Ensure that HEALTHCHECK instructions have been added to container images

BajaNivel 1Automatizadadocker

Descripción

A HEALTHCHECK lets the engine detect and report unhealthy containers. Flags running containers whose configuration (inherited from the image) has no healthcheck. The audit inspects every running container (docker ps -q) and prints the offending names; a host with no running containers is compliant.

Cómo se verifica

Método de auditoría: Comando de shell

shell

ids=$(docker ps -q) || exit 1; [ -z "$ids" ] && { echo compliant; exit 0; }; out=$(docker inspect --format '{{.Name}}{{if .Config.Healthcheck}} yes{{end}}' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk 'NF<2 {print $1}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Add a HEALTHCHECK instruction to the Dockerfile (or --health-cmd at run time) and rebuild the image.
