## Build a development API Gateway Create `functions/gateway:latest-dev` ``` $ cd gateway/ $ ./build.sh ``` Now edit the gateway service in your `docker-compose.yml` file and deploy the stack. If you want to use an overriden name then pass in the tag to the `./build.sh` script such as `./build.sh test-1`. ## Hack on the UI for the API Gateway To hack on the UI without rebuilding the gateway mount the assets in a bind-mount like this: Remove the Docker stack, then create the faas network as "attachable": ``` $ docker stack rm func $ docker network create func_functions --driver=overlay --attachable=true ``` Now edit the `docker-compose.yml` file and add an attribute to the `functions` network of `attachable`. Now you can run the gateway as its own container and bind-mount in the HTML assets. ``` $ cd faas $ docker run -v `pwd`/gateway/assets:/root/assets -v "/var/run/docker.sock:/var/run/docker.sock" \ -p 8080:8080 --network=func_functions -ti functions/gateway:latest-dev ``` Now deploy the rest of the stack with: `./deploy_stack.sh`.
