Dear Raeders,
In this article,we will see Make Image to Private and Pull from Docker Hub then create container from the image.
Steps to Follow
- Logging to Docker Hub Account and make image to private (Graphically).
- Connect to Docker Linux EC2 Terminal through Putty.
- Switch to root user.
- Pull Image from Docker Hub.
- Logging to Docker Hub Account.
- Pull Image from Docker Hub.

- Create a container “ktexperts-new-container-1” from the above image “rameshktexperts/ktexperts-new-image”.
- Verify files inside the Directory “ktexperts”.
- Verify Container “ktexperts-new-container-1”.
1. Logging to Docker Hub Account and make image to private (Graphically)
Provide username and password and click n Sign in.
We can see the image “ktexperts-new-image” in your Docker Hub Repository.

By default docker images are public.
we can make it private also if required.
Click on PRIVATE.

Enter name of image “ktexperts-image” for confirmation and click on Make Private.
The image “ktexperts-image” has been made to private successfully.
