As the Kubernetes ecosystem continues to grow, installing NATS via Helm has become a very popular method. The NATS 0.x series of the Helm Chart was initially released in 2020, a full year before JetStream was even available in the NATS Server. The past 3 years have taught us that it is important to support all of the extensibility options possible in Kubernetes resources - custom Image Registries, ConfigMaps, TLS Secrets, Volumes and Mounts, Init Containers, and more.
