hello-aliyun-devops

Hello Alibaba Cloud DevOps! Just a quick CI/CD test with Alibaba Cloud

Usage

1. Fork this repository

2. Create a personal instance of Alibaba Cloud Container Registry (ACR) and a namespace if not already

3. Create a repository and select your GitHub fork as the code source

4. In the build options for the repository, add a build rule that triggers a build for every commit to the main branch, and tag the resulting image as latest (or otherwise)

5. Click "Build" under "Actions" to manually trigger the build the first time, ensuring that an image will be available

6. Create an ACK cluster. For simplicity, you might want to create a serverless cluster, i.e. ASK

7. Configure kubectl locally (or otherwise) to connect to your cluster

8. Use kubectl to quickly spin up and expose a deployment using the image IMG_NAME you just built:

   kubectl create deploy hello-devops --image=$IMG_NAME --replicas=2 --port=80
   kubectl expose deploy hello-devops --type=LoadBalancer

9. Fetch the load balancer IP using kubectl get svc or via the ACK web console (or otherwise) and visit that public IP to verify that the deployment is working. You should see text similar to what is shown below, modulo font size:

   Hello Alibaba Cloud DevOps!
   Version: 4
   

10. In the ACK web console with your cluster selected and under "Workloads > Deployments", choose your hello-devops deployment, click on the "Triggers" tab and create a "Redeploy" trigger

11. Copy the generated trigger URL to your repository under section "Trigger" - create a new trigger, paste the URL and name the trigger accordingly

12. Make code changes to your GitHub fork - for example, you might want to bump the version number in index.html - and commit your changes. If performing these actions via git, remember to push your changes as well

13. Watch and observe as an automated build is triggered under your ACR repository, a new image is created, and the trigger is activated which re-deploys the app on your ACK cluster. Wait a while, then re-visit the public load balancer IP associated with your hello-devops deployment and you shoud see the changes appear

Congratulations - you've created an automated CI/CD pipeline with Alibaba Cloud!

Remarks

Since the image used in this demo is based on Alibaba Cloud Linux 3 which depends on package mirrors and repositories only available within Alibaba Cloud, the image might not build and deploy correctly outside Alibaba Cloud, e.g. on other cloud platforms or locally
