Blue-green Deployments

Set up the “blue” environment, running version one of the address service:

1. Create an upstream:

2. Add two targets to the upstream:

    curl -X POST http://localhost:8001/upstreams/address.v1.service/targets \
        --data "target=192.168.34.15:80"
        --data "weight=100"
    curl -X POST http://localhost:8001/upstreams/address.v1.service/targets \
        --data "weight=50"

4. Finally, add a route as an entry-point into the service:

        --data "hosts[]=address.mydomain.com"

Requests with host header set to address.mydomain.com will now be proxied by Kong Gateway to the two defined targets. Two-thirds of the requests will go to http://192.168.34.15:80/address (weight=100), and one-third will go to http://192.168.34.16:80/address (weight=50).

Before deploying version two of the address service, set up the “Green” environment:

Incoming requests with host header set to address.mydomain.com are now proxied by Kong to the new targets. Half of the requests will go to http://192.168.34.17:80/address (weight=100), and the other half will go to (weight=100).
