Docker hello-world不起作用

Question

操作系統：Mac OS X.

我安裝了boot2docker並啟動它，顯示了一些錯誤：

wangyaos-MBP-2:~ wangyao$ boot2docker start

Waiting for VM and Docker daemon to start...
..........................o
Started.

Writing /Users/wangyao/.boot2docker/certs/boot2docker-vm/ca.pem
Writing /Users/wangyao/.boot2docker/certs/boot2docker-vm/cert.pem
Writing /Users/wangyao/.boot2docker/certs/boot2docker-vm/key.pem

To connect the Docker client to the Docker daemon, please set:
    export DOCKER_TLS_VERIFY=1
    export DOCKER_HOST=tcp://192.168.59.103:2376
    export DOCKER_CERT_PATH=/Users/wangyao/.boot2docker/certs/boot2docker-vm

    export DOCKER_CERT_PATH=/Users/wangyao/.boot2docker/certs/boot2docker-vm
    export DOCKER_TLS_VERIFY=1


wangyaos-MBP-2:~ wangyao$ docker run hello-world

Post http:///var/run/docker.sock/v1.19/containers/create: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?

我需要做些什么來讓$ docker run hello-world工作？

Answer 1

您需要在當前shell中執行以下boot2docker shellinit ，而不是運行boot2docker shellinit ：

eval "$(boot2docker shellinit)"

boot2docker shellinit命令將所需的export語句打印到標准輸出。 這些語句設置了連接到boot2docker虛擬機所需的環境變量。

通過使用eval $()包裝boot2docker shellinit的輸出，變量將導出到當前shell而不是僅打印。 這應該允許您連接到boot2docker vm，這是運行示例所必需的。
