While setting up continuous delivery for your product, one of the biggest challenge is to implement continuous testing. We are gradually moving away from manual testing to automation. But how do we integrate the automated tests into your system? How to run integration tests everyday considering that the test environment can get polluted with failed tests? Docker is a type of a virtualisation platform, a container. Shippable is a hosted cloud platform that provides hosted continuous integration, deployment, and testing to GitHub and Bitbucket repositories.

- 23. @muktaaDevOps@WhiteHedge.com Shippable Formations (Contd.) Fully orchestrated, persistent, and 'smart', i.e. they can automatically update themselves when any new code is committed into any component of the application. Ensures that your Dev and Test labs always run the latest code and are reliable indicators of how that code will behave in production.

- Assumption: everyone knows about docker. If not, then 2 min explaining what is docker.
- Prior to code integration to trunk, developers pre-flight test their code to make sure it doesn’t blow up the trunk. During the CI cycle and code commits from multiple developers integration testing is used to verify merges. During the continuous testing phase where nightly and weekend regression runs are automated for trunk and release branches it is testing that does the job of finding problems before the software release. During the development process the verdicts trends from testing are a primary measurement of progress. During the release deployment phase more testing verifies the release packages are ready for release. Rest assured test team, you are needed. What DevOps really does is bring testing into the mainstream of development processes, and avoids the problems created by having “big-bang” testing left to the end of the cycle, such as release delays, and quality issues.
- Shippable CI/CD: Shippable CI/CD is our Continuous Integration and Deployment Platform. It uses Build Minions, which are Docker-based containers to run your workloads. After building and testing your code, you can have Shippable create a Docker image from your Build Minion and push it to Docker Hub or Google Container Registry (private registry support coming soon!). Go to Shippable CI/CD Overview to learn more. Shippable Formations Shippable Formations gives developers an easy way to provision, configure, and deploy multi-container Dev and Test clouds (environments) with zero DevOps code. It is fully integrated with the updated Shippable CI/CD platform, and together, they create an automated, frictionless pipeline from source control to full-topology environments that can mimic your production environment or represent any combination of software component versions you'd like to deploy.
