Types ¶
type CustomDeploymentStrategyParams ¶
type CustomDeploymentStrategyParams struct {
// Image specifies a Docker image which can carry out a deployment.
Image string `json:"image,omitempty"`
// Environment holds the environment which will be given to the container for Image.
Environment []kapi.EnvVar `json:"environment,omitempty"`
// Command is optional and overrides CMD in the container Image.
Command []string `json:"command,omitempty"`
}

type Deployment ¶
type Deployment struct {
kapi.TypeMeta `json:",inline"`
kapi.ObjectMeta `json:"metadata,omitempty"`
// Strategy describes how a deployment is executed.
Strategy DeploymentStrategy `json:"strategy,omitempty"`
// ControllerTemplate is the desired replication state the deployment works to materialize.
ControllerTemplate kapi.ReplicationControllerSpec `json:"controllerTemplate,omitempty"`
// Status is the execution status of the deployment.
Status DeploymentStatus `json:"status,omitempty"`
// Details captures the causes for the creation of this deployment resource.
// This could be based on a change made by the user to the deployment config
// or caused by an automatic trigger that was specified in the deployment config.
// Multiple triggers could have caused this deployment.
