About this tool
Container Networking Reference
The Container Networking Reference covers Docker network modes, overlay network requirements, Kubernetes CNI plugins, service discovery DNS, and port publishing via iptables.
• Look up bridge vs host network mode before configuring a Docker Compose service
• Reference overlay network requirements before setting up a Docker Swarm cluster
• Find CNI plugin comparison before choosing networking for a new Kubernetes cluster
• Reference Docker Compose DNS service discovery before debugging name resolution

FAQ
What does this tool tell you?
The Container Networking Reference covers Docker network modes, overlay network requirements, Kubernetes CNI plugins, service discovery DNS, and port publishing via iptables.
What affects the result most?
Bridge network: default, isolated per-compose-project — containers share network, DNS by service name. Host network: shares host network namespace — no port publishing, full host network access. Overlay network: Docker Swarm and Kubernetes — spans multiple hosts, requires key-value store.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
