One of the most important things a consumer of your charm (or library)
|
||||
needs to know is what set of functionality it provides. Which categories
|
||||
does it fit into? Which events do you listen to? Which libraries do you
|
||||
consume? Which ones do you export and how are they used?
|
||||
Get familiarise with [Charmed Operator Framework](https://juju.is/docs/sdk)
|
||||
and [Sunbeam documentation](sunbeam-docs).
|
||||
|
||||
cinder-k8s charm uses the ops_sunbeam library and extends
|
||||
OSBaseOperatorAPICharm from the library.
|
||||
|
||||
cinder-k8s charm consumes shared-db relation to connect to database,
|
||||
identity-service to register the service endpoints to keystone
|
||||
and ingress-internal/ingress-public relation to get exposed over
|
||||
internal and public networks.
|
||||
|
||||
## Intended use case
|
||||
|
||||
TEMPLATE-TODO:
|
||||
Why were these decisions made? What's the scope of your charm?
|
||||
cinder-k8s charm deploys and configures OpenStack Block storage service
|
||||
on a kubernetes based environment. It should be possible to use
|
||||
local storage or ceph based storage as backend.

## Description
|
||||
|
||||
TODO: Describe your charm in a few paragraphs of Markdown
|
||||
The cinder-k8s is an operator to manage the cinder service on a
|
||||
kubernetes based environment.
|
||||
|
||||
## Usage
|
||||
|
||||
TODO: Provide high-level usage, such as required config or relations
|
||||
### Deployment
|
||||
|
||||
cinder-k8s is deployed using below command:
|
||||
|
||||
juju deploy cinder-k8s cinder --trust
|
||||
|
||||
Now connect the cinder application to an existing database,
|
||||
amqp and keystone identity.
|
||||
|
||||
juju relate mysql:database cinder:shared-db
|
||||
juju relate rabbitmq:amqp cinder:amqp
|
||||
juju relate keystone:identity-service cinder:identity-service
|
||||
|
||||
### Configuration
|
||||
|
||||
This section covers common and/or important configuration options. See file
|
||||
`config.yaml` for the full list of options, along with their descriptions and
|
||||
default values. See the [Juju documentation][juju-docs-config-apps] for details
|
||||
on configuring applications.
|
||||
|
||||
### Actions
|
||||
|
||||
This section covers Juju [actions][juju-docs-actions] supported by the charm.
|
||||
Actions allow specific operations to be performed on a per-unit basis. To
|
||||
display action descriptions run `juju actions cinder`. If the charm is not
|
||||
deployed then see file `actions.yaml`.
|
||||
|
||||
## Relations
|
||||
|
||||
TODO: Provide any relations which are provided or required by your charm
|
||||
cinder-k8s requires the following relations:
|
||||
|
||||
`shared-db`: To connect to the database
|
||||
`amqp`: To connect to rabbitmq
|
||||
`identity-service`: To register endpoints in keystone
|
||||
`ingress-internal`: To expose service on underlying internal network
|
||||
`ingress-public`: To expose service on public network
|
||||
`storage-backend`: To connect to backend which exposes storage
|
||||
|
||||
## OCI Images
|
||||
|
||||
TODO: Include a link to the default image your charm uses
|
||||
The charm by default uses follwoing images:
|
||||
`docker.io/kolla/ubuntu-binary-cinder-api:xena`
|
||||
`docker.io/kolla/ubuntu-binary-cinder-scheduler:xena`
|
||||
|
||||
## Contributing

|
||||
on enhancements to this charm following best practice guidelines, and
|
||||
