Rundeck Telegram Plugin

Sends Rundeck notifications to Telegram a mobile and desktop messaging system.

Installation

1. Download from GitHub (rundeck-telegram-plugin-<version>.jar) or build from source
2. Copy the plugin jar (rundeck-telegram-plugin-<version>.jar) to <Rundeck>/libext directory. It will be picked up and installed instantly - a restart is not required.

Building

The plugin is written in scala so you need to have mill installed (minimum version 0.5.1). Build the plugin:

mill plugin.assembly

The plugin will be placed in out/plugin/assembly/dest/out.jar

it should be renamed rundeck-telegram-plugin-<version>.jar and placed in the libext directory of your rundeck instance.

Configuration

Telegram configuration

You need to set up a Telegram Bot to send the message from. Have a chat with the Botfather to do this. Next you need to get the IDs of the chats that you want to send messages to. The only way to find these is to have them send a message to you bot and pick them out of the JSON. You can do this via

curl "https://api.telegram.org/bot<not-auth-token>/getUpdates"

You can them map your bots and chats to aliases to use in the plugin. Eg put the following in /etc/rundeck/telegram.properties

telegram.ids.bot.messenger_bot=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
telegram.ids.chat.devops-alerts=-123456789
telegram.ids.chat.news=-987654321
telegram.ids.chat.alice=11111111
telegram.ids.chat.bob=22222222

You can then refer to your bots and chats by name in the plugin although the IDs are accepted as well.

Plugin configuration

Got to Configure -> List Plugins -> Notification Plugins -> Telegram to see a list of the configuration options.

You will need to generate a Rundeck API key if you want to include the job log in the message as the plugin retrieves the log via the Rundeck API.

Settings can be edited in the GUI from Configure -> Project Configuration: <Project> -> Edit Configuration File

project.plugin.Notification.TelegramNotification.projectBotAuthToken=messenger_bot
project.plugin.Notification.TelegramNotification.rundeckApiKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Message Templates

The plugin uses Freemarker to render templates. Freemarker is quite an extensive templating language and should be suitable for most needs. Basic substitutions can be done using the ${var} syntax for example:

${job.project}: ${job.group}/${job.name}

could be used to output the project, group and job name.

Templates can come from three sources with the first having priority

1. The message template string in the job definition
2. The message template name in the job definition
3. The message template name in the project or framework property

The location from which the templates are loaded can be controlled with the project.plugin.Notification.TelegramNotification.templateDir configuration setting

For example you might make a template file status.ftl:

${job.project}: ${job.group}/${job.name}
Status: ${status} (${context.job.execid})

For reference the available variables for substitution look like the following:

Emoji Support

Support for emojis can be enabled by setting the Enable emoji parsing flag in Telegram section of the job definition. When this flag is ticked the message will be parsed for strings like :thumbsup: which will then be converted to 👍. See emoji-java for details.

Troubleshooting

If messages are not being send take a look in /var/log/rundeck/service.log for any hints
