Official Docker Image

[ognots]

As part of the Lotus release process, create Docker image(s) containing all lotus binaries.

Guiding Principles

• Runtime environment(s) should have required packages and libraries installed using latest acceptable versions. For lotus-miner and lotus-worker a viable GPU runtime should be included, likely based on nvidia/opencl. Likely an Ubuntu based image.
• Should be deployment agnostic. No scripts or custom entry points or general opinions on how to run binaries should be included
• Be a building block for custom Docker images. Any customization should occur as a further layer on top of this image, using this image as the FROM source
• lotus-miner and lotus-worker binaries should produce native builds setting RUSTFLAGS="-C target-cpu=native -g and FFI_BUILD_FROM_SOURCE=1 - blocked by Upgrade blst to fix cross cpu architecture binary incompatibilities  #3339
• images should be published to multiple sources, not just Dockerhub which has recently introduced restrictions on image pulls
• include all binaries from lotus. grouping of binaries in individual images to be determined

There is an issue open currently to update the nvidia/opencl container to support ubuntu 20.04 but it appears that nvidia might no longer be maintaining the containers any longer. https://gitlab.com/nvidia/container-images/opencl/-/issues/3

This might require that we add the opencl support our selves and maintain the images or find an alternate base image for opencl.

Now that #5394 is merged, it is very easy to extend the initial Dockerfile (https://github.com/filecoin-project/lotus/blob/master/Dockerfile.lotus pretty much copy-pasted from https://github.com/filecoin-project/lotus-infra/tree/master/docker) (currently contains only lotus and lotus-shed binaries) and add any other binaries we might need - either in the same image, or as a separate image pushed to a separate public registry.

@nonsense https://github.com/filecoin-project/lotus-infra/tree/master/docker is 404 now.

Can we run Docker.lotus and be done or is that still just a step in setting up?

I believe with #9625 and associated fix #9826 this should be complete now.
