Try using Kong + Konga with Docker Compose.

What is Kong

This method is exposed in the form of Gateway Aggregation in Microsoft's design pattern.

Use the gateway to aggregate multiple individual requests into a single request. This pattern is useful when the client needs to make multiple calls to different back-end systems in order to perform the operation.

In general, creating a service with a microservices architecture creates multiple connections between the application and the server. This makes connection information management and error handling complicated. Therefore, it is conceivable to put something like a reverse proxy in between so that it looks like one to the application. This is gateway aggregation.

This time, I used something called Kong, but Sentinel and Gloo are also famous.

Image to use

kong https://hub.docker.com/_/kong

konga https://hub.docker.com/r/pantsel/konga/

What is konga? It's a Web UI for kong. The commercial version of kong has a WebUI, but it is not the OSS version. Therefore, we use OSS called konga to serve WebUI.

Settings and points

Select from the CONNECTIONS pane on the left to create a CONNECTION. At that time, enter http: // kong: 8001 / in Kong Admin Url. No SSL, as it is for easy local verification. The domain is kong, not localhost.
