Final answer:
To include your DockerHub username when pushing an image, you need to tag the image with your username. In this case, you would use 'docker tag IISNano user1/IISNano' to tag the image as 'user1/IISNano'. The correct login command is 'docker login' and doesn't involve the image name.
Explanation:
In order to push an image to DockerHub and include your username, you would need to tag the image appropriately. Docker images on DockerHub follow a naming convention that includes the username. That is, they are named like 'username/name', where 'username' is your DockerHub username and 'name' is the image name.
In this case, your DockerHub username is 'user1' and the image you want to push is 'IISNano'. So you need to rename or tag the image from 'IISNano' to 'user1/IISNano'. Once this is done, you can then push the image to DockerHub successfully. The Docker command for this operation would be 'docker tag IISNano user1/IISNano'. This command effectively tags the specific image 'IISNano' as 'user1/IISNano'.
Before you can push images to DockerHub, you must authenticate your Docker client to the DockerHub servers. You can do this by using the 'docker login' command. It's important to note that this login command does not require the image name; it only requires your DockerHub username and password.
Please note that the options 'docker exec ______________add-credentials user1' and 'docker associate user1 IISNano' are not valid Docker commands and hence, they have not been used in the 1000 words answer. Also, 'docker login IISNano user1' is not a proper use of the 'docker login' command as it does not need the image name.
