In my previous blog, I talked about the first phase of a successful QA automation project built on a Docker environment. Now, I would like to describe the advantages we realized by using Docker, and some of the techniques we used to implement.
Typically, when we begin a new automation project, we spend significant time configuring our environment and fixing associated issues as they surface. With Docker technology, we just need to build a file that configures an environment that normally works “issue free” – avoiding the time spent in configuration and problem solving.
Docker is an open source software that allows us to package applications in a container, Containers are like a VM. However, they have a very important difference – a container can share the system kernel with others, which means we can run multiple containers (with their own user space) simultaneously run on a single host machine.
