To create this service, execute the following: Create a third Kubernetes service for your svc3 deployment and serve it via the path svc2.your-domain/bin. In order to route requests for svc2.your-domain/bin to svc3, you have added the second annotation block here as the host value svc2.your-domain, which is the same for both of the blocks. The API for spaces is a different schema at a different abstraction level (XML and actual file objects) than the normal "control" API. DigitalOcean API Implementation of the DigitalOcean API (v2) for .NET Standard 2+ Install. Finally, run the following command to apply: You’ve deployed three web server containers using Kubernetes deployments. Once you have exited the editor you’ll see output similar to the following: Check svc1.your-domain using curl for the content-encoding header having value gzip: Here you can see the default HTML page of Nginx with its response header showing that content-encoding of the received response is gzip compressed. It acts as a reverse proxy, routing requests from clients to services. AWS displays a message about creating an example API. The API does not return the droplet IP or password when it is created so you can't send the login details to your clients. You can find further details about deploying Amabassador to Kubernetes via YAML in Ambassador’s documentation.
