配置docker所在的服务器，使得可通过http远程访问操作服务器docker
环境
Linux：CentOS release 6.10 (Final)
docker: 1.7
环境很重要，CentOS 6和CentOS 7的配置文件路径是不一样的，有些配置文件找不到，配置也不一样！！！
本篇说的是CentOS6

配置方法
1修改配置文件/etc/sysconfig/docker里的配置
vim /etc/sysconfig/docker
把原来的other_args=
改为
other_args="-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375"
图片.png
网上说的啥配置DOCKER_OPTS="-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375"的都没用
2 重启docker使配置生效
service docker restart
即使此时你有docker镜像正在运行，也可以重启docker的，不影响，不会把你正在运行的docker断掉的
检查下2375端口是不是在监听状态，有就对了，外网访问，防火墙注意下
netstat -nap | grep 2375

3 浏览器访问服务器的docker
http://xxxxx.com:2375/info
2375端口是你配置的端口，可以随便改的

HTTP API 如何创建镜像？
官网API：https://docs.docker.com/engine/api/v1.29/#section/Versioning
1.25版本之后的api样式和原来不一样了，最新的更好看点
docker版本与api版本对应关系
我应该用1.26的

例子：
前提 Content-Type: application/json
1创建容器
POST /containers/create
创建镜像其实主要是配置HostConfig
配置10000端口映射docker内部的8080端口，得配ExposedPorts属性
配置挂载目录/tmp:/tmp，后面是docker内部的目录，且必须都是绝对路径
官方解释：host-src:container-dest to bind-mount a host path into the container. Both host-src, and container-dest must be an absolute path.

2容器重命名
我在创建的时候没找到直接命名的参数，所以只能先创建，再重命名
POST
http://192.168.0.243:2375/v1.13/containers/658b5801d60ecd4dd1fc2a9416bbdf626f6fbac5f20db432c910e01dd41e2d30/rename?name=tomcat5000
3查看容器详情
GET
http://192.168.0.243:2375/v1.25/containers/tomcat5000/json
结果
