How to create a wallet at the moment of running a p-rep docker image?

Is there a way to create a wallet to run a P-Rep node using docker image inside the container. Or in any case it is necessary to register it at https://www.myiconwallet.com/, then use those credentials to run a node. Thank you.

You can create a wallet anywhere and then copy keystore to your node.

Thank you for your answer, I wanted to create a wallet inside the container at the moment I start running it. But thats ok, Ill just use a Keystore Json
