# Executing docker install script, commit: 93d2499759296ac1f9c510605fef85052a2c32be Warning: the "docker" command appears to already exist on this system. If you already have Docker installed, this script can cause trouble, which is why we're displaying this warning and provide the opportunity to cancel the installation. If you installed the current Docker package using this script and are using it again to update Docker, you can safely ignore this message. You may press Ctrl+C now to abort this script. + sleep 20 + sh -c 'yum install -y -q yum-utils' http://mirrors.cloud.aliyuncs.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirrors.cloud.aliyuncs.com; Unknown error" Trying other mirror. http://mirrors.cloud.aliyuncs.com/epel/7/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirrors.cloud.aliyuncs.com; Unknown error" Trying other mirror. http://mirrors.cloud.aliyuncs.com/centos/7/extras/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirrors.cloud.aliyuncs.com; Unknown error" Trying other mirror. http://mirrors.cloud.aliyuncs.com/centos/7/updates/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirrors.cloud.aliyuncs.com; Unknown error" Trying other mirror.
