Hi I was following the official mysql cluster documentation for creating a MySQL cluster on Docker.
https://hub.docker.com/r/mysql/mysql-cluster
However when I looked at the logs I can see that the management node and the data nodes are failing with the following error.
[Entrypoint] MySQL Docker Image 7.6.18-1.2.2-cluster
[Entrypoint] Starting ndb_mgmd
MySQL Cluster Management Server mysql-5.7.34 ndb-7.6.18
ndb_mgmd: [ERROR] unknown variable 'user=mysql'
I have not configured any my.cnf or my-config.cnf files as I am just using the defaults. Any idea of what is happening?
