用boot2docker 执行命令时总是报这个错误?有人知道是什么问题吗?

$ docker images
Get http://127.0.0.1:2375/v1.19/images/json: dial tcp 127.0.0.1:2375: ConnectEx tcp: No connection could be made because the target machine actively refused it.. Are you trying to connect to a TLS-enabled daemon without TLS?

    boot2docker start 之后需要设置下面三个环境变量:DOCKER_HOST, DOCKER_CERT_PATH, DOCKER_TLS_VERIFY

    如果在 windows 下 boot2docker 啟動成功之後會有下面的提示:

    To connect the Docker client to the Docker daemon, please set:
    If you are running inside Windows Command Prompt (cmd.exe), copy and paste the
    following commands to your terminal to set the environment variables:
        set DOCKER_HOST=tcp://192.168.59.103:2376
        set DOCKER_CERT_PATH=C:\Users${user}\.boot2docker\certs\boot2docker-vm
        set DOCKER_TLS_VERIFY=1
    
    If you are running inside PowerShell, copy or paste the following commands
    to your shell or run "boot2docker shellinit | Invoke-Expression" to set the
    environment variables:
        $Env:DOCKER_HOST = "tcp://192.168.59.103:2376"
        $Env:DOCKER_CERT_PATH = "C:\Users${user}\.boot2docker\certs\boot2docker-vm"
        $Env:DOCKER_TLS_VERIFY = "1"
    

    將上面提示的那三個環境變數複製執行一遍就可以,例如在 windows 的 cmd 中執行:

    set DOCKER_HOST=tcp://192.168.59.103:2376
    set DOCKER_CERT_PATH=C:\Users${user}\.boot2docker\certs\boot2docker-vm
    set DOCKER_TLS_VERIFY=1
