[DOCKER] Notify the build result with slack with CircleCI. You can do it in 5 minutes.

Notify slack of CircleCI job results

This article is about some kind of automated testing and how to notify slack of the results of automated deployment. We've put it together in a way that's easy, easy to understand, and quick, so let's get it done and do something different! !!

environment

CircleCI 2.1
orbs: slack: circleci/[email protected]

conditions

1. You have already created some kind of job.
2. You can build normally.
3. I'm using slack

If you meet these conditions, follow the procedure for the first time. If this is not the case, be aware that it can cause confusion when an error occurs!

Process

1. Get webhook
2. Set environment variables on CircleCI
3. Describe the required sources in the config.yml file

1. Get a webhook

https://slack.com/services/new/incoming-webhook

⬆️⬆️ Please get the URL to set in the environment variable from the above URL. After logging in to the specified account and specifying the channel to notify, the URL will be issued.

When you log in, the screen for selecting a channel will appear in the above picture, so select it. The URL will appear on the next screen, so copy it and make a note of it.

2. Set environment variables in CircleCI

Set environment variables in CircleCI. Register environment variables on the project setting screen Select a project and import

name is SLACK_WEBHOOK Value copy and paste the URL you wrote down earlier

3. Set notification parameters in the /.circleci/config.yml file

config.yml

orbs:
  slack: circleci/[email protected]
    

#abridgement

    - slack/status:
        success_message: ':circleci-pass: $CIRCLE_BRANCH build is complete\n:github_octocat: User：$CIRCLE_USERNAME'
        failure_message: ':circleci-fail: $CIRCLE_BRANCH build failed\n:github_octocat: User：$CIRCLE_USERNAME'
        webhook: '${SLACK_WEBHOOK}'

Make these two types of description

If you run a job with this and get a notification, it is successful.

When you receive this notification, you are done. Thank you for your hard work! !!
