First, the status quo 1, the default does not have this configuration file, manually create one. 2. The operations we are currently using are in the section "Docker in-depth 2-storage-driven use Devicemapper (DIRECT-LVM) mode", Here's how we do it:---------------------------------------adjustment  daemon.json  configuration: [[email protected] ~]#  cat /etc/docker/daemon.json{     "Storage-driver":  "Devicemapper",      "storage-opts": [         "dm.thinpooldev=/dev/ Mapper/docker-thinpool ",        " Dm.use_deferred_removal=true ",          "Dm.use_deferred_deletion=true"     ]}----------- ----------------------------defines the value of  storage-driver . Then restart the service: [[Email protected] ~]# systemctl restart docker && systemctl  status docker -l the benefits of doing this: when adjusting the configuration, it's not necessary to modify the parameters of the  docker.service, which is more clearly and rationally managed by the configuration file. Second, explore 1, Linux a complete configuration example {     "Api-cors-header":  "",     "AuthorizAtion-plugins ": [],    " Bip ": " ",    " Bridge ": " ",      "Cgroup-parent":  ",    " Cluster-store ": " ",      "cluster-store-opts": {},     "cluster-advertise":  "",      "Debug": true,     "Default-gateway":  ",    " Default-gateway-v6 ": " ",    " Default-runtime ": " Runc ",    " Default-ulimits ": {},    " Disable-legacy-registry ": false,      "DNS": [],     "dns-opts": [],     "Dns-search":  [] ,     "exec-opts": [],     "Exec-root":  "",      "FIXED-CIDR":  ",    " fixed-cidr-v6 ": " ",    " graph ":   "",      " Group ": " ",    " hosts ": [],    " ICC ": false,      "insecure-registries": [],     "IP":  "0.0.0.0",      "iptables": false,     "IPv6": false,     " Ip-forward ": false,    " IP-MASQ ": false,    " labels ":  [ ],     "Live-restore": true,     "Log-driver":  "",      "Log-level":  ",    " log-opts ": {},    " Max-concurrent-downloads ": 3,    " Max-concurrent-uploads ": 5,      "MTU": 0,     "Oom-score-adjust": -500,     "Pidfile":   ",    " Raw-logs ": false,    " registry-mirrors ":  [],      "runtimes": {        " Runc ": {              "path":  "Runc"         },          "Custom": {              "path":  "/usr/local/bin/my-runc-replacement",              "Runtimeargs": [                  "--debug"              ]        }    },      "selinux-enabled": false,     "Storage-driver":  "",      "storage-opts": [],     "swarm-default-advertise-addr":  "",      "TLS":  true,     "Tlscacert":  ",    " Tlscert ": " ",      "Tlskey":  ",    " tlsverify ": true,    " Userland-proxy ": false,    " Userns-remap ": "} above is a sample configuration provided by the official website, which we can refer to, optionally configuring some of the content. 2. How to configure  registry  related parameters involves the following 2 parameters:     "Insecure-registries": [],      "registry-mirrors":  [], configuration example: [[email protected] ~]# cat /etc/docker/ daemon.json{     "Storage-driver":  "Devicemapper",     " Storage-opts ": [        " dm.thinpooldev=/dev/mapper/ Docker-thinpool ",        " Dm.use_deferred_removal=true ",          "Dm.use_deferred_deletion=true"     ],      "Registry-mirrors":  [         "http://m.hub.test.com"     ],      " Insecure-registries ": [        " hub.test.com "     ]}        ZYXW, reference 1, docshttps://docs.docker.com/engine/reference/ Commandline/dockerd/#/linux-configuration-file
