I use OAuth2 Proxy in my Kubernetes clusters to secure frontends like Prometheus, Alertmanager, and other internal tools. This allows me to use my personal GitLab instance to act as a central identity provider, reducing the number of passwords needed to be maintained. Recently, I wanted to allow secure, programmatic access to Alertmanager between multiple Kubernetes clusters.
