Azure Kubernetes Service

Question 1

What is a Container constructed of?

Answer 1

A set of file system Layers constructed using the following:

1, Base layer: A container image starts with a base layer, which is usually a minimal root filesystem.

2, Additional layers: Each subsequent layer represents a set of changes to the filesystem, such as adding, modifying, or deleting files and directories.

3. Read-only layers: These layers are stacked on each other in a read-only manner. Each layer only contains the changes from the previous layer.
4. Union filesystem: When a container runs, these layers are combined using a union filesystem to create a single, coherent filesystem view.
5. Copy-on-write: When a running container needs to modify a file, it uses a copy-on-write mechanism to create a new, writable layer on top of the read-only layers.
