Simple utility you can use as a custom Tekton triggers webhook interceptor when receiving Slack interactive message payloads in response to user interaction (i.e. clicking on buttons etc) to trigger things in your Tekton CICD system. It can also be used respond to Slack slash commands.
For Slack interactive message posts, for convience it lightly mutates the original JSON and adds an action_values property which is just an array of the selected values under actions. Completely ignorable if you don't want to use it.
There are no additional mutations for Slack slash command posts.
Usage of ./slack-payload-handler:
-debug-request
Optional, print requests to STDOUT, default false
-debug-response
Optional, print responses to STDOUT, default false
-listen-port int
Optional, port to listen on, default 8080 (default 8080)
docker run -p 8080:8080 -it bitsofinfo/slack-payload-handler \
slack-payload-handler --debug-request true --debug-response true --listen-port 8080
Simulate a interactive message post:
$> ./slack-payload-handler --debug-request true --debug-response true
$> curl -k -X POST localhost:8080 --data-urlencode 'payload={"x":"b","actions":[{"value":"1"}]}'
{"action_values":["1"],"actions":[{"value":"1"}],"x":"b"}
Simulate a slash command message post:
$> ./slack-payload-handler --debug-request true --debug-response true
$> curl --location --request POST 'http://localhost:8080/' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'token=123' \
--data-urlencode 'command=mycommand' \
--data-urlencode 'dog=cat'
{"command":"mycommand","dog":"cat","token":"123"}
$> ./slack-payload-handler --debug-request true --debug-response true
$> curl -k -X POST localhost:8080 --data-urlencode "payload=$(cat slack.test.json)"
