I thought I had this working a few minutes ago:

How do I check that the container connection is accessible? I'm trying:
root $ root $ telnet 127.0.0.1 3306Trying 127.0.0.1...Connected to 127.0.0.1.Escape character is '^]'.J8.0.21%#%T:/]T�e-r&UR([/caching_sha2_password^CConnection closed by foreign host.root $ root $ root $ telnet 127.0.0.1 33060Trying 127.0.0.1...telnet: Unable to connect to remote host: Connection refusedroot $ but that seems a bit odd.
