      env:
        SLACK_WEBHOOK: ${{ secrets.SLACK_WEBHOOK }}

SLACK_COLOR	good (green)	You can pass an RGB value like #efefef which would change color on left side vertical line of Slack message.
SLACK_MESSAGE	Generated from git commit message.	The main Slack message in attachment. It is advised not to override this.
SLACK_TITLE	Message	Title to use before main Slack message

This GitHub action supports Hashicorp Vault.

To enable Hashicorp Vault support, please define following GitHub secrets:

You will need to change secrets line in slack-notify.yml file to look like below.

on: push
name: Slack Notification Demo
jobs:
  slackNotification:
    name: Slack Notification
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Slack Notification
      uses: rtCamp/[email protected]
      env:
        VAULT_ADDR: ${{ secrets.VAULT_ADDR }}
        VAULT_TOKEN: ${{ secrets.VAULT_TOKEN }}

GitHub action uses VAULT_TOKEN to connect to VAULT_ADDR to retrieve slack webhook from Vault.

In the Vault, the Slack webhook should be setup as field webhook on path secret/slack.
