-- [zenithdb/build](https://hub.docker.com/repository/docker/zenithdb/build) — image with all the dependencies required to build Zenith and compute node images. This image is based on `rust:slim-buster`, so it also has a proper `rust` environment. Built from [/Dockerfile.build](/Dockerfile.build).
 - [zenithdb/compute-tools](https://hub.docker.com/repository/docker/zenithdb/compute-tools) — compute node configuration management tools.

 1. Image `zenithdb/compute-tools` is re-built automatically.
 
-2. Image `zenithdb/build` is built manually. If you want to introduce any new compile time dependencies to Zenith or compute node you have to update this image as well, build it and push to Docker Hub.
+2. Image `zenithdb/compute-node` is built independently in the [zenithdb/postgres](https://github.com/zenithdb/postgres) repo.
