一、上传到私有仓储

docker pull busybox:1.33.1
docker tag busybox:1.33.1 192.168.31.185/public/busybox:1.33.1
docker push 192.168.31.185/public/busybox:1.33.1

      initContainers:
        - command:
            - sh
            - '-c'
            - echo 2000 > /proc/sys/net/core/somaxconn
          image: 'harbor.net.com/public/busybox:1.33.1'
          imagePullPolicy: Always
          name: busyboxhost
          resources: {}
          securityContext:
            privileged: true
          terminationMessagePath: /temp/termination-log
