    * Die Schlüssel dieses `dict` sind vom Typ `str` (z. B. die Namen der einzelnen Artikel).
    * Die Werte dieses `dict` sind vom Typ `float` (z. B. der Preis jedes Artikels).

### Tab blocks

There are special blocks surrounded by four slashes («////»). They mark text, which will be rendered as part of a tab in the final document. The scheme is:

policy for _all_ pods in the namespace: ``` kubectl annotate namespace default "net.beta.kubernetes.io/network-policy={\"ingress\":{\"isolation\":\"DefaultDeny\"}}" ``` With NetworkPolicy enabled, traffic will be limited to just port 9000. For more precise policy, set `networkPolicy.allowExternal=true`. This will only allow pods with the generated client label to connect to MinIO. This label will be displayed in the output of a successful install. Existing secret ---------- Instead of having this chart...
