+# Minecraft in Dstack
+
+Existing Minecraft docker compose files work out of the box! 
+https://github.com/itzg/docker-minecraft-server/
+
+There are a few ways of connecting.
+
+Some slides on my minecraft notes so far: https://docs.google.com/presentation/d/1vFqlFeFFaEPlboymo_-EjASeu3kgKuXnmPc63abWcps/edit
+
+## For unmodified clients (server needs free ngrok api)
+
+
+To join my minecraft server w/ direct connection (via ngrok):
+```
+0.tcp.us-cal-1.ngrok.io:19314
+```
+
+Docker compose w/ Ngrok (works w unmodified minecraft client):
+- https://github.com/itzg/docker-minecraft-server/blob/master/examples/docker-compose-ngrok.yml
+
+
+## For client that is willing to run stunnel or socat
+
+Bare Minecraft docker compose (works if you use stunnel or socat on client):
+- https://github.com/itzg/docker-minecraft-server/blob/master/examples/docker-compose.yml
+
+With socat:
+```
+socat TCP-LISTEN:25565,bind=127.0.0.1,fork,reuseaddr OPENSSL:fd2cd876576b10d9f31924e8cb1604f1ad4e8f03-25565.dstack-prod5.phala.network:443
+```
+
+## To make a fully secure connection (for T-E-Esports)
+
+First to get a reference certificate:
+```
+openssl s_client -connect fd2cd876576b10d9f31924e8cb1604f1ad4e8f03-25565.dstack-prod5.phala.network:443 </dev/null | sed -n '/-----BEGIN/,/-----END/p' > pinned.crt 
+```
+
+then use a tunneling tool (stunnel) that can check against this reference:
+
+```
+stunnel ./stunnel.conf
+```
+
+Example `stunnel.conf`:
+```
+foreground = yes
+pid = ./stunnel.pid
+
+[minecraft]
+client = yes
+accept = 127.0.0.1:25565
+connect = fd2cd876576b10d9f31924e8cb1604f1ad4e8f03-25565.dstack-prod5.phala.network:443
+verifyPeer = yes
+CAfile = pinned.crt
+checkHost = fd2cd876576b10d9f31924e8cb1604f1ad4e8f03-25565.dstack-prod5.phala.network
+```
