  # the version of the inventory store structure
  unique_hostname:
    # hostnames need to be unique in a cluster, we can use it as the key with values
    # being the attributes
    attributes:
      # here we store arbitrary information about the host like
      # fqdn, kernel version, os-name etc
      # this opens up the possibility for node inspection (cpu/ram consumption etc)

Workflow examples:

Note: The depicted workflow starts after the initial deployment with bin/cephadm.

Task 0:

Add available hosts to cephadm:

ceph orch host add host{1..20}

jschmid1

Proposal:

Make the CLI more `spec` centric.

`ceph orch spec <operation> <--service-type>|<--service-name>`


Examples:

`ceph orch spec ls`
