我confd用来根据我的环境渲染我的配置文件

$ ls -R /etc/confd
/etc/confd/:
conf.d  templates

/etc/confd/conf.d:
my_app.toml

/etc/confd/templates:
my_app.tmpl

我的配置：

$ cat /etc/confd/conf.d/my_app.toml
[template]
src = "my_app.tmpl"
dest = "/etc/nginx/sites-enabled/my_app.conf"

$ cat /etc/confd/templates/my_app.tmpl
# ...
    location @rewriteapp {
        rewrite ^(.*)$ /{{ getenv "/app/entry/point" }}/$1 last;
    }
# ...

confd运行良好

$ export APP_ENTRY_POINT="app_dev.php"
$ confd -onetime -backend env
2016-04-15T13:54:29Z 1c682a040707 /usr/local/bin/confd[44]: INFO Backend set to env

但是生成的文件没有解析变量

$ cat /etc/nginx/sites-enabled/my_app.conf
# ...
    location @rewriteapp {
        rewrite ^(.*)$ //$1 last;
#                       ^- I should have app_dev.php between the `//`
    }
# ...
  • 我在这里做错了吗？
  • 我该如何调试呢？

与记录的不同，confd(0.11.0)getenv函数似乎并不期望环境变量为 path /app/entry/point。

环境变量确实保持原样：APP_ENTRY_POINT

所以模板应该简单地说：

$ cat /etc/confd/templates/my_app.tmpl
# ...
    location @rewriteapp {
        rewrite ^(.*)$ /{{ getenv "APP_ENTRY_POINT" }}/$1 last;
    }
# ...

有-debug&-verbose选项可以检查发生了什么
