This proposal has been superseded by a proposal from 2015-11-24.
Commit message
Description of the change
This branch changes the pause action to change the kv database instead of calling set_os_
This prevents the charm from immediately bouncing back to active after a 'pause' action was performed.
A follow up branch will add a bit more logic to deal with hacluster so it stops sending requests for the unit.

[ionutbalutoiu, r=thedac] Adds additional variables to the image-service relation. These are available only when a relation with Swift object storage is present.
In case any charm needs to generate temporary URLs from Glance with Swift backend, it needs a temp-url-key which must be posted to Swift with the glance account. (Details: http://docs.openstack. org/liberty/ config- reference/ content/ object- storage- tempurl. html)
This is needed for OpenStack Ironic charm (http://bazaar. launchpad. net/~cloudbasei t/charms/ trusty/ ironic/ trunk/view/ head:/hooks/ ironic_ context. py#L76), but might also be generally useful. - 151. By Corey Bryant

593 | +# |
594 | +# 1. Update metadata.yaml |
595 | +# |
596 | +# provides: |
597 | +# (...) |
598 | +# nrpe-external-master: |
599 | +# interface: nrpe-external-master |

607 | +# interface: local-monitors |
608 | +# scope: container |
609 | + |
610 | +# |
611 | +# 2. Add the following to config.yaml |
612 | +# |
613 | +# nagios_context: |
614 | +# default: "juju" |
615 | +# type: string |
616 | +# description: | |
617 | +# Used by the nrpe subordinate charms. |
618 | +# A string that will be prepended to instance name to set the host name |
619 | +# in nagios. So for instance the hostname would be something like: |
620 | +# juju-myservice-0 |
621 | +# If you're running multiple environments with the same services in them |
622 | +# this allows you to differentiate between them. |

628 | +# If left empty, the nagios_context will be used as the servicegroup |
629 | +# |
630 | +# 3. Add custom checks (Nagios plugins) to files/nrpe-external-master |
631 | +# |
632 | +# 4. Update your hooks.py with something like this: |

634 | +# from charmsupport.nrpe import NRPE |

3147 | + This parsing method supports a few different formats for the config |
3148 | + flag values to be parsed: |
3149 | + |
3150 | + 1. A string in the simple format of key=value pairs, with the possibility |
3151 | + of specifying multiple key value pairs within the same string. For |
3152 | + example, a string in the format of 'key1=value1, key2=value2' will |

3161 | + |
3162 | + {'key1', 'value1', |
3163 | + 'key2', 'value2,value3,value4'} |
3164 | + |
3165 | + 3. A string containing a colon character (:) prior to an equal |
3166 | + character (=) will be treated as yaml and parsed as such. This can be |
3167 | + used to specify more complex key value pairs. For example, |
3168 | + a string in the format of 'key1: subkey1=value1, subkey2=value2' will |
3169 | + return a dict of: |
3170 | + |
