Dockerfile CMD does not support multiple commands for mysql image

Question

Try running the mysql5.7 image with the datadir flag and include the bash script in CMD. CMD["--datadir=/data;shdb_translations.sh"] What ends up happening is that the container runs and creates a folder called data for mysql;shdb_translations.sh. Any idea why this is happening?

While many containers treat bash /sh as ENTRYPOINT and this works, for mysql containers, >ENTRYPOINT Already a script, it will only accept the provided CMD and will not re-evaluate in script form.

See using /docker-entrypoint-initdb.d as the script location for each document - https://hub.docker.com/_/mysql, although you may need Reorganized scripts and environments.
