Using Containers for software testing
Containers are great to deploy software and also to test container images before deploying them.
But sometimes you want to just install software manually inside a "sandbox".
On Windows the Sandbox is a great way to test. On Linux you can just run a container.
In my current test case I am using a Redhat UBI Init image, which provides systemd support.
Usually systemd isn't what would be the right choice for a container image.
Containers usually run a single application/process and a entrypoint script is the right choice.
But for testing a container with systemd is an interesting option.
It requires a privileged container to support systemd -- which should be avoided for production environments.
For testing this is perfectly OK.
Run a new container
docker run -d --name init --privileged registry.access.redhat.com/ubi9-init:latest
Jump into the container
docker exec -it init bash
In my case I using it for end testing Domino installations.
I have updated the Domino native install script to work in this environment.
But there are many different use cases.
