Set a default service
Estimated reading time: 1 minuteThe default proxy service used by UCP to provide layer 7 routing is NGINX, so when users try to access a route that hasn’t been configured, they will see the default NGINX 404 page.
You can customize this by labelling a service with
com.docker.lb.defaul_backend=true
. When users try to access a route that’s
not configured, they are redirected to this service.
As an example, create a docker-compose.yml
file with:
version: "3.2"
services:
demo:
image: ehazlett/interlock-default-app
deploy:
replicas: 1
labels:
com.docker.lb.default_backend: "true"
com.docker.lb.port: 80
networks:
- demo-network
networks:
demo-network:
driver: overlay
Set up your CLI client with a UCP client bundle, and deploy the service:
docker stack deploy --compose-file docker-compose.yml demo
Once users try to access a route that’s not configured, they are directed to this demo service.
