This example shows

On server:

1. Install Zrok (only needs done once)
2. Setup Zrok account: zrok invite (only needs done once)
3. Connect to Zrok network: zrok enable SHARE_ID
4. Start service you want to share (such as Minecraft)
5. Expose port via Zrok:

Containers 101

What Are They Good For?

• Containers package and run Linux software in reproducable ways (similar to bundling an Anaconda environment into a single file that can be shared)
• Portability: anyone with Docker can run your container
• Isolation: containers cannot modify the host unless given explicit permission
• Reproducability: containers run the same code the same way on every host
• No need to worry about library versions or dependency webs (everything is self-contained)
• Docker Hub: many easy-to-install pre-built containers
