During the deployment of my application to Kubernetes, I come across with such kind of problem :

Waiting for deployment "yourapplication" rollout to finish: 0 of 1 updated 
replicas are available...
Waiting for deployment spec update to be observed...
Waiting for deployment "yourapplication" rollout to finish: 1 out of 2 new 
replicas have been updated...
Waiting for deployment "yourapplication" rollout to finish: 1 out of 2 new 
replicas have been updated...
Waiting for deployment "yourapplication" rollout to finish: 0 of 2 updated 
replicas are available...   

Also I get that error message as well :
