Instructions

• Create a myvars file that fits your environment. You can use the myvars.example as inspiration.
• Run the deploy.sh script

Run the deploy.sh script and validate the pods are inplace:

oc get po -n openshift-ptp
NAME                            READY   STATUS    RESTARTS   AGE
linuxptp-daemon-6xjnq           1/1     Running   0          18m
linuxptp-daemon-fkzxj           1/1     Running   0          18m
linuxptp-daemon-mtpn4           1/1     Running   0          18m
linuxptp-daemon-r7z5d           1/1     Running   0          18m
ptp-operator-7f4d4dddf4-v2xzc   1/1     Running   0          19m

Testing

Run the test.sh file. It will label one of the masters randomly to act as the grandmaster, then it will deploy the ptp config yaml files one for the grandmaster and one for the slaves.

Deploying unreleased versions

If you want to test a unreleased version of the PTP operator you need to add a new operator source. In case the operator source is private you will need to provide a secret with the login token.

Login token creation example:

apiVersion: v1
kind: Secret
metadata:
  name: marketplacesecret
  namespace: openshift-marketplace
type: Opaque
stringData:
    token: "<token>"

Then you can create the new operator source using the authorization token that was created before

apiVersion: "operators.coreos.com/v1"
kind: "OperatorSource"
metadata:
  name: "opsrctest"
  namespace: "openshift-marketplace"
  labels:
    opsrc-provider: opsrctest
spec:
  authorizationToken:
    secretName:  marketplacesecret
  type: appregistry
  endpoint: "<end-point>"
  registryNamespace: "<registry-namespace>"
  displayName: "opsrctest"
  publisher: "opsrctest"
