创建confd目录

conf.d 目录中是应用的配置文件定义
templates 目录中是应用的模版文件
confd.toml 是confd本身的配置文件
mkdir -p /etc/confd/{conf.d,templates}

root@747f14c47586:/etc/confd/conf.d# cat nginx.toml 
[template]
src = "nginx.conf.tmpl"
dest = "/etc/nginx/conf.d/default.conf"
keys = [ "/netm/url" ]
check_cmd = "/etc/init.d/nginx configtest"
reload_cmd = "/etc/init.d/nginx reload"

root@747f14c47586:/etc/confd/templates# cat nginx.conf.tmpl 
server {
        listen 80;
        location /netm/index.jsp {
                rewrite ^(.*)$ {{ getv "/netm/url" }} redirect;
                expires 1s;
