debug:
type: boolean
default: False
description: Enable debug logging
prefer-ipv6:
type: boolean
default: False
description: |
If True enables IPv6 support. The charm will expect network interfaces
to be configured with an IPv6 address. If set to False (default) IPv4
is expected.
.
NOTE: these charms do not currently support IPv6 privacy extension. In
order for this charm to function correctly, the privacy extension must be
disabled and a non-temporary address must be configured/available on
your network interface.
corosync_mcastaddr:
type: string
default: 226.94.1.1
description: |
Multicast IP address to use for exchanging messages over the network.
If multiple clusters are on the same bindnetaddr network, this value
can be changed.
corosync_bindiface:
type: string
default:
description: |
Default network interface on which HA cluster will bind to communication
with the other members of the HA Cluster.
corosync_mcastport:
type: int
default:
description: |
Default multicast port number that will be used to communicate between
HA Cluster nodes.
corosync_key:
type: string
default: "64RxJNcCkwo8EJYBsaacitUvbQp5AW4YolJi5/2urYZYp2jfLxY+3IUCOaAUJHPle4Yqfy+WBXO0I/6ASSAjj9jaiHVNaxmVhhjcmyBqy2vtPf+m+0VxVjUXlkTyYsODwobeDdO3SIkbIABGfjLTu29yqPTsfbvSYr6skRb9ne0="
description: |
This value will become the Corosync authentication key. To generate
a suitable value use:
.
sudo corosync-keygen
sudo cat /etc/corosync/authkey | base64 -w 0
.
This configuration element is mandatory and the service will fail on
install if it is not provided. The value must be base64 encoded.
stonith_enabled:
type: string
default: 'False'
description: |
Enable resource fencing (aka STONITH) for every node in the cluster.
This requires MAAS credentials be provided and each node's power
parameters are properly configured in its invenvory.
maas_url:
type: string
default:
description: MAAS API endpoint (required for STONITH).
maas_credentials:
type: string
default:
description: MAAS credentials (required for STONITH).
cluster_count:
type: int
default: 2
description: |
Number of peer units required to bootstrap cluster services.
.
If less that 3 is specified, the cluster will be configured to
ignore any quorum problems; with 3 or more units, quorum will be
enforced and services will be stopped in the event of a loss
of quorum.
monitor_host:
type: string
default:
description: |
One or more IPs, separated by space, that will be used as a saftey check
for avoiding split brain situations. Nodes in the cluster will ping these
IPs periodicaly. Node that can not ping monitor_host will not run shared
resources (VIP, shared disk...).
monitor_interval:
type: string
default: 5s
description: |
Time period between checks of resource health. It consists of a number
and a time factor, e.g. 5s = 5 seconds. 2m = 2 minutes.
netmtu:
type: int
default:
description: |
Specifies the corosync.conf network mtu. If unset, the default
corosync.conf value is used (currently 1500). See 'man corosync.conf' for
detailed information on this config option.
corosync_transport:
type: string
default: "multicast"
description: |
Two supported modes are multicast (udp) or unicast (udpu)
nagios_context:
default: "juju"
type: string
description: |
Used by the nrpe-external-master subordinate charm.
A string that will be prepended to instance name to set the host name
in nagios. So for instance the hostname would be something like:
.
juju-postgresql-0
.
If you're running multiple environments with the same services in them
this allows you to differentiate between them.
nagios_servicegroups:
default: ""
type: string
description: |
A comma-separated list of nagios servicegroups.
If left empty, the nagios_context will be used as the servicegroup
