This will dramatically speed up your testing process.ĭeployment with Docker is also simple and easy. You can set up containers for your databases as well. To test your application in different versions of Java, you can simply run your application in multiple containers. Similar to the development example, the ability to spin up many Docker containers based on specific custom images make it much easier to have many representative test environments. And this is only complicated by developing and running in virtualized environments.

Test environments can be even more challenging because they will likely represent a larger number of run-time variations - for example, different frameworks and databases, different versions of Java, and so on. If your task is complicated by the need for different versions of Maven and Java, you can easily get the matching Docker image for each version and develop/run in isolation. But with docker, you simply obtain a Maven image from the Docker Hub and use it to develop, test, and run your application. Setting up an individual development environment is time consuming, particularly if multiple environments and toolsets are needed across development teams or geographies.įor example, if you are developing a Java/Maven-based application without Docker, you must install the JDK and Maven on your host machine. Docker containers provide the flexibility and the isolation you need to create development and test environments to match the many production environments your application is likely to accumulate over its lifetime.
