What happened?

  • I tried running all the tests on podman. Some don't work as ryuk is enabled.
  • After disabling ryuk using: os.Setenv("TESTCONTAINERS_RYUK_DISABLED", "true") the tests work fine.
  • Maybe, we can check if the system has podman and disable ryuk for them as podman is quite heavily used by Linux users.
  • Will help in onboarding more contributors to the project.

Relevant log output

Error:          Received unexpected error:
                                create container: container create: Error response from daemon: container create: unable to find network with name or ID bridge: network not found: creating reaper failed

Additional information

Alternatively, we can simply mention in the docs that everyone has to export TESTCONTAINERS_RYUK_DISABLED=true before running the tests on Podman.
