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.

Functions

func ContainerIDFromContainerStatus 

func ContainerIDFromContainerStatus(status v1.ContainerStatus) (container.ID, error)

func ContainerMatching

func FindImageRefMatching added in v0.2.0 

func FindImageRefMatching(pod v1.PodSpec, selector container.RefSelector) (reference.Named, error)

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.

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

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)

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