Step 1: Log in to your Console
Step 2: Select Canary
Click on the Canary you want to configure the custom TCP service on.
Step 3: Configure Canary
Click on Configure Canary to configure this Canary.
Step 4: Edit Custom TCP Service
Scroll down to Custom TCP Service 1 and turn it on and enable Run this service on all unused ports.
Step 5: Deploy changes
Once you've made the changes you will then need to click on Deploy new configuration.
