Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to Host Shiny Apps on the DigitalOcean App Platform
On the next screen, leave the Type as Web Services, set the Run command to the CMD command of the Dockerfile that you are deploying (without the square brackets), and change the port to the one exposed by Docker (3838):

Best Practices for R with Docker
Caching can be useful is when installing R package dependencies. In a previous post, we looked at how to use the renv package to install dependencies. Here is a simplified snippet from that Dockerfile:

The worst thing about Jenkins is that it works
> We are uding docker-in-docker at the moment
You can also run a "less privileged" container with all the features of Docker by using rootless buildkit in Kubernetes. Here are some examples:

It's also possible to run dedicated buildkitd workers and connect to them remotely.

Show HN: Dockerfile Explorer
- BuildOp evaluates its input as additional LLB operations to add to the graph to allow for dynamic build graphs (also unused in the Dockerfile frontend)
With the Dockerfile Explorer, we run the Dockerfile frontend[1] that BuildKit uses inside of WASM to parse and produce the LLB output locally in your browser. We then embed the Monaco Editor so that you can change your Dockerfile to see how it impacts the LLB output that BuildKit will use to build your Docker image.
You can see a quick video and read more details on how it all works here: https://depot.dev/blog/dockerfile-explorer.
We'd love any feedback or ideas folks would like around this type of tool!

Jenkins Agents On Kubernetes
Now since Kubernetes works off of containerd I'll be taking a different approach on handling container builds by using nerdctl and the buildkit that comes bundled with it. I'll do this on the amd64 control plane node since it's beefier than my Raspberry Pi workers for handling builds and build related services. Go ahead and download and unpack the latest nerdctl release as of writing (make sure to check the release page in case there's a new one):

Frequent Docker BuildKit cache misses with w/ multi-stage and docker-container
There's a 2-year-old moby/buildkit GitHub issue about frequent build cache misses when using the BuildKit docker-container driver and multi-stage builds. Anyone else in this sub run into this problem and/or have reasonable workarounds? It seems like something that should come up pretty often.

A Panic in BuildKit: an Open Source Journey
A couple months ago I encountered a bug in buildkit - when enabling OpenTelemetry tracing, we got occasional panics. With a bit of investigation, we found the cause, fixed and tested in our fork and internal deployments, and pushed to upstream.

Is it possible to copy files from a manifest in Dockerfile?
I do some search in the internet and there seems to be no good solution, so I just create a feature request: https://github.com/moby/buildkit/issues/3859

Cicada - CI/CD platform written with Rust
Yeah, only Linux containers at the moment, BuildKit is the way we are constructing pipelines and doing caching. Split on if we will support non-linux hosts, but definitely want to find a good solution to not doing Docker-in-Docker.
