ContainerSSH: SSH Into Ephemeral Containers

by Shriira Press

ContainerSSH is a CNCF Sandbox project that reimagines what happens when you type ssh. Instead of dropping you onto a shared machine, it launches a brand-new container — in Kubernetes, Docker, or Podman — for that single connection, places you inside it transparently, and destroys it when you disconnect. Authentication and configuration are answered live by webhooks you control, so each user can land in a different image, backend, and environment. This book follows a connection end to end through ContainerSSH's four-step flow, covers the authentication and authorization webhooks, the configuration server and per-user dynamic backends, the Docker, Kubernetes, and SSH-proxy backends, and full audit logging — closing with honeypots, lab platforms, and audited production access.
