## Pods created via HTTP
Kubelet periodically downloads a file specified by `--manifest-url=<URL>` argument and interprets it as a json/yaml file with a pod definition. It works the same as `--config=<directory>`, i.e. it's reloaded every now and then and changes are applied to running static pods (see below).

## Behavior of static pods
When kubelet starts, it automatically starts all pods defined in directory specified in `--config=` or `--manifest-url=` arguments, i.e. our static-web. (It may take some time to pull nginx image, be patient…):
