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.
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"),
