Problem
In some corporate environments, the use of docker desktop is not allowed due to licensing issues. However, docker community edition running on wsl2 is supported. It is possible to run docker on wsl2, and connect to it from intellij following the steps noted in this gist: https://gist.github.com/sz763/3b0a5909a03bf2c9c5a057d032bd98b7 . Additionally, if a container needs to access the filesystem, this is nice https://github.com/testcontainers/testcontainers-java/blob/main/core/src/main/java/org/testcontainers/utility/PathUtils.java#L63 but insufficient, because on the WSL side it needs to be prepended with /mnt (assuming the path is something like /c/parentdir/targetdir .
Solution
- enhance the documentation here: https://java.testcontainers.org/supported_docker_environment/windows/ to also mention how to run testcontainers without docker desktop
- possibly autodetect platform and enable calling the mingw path utility and prepending/mnt depending on platform detected (look at environment variables, possibly have an environment variable to signal that wsl is being used as the docker host)
Benefit
Windows IDE users who cannot get a docker desktop license will not be excluded from writing good tests.
Alternatives
Users are currently able to run testcontainers without docker desktop on windows, but have to scrounge around the internet for information. Some IDEs can run natively in wsl2, but especially for IDEs like intellij this is a tricky, painful process.
