Network Segmentation.
Implement network isolation techniques (configure iptables rules). Network segmentation allows you to isolate containers, control access, and protect sensitive workloads. Even if a container is compromised, the attacker's actions will be limited to that specific container, while the entire system remains protected.
Avoid Network Subnet Overlapping.
Prevent connection issues by ensuring your Docker network subnets do not overlap. You can inspect the current network configuration using the docker network inspect command.
Utilize DNS for Service Discovery.
Docker's internal DNS translates container names to IP addresses within a single network, significantly simplifying service discovery and internal communication.
Secure Communication.
Use encrypted overlay networks for confidential applications, especially when working across multiple Docker hosts. This ensures that your inter-container and inter-host communications remain private and protected.
Key recommendations:
- Implement robust network isolation
- Carefully manage network configurations
- Leverage Docker's built-in DNS capabilities
- Prioritize secure, encrypted communications
