通常我们修改Docker的守护进程的一些特性是通过在/lib/systemd/system/docker.service这个配置文件的ExecStart后面增加启动参数,但是如果要设置的特性比较多,显然这个参数会很长。所以还是通过修改配置文件更加直观和方便。
配置文件在哪里:
在我们使用的这个Docker版本中,默认的配置文件是/etc/docker/daemon.json,但是这个文件并不存在,不过这个目录是存在的。
既然没有那个文件,我们就建立一个。这个文件的格式是JSON格式,其实没有什么难得,只要了解这个格式就可以写。大体格式如下:
[ { "ITME1": "VALUE", "ITEM2": { "ITME2-1": "VALUE", "ITEM2-2": "VALUE", "ITEM2-3": { "ITEM2-3-1": "VALUE", } } } ]
你只要知道格式,具体的值需要的时候再查询就行。下面是一个全的LINUX平台下的配置文件,来源于官网:
{ "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": "" "registry-mirrors": ["https://y49g0r41.mirror.aliyuncs.com"] }
配置的时候你只需要挑选你需要的,不用全写进去。然后在dockerd命令后面使用--confige-file 知名配置文件就好,重复的就被覆盖了,不重复的则保持默认。
