docker run hello-world 遇到错误消息 - error during connect
執(zhí)行命令行:
docker run hello-world
遇到錯誤消息:
docker: error during connect: This error may indicate that the docker daemon is not running.: Post “http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/create”: open //./pipe/docker_engine: The system cannot find the file specified.
See ‘docker run --help’.
錯誤消息里已經(jīng)解釋清楚原因了:docker daemon 沒有啟動。
進到文件夾:C:\Program Files\Docker\Docker
執(zhí)行 DockerCli -switchDaemon 之后,
任務(wù)欄里看到這個 icon:
之后執(zhí)行成功:
這條消息打印的背后,執(zhí)行了這些事情:
(1) The Docker client contacted the Docker daemon.
Docker 客戶端同 docker daemon 連接
(2) The Docker daemon pulled the “hello-world” image from the Docker Hub.
(windows-amd64, nanoserver-1809)
因為這個命令是第一次執(zhí)行,Docker daemon 從 docker hub 網(wǎng)站,將 hello-world 鏡像下載到本地。
(3) The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading.
Docker daemon 基于下載好的鏡像,創(chuàng)建一個新的容器,后者運行鏡像,產(chǎn)生一條輸出消息
(4) The Docker daemon streamed that output to the Docker client, which sent it to your terminal.
Docker daemon 將輸出發(fā)給 docker 客戶端,后者再發(fā)到 Windows 控制臺。
