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": []
        }
    }
}
