Hacking: ## Hacking
First run faas-containerd
```sh
cd $GOPATH/src/github.com/alexellis/faas-containerd
go build && sudo ./faas-containerd
```
Then run faasd, which brings up the gateway and Prometheus as containers
```sh
cd $GOPATH/src/github.com/alexellis/faasd
go build && sudo ./faasd
```
Look in `hosts` in the current working folder to get the IP for the gateway or Prometheus
```sh
127.0.0.1 localhost
172.19.0.1 faas-containerd
172.19.0.2 prometheus
172.19.0.3 gateway
```
Since faas-containerd uses containerd heavily it is not running as a container, but as a stand-alone process. Its port is available via the bridge interface, i.e. netns0.
Removing containers:
```sh ```sh
echo faas-containerd gateway prometheus |xargs sudo ctr task rm -f echo faas-containerd gateway prometheus |xargs sudo ctr task rm -f
