修改runtimes,重启docker报错
unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag a...meArgs:[]]])
原因分析:是因为/etc/docker/daemon.json中配置的runtimes与/usr/lib/systemd/system/docker.service中的runtimes冲突
/etc/docker/daemon.json
{
"runtimes": {
"nvidia": {
"path": "nvidia-container-runtime",
"runtimeArgs": []
}
}
}
