@jwilander I'm wondering if we should widen the definition a bit from NFS. It doesn't need to be specifically NFS(although that will be most common), but rather a network-mountable ReadWriteMany volume. Thoughts? |

@DSchalla we could but it may be better to be opinionated so it's less open ended for customers who are looking for recommendations. If they want to use another type of network storage they can ask us about it (or just use it if they know what they're doing) |

| Mattermost currently supports storing files on the local filesystem and Amazon S3 or S3-compatible containers. We have tested Mattermost with `MinIO <https://min.io/>`__ and `Digital Ocean Spaces <https://docs.digitalocean.com/products/spaces/>`__ products, but not all S3-compatible containers on the market. If you are looking to use other S3-compatible containers, we recommend completing your own testing. | ||

There was a problem hiding this comment.
Do we need to aggressively remove MinIO when we're keeping Digital Ocean Spaces? MinIO isn't going away, it's just not free anymore -- but Digital Ocean Spaces never was?
