Llama Charmers Next Canonical Livepatch

Overview

This subordinate charm provides live kernel updates to its unit via the Canonical Livepatch Service.

The canonical-livepatch software is automatically installed from the Snap Store.

You will need to supply your key from https://ubuntu.com/livepatch via juju set (1.x) or juju config (2.x)

Nagios checks are automatically deployed if you add an appropriate nrpe-external-master relation.

Usage

This is a subordinate charm, so must be related to your primary service(s):

juju deploy canonical-livepatch

juju add-relation <your_primary_charm_name> canonical-livepatch

You will need to supply your key from https://ubuntu.com/livepatch via juju set (Juju 1.x):

juju set canonical-livepatch livepatch_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Or via juju config (Juju 2.x)

juju config canonical-livepatch livepatch_key=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Configuration

The livepatch_key setting must be configured in order for the software to function correctly - see above.

By default, the livepatch software will attempt to retrieve its patch data directly over the network. If you'd like to use a proxy for this traffic instead, you can set the livepatch_proxy value to the address of your proxy server.

Likewise, if you need to use a proxy server to access the Snap Store, snap_proxy can also be set to the address of your proxy server.

Alternatively, if you've configured a proxy for all applications in your environment via juju model-config, the charm will detect this and automatically do the right thing. It'll use http-proxy or https-proxy if either are set, with the latter being preferred.

If two different proxies are set via model config and charm config, the latter will be preferred.

Testing

To run tests use: make test

Note: functional tests are not available on trusty.
