* e2e/csi: wait longer for plugins to become healthy
Plugins are Docker containers, and as such sometimes we get delays in startup
due to pulling from the registry and this is a source of test flakiness. Give
the plugins a little longer to start up.
* e2e/csi: version bump for AWS EBS plugins
Assert that deregistering a volume works without errors following a volume
reap. Use CLI helpers where feasible to exercise CSI command line. Dump plugin
allocation logs on deregistration failures for debugging purposes.
Controller plugins that land on the same node will collide over their CSI
`mount_dir`, so give them enough room in our tests that they don't land on the
same host.
Also, version bump the EBS node plugins to match the controllers.
This changeset provides two basic e2e tests for CSI plugins targeting
common AWS use cases.
The EBS test launches the EBS plugin (controller + nodes) and registers
an EBS volume as a Nomad CSI volume. We deploy a job that writes to
the volume, stop that job, and reuse the volume for another job which
should be able to read the data written by the first job.
The EFS test launches the EFS plugin (nodes-only) and registers an EFS
volume as a Nomad CSI volume. We deploy a job that writes to the
volume, stop that job, and reuse the volume for another job which
should be able to read the data written by the first job.
The writer jobs mount the CSI volume at a location within the alloc
dir.
