I’m running docker on Oracle Linux 7.9 VM. I’m using docker images from both private & public repository. I maintain private images in the docker hub. While deploying a service, it’s unable to automatically download images from the private repository. But able to auto-download images from public repository. If I manually download the private image and deploy the service, then service is coming up without any issues & working fine. But I don’t want to do manual work all the time.
It says ‘No such image’ error even though I’ve image in the docker hub. Provided docker login credentials is also correct. Adding my VM spec, syntax used and error logs below.
