phpMyAdmin using dockerised database I have installed mariadb inside docker container, and mariadb is running properly inside that container. I want to get access of mariadb through phpMyAdmin from outside docker container.

What will I have to do for that?
You need to 


Expose the server port in the Dockerfile
get the IP that the container is listening on (e.g. docker inspect code-rade_cache_1 |jq .[0].NetworkSettings.Networks[].IPAddress ) -- note that you will need JQ installed  on your computer to do this
Set the connection in the mysqlphpadmin
