Debugging provider plugin in a live Pulumi program
Raw
Instructions.md
  1. Install dlv - https://github.com/go-delve/delve/tree/master/Documentation/installation
  2. Compile and link k8s provider with optimizations off - https://github.com/pulumi/pulumi-kubernetes/commit/3681117730a6440d89e697bc6ae46141fb965d8d (make build && make install && yarn link "@pulumi/kubernetes")
  3. Compile pulumi/pulumi with dlv WIP - https://github.com/pulumi/pulumi/commit/50414ca053981af7560b17df72a0251b9ac2ec03 (make build && make install)
  4. Run the dlv WIP pulumi binary (~/go/bin/pulumi up --logtostderr -v4 --logflow)
  5. Connect GoLand remote debugger to localhost:2345

Current Limitations:

  • Only works for k8s provider
  • Attaches to first launched process of the k8s provider
  • No first-class "debug mode" in pulumi bin; requires manual compilation
  • k8s provider make flags are not conditional
  • Program timeouts are still active
  • dlv doesn't always exit cleanly, requiring manual process cleanup (pkill dlv && pkill pulumi-resource-kubernetes && pkill pulumi-language-nodejs)
  • Only tested with GoLand on MacOS (should be possible to connect other programs to the headless dlv instance)
