Save, Load and Transfer Docker Image
🐳 Docker Level 3 - Day 4: Save, Load & Transfer Docker Images | Docker Series
Welcome to Day 4 of the Docker Level 3 Series! In this lab, you'll learn how to export Docker images, transfer them between servers, and import them on another host without using a container registry.
📌 Lab Objective:
Save a custom Docker image as an archive, transfer it to another server, and load it while preserving the original image name and tag.
🛠️ Task Requirements:
Source Server:
🔹 App Server 1 (stapp01)
Docker Image:
🔹 games
Tasks:
🔹 Save the image into an archive
🔹 Transfer the archive to App Server 3
🔹 Load the image on the destination server
🔹 Preserve the original image name and tag
Destination Server:
🔹 App Server 3 (stapp03)
Prerequisite:
🔹 Ensure Docker service is running on both servers
💻 What You’ll Configure & Verify:
🔹 Export Docker images
🔹 Create image archives using Docker
🔹 Transfer image files between servers
🔹 Import Docker images on another host
🔹 Verify image availability after loading
🔹 Preserve image tags and metadata
🔹 Validate successful image migration
🔹 Inspect Docker image inventories
📚 What You’ll Learn:
Docker Image Management
docker save
docker load
Image Portability
Docker Archives
Image Migration
Container Distribution
DevOps Operations
Infrastructure Automation
🌟 Why This Lab Matters:
In secure environments and private infrastructures, direct access to Docker registries may not be available. Knowing how to save, transfer, and load Docker images manually is an essential skill for deployments, migrations, backups, and disaster recovery scenarios.
