Docker Image Layers Explained (How Docker Images Actually Work)
Docker images power almost every container you run, but very few developers actually understand how they work.
In this video we break down Docker image layers and explain how Docker builds images, stores layers, and reuses them to make containers efficient.
You'll learn:
• What Docker images really contain
• How image layers work
• Why Docker images are so small
• How Docker reuses layers
• What happens when you build a Dockerfile
• How containers start from images
By the end of the video, you'll understand Docker images at a much deeper level and how this impacts container builds and performance.
