The @containerd.dev maintainer session is underway at #KubeCon EU in London with an awesome cross-section of contributors and maintainers from both the core project and subprojects like nerdctl and runwasi.

We'll be talking about @containerd.dev in just about an hour! Come join us in Platinum Suite Level 3 Room 3-4 at 5:30!

Mount Ollama binary • Mount the Ollama binary from the host into the container config. Mounts append(config. Mounts, specs. Mount Source: "/usr/bin/ollama" Destination: "/usr/bin/ollama", Type: "bind". Options: []string("rbind", "ro"}, })

Mount OCI as a Modelfile • Ollama needs to read the GGUF from a Modelfile file modelPath: getTaskEnv ("OLLAMA_MODEL PATH", config.Process.Env) modelfile: fmt.Sprintf("FROM %s", modelPath) err = os.WriteFile(filepath.Join(tempDir, "Modelfile"), []byte (modelfile), 0644) if err != nil { return nil, err } config.Mounts append(config.Mounts, specs. Mount( Source: filepath.Join(tempDir, "Modelfile"), Destination: "/tmp/Modelfile", Type: "bind", Options: []string("rbind", "ro"}, })

Serve the Model Set the container args to serve the model using Ollama config.Process.Args = [] string( /bin/bash", "-c". strings.Join([]string{ "ollama serve &", "while ollama ps> /dev/null 2>&1; do sleep 1; done", "ollama create modelName + --file/tmp/Modelfile", "tail -f /dev/null", }, "\n"),

This is pretty cool: a @containerd.dev shim to run LLMs with ollama. The shim augments the image by mounting in the ollama binary, generating a Modelfile as input to ollama (based on the model bundled in the image), and setting an entry point.

It's been a few weeks, but I have a new @containerd.dev internals blog post about images!

We released containerd 2.0 this week, with new features, now-stable features, and deprecations.
