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:
Use this as a Markdown reference if you need help with the formatting of this
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.
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.
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.
Though this will be listed in the charm store itself don't assume a user will
know that, so include that information here:
Upstream Project Name
- Upstream website
- Upstream bug tracker
- Upstream mailing list or contact information
- Feel free to add things if it's useful for users
- (string) Map various aliases to existing mailing lists. e.g. email@example.com firstname.lastname@example.org
- (boolean) Enable Spamassassin mail filter
- (boolean) Enable Postfix SPF extensions
- (string) Space separated list of extra deb packages to install.
- (string) Use specified hostname/mailname.
- (string) List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.
- (string) List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.
- (string) Used by the nrpe subordinate charms. 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-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.
- (string) A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup
- (string) The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".
- (string) E-mail used by mailman for e-mail verifications etc.
- (string) Custom Spamassassin policies
- (string) Custom SPF configuration
- debugLevel = 1 defaultSeedOnly = 1 HELO_reject = SPF_Not_Pass Mail_From_reject = Fail PermError_reject = False TempError_Defer = False skip_addresses = 127.0.0.0/8,::ffff:127.0.0.0/104,::1/128
- (string) Override SSL/TLS certificate, defaults to empty which uses the snakeoil
- (string) Override SSL/TLS key, defaults to empty which uses the snakeoil
- (string) Policy map to enforce TLS/SSL
