error while running example

[Jay Ma]

Hello,

I am running docker on MacOS, and following the example.

However, I am stuck at 302_new_shards.sh 

After running the script, I am getting the following error:

Looking at the error log in /vt/vtdataroot/vt_000000040*/error.log, 

I see a lot of unknown database 'vt_customer'.

Any idea why I am getting this error?

Just in case, I ran the similar testing, without creating new customer keyspace, creating new shards in commerce keyspace (made sure all the commands are replaced with commerce), but I am getting the same error.

Please let me know if anyone sees anything I can try.

Looks like it's just a memory issue in the docker container.

spinning off multiple mysql instances with default memory settting in docker.

After setting 4gb from 2gb, it's working.
