Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

Webassembly, wasm files, webservers and MIME types

When compiling client files to webassembly, usually you'll end up with both .js and .wasm files. By default, most webservers don't know about the wasm MIME type. You'll likely see the following error: wasm streaming compile failed: TypeError: Failed to execute 'compile' on 'WebAssembly': Incorrect response MIME type. Expected 'application/wasm'.

Here is how to add the wasm MIME type (on linux systems, apache + nginx):

Open /etc/mime.types You'll see two columns, media type on the left, file type on the right Add the line application/wasm wasm

AutoSSH Tunnel Config

Create a new local tunnel user to keep the .ssh/config clean

sudo useradd -g nogroup -s /bin/false -m tunnel
sudo -u tunnel mkdir -p ~tunnel/.ssh  # and copy your private key here
sudo -u tunnel nano ~tunnel/.ssh/config  # add host and key configs here and a myhostsshconf (or other name)
sudo -u tunnel ssh myhostsshconf  # just make sure to add your host to `known_hosts`

Create a new systemd service with the same name than an entry in the .ssh/config (myhostsshconf in this example)
