SSL Certificate Expiry Checker

Check SSL certificate expiry time for your domains.

Inputs

domain

Required: The site domain to be checked (without protocol).

Outputs

ssl-expire-date

The expiration date of the SSL certificate.

ssl-expire-days-left

The number of days left until the SSL certificate expires.

Example Usage

- name: Check domain SSL expire date
  id: check-ssl-expiry
  uses: surmon-china/action-ssl-cert-expiry-checker@v1.0.0
  with:
    domain: surmon.me

- run: echo 'SSL cert has ${{ steps.check-ssl-expiry.outputs.ssl-expire-days-left }} days left'
  if: ${{ steps.check-ssl.outputs.ssl-expire-days-left }}

Advanced Example

You can create a workflow based on this action to check your domains. This workflow will be scheduled by cron to run every day around 8:00 UTC (it might be slightly delayed due to GitHub’s scheduling).

If the SSL certificate’s lifespan (number of days) is below a specified limit (e.g., 10 days), it will create a new issue.

name: Check domains

on:
  schedule:
    - cron: "0 8 * * *"

jobs:
  check-ssl-expiry:
    runs-on: ubuntu-latest
    name: Check domain SSL certificates expire time
    strategy:
      matrix:
        domain:
          - github.com
          - surmon.me

    steps:
      - name: Check domain SSL certificates expire time
        id: check-ssl-expiry
        uses: surmon-china/action-ssl-cert-expiry-checker@v1.0.0
        with:
          domain: ${{ matrix.domain }}

      - name: Create an issue if SSL lifespan days number is below limit
        if: ${{ steps.check-ssl-expiry.outputs.ssl-expire-days-left < 10 }}
        uses: rishabhgupta/git-action-issue@v2
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          title: ${{ matrix.domain }} — SSL cert expires in ${{ steps.check-ssl-expiry.outputs.ssl-expire-days-left }} days
          body: ${{ steps.check-ssl-expiry.outputs.ssl-expire-date }}
