[ML] NP: migrate server by alvarezmelissa87 · Pull Request #58680 · elastic/kibana

alvarezmelissa87 · 2020-02-26T23:29:53Z

Summary

Migrate legacy server to NP.

Create server plugin/index for ml in x-pack/plugins
Move all legacy/server files to plugins/ml
Update all shared type/constants/etc imports in NP server to import from legacy/ (once client is fully moved over those import paths can be updated)

NOTES

x-pack/legacy/plugins/ml/public/application/license/check_license.tsx getFeatures has been hardcoded to return full permissions for now. This will be handled in a follow-up.

In the NP plugin license check, isAvailable is set to isEnabled for now as the NP license check returns false for isAvailable with a basic license - ML should be available on basic with very reduced functionality. This will also be sorted in the follow up.

I think it's ok to call getLicenseCheckResults again in here rather than caching the license object locally.
getLicenseCheckResults just returns the already created license results object and has no overhead.
job_service.ts is doing this without a cache also in this file on line 80.

all 'ml' strings in this file could be PLUGIN_ID from types.ts

Good call - added in 609be5c4c218d1feed4b249158c438ce7c30f99d

jgowdyelastic · 2020-02-27T09:02:50Z

x-pack/plugins/ml/server/types.ts

it'd be good to move this to common as we often need this string client side. it could go in app.ts.
(also API_BASE_PATH in there can go as it's a leftover from transforms being in ML)

this should have a type so we can use it in each route.

jgowdyelastic · 2020-02-27T09:35:06Z

x-pack/plugins/ml/server/plugin.ts

i wonder if it's worth merging these into a single object?
An alternative approach could be to pass the routeInit as a single first argument to each route, so they are all the same, and for the routes that require additional information, pass that as a second argument.
The routes themselves could then manage the type of that second "additional dependancies" parameter.
Something like:

systemRoutes(routeInit, { spacesPlugin: plugins.spaces, cloud: plugins.cloud, });

Good idea - used the second idea of having an 'additional dependencies' second parameter where applicable. 609be5c4c218d1feed4b249158c438ce7c30f99d

x-pack/plugins/ml/server/plugin.ts

This should include enterprise too, in line with the list of VALID_FULL_LICENSE_MODES in server/lib/check_license/check_license.ts. We should probably define that list of full license modes in e.g. common/constants/license.ts.

Updated and moved to constants/license.ts in 609be5c4c218d1feed4b249158c438ce7c30f99d

peteharverson · 2020-02-27T10:14:32Z

x-pack/plugins/ml/server/lib/check_license/check_license.ts

See other comment regarding moving this into a common constants file. Could be done in the follow-up to fix the licensing checks.

x-pack/plugins/ml/server/routes/anomaly_detectors.ts

Are all these commented out lines for the RouteInitialization needed in all the routes files?

RouteInitialization could be reused for my requested change.

peteharverson · 2020-02-27T10:58:06Z

Gave this a good test, and all works well, apart from the ML item with the Jobs List doesn't appear in the Management app. Is this related to the licensing work that needs to be done?

jgowdyelastic · 2020-02-27T11:13:41Z

x-pack/legacy/plugins/ml/index.ts

managementSections: ['plugins/ml/application/management'], on line 24 isn't registering our management section anymore.
Is there a NP equivalent?
(github wouldn't let me add this to line 24)

There is, but I think it should work. Maybe this this an issue with the fact that there is now both a x-pack/legacy/plugins/ml and x-pack/plugins/ml folders? But the NP ml plugin has no public part, so I'm not sure to understand. @elastic/kibana-app-arch would you mind to take a look?

@jgowdyelastic - looks like the issue is that in applicatoins/management the code to register the app in management is wrapped in an if block that relies on legacy xpackInfo.

The solution is to use the frontend licensing service - npSetup.plugins.licensing where npSetup comes from import { npSetup } from 'ui/new_platform'

Then we can can pull the relevant license info from

licensing.license$.subscribe(async license => { if (license.type && VALID_FULL_LICENSE_MODES.includes(license.type)) { ... <register management app>

Probably this same approached can be used in the work you'll be doing for check_license.tsx @jgowdyelastic 🤔

This file doesn't do anything in legacy. I would remove it completely.

Registering the management section can be addressed in a follow-up PR as we have to do follow up work for licensing issues as well.

This has been updated for all comments and is ready for final look cc @jgowdyelastic, @peteharverson, @joshdover

Tested and LGTM!
This PR is a cut (over) above the rest!
It certainly makes the cut (over)!
Sorry, yeah I know, I could cut (over) it out.

Not a huge concern, but you should unsubscribe from this observable in the stop phase.

Oh good catch - added to checklist 👍
