How can I rename the docker image?
I am currently managing a dockerenvironment that consists of multiple containers. One of its critical components is deployed by using an image named “myapp: latest” however, due to a recent update I need to rename this image to “myapp:V2”. How can I rename this docker image without affecting the production deployment?
If you want to apply docker rename images then you can follow several steps:-
1. Tag the existing image by using the command
“ docker tag myapp:latest myapp:V2”
Thus above command will create a new tag for the same image ID as “myapp:latest”
2. Push the Renamed image to a registry
The second step after tagging the existing image is pushing the renamed image to a registry by using the command
“docker push my app:V2”
3. Test the renamed image
Ensure that the renamed image is working properly or not before making changes in production. You can check it by using the command
“docker run myapp:V2
4. Update the deployment configuration
After checking the work of the renamed image you can modify your deployment to reference the new image tag to “myapp:V2” instead of “myapp:latest”
5. Deploy the changes
In the end, you can deploy the updated configuration in your production related to the environment.
