Leader-elector sidecar container

This repo contains the election directory forked from kubernetes/contrib, later forked by openshift/leader-elector. The original version has not been updated since July 2016 and has security issues.

It was forked to change certain behaviour in the code, update some dependencies and include multi-platform builds equal to the platforms that the Instana Agent supports.

Info on how to use this can be found on Kubernetes blog.

Multi-arch Builds

Docker for Mac has all support for multi-arch builds included. For Linux hosts, some additional setup might be needed to ensure multi-arch builds are working. Specifically look here: https://medium.com/@artur.klauser/building-multi-architecture-docker-images-with-buildx-27d80f7e2408
