daemon.json 小例子


{"registry-mirrors": ["http://docker.mirrors.ustc.edu.cn"],"log-driver":"json-file","log-opts": {"max-size":"500m", "max-file":"3"},"data-root":"/docker/libdocker"
}

后续启动命令

vim /etc/docker/daemon.json
systemctl daemon-reload
systemctl restart docker

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

可以修改的


sed -i 's#ExecStart.*#ExecStart=/usr/bin/dockerd  -H fd:// --containerd=/run/containerd/containerd.sock -g /docker/libdocker #g' /usr/lib/systemd/system/docker.service

{
“registry-mirrors”: [“http://docker.mirrors.ustc.edu.cn”],
“log-driver”:“json-file”,
“log-opts”: {“max-size”:“500m”, “max-file”:“3”},
“data-root”:“/docker/libdocker”
}

vim /etc/docker/daemon.json

systemctl daemon-reload

systemctl restart docker

sed -i ‘s#ExecStart.*#ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -g /docker/libdocker #g’ /usr/lib/systemd/system/docker.service

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF’
{
“registry-mirrors”: [“https://k19o1tfu.mirror.aliyuncs.com”]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

docker run启动

设置类型	Description
`shared`	任何挂载了此目录的容器都会双向和宿主机实时更新,作用范围当前目录,不包括子目录
`slave`	任何挂载了此目录的容器都会收到实时更新,更新是单向的; 宿主机到容器,作用范围当前目录,不包括子目录
`private`	任何挂载了此目录的容器都不会收到实时更新
`rshared`	同 shared, 作用范围也包括子目录
`rslave`	同 slave, 作用范围也包括子目录
`rprivate`	同 private, 作用范围也包括子目录
