Why should I use Docker containers with IMAS in a first place

If you find it hard to have your local IMAS installation, it might be you find yourself in plan to use IMAS components within one of these situations:

• you have as a user of a computing cluster but you don't have without root permissions to install new software,
• you need just a bare bones IMAS installation, with basic components, but you don't have a computing machine and manpower to install it,
• you don't have to time a manpower to perform regular upgrades of your local IMAS installation,
• you want to utilise Cloud resources.

Indeed, having a local IMAS installation may be a challenge. However, there is a solution. In case you need your private IMAS release, with slightly limited functionality, a it might be useful to look at a Docker based IMAS release if the way for you to go.

We have successfully used this approach across various projects and were able to deliver solutions from embedding single physical code to complex, micro-services based, server solutions. We were able to provide UDA server and UDA client based on IMAS inside Docker, we have released SimDB installations based on IMAS inside Docker, finally, we provide CI/CD based tests at https://gitlab.eufus.psnc.pl that are based on IMAS inside Docker. And all of that thanks to Docker images with IMAS inside.

Running CI/CD pipelines using Docker containers with IMAS

If you have wondered whether it is possible to use Docker based IMAS for running regular tests, the answer is: YES. This is perfectly possible. In fact ACH-04 team benefits from this approach every day, whenever we push changes to our code base. We test various projects using pipelines composed of layers of Docker containers.
