Understanding Docker-in-Docker Architecture: Is it Good or Bad?
Evaluating the usefulness, complexity and security trade-offs of nested Docker workflows in development and CI pipelines.
This is a concise portfolio reading guide to my published Medium article. For the complete original text, examples and diagrams, use the Medium link below.
Where it helps
The article considers isolated development environments and CI/CD build-and-test workflows.
Trade-offs
Nested workflows add resource overhead, operational complexity and security considerations.
An important distinction
The article also illustrates mounting the host Docker socket into a container; this provides access to the host daemon rather than creating a fully independent nested daemon.
