Constants

View Source 
const ContainerIDPrefix = "docker://"
View Source 
const DefaultNamespace = Namespace("default")
View Source 
const MagicTestContainerID = "tilt-testcontainer"

A magic constant. If the docker client returns this constant, we always match even if the container doesn't have the correct image name.

const TiltRunIDLabel = "tilt-runid"

Functions

func ContainerIDFromContainerStatus

func FixContainerStatusImages added in v0.8.2 

func FixContainerStatusImages(pod *v1.Pod)

Kubernetes has a bug where the image ref in the container status can be wrong (though this does not mean the container is running unexpected code)

Repro steps: 1) Create an image and give it two different tags (A and B) 2) Deploy Pods with both A and B in the pod spec 3) The PodStatus will choose A or B for both pods.

More details here: https://github.com/kubernetes/kubernetes/issues/51017

For Tilt, it's pretty important that the image tag is correct (for matching purposes). To work around this bug, we change the image reference in ContainerStatus to match the ContainerSpec.

func IsContainerExited 

func IsContainerExited(pod v1.PodStatus, container v1.ContainerStatus) bool

If true, this means the container is gone and will never recover.

	ResourceVersion string
}

type JSONPath added in v0.7.11 

type JSONPath struct {
	// contains filtered or unexported fields
}

This is just a wrapper around k8s jsonpath, mostly because k8s jsonpath doesn't produce errors containing the problematic path (and as long as we're here, deal with some of its other annoyances, like taking a "name" that doesn't do anything, and having a separate "Parse" step to make an instance actually useful, and making you use an io.Writer, and wrapping string results in quotes)

	Obj runtime.Object
}

Iterate through the fields of a k8s entity and replace a image name with its digest.

policy: The pull policy to set on the replaced image. 

When working with a local k8s cluster, we want to set this to Never,
to ensure that k8s fails hard if the image is missing from docker.

Returns: the new entity, whether the image was replaced, and an error.

func InjectImagePullPolicy 

func InjectImagePullPolicy(entity K8sEntity, policy v1.PullPolicy) (K8sEntity, error)

Iterate through the fields of a k8s entity and replace the image pull policy on all images.

func InjectParallelPodManagementPolicy added in v0.10.0 

func InjectParallelPodManagementPolicy(entity K8sEntity) K8sEntity

By default, StatefulSets use OrderedPodManagement.

This is a bad policy for development. If the pod goes into a crash loop, the StatefulSet operator will get wedged and require manual invervention. See: https://github.com/windmilleng/tilt/issues/1962

Tilt should change all statefulsets to use a parallel policy.
