Post Jenkins console output to Slack
Premise
Build result notification etc. can already be posted to Slack (plugin is set)
- If you google with "Jenkins Slack notification" etc., there are many ways to hit, so please refer to it.
Get Jenkins build number
import os
build_number = os.environ.get('BUILD_NUMBER')
BUILD_NUMBER on the Jenkins side Environment variables are prepared, so use this https://wiki.jenkins.io/display/JA/Building+a+software+project
Why get the build number?
There is a "build history" on the Jenkins management screen,
If you manually define the directory that specifies the console output result, such as "13" or "14"
Every time I build, the build number is updated, so I get an error saying there is no such directory . So to avoid that, get a new build number each time. To do
Install Slacker library
pip install slacker
Use SlackAPI to decide which channel to post
post_log.py
from slacker import Slacker
import sys
import os
token = 'Your SLACK token'
channel = 'Please enter the channel name'
build_number = os.environ.get('BUILD_NUMBER')
file = f'~/builds/{build_number}/log'
slacker = Slacker(token)
slacker.files.upload(file_=file, channels=channel)
files.upload official documentation https://api.slack.com/methods/files.upload
Add an execution shell on the Jenkins administration screen
Operation check
It is also possible to add comments, so please add parameters there.
Once you've confirmed that it's actually posted to Slack, it's OK!
