README.md

This sample sub-directory contains an EventListener and Pipeline definition that you can include in your Tekton pipeline configuration to run an example of the slack-post-message task.

1. Create or update a Toolchain so it includes:

   • a Slack integration
   • the repository containing this tekton task
   • a Tekton pipeline definition

   

2. Add the definitions of this task and the sample (slack and slack/sample paths)

   

3. Add the environment properties as needed:

   • domain (optional) the Slack domain to send the message to.
   • channel (optional) the channel to post to (overrides the dafault channel as set in the Slack webhook).
   • message-format (optional) the format of the message (text or JSON).
   • message-script (optional) Shell script that provides messsage content.
   • message (optional) the message to post to Slack.

Note: when using JSON format, the message is posted as-is to Slack.

4. Create a manual trigger to start the sample listener

   

5. Run the pipeline

6. The message is posted to Slack

   

7. Optional: check the execution log

   

8. Optional: Create a message using snippet

   a) Define the snippet in the message-script environment property of the pipeline

   message-script: `echo 'Message sent from PipelineRun' ${PIPELINE_RUN_NAME}; echo 'uid:' ${PIPELINE_RUN_ID}; echo 'buildNumber:' ${BUILD_NUMBER};`
   

   Note: this could also be done in the trigger-template or pipeline definition

   

   b) After running the pipeline, a new message like the following should have been posted to the Slack channel

   

   c) Check the execution log
