Download the PVE API documentation (apidoc.js) from Proxmox and transform it so that the file can be imported in node.js
npm install pve-apidoc-converterThis package contains a version of PVE API documentation (apidoc.js) for import in node.js.
This file can be loaded in node as per this example for further use:
const apidoc = require('pve-apidoc-converter');
console.log(apidoc);You can regenerate is manually (see the scripts below). The file used is apidocmod.js in ./output/modified/apidocmod.js.
The documentation of Proxmox's PVE API is:
- distributed as a file apidoc.js in the product: /usr/share/pve-docs/api-viewer/apidoc.js
- The current API version is available from the API Viewer: https://pve.proxmox.com/pve-docs/api-viewer/
In addition, I would recommend reading:
In addition to the file, this package contains an analysis of their API file (see below in Observations).
Their API file can serve as a basis to generate schemas and/or API clients. In particular, it can serve as the source to feed LUMASERV's proxmox-ve-openapi. But, key limitations should be considered.
As at August 25, 2021:
-
Discussions to ship directly a Perl OpenAPI/Swagger module with the product has been discussed by folks in Dec 2020 : https://www.mail-archive.com/[email protected]/msg02244.html
-
Proxmox stated in a message of [Dec 2020 on its pve-devel mailing list]](https://www.mail-archive.com/[email protected]/msg02244.html) that "we're not 100% JSONSchema compatible".
In addition, their API is not versioned (making it product's version specific) !
This package has been used to generate an analysis of the Proxmox PVE API as per its documentation.
The script used was generate_report.js.
The output is available in report.txt.
As at 25.08.2021, the script detected in Proxmox's API:
- 4 HTTP methods: GET, POST, PUT and DELETE,
- 6 tags : cluster, nodes, storage, access, pools, version,
- 340 paths,
- 507 operations,
- 505 parameters properties. Sometimes parameters contain dashes or underscores or [n] (see below)
- 315 returns properties. Sometimes properties contain dashes or underscores or [n] (see below)
- The name of operations in children -> info -> names is unique: delete (15), read (12), update (13).
- Paths sometimes contain:
- dashes: e.g. /nodes/{node}/qemu/{vmid}/agent/get-host-name
- underscores: e.g. /nodes/{node}/qemu/{vmid}/move_disk
In addition, manual inspection of apidoc.js doesn't indicate HTTP response codes.
The report contains further details on the keys and parameters used in the API.
The maximum of n is specified in the description field. The current maximum found is 30, but it varies. Two examples:
"serial[n]" : {
"description" : "Create a serial device inside the VM (n is 0 to 3)",
"optional" : 1,
"pattern" : "(/dev/.+|socket)",
"type" : "string",
"verbose_description" : "Create a serial device inside the VM (n is 0 to 3), and pass through a\nhost serial device (i.e. /dev/ttyS0), or create a unix socket on the\nhost side (use 'qm terminal' to open a terminal connection).\n\nNOTE: If you pass through a host serial device, it is no longer possible to migrate such machines -\nuse with special care.\n\nCAUTION: Experimental! User reported problems with this option.\n"
},
scsi[n]" : {
"description" : "Use volume as SCSI hard disk or CD-ROM (n is 0 to 30). Use the special syntax STORAGE_ID:SIZE_IN_GiB to allocate a new volume.",
"format" : {
...
Proxmox's PVE API is a Rest API using the standard 4 verbs.
But, conversion to openAPI on the client side will be fragible since :
-
The API is not versioned
-
The name of operations provided by Proxmox PVE API (in children -> info -> names) alone cannot be relied upon to build API's as operationIDs in OpenAPI's sense as it is not unique.
-
The presence of the [n] in arguments requires to generate up to 30 parameters.
LUMASERV's proxmox-ve-openapi took the points 2 and 3 into consideration.
The OpenAPI specification requires a schema with unique OperationIDs.
The schema generated by LUMASERV's proxmox-ve-openapi is mostly valid.
My proposed operationID scheme would differ as :
- One could use the parameter's name directly without brackets, but with first letter capitalized, instead of the word 'Single' e.g. {node} -> Node instead of Single,
- Paths with dashes would be separated with the second word having its first letter capitalized. e.g: foo-read -> FooRead, instead of Fooread
npm run-script downloadnpm run-script modifyapidocnpm run-script testIt should print the apidoc object to console
npm run-script generatereportIt should create the file report.txt in output/reports. Warnings appear in console as well as indication that the report have been saved.
