Pre-requisites:
|
|
1) have SeaweedFS master and volume servers running
|
|
2) have a "weed filer" running
|
|
These 2 requirements can be achieved with one command "weed server -filer=true"
|
|
|
|
This uses github.com/seaweedfs/fuse, which enables writing FUSE file systems on
|
|
Linux, and OS X.
|
|
|
|
On OS X, it requires OSXFUSE (http://osxfuse.github.com/).
|
|
|
|
If the SeaweedFS system runs in a container cluster, e.g. managed by kubernetes or docker compose,
|
|
the volume servers are not accessible by their own ip addresses.
|
|
In "outsideContainerClusterMode", the mount will use the filer ip address instead, assuming:
|
|
* All volume server containers are accessible through the same hostname or IP address as the filer.
|
|
* All volume server container ports are open external to the cluster.
