Can docker containers be networked? Docker containers can be networked. For example, docker container cloud products are based on docker technology and have flexible network forms. They support Private Cloud, Shared IP Network and Exclusive IP Network, and support NAT gateway.

Flexible network, SDN/Load Balancer

Container Cloud supports SDN network. Users can add switches free of charge according to their needs, set up Private Cloud freely, and set up service clusters. Moreover, the operation is very simple. One click can complete the connection and disconnection between containers and switches.

In addition to SDN networks, Kubernetes Engine also supports NAT network management and service discovery. The former can help users greatly reduce network costs, while the latter can directly use hostname communication when DNS is enabled in Private Cloud. If the user chooses to connect multiple containers to a Private Cloud, the container cloud also supports free addition of Load Balancer and Layer 4/Layer 7 Load Balancer, i.e. tcp/udp/http/https and other protocols.

Cluster architecture, flexible upgrade

Stability and security have always been important requirements for cloud services for SMEs. The container cloud is built based on cluster servers and adopts distributed storage. Each data is reserved for 4 copies, which fully guarantees data security and reliability. In addition, it supports the deployment of security groups, filters and controls incoming and outgoing traffic, and supports port addition by range.

On the basis of stability and security, the container cloud is also optional on demand to support users 'elastic upgrade. Users can freely choose vCPU, memory, disk size, disk type and other configurations according to their needs. In the later use process, they can also gradually upgrade the container cloud configuration according to their needs to reduce resource waste and save operation and maintenance costs.
