Minikube

agentfile can start a Minikube cluster and make it accessible to the agent container via a built-in TCP forwarder — no socat required.

Prerequisites

Typical workflow

--minikube automatically prepares the Minikube kubeconfig for use inside the container. Because the container runs rootless and isolated from the host network, a plain copy of ~/.kube/config won't work. The certificate paths and server address need to be adjusted first.

agentfile handles this automatically. It extracts the minikube context from your kubeconfig, embeds any referenced certificate files directly, and rewrites the server address to one reachable from inside the container. The result is mounted at /root/.kube/config and cleaned up when the container exits.

In one terminal, start Minikube and the port forwarder:

agentfile minikube start

In a second terminal, run the agent with the kubeconfig mounted automatically:

agentfile run --minikube

agentfile minikube start

Starts Minikube if it isn't already running (or unpauses it if it is paused), then forwards the ephemeral apiserver port to a fixed port on all interfaces so the container can reach it. Blocks until Ctrl-C.

The defaults work for most setups. Override them if needed:

Flag Default Description
--host 169.254.1.2 IP passed to --apiserver-ips and used as the forward destination
--port 16443 Port to listen on for the TCP forwarder
--driver qemu2 Minikube driver (passed to --driver on start)

agentfile minikube kubeconfig

Generates the filtered kubeconfig that --minikube produces automatically. Useful for inspecting the output, saving it somewhere persistent, or using it outside of agentfile run.

# Print to stdout
agentfile minikube kubeconfig

# Write to a file
agentfile minikube kubeconfig -o /tmp/minikube.yaml
Flag Default Description
-n/--name minikube Context/cluster/user name to keep
-s/--server https://169.254.1.2:16443 Override the cluster server URL
-o/--output - (stdout) Output file path
--kubeconfig $KUBECONFIG or ~/.kube/config Source kubeconfig file
