![]() > We don't want to apply a new Policy with imagePullPolicy set to Always because this would already fetch the latest version of the Pod, I would like to understand a little more about this statement Welcome to stack Overflow, related to where images are cached, as explained by Maze and above it depends on your OCI. If you do this, you shouldn't need to adjust imagePullPolicy: from its default or try to manually remove images from nodes. Your CI/CD system should cooperate with this, and assign a distinct tag to each image build (maybe based on the commit ID or a date stamp). Each node in turn knows how to garbage collect images not currently in use, though old images will generally stick around until the local disk fills up (or until a tool like the cluster autoscaler deletes the node).Ī general assumption in Kubernetes is that a given /name/image:tag string uniquely identifies an image. ( imagePullPolicy: Always skips the first step and always pulls the image Never skips the pull, and will fail if the image isn't already there.)Įach node will have its own copy of the images where exactly depends on the specific container runtime in use. ![]() If the image isn't already there, docker pull it.If you imagined Kubernetes was running Docker, it'd do the equivalent of:
