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.
