The test assumes that all nodes have Ceph client utilities installed.
Ceph RBD container is hand crafted to be really minimal. It creates a new RBD
on startup, which can take up to several minutes on busy machines.
iSCSI and RBD volumes don't work as Kubernetes services - these protocols
are broken by S-NAT created by kube-proxy - at least iSCSI exhanges real
IP address of the iSCSI target as part of the protocol.
This reverts commit 118004c166.
This helps with routing of TCP traffic between clients and servers in case
flannel or similar service is not installed and pods don't see each other.
- It needs 'insecure' in /etc/exports to allow NFS clients on ports > 1024,
Kubernetes service will change client port to a random number.
- glusterfs no longer needs explicit endpoint definition, it uses the service
instead.
- add appropriate server containers into contrib/for-tests/volumes-tester
- the tests are off by default (they need kubelet --allow_privileged=True)
- enable by 'go run hack/e2e.go ... --ginkgo.focus=Volume'
- add glusterfs tools to list of installed packages on each node
