Added chaos monkey setup

[marcingrzejszczak]

fixes #174

I propose to mention this readme and this feature in the root readme file.
Could you also explain how use both shell scripts call_chaos.sh and run_all.sh shell scripts, what they do and how to exploit their results (maybe in grafana ?).

Sure! Just FYI I had to create run_all.sh which essentially just doesn't use docker to run everything. That's because I wasn't able to run this in docker :) I will update the readme though

In prevision of next Spring Boot version upgrade, do you know how to handle them the spring boot chaos monkey library?

[marcingrzejszczak]

That's what they write on their website (https://codecentric.github.io/chaos-monkey-spring-boot/#docs)

  | Chaos Monkey 1.0.1 | Chaos Monkey 1.5.0 | Chaos Monkey 2.0.0 | Chaos Monkey 2.0.1 | Chaos Monkey 2.0.2 | Chaos Monkey 2.1.1 | Chaos Monkey 2.2+
-- | -- | -- | -- | -- | -- | -- | --
Spring Boot 1.5.0 - 1.5.19 | no | yes | no | no | no | no | no
Spring Boot 2.0.0 - 2.0.8 | yes | no | yes | yes | yes | yes | yes
Spring Boot 2.1.0+ | no | no | no | no | yes | yes | yes

Ok thank you. So there is not one version of Chaos Monkey per version of Spring Boot. It will be easier for upgrades.

[marcingrzejszczak]

I've added some additional docs. WDYT?

[arey]

Thank you guys for your work.
I hope we will see you soon for future improvements :)

After having started the app with the run_all.sh script, I've got the following error when I'm testing the call_chaos.sh script:

arey@MacBook spring-petclinic-microservices % ./scripts/chaos/call_chaos.sh visits attacks_enable_exception watcher_enable_restcontroller
curl: (22) The requested URL returned error: 404

I'm seeing the Chaos Monkey banner into the starter logs:

The chaosmonkey actuator is not visible. Maybe a lead?
Do you have add some configuration in the spring-petclinic-microservices-config project?

[marcingrzejszczak]

Yes I have - spring-petclinic/spring-petclinic-microservices-config#14
