Hosting MySQL and Mongo in Kubernetes globally #46
Description
Following what we did for ElasticSearch where we can enable a global instance shared across different installations in the same cluster, a similar solution can be explored for MySQL and Mongo.
Along with my teammates in Edunext, we explored options to run MySQL HA in Kubernetes and found interesting options:
- Percona XtraDB Cluster (PXC) for Kubernetes.
- InnoDB cluster for Kubernetes.
We focused on PXC and were able to connect a Percona cluster to a Palm Installation. This is still a proof of concept, however we think it's worth trying it out in the context of the harmony project.
NOTE: Percona offers a similar options for Mongo HA in Kubernetes
