Constants

View Source 
const (
	NoHealthcheck = "none"      // Indicates there is no healthcheck
	Starting      = "starting"  // Starting indicates that the container is not yet ready
	Healthy       = "healthy"   // Healthy indicates that the container is running correctly
	Unhealthy     = "unhealthy" // Unhealthy indicates that the container has a problem
)

Health states

View Source 
const MinimumDuration = 1 * time.Millisecond

MinimumDuration puts a minimum on user configured duration. This is to prevent API error on time unit. For example, API may set 3 as healthcheck interval with intention of 3 seconds, but Docker interprets it as 3 nanoseconds.

Functions

func ValidateRestartPolicy 

func ValidateRestartPolicy(policy RestartPolicy) error

ValidateRestartPolicy validates the given RestartPolicy.

Types

type BlkioStats 

type BlkioStats struct {

TODO(thaJeztah): combine ContainerJSONBase and InspectResponse into a single struct.

ContainerJSONBase contained all fields for API < 1.19, and InspectResponse held fields that were added in API 1.19 and up. Given that the minimum supported API version is now 1.24, we no longer use the separate type.
