Running Elasticsearch on Kubernetes (Video)
A few weeks ago I gave a talk on Google Campus TLV on deploying and running Elasticsearch on Kubernetes - best practices and various gotchas. The video for the talk is below.
There is also a blog post with most of the technical details here.
On that note, you should definitely check out Elastic's recent announcement of Elastic Cloud on Kubernetes (ECK), which is an Elasticsearch Operator based on the Kubernetes Operator pattern. Read more about that here.
