Whenever this guide refers to a host, we're talking about a virtual host supported by a wasmCloud host process. When you are looking at the infrastructure view of your constellation, you're looking at your constellation grouped by virtual host.
As you saw in the quick start guide, a host element looks something like the following:
Let's take a look at the various pieces of information here:
- Host (friendly) name - In this case, the friendly name is
mauve-sea-1703. You should not confuse this with a publicly accessible host (e.g. DNS) name. This is only provided as a convenience when distinguishing one host from another.
- Labels - You can supply an arbitrary set of key-value pairs to apply to any given host. Some fields, like those beginning with
hostcore.will always be set on hosts. You may also see some values supplied by Cosmonic if the host was started in our infrastructure as opposed to yours.
- Entities - The entities section indicates the number of actors and providers currently running within this host. If you click on the host element on the canvas to bring up the detail panel on the right, you'll be able to see the names and keys of each of those entities.
- Key - Clicking the cliboard icon here will copy the host's 56-character public key to your clipboard. This key can be used in a number of operations and is particularly helpful when you want to run CLI commands.
