REST API Overview

2. Prism/ Prism
Central nCLI
Nutanix REST
API
PowerShell
Cmdlets
API Underneath Everything
üAll platform config exposed via
well defined APIs
üAPI use tested heavily by internal
components
üBundled with Nutanix binary
Configure and manage Nutanix
clusters using multiple interfaces

3. Access REST API
• Login to Prism
• Click drop button next to admin
• Click on “REST API Explorer”

4. Entities Explorer Page
Click on show to
get list of possible
operations

5. Entity Operations

6. REST API Methods
• Currently REST API can be used using any HTTP request
• REST API explorer plugin with browser to draft custom HTTP
requests or utility like CURL or ARC for Chrome
• Structure of HTTP URL :
https://<PrismIP:PORT>/PrismGateway/services/rest/v1/<entity>
• Entity can be any Nutanix object like storage pool, container etc.
• Entity Operations:
• GET - is a read only option to check value of an entity
• POST - to add an entity (e.g. to add a container)
• PUT - to modify value of an entity (e.g. to update name of a
container)
• DELETE - to delete an entity

7. Example list of possible operations for an entity
Click on GET to expand Menu Bar
User can provide
various options to
filter output or
customize the
request
Click on “TRY it out!” to check output

8. Example output

9. Example: GET VMs
Possible operations with GET to filter output:
• Count: Provide number of container objects desired
• Page: with Paginated output which page is desired
• filterCriteria : to filter output e.g.
filterCriteria=power_state==off : will display
• sortCriteria : Use attribute with which you want to sort the output
• searchString: to search for any value in output

10. Example : to List alerts, events related to VM
To get attributes of a particular vm provide its vmID

11. Example : to List attributes of a particular VM

12. Example: POST and DELETE Container
Possible operations with POST to create output:
• Value: What is going to be created
• Model / Model Schema: Assist in inserting values
• Name and Storage Pool
After Creation
• Use GET to obtain Container ID
• Or HTTP URL
• Use DELETE to delete it

13. Example: How to create a container using POST
Name and StoragePoolID are mandatory parameters

14. Example: How to create a container using POST
As discussed it can be achieved via a REST client as well
