## Understanding Ozone command shell
|
|
The most used command when working with Ozone is the Ozone command shell.
|
|
Ozone command shell gives a command shell interface to work against
|
|
Ozone.
|
|
|
|
The Ozone shell commands take the following format.
|
|
|
|
> _ozone sh object action url_
|
|
|
|
**ozone** script is used to invoke all Ozone sub-commands. The ozone shell is
|
|
invoked via ```sh``` command.
|
|
|
|
The object can be a volume, bucket or a key. The action is various verbs like
|
|
create, list, delete etc.
|
|
|
|
|
|
Ozone URL can point to a volume, bucket or keys in the following format:
|
|
|
|
_\[scheme\]\[server:port\]/volume/bucket/key_
|
|
|
|
|
|
Where,
|
|
|
|
1. Scheme - This should be `o3` which is the native RPC protocol to access
|
|
Ozone API. The usage of the schema is optional.
|
|
|
|
2. Server:Port - This is the address of the Ozone Manager. This can be server
|
|
only, in that case, the default port is used. If this value is omitted
|
|
then the defaults specified in the ozone-site.xml will be used for Ozone
|
|
Manager address.
|
|
|
|
Depending on the call, the volume/bucket/key names will be part of the URL.
|
|
Please see volume commands, bucket commands, and key commands section for more
|
|
detail.
|
|
|
|
## Invoking help
|
|
|
|
Ozone shell help can be invoked at _object_ level or at _action_ level.
|
|
For example:
|
|
|
|
{{< highlight bash >}}
|
|
ozone sh volume --help
|
|
{{< /highlight >}}
|
|
|
|
This will show all possible actions for volumes.
|
|
|
|
or it can be invoked to explain a specific action like
|
|
{{< highlight bash >}}
|
|
ozone sh volume create --help
|
|
{{< /highlight >}}
|
|
This command will give you command line options of the create command.
