Question

在我们的kubernetes集群中部署jenkins pod时，kubernetes返回以下错误：

Error: failed to create containerd task: OCI runtime create failed: container_linux.go:346: starting container process caused "process_linux.go:449: container init caused \"rootfs_linux.go:58: mounting \\\"/var/run/docker.sock\\\" to rootfs \\\"/run/containerd/io.containerd.runtime.v1.linux/k8s.io/jenkins/rootfs\\\" at \\\"/run/containerd/io.containerd.runtime.v1.linux/k8s.io/jenkins/rootfs/run\\\" caused \\\"not a directory\\\"\"": unknown Back-off restarting failed container

我的部署Yaml文件：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: jenkins
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: jenkins
    spec:
      imagePullSecrets:
        - name: my-secret-key
      containers:
        - name: jenkins
          image: image-repo-url
          env:
            - name: JAVA_OPTS
              value: -Djenkins.install.runSetupWizard=false
          ports:
            - name: http-port
              containerPort: 8080
            - name: jnlp-port
              containerPort: 50000
          volumeMounts:
            - name: jenkins-home
              mountPath: /var/jenkins_home
            - name: docker-sock
              mountPath: /var/run/
            - name: docker-storage
              mountPath: /var/lib/docker
          securityContext:
            privileged: true
      volumes:
        - name: jenkins-home
          emptyDir: {}
        - name: docker-sock
          hostPath:
            path: /var/run/docker.sock
        - name: docker-storage
          emptyDir: {}

我尝试了docker-sock卷：

- name: docker-sock
  hostPath:
  path: /var/run/docker.sock
  type: file
--- and ---
- name: docker-sock
  hostPath:
  path: /var/run/docker.sock
  type: Socket

但是它不起作用。实际上，此配置有效。但是ıt目前无法正常工作。

我尝试了卷装载：

volumeMounts:
- name: jenkins-home
  mountPath: /var/jenkins_home
- name: docker-sock
  mountPath: /var/run/docker.sock

部署已创建。但是Docker无法正常工作。

我们正在使用IBM Cloud Kubernetes服务。

较新的IKS集群未安装Docker-它们使用容器式执行容器。

如果您仍然想在Jenkins上执行Docker，则可以将Kubernetes插件和Pod与dind容器一起使用，也可以基于Dind重建自己的jenkins-类似于：https://hub.docker.com/r/vixns/jenkins-dind/

Kubernetes部署失败的jenkins部署“无法创建容器化任务”
