creating reaper failed: could not start container: dial tcp: i/o timeout #279
Description
Got to see failed to create container: creating reaper failed: could not start container: dial tcp: i/o timeout in a docker-in-docker situation, whereas in the container (where testcontainers-go runs) the /var/run/docker.sock file (from the host) is mounted. Not even sure what exactly tries to TCP-connect() to where exactly, but clearly that TCP connection fails dial tcp: i/o timeout.
Worked around this, for now, with SkipReaper: true. Would appreciate any pointers / ideas for why this happens, and what can be done about this! Can the reaper container be started with the equivalent of --net=host? What are the downsides of skipping the reaper, really?
Using Go 1.15.6 and github.com/testcontainers/testcontainers-go v0.9.0.
