![]() IfNotPresentthe image is pulled only if it is not already present locally.Alwaysevery time the kubelet launches a container, the kubelet queries the container image registry to resolve the name to an image digest. Here’s a list of the values you can set for imagePullPolicy and the effects these values have: The imagePullPolicy for a container and the tag of the image affect when the kubelet attempts to pull (download) the specified image. This policy causes the kubelet to skip pulling an image if it already exists. When you first create a Deployment, StatefulSet, Pod, or other object that includes a Pod template, then by default the pull policy of all containers in that pod will be set to IfNotPresent if it is not explicitly specified. ) inside an image tag.If you don’t specify a tag, Kubernetes assumes you mean the tag latest. Image tags consist of lowercase and uppercase letters, digits, underscores (_), periods (.), and dashes (-).There are additional rules about where you can place the separator characters (_, -, and. Tags let you identify different versions of the same series of images. If you don’t specify a registry hostname, Kubernetes assumes that you mean the Docker public registry.Īfter the image name part you can add a tag (in the same way you would when using with commands like docker or podman). Images can also include a registry hostname for example: /imagename, and possibly a port number as well for example: :10443/imagename. ![]()
