IRCbot and RabbitMQ-server consumer
The IRCbot charm was created by Canonical hyperscale team to listen to messages from a RabbitMQ-server instance and then show this messages in an IRC channel.
IRCbot charm requires RabbitMQ-server charm. Its configuration has two parts, one related with IRCbot and other with RabbitMQ-server.
If you deploy each charm separately:
$ juju deploy ~ce-hyperscale/scalebot-ircbot
$ juju deploy rabbitmq-server
Then you need to add the relation between charms:
juju add-relation rabbitmq-server scalebot-ircbot
The IRCbot charm will create a systemd unit called
ircbot.service to run the IRCbot service. This service is responsible for staying connected to the IRC network and for joining a channel and then reading the messages from RabbitMQ-server and showing these messages formatted in IRC channel.
Where do the messages to RabbitMQ-server come from?
We are using a Jenkins instance with the MQ-notifier plugin. The MQ-notifier plugin sends messages whenever a build is started and finished.
It also sends a message when a build enters and leaves the queue (but these messages are ignored by IRCbot charm - we are just interested in knowing when the job started and when it finished - with
If it fails, you can make your bot ping someone in IRC channel (
irc_nick_to_alert config) and/or you can just add
scalebot-jenkins-failure to be highlighted in your IRC client settings.
We tested this charm in both x86_64 and aarch64 architectures.
- (string) Space separated list of extra deb packages to install.
- (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) IRC authentication method (server OR nickserv)
- (string) IRC bot-nickname
- (string) IRC channel name, do not need to add "#"

- (string) IRC nickname to alert if any
- (string) IRC password if auth_method is server or nickserv
- (int) IRC server port number
