Description of the change
small charm to implement pxe/netboot server. It seems to work much better with wily, I had a lot of issues getting it working with trusty. This should hopefully give a shorter path to xenial too though, which we should definitely be looking to transition to.

557 | +"""Charm Helpers ansible - declare the state of your machines. |
558 | + |
559 | +This helper enables you to declare your machine state, rather than |
560 | +program it procedurally (and have to test each change to your procedures). |
561 | +Your install hook can be as simple as:: |
562 | + |
563 | + {{{ |
564 | + import charmhelpers.contrib.ansible |
565 | + |
566 | + |
567 | + def install(): |
568 | + charmhelpers.contrib.ansible.install_ansible_support() |
569 | + charmhelpers.contrib.ansible.apply_playbook('playbooks/install.yaml') |
570 | + }}} |
571 | + |
572 | +and won't need to change (nor will its tests) when you change the machine |
573 | +state. |
574 | + |
575 | +All of your juju config and relation-data are available as template |
576 | +variables within your playbooks and templates. An install playbook looks |
577 | +something like:: |
578 | + |
579 | + {{{ |

1010 | +# |
1011 | +# 1. Update metadata.yaml |
1012 | +# |
1013 | +# provides: |
1014 | +# (...) |
1015 | +# nrpe-external-master: |
1016 | +# interface: nrpe-external-master |

1024 | +# interface: local-monitors |
1025 | +# scope: container |
1026 | + |
1027 | +# |

1030 | +# nagios_context: |
1031 | +# default: "juju" |
1032 | +# type: string |

1035 | +# A string that will be prepended to instance name to set the host name |
1036 | +# in nagios. So for instance the hostname would be something like: |
1037 | +# juju-myservice-0 |
1038 | +# If you're running multiple environments with the same services in them |
1039 | +# this allows you to differentiate between them. |

1045 | +# If left empty, the nagios_context will be used as the servicegroup |
1046 | +# |
1047 | +# 3. Add custom checks (Nagios plugins) to files/nrpe-external-master |
1048 | +# |

1312 | +''' |
1313 | +Functions for managing volumes in juju units. One volume is supported per unit. |
1314 | +Subordinates may have their own storage, provided it is on its own partition. |
1315 | + |
1316 | +Configuration stanzas:: |
1317 | + |
1318 | + volume-ephemeral: |
1319 | + type: boolean |
1320 | + default: true |
1321 | + description: > |
1322 | + If false, a volume is mounted as sepecified in "volume-map" |
1323 | + If true, ephemeral storage will be used, meaning that log data |
1324 | + will only exist as long as the machine. YOU HAVE BEEN WARNED. |
1325 | + volume-map: |
1326 | + type: string |
1327 | + default: {} |
1328 | + description: > |
1329 | + YAML map of units to device names, e.g: |
1330 | + "{ rsyslog/0: /dev/vdb, rsyslog/1: /dev/vdb }" |
1331 | + Service units will raise a configure-error if volume-ephemeral |
1332 | + is 'true' and no volume-map value is set. Use 'juju set' to set a |
1333 | + value and 'juju resolved' to complete configuration. |
