Docker Cloud for AWS

Cloud Platforms, Containers & Kubernetes, ,

In this blog, I will cover Docker cloud usage with AWS. This blog is part of my Docker for AWS series and uses the sample voting application for illustration.

Docker cloud is a hosted service from Docker to manage Containers. Docker cloud is free to try for 1 private repository and node and is chargeable after that. Docker cloud was originally an acquisition from Tutum. Docker cloud can be used to manage infrastructure nodes in the cloud or nodes in the local data center. For basics on Docker cloud/Tutum, please refer to my earlier blog here. Since Docker cloud was an acquisition, it does not use some of the Docker ecosystem software. Following are some important differences:

Gopaddle Meetup Bangalore – CI, CD Presentation

Containers & Kubernetes, DevOps & Automation, , ,

Following link captures the slides on CI, CD with Docker, Jenkins and Tutum that I presented at GoPaddle meetup, Bangalore on January 23, 2015. You can find more details on the meetup here. In this presentation, I covered the following:

  • Overview of Continuous Integration(CI), Continuous deployment(CD)
  • Tutum Overview
  • Jenkins with Docker Integration
  • CI, CD Use cases with Docker and Jenkins, Docker and Tutum

CI, CD with Docker, Jenkins and Tutum

Containers & Kubernetes, DevOps & Automation, , ,

In this blog, I will give an overview of Continuous Integration (CI) and Continuous Deployment (CD) and cover few CI, CD Use cases with Docker, Jenkins and Tutum. Docker provides Container runtime and tools around Containers to create a Container platform. Jenkins is a CI/CD application to build, test and deploy applications. Tutum is a SaaS Container platform that can be used to build, deploy and manage Docker Containers. I have covered overview of Tutum in previous blog. There are Use cases where these applications work well with each other and the Use cases in this blog will illustrate that.

CI/CD Overview

Traditional approach of releasing software has the following problems:

  • Software release cycles were spaced apart which caused new features taking longer time to reach the customers.
  • Majority of the process of getting software from development stage to production was manual.
  • Considering the different deployment scenarios, it was difficult to guarantee that software worked in all environments and configurations.

Containers have tried to mitigate some of the problems above. By using microservices and Container approach, it is guaranteed that the application will behave similar in development and production stages. Process automation and appropriate testing is still needed for Container based environment.

Continuous Integration refers to the process of making an executable or a Container image automatically after developer has done the UT and commit.

Continuous delivery refers to the process of taking the developer built image, setting up the staging environment for testing the image and deploying it successfully for production.

Following diagram show the different stages of CI, CD cycle.

Tutum Introduction

Containers & Kubernetes, ,

Tutum is a SaaS Container platform that can be used to build, deploy and manage Docker Containers. Docker acquired Tutum in October 2015. I have been playing with Tutum for the past few weeks and I will share some basics of Tutum and my experiences with Tutum in this blog.

Advantages

  • Very easy to get started and create Containers and multi-Container applications
  • Works with majority of cloud providers like AWS, GCE and our own node can also be used.
  • Hides orchestration, networking and storage complexity.
  • Provides GUI, CLI as well as api access
  • Gives own private repository within Tutum per user, other repositories can also be used
  • Logging, monitoring, Scaling and HA is built-in
  • Does rolling upgrade automatically
  • Suited for CI, CD Usecases

What can we do with Tutum?

  • Build Docker images from Dockerfiles
  • Have a private repository in Tutum for storing Docker images and also interact with already existing repositories
  • Deploy single container and multi-container application in cloud provider or in our own machine
  • Integrate with Github for automatic Container image build and deploy Containers automatically using rolling upgrade
  • Monitor, debug, manage and upgrade Containers and Services

Getting Started

  • Need Tutum account – Free at this point since Tutum is still in Beta
  • Cloud provider account or own node
