Check the Installed Dynatrace Operator Version on Kubernetes

[gurugogi]

Summary: This post provides the command used to check the Dynatrace Operator version deployed in Kubernetes. It explains where the version information resides and how to query it via kubectl.

Hi All,

Please let me know whether there is any kubectl command to check the Dynatrace operator version installed on the k8s cluster. I know we can check it from DT UI (from kubernetes UI or from Host->Properties UI), but I want it to fetch from the command line to automate the operator upgrade process.

Please guide, thanks.

kubectl exec deploy/dynatrace-operator -n dynatrace -- dynatrace-operator troubleshoot

The troubleshoot option reveals the version. There might be a simpler method to obtain it.

@PacoPorro  thanks for your reply. I know this command output has operator version, but I was checking whether we can modify this command so that it shows only operator version.

kubectl exec -n dynatrace deployment/dynatrace-operator -- dynatrace-operator support-archive --stdout > operator-support-archive.zip

[support-archive] dynatrace-operator {"version": "v0.11.0", "gitCommit": "...", "buildDate": "...", "goVersion": "...", "platform": "linux/amd64"}

If you are after only the operator version you can try the below

kubectl get deployment dynatrace-operator -n dynatrace -o jsonpath='{.metadata.labels.app\.kubernetes\.io/version}'

@p_devulapalli  thanks for reply, its working, its printing % also at the end, need to check how I can remove this % from output.
kubectl get deployment dynatrace-operator -n dynatrace -o jsonpath='{.metadata.labels.app\.kubernetes\.io/version}' 1.0.0%

It should not be adding any % , may be a issue with prompt/formatting. Can you please try the below, it should output to next line clearly  

kubectl get deployment dynatrace-operator -n dynatrace -o jsonpath='{.metadata.labels.app\.kubernetes\.io/version}{"\n"}'

@p_devulapalli  this has eliminated %, thank you very much.
kubectl get deployment dynatrace-operator -n dynatrace -o jsonpath='{.metadata.labels.app\.kubernetes\.io/version}{"\n"}'
