  3. dredge

    Dredge: A Container Registry Client CLI

    Dive is great. Tools like that are critical for both learning and developing confidence on what you are precisely building/shipping.

    Dredge is another tool to look at. I use it for diffing layers.

  4. image-spec

    OCI Image Format

    Eventually, once zstd support gets fully supported, and tiny gzip compression windows are not a limitation, then compressing a full layer would almost certainly have a better ratio over several smaller layers

  5. cli

    🖥️ Depot CLI, build your Docker images in the cloud (by depot)

    Dive is an amazing tool in the container/Docker space. It makes life so much easier to debug what is actually in your container. When we were first getting started with Depot [0], we often got asked how to reduce image size as well as make builds faster. So we wrote up a quick blog post that shows how to use Dive to help with that problem [1]. It might be a bit dated now, but in case it helps a future person.

    Dive also inspired us to make it easier to surface what is actually in your build context, on every build. So we shipped that as a feature in Depot a few weeks back.
