How to self-host Whoami

Whoami can be deployed with standard Docker Compose using the Yantr app catalog. This page collects the basic information searchers usually need first: what Whoami does, which Docker image Yantr uses, default ports, dependencies, and where to find the original compose template.

If you searched for Whoami Docker, Whoami Docker Compose, or self-host Whoami, this page is the direct landing page for that app in Yantr's catalog.

After deployment, Yantr also lets you publish additional ports later from the stack page using Docker-style syntax. Use mappings like 8080:8080 for a fixed host port or just 8080 to let Docker assign a random host port for container port 8080.

Use Cases
