Argo Workflows workflow helloworld

July 6, 2021

这里使用官方文档中的 docker/whalesay 来创建一个 helloworld 的 workflow

docker run docker/whalesay cowsay "hello world"

网络问题我手动下载镜像 (这里已经通过tag重命名了）

microk8s ctr image pull docker.io/docker/whalesay:latest
microk8s ctr image pull docker.io/libaibai/whalesay:latest

microk8s ctr image pull docker.io/argoproj/argoexec:v3.0.3

apiVersion: argoproj.io/v1alpha1
kind: Workflow                  # new type of k8s spec
metadata:
  generateName: hello-world-    # name of the workflow spec
  namespace: argo
spec:
  entrypoint: whalesay          # invoke the whalesay template
  templates:
  - name: whalesay              # name of the template
    container:
      image: docker/whalesay
      command: [cowsay]
      args: ["hello world"]
      resources:                # limit the resources
        limits:
          memory: 32Mi
          cpu: 100m

出现了错误

Unable to attach or mount volumes: unmounted volumes=[docker-sock], unattached volumes=[kube-api-access-btrhw podmetadata docker-sock my-minio-cred]: timed out waiting for the condition

参考

https://argoproj.github.io/argo-workflows/workflow-controller-configmap.yaml

这里使用的是 microk8s ，没有docker.sock，只有 containerd.sock

/var/snap/microk8s/common/run/containerd.sock

这里我直接去按了一个docker
