Contribution guidelines

So you want to hack on Istio? Yay! Please refer to Istio's overall contribution guidelines to find out how you can help.

Prerequisites

To make sure you're ready to build Envoy, clone and follow the upstream Envoy build instructions. Be sure to copy clang.bazelrc into this directory after running the setup_clang script. Confirm that your environment is ready to go by running bazel build --config=clang --define=wasm=disabled :envoy (in this directory).

How to use a devcontainer

  1. Change the image in .devcontainer.json to build-tools-proxy instead of build-tools
  2. Open the directory in a container with the Remote - Containers extension
  3. Install the following extensions:
  4. Update clangd and reload the container
  5. Edit the new bsv.cc.compdb.targets workspace setting and set it to //:envoy_tar
  6. Execute Bazel/C++: Generate Compilation Database within vscode

Note: if you have a remote bazel cache or something mounted in your build container for your normal proxy builds, you'll need to configure that in the devcontainer with runArgs.
