Config contains the configuration data about a container. It should hold only portable information about the container. Here, "portable" means "independent from the host we are running on". Non-portable information *should* appear in HostConfig. All fields added to this struct must be marked `omitempty` to keep getting predictable hashes from the old `v1Compatibility` configuration. github.com/docker/docker/api/types/container/config.go

type HealthConfig

type HealthConfig struct {
	// Test is the test to perform to check that the container is healthy.
	// An empty slice means to inherit the default.
	// The options are:
	// {} : inherit healthcheck
	// {"NONE"} : disable healthcheck
	// {"CMD", args...} : exec arguments directly
	// {"CMD-SHELL", command} : run command with system's default shell
	Test []string `json:",omitempty"`

	// Zero means to inherit. Durations are expressed as integer nanoseconds.
	Interval time.Duration `json:",omitempty"` // Interval is the time to wait between checks.
	Timeout  time.Duration `json:",omitempty"` // Timeout is the time to wait before considering the check to have hung.

	// Retries is the number of consecutive failures needed to consider a container as unhealthy.
	// Zero means inherit.
	Retries int `json:",omitempty"`
}

HealthConfig holds configuration settings for the HEALTHCHECK feature. github.com/docker/docker/api/types/container/config.go
