Testcontainers-java: Docker check fails on Windows

[sideeffffect]

testcontainers doesn't work smoothly on Windows.
The check that is run at the very beginning _always_ erroneously fails on the first test (failing the whole test run):

Docker environment should have more than 2GB free disk space
java.lang.AssertionError: Docker environment should have more than 2GB free disk space

The workaround is easy, jut put testcontainers.properties in resources with this:

checks.disable = true

But this is still a bug.

But do you have more than 2Gb allocated to your Docker VM?

[sideeffffect]

Sorry, if I haven't explained it as clearly: yes, there is definitely more than 2 GB available
@rpliva could you please post here a screenshot?

[bsideup]

@sideeffffect could you please post the output of docker run -it --rm alpine:3.6 df -h?

Apparently you don't have 2Gb of space in Docker's VM. Please either increase it or remove unused images or something else.

if the issue remains after the cleanup, you can reopen this issue and we will continue the investigation.

[rpliva]

and Docker Desktop settings

[kiview]

It's not a problem of the settings (0 B used display might be a bug in the Docker UI here).
You can clearly see overlay 14.6G 13.4G 495.7M 97% / in your output above.

You can cleanup by e.g. running docker system prune.

[rpliva]

Yes, docker system prune helped and now I have more than 11GB free space and everything work.

[jannis-baratheon]

You can cleanup by e.g. running docker system prune.

For future visitors. Be careful with docker system prune. Make sure you know what you're doing.
