Constants ¶
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
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.
Variables ¶

// Timeout (optional) is the timeout (in seconds) to wait for the container
// to stop gracefully before forcibly terminating it with SIGKILL.
//
// - Use nil to use the default timeout (10 seconds).
// - Use '-1' to wait indefinitely.
// - Use '0' to not wait for the container to exit gracefully, and
// immediately proceeds to forcibly terminating the container.
// - Other positive values are used as timeout (in seconds).

WaitCondition is a type used to specify a container state for which to wait.
const ( WaitConditionNotRunning WaitCondition = "not-running" WaitConditionNextExit WaitCondition = "next-exit" WaitConditionRemoved WaitCondition = "removed" )
Possible WaitCondition Values.
WaitConditionNotRunning (default) is used to wait for any of the non-running states: "created", "exited", "dead", "removing", or "removed".
WaitConditionNextExit is used to wait for the next time the state changes to a non-running state. If the state is currently "created" or "exited", this would cause Wait() to block until either the container runs and exits or is removed.
WaitConditionRemoved is used to wait for the container to be removed.
