Actually, my bad - I didn't read your question carefully enough. You
wanted to access that annotation, but from inside a pod.
That can be done too. I've run scripts inside a pod that query the
kubernetes api server for information like that. I don't have a code
example for that handy, unfortunately, but it would be similar to my
previous response, and look something like this:
curl https://<kubernetes api>:443/api/... | jq -r
'.items[].metadata.annotations' | less
More details here:

You could then run it through a json parser to strip out what you want.
E.g.:
kubectl get deployment -o json | jq -r '.items[].metadata.annotations' |
less

Hi all,
I'm looking for some help with exposing annotations.
Each Deployment gets this annotation:
$ kubectl describe deployment/myapp
Name: myapp
Namespace: default
CreationTimestamp: Sat, 24 Mar 2018 23:27:42 +0100
Labels: app=myapp
Annotations: deployment.kubernetes.io/revision=5
Is there a way to read that annotation
(deployment.kubernetes.io/revision)
from a pod that belongs to the deployment?
I tried Downward API, but that only allows to expose annotations of
the *pod
itself* (not of its deployment).
