values proposed to the cluster. This means that in a cluster of 5 Managers running Raft, if […]
Docker Swarm mode is the native docker clustering system. It serves the standard docker API and exposes several docker engines as a single virtual engine. With the addition of these features docker is finally production ready and now organisations of any scale can start planning their CI/CD pipelines around docker swarm. This video is the 1st of a series of hands […]
In this video i explain the concepts behind docker swarm orchestration & the algorithms used by the docker engine to achieve the same.
In this video I discuss the feature set of the docker swarm mode. This video is a part of a series of many videos that i would be creating for explaining the functionalities of the swarm kit.
In this video I discuss the basics of docker swarm mode. This video is the first in the series of many videos that i would be creating for explaining the functionalities of the swarm kit.
