Init container that sets up the iptables rules to forward traffic into the Linkerd2 sidecar proxy

This repo contains the init container that reroutes all traffic to the pod through Linkerd2's sidecar proxy. This rerouting is done via iptables and requires the NET_ADMIN capability.

Integration tests

The instructions below assume that you are using minikube.

Start by building and tagging the proxy-init image required for the test:

eval $(minikube docker-env)
make image

Then run the tests with:

make integration-test

Build Multi-Architecture Docker Images with Buildx

Please refer to Docker Docs to enable Buildx.

Run make images to start build the images.

Run make push to push the images into registry. Registry repo can be configured with environment variable:

DOCKER_REGISTRY=<your registry> make push

In some local environments like Ubuntu, where the default Buildx builder uses the docker driver, the make images command might fail with the following error:

$ make images
multiple platforms feature is currently not supported for docker driver. Please switch to a different driver (eg. "docker buildx create --use")
Makefile:57: recipe for target 'images' failed
make: *** [images] Error 1

To fix this, you can create a new Buildx builder instance by running make builder. This command will create a builder that uses the docker-container driver that can build multi-platform images. For more information, see the Buildx builder documentation.
