The Hidden Life of a Container: A Complete Lifecycle
The article explores the lifecycle of a container, detailing its journey from creation to termination. It explains the underlying kernel processes involved at each stage and highlights common issues that can arise in production systems. By examining the components and operations of containers, the piece provides insight into their functionality and management.
- ▪Containers are built from images, which are stacks of read-only filesystem layers identified by SHA256 digest.
- ▪The process of running a container involves two distinct steps: docker create and docker start.
- ▪During the docker create phase, the environment for the container is allocated, including namespaces and cgroups.
