3 or 4 years ago our companies customer seem to silently have agreed that their container strategies are soly based on kubernetes. Lately I have been buisy with crafting cloud based solutions and IaC/build, delivery and deployment chains.
If your storage demands do not require much capacity. I can highly recommend portworx with Swarm. The develop edition (px-developer is free and If i remember correctly support 1TB of storage. It basicly turns each node of your cluster to a storage node and handle replicas under the hood for you. The docker plugin is solid and the installation is a matter of minutes. It might resemble GlusterFS, but instead of beeing a storage cluster, Portworx is a cluster of storages 
The fun part is, It allows different different storage types (hd/ssd/nvme), different profile (general, db, and others I don’t remember) and creates one to one block devices for volumes or one to many nfs baked block devices for volumes.
