/etc/docker/daemon.json 是 docker 的配置文件，默認是沒有的，需要我們手動創建，可配置項如下：

[root@localhost ~]$ vim /etc/docker/daemon.json {"authorization-plugins": [],"data-root": "", # 設置docker運行時的根目錄"dns": [], # 設置容器的DNS地址"dns-opts": [], # 設置容器的/etc/resolv.conf文件"dns-search": [],"exec-opts": [],"exec-root": "","experimental": false,"features": {},"storage-driver": "","storage-opts": [],"labels": [],"live-restore": true,"log-driver": "json-file","log-opts": {"max-size": "10m","max-files":"5","labels": "somelabel","env": "os,customer"},"mtu": 0,"pidfile": "", # 設置docker守護進程的PID文件"cluster-store": "", "cluster-store-opts": {},"cluster-advertise": "","max-concurrent-downloads": 3,"max-concurrent-uploads": 5,"default-shm-size": "64M","shutdown-timeout": 15,"debug": true, # 是否以debug模式啟動docker"hosts": [], # 設置容器的hosts"log-level": "","tls": true,"tlsverify": true,"tlscacert": "","tlscert": "","tlskey": "","swarm-default-advertise-addr": "","api-cors-header": "","selinux-enabled": false, # 設置是否支持SELinux"userns-remap": "","group": "","cgroup-parent": "","default-ulimits": {"nofile": {"Name": "nofile","Hard": 64000,"Soft": 64000}},"init": false,"init-path": "/usr/libexec/docker-init","ipv6": false,"iptables": false,"ip-forward": false, "ip-masq": false,"userland-proxy": false,"userland-proxy-path": "/usr/libexec/docker-proxy","ip": "0.0.0.0","bridge": "","bip": "","fixed-cidr": "","fixed-cidr-v6": "","default-gateway": "","default-gateway-v6": "","icc": false,"raw-logs": false,"allow-nondistributable-artifacts": [],"registry-mirrors": [], # 設置鏡像加速地址"seccomp-profile": "","insecure-registries": [], # 設置docker的私有倉庫地址"no-new-privileges": false,"default-runtime": "runc","oom-score-adjust": -500,"node-generic-resources": ["NVIDIA-GPU=UUID1", "NVIDIA-GPU=UUID2"],"runtimes": {"cc-runtime": {"path": "/usr/bin/cc-runtime"},"custom": {"path": "/usr/local/bin/my-runc-replacement","runtimeArgs": ["--debug"]}},"default-address-pools":[{"base":"172.80.0.0/16","size":24},{"base":"172.90.0.0/16","size":24}] }
