Use Your Favorite Developer Tools in Kubernetes With Telepresence
Talkat KubeCon + CloudNativeCon North America 2019 · on Wednesday, 2019-11-20· at 17:20· Exhibit Hall AB - San Diego Convention Center, Ground Level·
summary
Telepresence lets code run on a laptop while the Kubernetes cluster and API gateway treat it as if it were in-cluster, demonstrated by swapping a deployment (cluster scales original to zero and runs a Telepresence proxy) and by intercepting via Envoy/Ambassador to route only requests with header X-dev:123 to port 8000. Demos use IntelliJ for Java, VSCode for Node (and Rust), Delve for Go, Pdb for Python, and PGCLI for DB inspection; swap forwards all TCP and blocks others while intercept is HTTP-only, and UDP is not supported yet.
