Spring-boot-admin: Support for Spring Boot 2.0.0

[micheljung]

Spring Boot 2.0.0 is going to be released soon.

See PR #466

[anderius]

@joshiste: Is there any news about Spring Boot 2 support? Do you await the final release, or is there a snapshot somewhere? I would be happy to start testing if you have a branch somewhere! :-)

[wtatum]

I'd also be happy to do some testing against a snapshot release of 2.0.0. We're already using Boot 2.0.0 since we're not planning to go to production until well after the planned December 18 release of Boot 2.

[joshiste]

the master will switch to boot 2.0 when rc1 of it is published
.

[wtatum]

Thanks for the update @joshiste . I had that feeling from other threads but couldn't find anything official.

[n0mer]

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0.0-RC1-Release-Notes release notes for RC1 are available, although it is not yet relased (as per https://github.com/spring-projects/spring-boot/releases )

[joshiste]

Due date for the spring boot RC1 is January 25...

[joshiste]

[friddle]

great！

[perdonare]

ui related module not in the snapshot repository

[joshiste]

spring-boot-admin-server-ui is in there. What are you missing?

[n0mer]

@joshiste Could not find de.codecentric:spring-boot-admin-server-ui-activiti:2.0.0-SNAPSHOT

https://oss.sonatype.org/content/repositories/snapshots/de/codecentric/spring-boot-admin-server-ui-activiti/ - latest is 1.5.8-SNAPSHOT (same for hystrix, login and turbine)

[n0mer]

@joshiste can you please elaborate how to use spring-boot-admin-starter-client for spring-boot 2.0.RC1? Client stopped working after updating to 2.0.0-SNAPSHOT

I'm using

spring:
  boot.admin:
    discovery.enabled: false
    period: 30000
    url: "https://sba.domain.tld"
    username: "user"
    password: "password"
    autoDeregistration: true
    client:
      service-url: "http://${spring.application.name}.domain.tld:${management.port}"
      management-url: "${spring.boot.admin.client.service-url}${management.context-path}"

[firegnome]

@n0mer Try to use 2.0.0.RC1 instead of 2.0.0-SNAPSHOT for your spring-starter projects. I had troubles with this too.

[n0mer]

@firegnome

i have this

+--- de.codecentric:spring-boot-admin-starter-client: -> 2.0.0-SNAPSHOT

[firegnome]

@n0mer Is it working for you or not? You may also have to add the snapshot repository like i did for gradle:
repositories { maven { url "https://oss.sonatype.org/content/repositories/snapshots" } mavenCentral() jcenter() maven { url "https://repo.spring.io/snapshot" } maven { url "https://repo.spring.io/milestone" } }

[n0mer]

@firegnome unfortunately, not - it is not even trying to register

[firegnome]

@n0mer ah I guess I see your problem, its in the yml configuration you need to do this:
spring.boot.admin.client.url: http://localhost:8070

The url configuration should be under client. Don't ask my why but i did debug it.

[n0mer]

https://github.com/codecentric/spring-boot-admin/commit/e0b60b5d36655ee2cd06adf39ad603a2a6c4b2c0 - this changeset introduced ClientProperties, that are referenced in de.codecentric.boot.admin.client.config.SpringBootAdminClientAutoConfiguration

[n0mer]

boot-admin-server started working with this snippet in build.gradle:

    ext {
        springbootVersion = '2.0.0.RC1'
    }

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        if (details.requested.group  == 'org.springframework.boot') {
            details.useVersion springbootVersion
        }
    }
}

@firegnome thanks for pointing to spring.boot.admin.client.url!

[n0mer]

JIC: has to add compile 'org.springframework.boot:spring-boot-starter-web' , because spring-boot-admin-server 2.x uses spring-webflux (not using spring-web transitively), so my

management:
  server:
    servlet:
      context-path: "/management"

is taken into account on sba instance itself as well.

[joshiste]

@joshiste can you please elaborate how to use spring-boot-admin-starter-client for spring-boot 2.0.RC1? Client stopped working after updating to 2.0.0-SNAPSHOT

All properties for the client were moved to spring.boot.admin.client.* so your properties need to be moved.

[joshiste]

JIC: has to add compile 'org.springframework.boot:spring-boot-starter-web' , because spring-boot-admin-server 2.x uses spring-webflux (not using spring-web transitively), so my

Yes. We need the WebClient from webflux. So you know should explicitely choose the reactive or serlvet starter and choose. Currently both variants are supported on the admin server.

[joshiste]

p.s. sorry for the outdated docs. Any help appreciated :)

[joshiste]

p.s. ui-hystrix, ui-turbine and ui-activiti modules were removed...

Login is integrated into the ui module as I expect everyone to need it.

Currently only 5% of the core-ui downloads uses the uiactivitu as well - so I'm not planning on reimplementing this for 2.0
Around 25% is using the ui-hystrix so this on my to do list...

[firegnome]

Hi @joshiste you asked why 2.0.0-SNAPSHOT stopped working for us and why we are using 2.0.0.RC1. My problem was, that the method getWebserverId() was removed in the SNAPSHOT.

If you compare the javadoc you see that it was removed:
https://docs.spring.io/spring-boot/docs/2.0.0.BUILD-SNAPSHOT/api/org/springframework/boot/web/context/WebServerInitializedEvent.html

https://docs.spring.io/spring-boot/docs/2.0.0.RC1/api/org/springframework/boot/web/context/WebServerInitializedEvent.html

[joshiste]

@firegnome you have to use the BUILD-SNAPSHOT

afaik currently there is no cloud MS/RC based on boot.RC1 so we have to use the snapshot

[rahul-pharande]

@joshiste is there tentative date when RC will be available for spring-boot-admin

[joshiste]

no RCs just SNAPSHOTs.
oss sonatype has no milestone repos.

[joshiste]

The Finchley.RELEASE has been postponed to May 14.
:(

[joshiste]

The Finchley.RELEASE was postponed to June 13, 2018
😭

[joshiste]

I'll investigate if a release without the spring-cloud part is viable

[Hronom]

June 13 is near is spring-boot-admin will be released at the same time?

[joshiste]

[n0mer]

@joshiste are you going to support flowable https://github.com/flowable/flowable-engine/issues/816 ?

[joshiste]

@n0mer No. But with 2.0.2 we have support for custom ui modules. So it would be possible to write a community extension as standalone project.
