s6-overlay is a set of scripts and binaries that installs the s6 process supervisor as PID 1 inside Docker containers, along with execline and s6-linux-utils. It lets existing Docker images run multiple supervised services with proper init semantics, logging, and privilege dropping.

Use cases

• run multiple processes in a single docker container
• proper init system and zombie reaping for containers
• supervise and restart services inside a container
• drop privileges for services in docker images
• capture and route container service logs
• run initialization and finalization tasks at container startup and shutdown

When to choose

• your Docker image needs to run more than one process reliably
• you want proper signal handling and PID 1 behavior in containers
• you need per-service supervision, logging, and restart policies inside a container

When to avoid

• you follow the one-process-per-container pattern strictly
• you want a minimal image and can use a simpler init like tini
• you only need Kubernetes-managed multi-process pods
