# Overview
|
||||
|
||||
Describe the intended usage of this charm and anything unique about how this
|
||||
charm relates to others here.
|
||||
|
||||
This README will be displayed in the Charm Store, it should be either Markdown
|
||||
or RST. Ideal READMEs include instructions on how to use the charm, expected
|
||||
usage, and charm features that your audience might be interested in. For an
|
||||
example of a well written README check out Hadoop:
|
||||
http://jujucharms.com/charms/precise/hadoop
|
||||
|
||||
Use this as a Markdown reference if you need help with the formatting of this
|
||||
README: http://askubuntu.com/editing-help
|
||||
|
||||
This charm provides [service][]. Add a description here of what the service
|
||||
itself actually does.
|
||||
|
||||
Also remember to check the [icon guidelines][] so that your charm looks good
|
||||
in the Juju GUI.
|
||||
|
||||
# Usage
|
||||
|
||||
Step by step instructions on using the charm:
|
||||
|
||||
juju deploy servicename
|
||||
|
||||
and so on. If you're providing a web service or something that the end user
|
||||
needs to go to, tell them here, especially if you're deploying a service that
|
||||
might listen to a non-default port.
|
||||
|
||||
You can then browse to http://ip-address to configure the service.
|
||||
|
||||
## Scale out Usage
|
||||
|
||||
If the charm has any recommendations for running at scale, outline them in
|
||||
examples here. For example if you have a memcached relation that improves
|
||||
performance, mention it here.
|
||||
|
||||
## Known Limitations and Issues
|
||||
|
||||
This not only helps users but gives people a place to start if they want to help
|
||||
you add features to your charm.
|
||||
|
||||
# Configuration
|
||||
|
||||
The configuration options will be listed on the charm store, however If you're
|
||||
making assumptions or opinionated decisions in the charm (like setting a default
|
||||
administrator password), you should detail that here so the user knows how to
|
||||
change it immediately, etc.
|
||||
|
||||
# Contact Information
|
||||
|
||||
Though this will be listed in the charm store itself don't assume a user will
|
||||
know that, so include that information here:

# CephFS Charm
|
||||
|
||||
# Overview
|
||||
|
||||
Ceph is a distributed storage and network file system designed to provide
|
||||
excellent performance, reliability, and scalability.
|
||||
|
||||
This charm deploys a Ceph MDS cluster.
|
||||
juju
|
||||
|
||||
Usage
|
||||
=====
|
||||
|
||||
Boot things up by using::
|
||||
|
||||
juju deploy -n 3 --config ceph.yaml ceph-mon
|
||||
juju deploy -n 3 --config ceph.yaml ceph-osd
|
||||
|
||||
You can then deploy this charm by simply doing::
|
||||
|
||||
juju deploy -n 3 --config ceph.yaml ceph-fs
|
||||
juju add-relation ceph-fs ceph-mon
|
||||
|
||||
Once the ceph-mon and osd charms have bootstrapped the cluster, it will notify the ceph-fs charm.
