juju charm for bundleservice service
The bundleservice is a stand-alone service and has no other charm dependencies.
All examples here are for juju 2 command-line usage but the charm can be deployed with juju 1.
Upgrading is done by triggering the config-changed hook by setting the source
configuration value. It can either be set to a new value or by an innocuous
change, such as adding a trailing space. The equivalent of apt-get update and
apt-get upgrade will be done . Afterwards, bundleservice will be
restarted.
Change the source config to trigger apt-get update & install bundleservice package. Adding whitespace to source is a good option:
juju get-config bundleservice # note the source
juju set-config bundleservice source='<SAME AS OLD SOURCE WITH A TRAILING WHITESPACE>'
The bundleservice can be scaled out by deploying more units and using a load balancer. To use apache as a load balancer, deploy bundleservice and apache.
juju deploy apache2
juju deploy . bundleservice
Add relations between them
juju add-relation bundleservice apache2:balancer
Create a vhost template that uses the balancer, write the something like the following to a file (e.g. /tmp/vhost-jem.tmpl)
<VirtualHost _default_:80>
ProxyPreserveHost On
ProxyPass / balancer://bundleservice/
ProxyPassReverse / balancer://bundleservice/
</VirtualHost>
Upload the configuration to the apache charm
juju set-config apache2 "vhost_http_template=$(base64 /tmp/vhost-bundleservice.tmpl)"
Expose apache
juju expose apache2
Additional bundleservice capacity can now be added by adding more units
juju add-unit bundleservice
The source for getting the bundleservice can be set. It can be a public PPA or a sources.list entry if using a private PPA, e.g.
juju set-config bundleservice source='deb https://USER:TOKEN@private-ppa.launchpad.net/yellow/theblues-unstable/ubuntu trusty main'
The TCP port on which to listen can be set using the listen-port variable.
juju set-config bundleservice listen-port=8000
The bundleservice charm only supports being deployed on trusty (Ubuntu 14.04) and later. This can cause problems with subordinate charms, at the time of writing there is no trusty/nrpe charm. If nrpe functionality is required ~rcj/trusty/nrpe is known to work.
