+## Docker images
+
+We are publishing two different docker images on `tag` and on every commit to `main` branch:
+
+| | Gunicorn | Uvicorn |
+|          -- |     -- |   -- |
+main commit | `ghcr.io/developmentseed/tipg:latest` | `ghcr.io/developmentseed/tipg:uvicorn-latest`
+tags | `ghcr.io/developmentseed/tipg:0.0.0` | `ghcr.io/developmentseed/tipg:uvicorn-0.0.0`
+dockerfile | [/dockerfiles/Dockerfile.gunicorn](https://github.com/developmentseed/tipg/blob/main/dockerfiles/Dockerfile.gunicorn) | [/dockerfiles/Dockerfile.uvicorn](https://github.com/developmentseed/tipg/blob/main/dockerfiles/Dockerfile.uvicorn)
+
+See all version at https://github.com/developmentseed/tipg/pkgs/container/tipg
+
+```
+# Gunicorn image
+$ docker run \
+    -p 8081:8081 \
+    -e PORT=8081 \
+    -e DATABASE_URL=postgresql://username:[email protected]:5432/postgis \
+    ghcr.io/developmentseed/tipg:latest
+
+# or Uvicorn image
+$ docker run \
+    -p 8081:8081 \
+    -e PORT=8081 \
+    -e DATABASE_URL=postgresql://username:[email protected]:5432/postgis \
+    ghcr.io/developmentseed/tipg:uvicorn-latest
+```
+
+Note: If you are planning to use the docker image in a kubernetes deployment you may want to use the `uvicorn` image (ref: https://fastapi.tiangolo.com/deployment/server-workers/).
