When I am trying to update the deployment by uploading an updated deployment.yaml, there is an error showing deployments.apps {my-app-name} already exists.
I know that I can update the image version from deployment, but I want to do all the work using yaml, so that I can keep track of what I am doing.
Thanks
p.s. I do not have console access to that machine, only the dashboard web interface.
Didn't find the other way as to update deployment through the Dashboard WEB UI submenu: Deployments > View/edit YAML.Seems that POST request within https://Web_ui_dashboard_IP/api/v1/appdeploymentfromfile does not support deployment modification.
please try following on command line :
kubectl apply -f deployment.yaml -n <namespace name>
To do this from dashboard by uploading the yaml file -
delete your existing deployment and upload the modified file. While your deployment is running, you cannot upload the file for the same deployment again.
