@@ -4,7 +4,7 @@ Kubespray supports several download/upload modes. The default is:
* Each node downloads binaries and container images on its own, which is ``download_run_once: False``.
* For K8s apps, pull policy is ``k8s_image_pull_policy: IfNotPresent``.
* For system managed containers, like kubelet or etcd, pull policy is ``download_always_pull: False``, which is pull if only the wanted repo and tag/sha256 digest differs from that the host has.

Container images and binary files are described by the vars like ``foo_version``,
``foo_download_url``, ``foo_checksum`` for binaries and ``foo_image_repo``,
``foo_image_tag`` or optional ``foo_digest_checksum`` for containers.
``foo_image_tag`` for containers.
Container images may be defined by its repo and tag, for example:
`andyshinn/dnsmasq:2.72`. Or by repo and tag and sha256 digest:
`andyshinn/dnsmasq@sha256:7c883354f6ea9876d176fe1d30132515478b2859d6fc0cbf9223ffdc09168193`.
Note, the SHA256 digest and the image tag must be both specified and correspond
to each other. The given example above is represented by the following vars:
```yaml
dnsmasq_digest_checksum: 7c883354f6ea9876d176fe1d30132515478b2859d6fc0cbf9223ffdc09168193
