无法验证'docker'驱动程序（kubernetes）

Question

每次我尝试在Linux（ubuntu 18.04）上进行minikube启动时，总​​是会收到此Docker验证错误。

Answer 1

这对我来说很好：

myuser@mymachine:~$ minikube start --driver=docker
?  minikube v1.11.0 on Ubuntu 16.04
✨  Using the docker driver based on user configuration
?  Starting control plane node minikube in cluster minikube
?  Pulling base image ...
?  Creating docker container (CPUs=2, Memory=2200MB) ...
?  Found network options:
    ▪ NO_PROXY=169.254.169.254
?  Preparing Kubernetes v1.18.3 on Docker 19.03.2 ...
    ▪ env NO_PROXY=169.254.169.254
    ▪ kubeadm.pod-network-cidr=10.244.0.0/16
?  Verifying Kubernetes components...
?  Enabled addons: default-storageclass, storage-provisioner
?  Done! kubectl is now configured to use "minikube"

确保/var/run/docker.sock拥有用户访问权限的正确权限

myuser@mymachine:~$ sudo chmod o+rw /var/run/docker.sock
myuser@mymachine:~$ ls -la /var/run/docker.sock
srw-rw-rw- 1 root docker 0 Jul  6 17:42 /var/run/docker.sock

确保docker守护程序正在运行：

myuser@mymachine:~$ ps -Af | grep dockerd
root     12723     1  0 Jul06 ?        00:01:11 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
root     18598 17596  0 19:19 ?        00:00:05 /usr/bin/dockerd -H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock --default-ulimit=nofile=1048576:1048576 --tlsverify --tlscacert /etc/docker/ca.pem --tlscert /etc/docker/server.pem --tlskey /etc/docker/server-key.pem --label provider=docker --insecure-registry 10.96.0.0/12
