I am trying to run a yum or apk in a Docker image . I first took openjdk and in the dockerfile I kept a yum -y update command . I got Yum not found error .
How can I find if a docker image can allow yum in it or not ?
and how for images without yum , how do I install it ?
new to docker . Please forgive me if the query is very basic . Appreciate your help.
