By default, Travis CI uses email to send build notification, it also support other method, e.g. Slack. This article documents how to set up Slack notification for GitHub project integrated Travis CI.
This article is one of my personal static blog build series:
- Using Hugo and Travis CI To Deploy Blog To Github Pages Automatically
- Using Cloudflare Free SSL In GitHub Pages With Custom Domain
- Setting Up Slack Build Notification in Travis CI for Github Project
I take my personal blog AxdLog as operation example.
Official Document
Travis CI official documents
Slack
This step doesn’t include Slack account registration. Clicking link https://slack.com/signin to login in.
Inputing user name, password
Create New Channel
Clicking Channel or + on the left of the page to create a new channel
Here I set name as github_axdlog and choose private
newly created channel
Token Generation
Clicking link https://my.slack.com/services/new/travis into Travis configuration page, choose target channel (github_axdlog) in the selection menu
Newly generated token is maxdsre:ne18Xpc5RbzM1hIdd34nN2aE
Encrypting your credentials
Your integration token is semi-secret, but we recommend encrypting your credentials using the Travis command line client.
Encrypting Credentials
After I failed to install travis according to official docs, I choose Docker image to generate encrypted credential.
If you don’t know how to install Docker, you may consider reference my blog Installing And Configuring Docker Community Edition(CE) On GNU/Linux.
