Function Engine API

Qinling Base URLs

All API calls through the rest of this document require authentication with the OpenStack Identity service. They also required a url that is extracted from the Identity token of type function-engine. This will be the root url that every call below will be added to build a full path.

Note that if using OpenStack Identity service API v2, url can be represented via adminURL, internalURL or publicURL in endpoint catalog. In Identity service API v3, url is represented with field interface including admin, internal and public.

For instance, if the url is http://my-qinling-url.org/qinling/v1 then the full API call for /functions is http://my-qinling-url.org/qinling/v1/functions.

Depending on the deployment the function engine url might be http or https, a custom port, a custom path, and include your project id. The only way to know the urls for your deployment is by using the service catalog. The containers service URL should never be hard coded in applications, even if they are only expected to work at a single site. It should always be discovered from the Identity token.

As such, for the rest of this document we will be using short hand where GET /functions really means GET {your_qinling_url}/functions.

Versions

Lists, creates, detaches, shows details and deletes versions.

Function versions are like git commits, they’re snapshots of your project history. Each version has a number that serves as its ID, starting with 1 and incrementing up, and never reused. The code for a published version of a function is immutable (i.e. cannot be changed). So, a version number corresponds to a specific set of function code with certainty.
