Instructions on how to develop on mac with minikube

Preparation

  1. Install minikube v0.19

  2. Install xhyve driver.

    brew install docker-machine-driver-xhyve
sudo chown root:wheel $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve
sudo chmod u+s $(brew --prefix)/opt/docker-machine-driver-xhyve/bin/docker-machine-driver-xhyve

  3. Start minikube:

    minikube start --vm-driver xhyve

Note: make sure to allow network communication from the virtual machine by disabling firewall restrictions. If you use wireless network, you might need to restart the VM after sleep since the network can be flaky. The error manifests in inability to pull images.

Build and test

  1. Mount repository root to minikube host folder:

    # In the repository root directory; the daemon must stay alive for the duration of the build/test
minikube mount .:/pilot

  2. Start the build pod:

    kubectl apply -f doc/bazel.yaml

  3. Run bazel build and test

    kubectl exec bazel -it bash
cd /pilot

# make sure platform/kube/config exists; touch an empty file to use the minikube cluster for testing
# Symlinks to ${HOME}/.kube/config will not work.
sudo touch platform/kube/config

sudo -E bazel test //... --symlink_prefix=/ --test_env KUBERNETES_SERVICE_PORT --test_env KUBERNETES_SERVICE_HOST

Note: the base image runs under user jenkins while the shared directories are owned by the root; hence, the need to use sudo and passing environment with -E flag.
