Quick checking Hue's SQL Editor connections to Databases in Kubernetes

Let's see one way to quickly check why Hue can't connect to a SQL Database in the Kubernetes world. We previously documented how to run Hue in Kubernetes or Docker. The concept is to use the Database specific command shell on the command line to try to send some queries. Apache Hive is the Data Warehouse used as example (but this would work the same with psql, mysql, …) or any other Database Hue can connect to.…

Hue in Kubernetes

Let’s see how to automate the deployment further and run this into a container orchestration like Kubernetes.  We previously documented the Hue Docker image that provides the latest Hue web server into a “box”. Hue ships with a Helm chart to make it really easy to get started. Helm is a package manager for Kubernetes. More advanced, directly use the yaml config files. In a Shell, after installing Helm, just execute these three instructions to boot a live Hue with its database:…

Note If you are looking another warehouse than Hive, check out all the other connectors. There are two important concepts: Persistence: Hue needs an existing database with transactions like MySQL to support concurrent requests and also not lose the registered users, saved queries, sharing permissions… when the server gets stopped.…
