  channel:
    type: string
    default: auto
    description: "The snap channel from which to install etcd (e.g. '3.3/stable'), or 'auto'\nto accept the charm default. Choosing 'auto' will install the latest \nsupported version of etcd at deploy time, but will not automatically upgrade\nto a newer version thereafter.\n"
  heartbeat_interval:
    type: int
    default: 100

  election_timeout:
    type: int
    default: 1000
    description: |
      How long a follower node will go without hearing a heartbeat before
      attempting to become leader itself.
      By default, etcd uses a 1000ms election timeout.
  snapshot_count:
    type: string
    default: auto
    description: |
      Creating snapshots with the V2 backend can be expensive,
      so snapshots are only created after a given number of changes to etcd.
      The value could be an integer number or auto.
      if auto, the channel version is checked.
      Any channel grather than 3.2, use 100000 as value otherwhise 10000 is set
      If etcd’s memory usage and disk usage are too high,
      try lowering the snapshot threshold.
  snapd_refresh:
    default: "max"
    type: string
    description: |
      How often snapd handles updates for installed snaps. Set to an empty
      string to check 4x per day. Set to "max" (the default) to check once per
      month based on the charm deployment date. You may also set a custom
      string as described in the 'refresh.timer' section here:

  bind_with_insecure_http:
    type: boolean
    default: false
    description: |
      The service binds to localhost:4001 with http if true. This exposes an insecure
      endpoint for the service and is not recommended in production environments.

    description: |
      Applies to etcd 3.x+ only.
      A comma-separated list of cipher suites to use for communication between
