Building this thing

Creating the operator SDK structure

This follows the instructions in the operator SDK repo.

  • Make sure you have a recent version of go installed.

      plw@PC4003:~/work/go$ go version
  go version go1.13 linux/amd64

  • Install the operator-sdk binary and put on your path.

  • Ensure that GOPATH is set, and that GO111MODULE is set.

      export GO111MODULE=on

  • Create the project.

      mkdir -p $GOPATH/src/operator-sdk
  cd $GOPATH/src/operator-sdk
  operator-sdk new svcctl
  cd svcctl

Adding objects

  • Add an API object for a NetService, and a controller for that object.

      operator-sdk add api --api-version=svcctl.metaswitch.com/v1alpha1 --kind=NetService
  operator-sdk add controller --api-version=svcctl.metaswitch.com/v1alpha1 --kind=NetService

  • Copy in the two files from the [src](src} directory to replace these two files:

      $GOPATH/src/operator-sdk/svcctl/pkg/apis/svcctl/v1alpha1/netservice_types.go 
  $GOPATH/src/operator-sdk/svcctl/pkg/controller/netservice/netservice_controller.go

  • Every time you change anything in the CRD definition, update the APIs etc.

      operator-sdk generate k8s && operator-sdk generate openapi

  • To build the actual code (as opposed to CRDs) try this, where IMAGE should be a location you are allowed to push to:

      IMAGE=metaswitchglobal.azurecr.io/plw/svcctl-operator:latest
  operator-sdk build $IMAGE && docker push $IMAGE

  • You need to set that image in the operator YAML too.

      sed -i "s|image:.*|image: ${IMAGE}|" manifests/install/operator.yaml
