The woodpecker charm deploy a testing tool that enables various action based performance tests to be performed.
config.yaml for the full list of options, along with their
descriptions and default values. The option,
pool-name, may be provided as a
default pool name for the bench tests.
We are assuming a pre-existing Ceph cluster.
To provide the testing host:
juju deploy cs:~openstack-charmers-next/woodpecker
Then add a relation to the ceph-mon application:
juju add-relation woodpecker:ceph-client ceph-mon:client
Snap on Ubuntu 20.04 (Focal)
In the bundle:
... code-block:: console
woodpecker: num_units: 1 series: focal resources: swift-bench: /path/to/swift-bench.snap
From command line:
:command:`juju attach-resource woodpecker swift-bench=/path/to/swift-bench.snap
This section covers Juju actions supported by the charm. Actions allow specific operations to be performed on a per-unit basis.
To display action descriptions run
