Inlets examples

This repo contains examples to use github.com/inlets/inlets(-pro).

Example 1: with docker-compose

docker-compose.yaml contains a layer 7 sample where the docker-compose service named server exposes a port to the host and in the background an inlet tunnel is used to connect to the service named web.

Example 2: with two kind clusters and a classic/legacy service

• use k8s/start.sh k8s/stop.sh to start or stop the example.

• example uses two kind clusters: one for a cloud-native cluster and one that acts as a bridge between classic/legacy and the cloud-native cluster

• from the cloud-native cluster it is possible to reach a classic/legacy service by k8s means:

    ```
    kubectx kind-cloud-native
    k exec -it -n default netshoot-deploy-<TAB> -- curl classic-service
    ```
  

• from the classic/legacy part the service svc of the cloud-native cluster is accessible:

    ```
    cd 0-classic && docker-compose up connecttocloudnative
    ```
