*

8. Install Docker on the Linux VM

Download PuTTY and use it to establish an SSH connection to your virtual machine.

Note: Download PuTTy from here: https://www.putty.org/

*

9. Go to your Linux VM in the Azure portal, copy its Public IP address, and paste it into PuTTY and click "Open" to start an SSH session with the Linux VM.

*

10. In the terminal, provide the username and password to log in to your Linux VM.

*

11. Update the package index by running the following command:

Copy Command: sudo apt-get update

*

12. Install the required packages to enable apt to use repositories over HTTPS by running:

Copy Command: sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

*

13. Add Docker’s official GPG key by running this command:

Copy Command: curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

*

14. Set up the stable Docker repository by running this command:

Copy Command: sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"

*

15. Update the package index and install Docker by running these commands:

Copy Command: sudo apt-get update

Copy Command: sudo apt-get install docker-ce docker-ce-cli containerd.io

*

16. Push Docker Image to Azure Container Registry.

To push an image to Azure Container Registry, you first need a Docker image. If you don’t have a local image, you can pull a public image from Docker Hub to get started.

In the Azure portal, navigate to your Container Registry. Under the Settings section on the left, select Access keys. Check the Admin user box to reveal the username and password needed to authenticate with your registry.

*

17. Return to your Linux VM session and run the following command to log in to your container registry. When prompted, enter the username and password you obtained earlier. Be sure to replace loginServer with your container registry’s login server name:

Copy Command: sudo docker login <loginServerrname>
