AEROGEAR-9985 - Upgrade mss-operator to operator-sdk v0.10.0

[aliok]

Verification instructions:

Enable anyuid:

minishift addons enable anyuid
minishift addons apply anyuid

Install Integreatly application monitoring operator:

clone https://github.com/integr8ly/application-monitoring-operator/ under your GOPATH.
make cluster/install

If you see an error in Prometheus regarding file system permissions, you need to chmod 777 the host path:

oc get pvc
oc get pv pv0058 -o yaml
# host path is /var/lib/minishift/base/openshift.local.pv/pv0058
minishift ssh
sudo chmod -R 777 /var/lib/minishift/base/openshift.local.pv/pv0058
exit
# delete prometheus pod to have the statefulset recreate it

Deploy MSS operator, monitoring for it, and an example app

# first, change image in operator.yaml to aliok/mss_opr_oct_1_1337
make install
make monitoring/install
oc project mobile-security-service-apps
make example-app/apply

Check these:

1. MSS is running, you can see the example app in MSS console
2. You can see MSS operator and MSS service in Prometheus targets
3. You can see MSS operator and MSS service related rules in Prometheus rules
4. You can see MSS operator and MSS service related dashboards in Grafana

Note that some of the stuff in Prom/Grafana doesn't show up properly in Minishift. I assume they will show up in RHMI cluster as these Prom queries came all the way until today.

@grdryn @psturc @laurafitzgerald
Ready for review now

[grdryn]

@psturc Do you know what version of Go is installed in the Jenkins agent that compiles?

[aliok]

@grdryn
Things were failing badly with the SDK with that version of Golang. Some dependency required Golang 1.12.

@psturc Can we update Golang version in Jenkins, if it is old?

[psturc]

the version of go in Jenkins slave is v1.12.6

[aliok]

Cool, should be no problems then!

[grdryn]

What was the significance of this being here originally, and is it good that it's being removed now?

[aliok]

From Go 1.1.2 release notes (https://golang.org/doc/go1.12)

The build cache is now required as a step toward eliminating $GOPATH/pkg. Setting the environment variable GOCACHE=off will cause go commands that write to the cache to fail.

I had to remove this parameter to make things working with Go 1.12

[laurafitzgerald]

Looks good to me. @grdryn are you doing the verification? If you want me to do it just ping me here.

[grdryn]

I haven't done any verification yet, I will though 👍

[grdryn]

@aliok along with the other comments I left in my original review, could you also add a stage like the following to the Jenkinsfile, so that we're using the correct version of the operator-sdk CLI there: https://github.com/aerogear/unifiedpush-operator/blob/master/Jenkinsfile#L61..L73

[grdryn]

I have verified this now. I believe at least my previous review comment about wrapping the creation of the servicemonitor should be addressed, since otherwise local development is a little broken.

[aliok]

All comments addressed now.
Merging!
