One of the DevOps team members was working on to create a new custom docker image on App Server 1 in Stratos DC. He is done with his changes and image is saved on same server with name apps:nautilus. Recently a requirement has been raised by a team to use that image for testing, but the team wants to test the same on App Server 3. So we need to provide them that image on App Server 3 in Stratos DC.

a. On App Server 1 save the image apps:nautilus in an archive.
b. Transfer the image archive to App Server 3.
c. Load that image archive on App Server 3 with same name and tag which was used on App Server 1.

Note: Docker is already installed on both servers; however, if its service is down please make sure to start it.

Connect to App Server 1

ssh tony@stapp01 sudo -i 

Password for tony: Ir0nM@n

Verify the Image Exists

docker images | grep apps 

Output:

apps nautilus 4aa886374dbd About a minute ago 145MB 

The image apps:nautilus is present on App Server 1.

Save the Image to an Archive

docker save -o /tmp/apps_nautilus.tar apps:nautilus 

Verify the archive was created:

ls -lh /tmp/apps_nautilus.tar 

Output:

-rw------- 1 root root 150M Oct 27 11:27 /tmp/apps_nautilus.tar 

The archive is 150MB in size.

Transfer the Archive to App Server 3

scp /tmp/apps_nautilus.tar banner@stapp03:/tmp/ 

Transfer progress:

apps_nautilus.tar 100% 149MB 106.4MB/s 00:01 

The archive was transferred successfully to App Server 3.

Connect to App Server 3

Verify Docker Service is Running

systemctl status docker 

Output:

Ensure Docker starts on boot:

systemctl enable docker 

Verify the Archive on App Server 3

ls -lh /tmp/apps_nautilus.tar 

Output:

-rw------- 1 banner banner 150M Oct 27 11:28 /tmp/apps_nautilus.tar 

The archive is present on App Server 3.

Load the Image Archive

docker load -i /tmp/apps_nautilus.tar

The image layers were loaded successfully.

Alternative syntax:

docker load < /tmp/apps_nautilus.tar 

Output:

Loaded image: apps:nautilus 

Verify the Image on App Server 3

docker images | grep apps 

Output:
