Follow the author on Twitter “Numbers, if analysed the right way, not only tell a story but can also predict the future.” The pictures displayed above have been taken from the “dockercon 2016” slide deck presented by Ben Golub. The data clearly indicates the fact that Docker is fast becoming one of the most popular and widely […]
As discussed in the last video, “docker for azure” are templates that are used for automating the task for infrastructure & docker node deployment. The template is JSON based & provisions multiple Azure resources at the click of a button. Hence its very important that we understand the Json template & the resources that are provisioned. In this video i […]
Towards the end of June 2016, Docker announce the released of “Docker for Azure” & “Docker for AWS”. Using these templates it is now possible to create both the Docker Cluster for orchestration of containers as well as the underlying Infrastructure clusters on Azure from a single touch point. These templates significantly reduce the time to setup the docker swarm […]
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.
