UnverifiedThe entire system of this solution runs completely on Docker containers, with the n8n service and the Postgres database each running in separate containers.72% similarUnverifiedWhen Dify runs inside a Docker container, localhost points to the interior of the container; the host machine's LAN IP or host.docker.internal (available on macOS/Windows) must be used to access the Ollama service on the host machine.65% similarUnverifiedDify's eight containers are uniformly orchestrated via Docker Compose and communicate with each other through an internal network; an incorrect component startup order or port mapping will cause the entire service to fail to run.64% similarUnverified容器技术依赖Linux内核的namespace和cgroup机制实现进程隔离，所有容器共享同一宿主内核63% similarUnverifiedIn Kubernetes, kubelet calls the container runtime (such as containerd), which creates the container process via runc, potentially going through a pause container to maintain the Pod's network namespace.63% similar
