Using client.http to explore the application!
F1 in vscode and choose Remote-Containers: Open Folder in Container..., then waiting until it build sucessful
# check linux version
> cat /etc/os-release
# build all images of application
> docker compose build Open a new tab
> cd local/
$ sudo chmod +x core-libs.sh start.sh
$ sudo ./core-libs.sh
# nomad cannot run on wsl2 image, then we need to work-around
$ sudo mkdir -p /lib/modules/$(uname -r)/
> echo '_/bridge.ko' | sudo tee -a /lib/modules/$(uname -r)/modules.builtin
# Start nomad and consul
> ./start.shOpen another new tab
