Enabling bridge and br_netfilter modules in vanilla WSL2 (Ubuntu-22.04) to implement service-mesh in Hashcorp Nomad or Kubernetes.

Enable the bridge and br-netfilter modules on WSL2. This allows you to use "bridge" network mode for Hashicorp Nomad jobs. I believe it also works for Kubernetes.

These are minimal steps that I have tested in various environments using WSL2 with Ubuntu 22.04 vanilla.

All steps presented here are performed in the WSL2 terminal.

---

1. Create kernel module directory if it does not exist

# On wsl2 terminal.

sudo mkdir -p /lib/modules/$(uname -r)

2. Create modules.builtin file in to kernel module directory

# On wsl2 terminal.

sudo tee /lib/modules/$(uname -r)/modules.builtin <<-EOF
kernel/net/bridge/bridge.ko
kernel/net/bridge/br_netfilter.ko
EOF

3. Restart wsl2:

# On wsl2 terminal.

wsl.exe --shutdown

Reopen wsl2

Have fun!
