Docker Swarm代码分析笔记（12）——container相关的config

创建和更新container时需要涉及到container的config（cluster\config.go）:

// ContainerConfig is exported
// TODO store affinities and constraints in their own fields
type ContainerConfig struct {
    container.Config
    HostConfig       container.HostConfig
    NetworkingConfig network.NetworkingConfig
}

// OldContainerConfig contains additional fields for backward compatibility
// This should be removed after we stop supporting API versions <= 1.8
type OldContainerConfig struct {
    ContainerConfig
    Memory     int64
    MemorySwap int64
    CPUShares  int64  `json:"CpuShares"`
    CPUSet     string `json:"Cpuset"`
}

其中container这个package定义在/vendor/github.com/docker/engine-api/types/container/config.go，container.Config包含不依赖于host的container的config；依赖于host的config定义在container.HostConfig；而container网络相关的config保存在network.NetworkingConfig。
