Container Service for Kubernetes:Create an Argo workflow

Step 1: Install the Argo CLI

The Alibaba Cloud Argo CLI is fully compatible with the open-source version and adds metrics and logging capabilities, including CPU and memory consumption, execution cost, and logs from deleted Pods.

1. Download the Alibaba Cloud Argo CLI.

   These steps are for Linux. For macOS, download the Argo CLI from https://ack-one.oss-cn-hangzhou.aliyuncs.com/cli/v3.4.12/argo-cli-aliyun-darwin.

   wget https://ack-one.oss-cn-hangzhou.aliyuncs.com/cli/v3.4.12/argo-cli-aliyun-linux

2. Make argo-cli-aliyun-linux executable.

   chmod +x argo-cli-aliyun-linux

3. Move the executable to a directory in your PATH, such as /usr/local/bin/.

   mv argo-cli-aliyun-linux /usr/local/bin/argo

Step 2: Create a workflow

1. Create a file named helloworld-workflow.yaml with the following content.

   apiVersion: argoproj.io/v1alpha1
   kind: Workflow
   metadata:
     generateName: helloworld-- # Workflow name prefix
   spec:
     entrypoint: helloworld # Specifies the entrypoint workflow template
     templates:
     - name: helloworld
       container:
         image: mirrors-ssl.aliyuncs.com/busybox:latest
         command:
         - sh
         - -c
         args:
         - echo "Hello, world!";
           sleep 60;

2. Submit the workflow.

   argo submit helloworld-workflow.yaml

3. Check the workflow status.

   1. List workflows.

      argo list

      Expected output:

      NAME               STATUS      AGE   DURATION   PRIORITY
      helloworld-lgdpp   Succeeded   2m    37s        0

   2. Get workflow details.

      argo get helloworld-lgdpp

      Expected output:

      Name:                hello-world-lgdpp
      Namespace:           default
      ServiceAccount:      unset (will run with the default ServiceAccount)
      Status:              Succeeded
      Conditions:
       PodRunning          False
       Completed           True
      ....
      Duration:            1 minute 46 seconds
      Progress:            1/1
      ResourcesDuration:   17s*(1 cpu),17s*(100Mi memory)
      STEP                  TEMPLATE  PODNAME            DURATION  MESSAGE
       ✔ hello-world-lgdpp  helloworld  hello-world-lgdpp  1m
