The problem we’ve just described is relevant when you’re building monolithic applications. What do microservices and Docker have to do with the situation above? Add in three more environments – staging, testing, and production servers – and you start to get an idea of how difficult it is to assure uniformity across development, testing, and production environments. Still, it’s almost inevitable that libraries and languages will conflict across these three different development environments. Each developer consults 20 pages of instructions on installing various libraries and programming languages and gets things up and running. These three (surprisingly unrelated) developers use three different environments to develop the very same app, and each environment requires its own unique setup. Finally, yet another Doe – Jason Doe, the third member of your team – has decided that he works best on Debian. Jane Doe, a co-worker of John’s, works on Windows.

Imagine you have a certain John Doe on your web development team who uses a Mac. To help you understand what microservices are and how Docker helps implement them, let’s start with a plausible example. Thanks to Docker, it’s now easier to construct scalable and manageable applications built of microservices. The development of server-side web applications has changed greatly since Docker’s debut.

This means that the production deployment is only executed when a human approves the deployment. In the future, you could add an approval before the production gateway. To achieve that, add the dependsOn keyword and the following condition. Lastly, we only want to deploy to production when the deployment to the test environment is finished and was successful. Since I don’t want to use a subdomain for my production URL, remove it which means the URL will be Next up replace test with prod, for example, the DeploymentEnvironment variable is now prod. Copy the deployment of the test environment and copy it beneath it. Add the Production environment to the CD PipelineĪdding a new environment is quite easy.

That is everything you have to update for the test environment.

For the test environment, I will use test as a subdomain which means the URL will be Īdditionally, add the environment name also to the database so you can distinguish the test and production databases. You don’t have to use a subdomain but this makes the configuration of the DNS settings easier.

I plan to change the URL of the test environment and then add a deployment of the Helm package and the database to a production environment.įirst, add a new subdomain to the URL of the test environment. So far, I have used the CD pipeline to deploy to a stage called test.

You can find the code of the demo on GitHub. Update the existing Deployment to the Test Environment

This post is part of “Microservice Series - From Zero to Hero”. In the following post, I will add a deployment to the production environment, set up a unique URL, and also deploy the database for the environment. Especially when you already have a CD pipeline, it is easy to extend it and deploy it to additional environments. A nice feature of Kubernetes is that you can easily set up new environments like test, QA, or production.
