Add Zuul support, and allow monitoring of all services from the Registry

[jdubois]

• Add Zuul support to the Registry, so it can route requests to microservices/gateways/monoliths. The URL would be in the form /services/{application-name}/api/management
• When Upgrade the front-end to Angular 2 #98 is done, have a full "Admin" menu, that uses an internal Zuul to access each microservice, gateway and monolith. Each "admin" entry will have a top drop-down list (like we have currently on Swagger for gateways), where the service can be selected.
• Make the "admin" menu optional on the gateways and monoliths (as they can be monitored with the Registry)

[PierreBesson]

Also we should be able to display instances metadata, that I implemented in : jhipster/generator-jhipster#5221

I have created a mockup for some ideas I have for the admin panel design.

Of course you will also need an overview screen. Sorry I don't have time to participate, good luck to the interns working on this.

I'm on the first task.

• Add Zuul support to the Registry, so it can route requests to microservices/gateways/monoliths. The URL would be in the form /services/{application-name}/api/management

[jdubois]

First task is done :-)

[JulienMrgrd]

I've commit the health page. All requests concerning instances are routed correctly.
Normally, i've checked that there is no warning concerning the back and the front. As I start on Angular 2, there are probably some improvements to apply.

By default, the Registry "instance" is selected. You can launch some gateway/microservices, refresh, etc...

Do you want a PR, or do you prefer that I continue to code on other pages (config, logs and metrics) now ?

EDIT : I will add more comments and javadoc on my code

EDIT 2 : Actual view

[PierreBesson]

@JulienMrgrd Do you force a reload when switching services ?

[JulienMrgrd]

No, but indeed, we must do it.
There is no error displayed or "down" tag actually.

[JulienMrgrd]

With this commit, we can see instances status.
And, as @PierreBesson has proposed, instances switching provoke a refresh of routes.
(and I've remove some warnings, again)

[PierreBesson]

@JulienMrgrd Also recently I added instance metadata about registered applications (version, profile, etc.). Can you display it somewhere, maybe in the main "Application" tab.

[JulienMrgrd]

It concerns this PR ? Fix for displaying Consul instances and metadata #5170

I finish on the metrics page, and after I'll add this ;)

[PierreBesson]

Yes, it's this one.

[JulienMrgrd]

It's done @PierreBesson ;)

Just a little problem with the badge's css, I don't know why.
Maybe an update in package.json ?

As @jdubois said about registry, when the entire Angular 2/4 migration (and this issue) will be finished, we should apply a good layer of design/UX-UI.

[PierreBesson]

@JulienMrgrd, Nice ! Don't worry about the alignment issue. It can be fixed later.

[JulienMrgrd]

Logs page OK. The last page, "configuration", is in progress...

We may have to found a solution to reduce the loading time of logs. It's a little bit slow :/

Note : As we work on same files, the PR #106 (by @g-boy05 and @heronakam) should be merge before mine.

[g-boy05]

ok we look with @heronakam on this

[deepu105]

I think you can try to add infinitescroll for logs Thanks & Regards, Deepu

About the instance selection, are you OK (@jhipster/registry-developers) with something like that ? :

A Dropdown menu, with all instances grouped by application. The item is blue when you hover it (no mouse on screenshots 🐭).

I'm working on a typeahead/search input to reduce the number of instances (always by thinking of a registry that can visualize a hundred of instances).
We could, for example, search by instance or app name.

EDIT : Or something like that : https://codepen.io/skywalkapps/full/YwRvyY/

[deepu105]

@JulienMrgrd yes that would be very nice. I myself didnt like our current pills/tab selector as its not salable. Please go ahead and PR it 👍

[JulienMrgrd]

The second task of this issue is now OK with the PR #120.

@JulienMrgrd I will showing your work on the registry tomorrow during my presentation in Rennes. It's just too good ! 🎉
Can you do a temporary branch on your fork that includes everything you've done until now. It needs to be ready for tomorrow 14h30.

[JulienMrgrd]

@PierreBesson My "monitoringServicesZuul" branch (on my fork) is up-to-date (Angular 4, zuul, routes in admin, and the dropdown).

https://github.com/JulienMrgrd/registry/tree/monitoringServicesZuul

[jdubois]

Closing as only the last point is missing, but we'll do this later (first we have a stable registry, then we remove the screens)
