  Description of Issue

  My friend can not join using the epic game store version of ark. Probably the -crossplay parameter needs to be passed, but i could not figure a way out to do so. Connecting via Steam works.

Fascinating. Had no idea ARK was in the Epic Game store now. I believe you need either one or both of the following flags to be set:

• -crossplay
• -epiconly

You can set flags on this image by using an environment variable with the prefix am_arkflag_<optname>=<anything>.

So you might try with one or both of the flags I listed above, like this:

• -e am_arkflag_crossplay=""
• -e am_arkflag_epiconly=""

I'm not sure if the -epiconly flag is actually required. Unfortunately, I don't have a copy of the EpicGames version of ARK to test with, but I'd love to hear back on whether or not this works for you.

Also, just a tip, your mounts for steam and ark should look like the following:

• -v steam:/home/steam/.steam/SteamApps/workshop
• -v ark:/ark

EDIT: Looks like you should only need -crossplay based on the patch notes here: https://survivetheark.com/index.php?/forums/topic/388254-pc-patch-notes-client-v31187-server-v31197/

@thmhoag Just to clarify on this, the flag should be

-e am_arkflag_crossplay="true"

not with an empty parameter. I was able to get both Steam and EGS users to connect this way.

Thank you both :)

The volumes were just a copy and paste error.

Thanks for the clarifcation @jcoker85. I'll update the README.md with this info for others to see in the future.
