Confd user name is empty

问题：Confd 启动时报 "user name is empty"的错

后端存储:etcdv3 (开启Basic Auth认证)
confd版本:confd-0.16.0-linux-amd64

这个报错会在以下三种情况下出现：

1、confd启动时没有加-username 、-password和-basic-auth选项

confd -log-level debug -watch -backend etcdv3 -node http://127.0.0.1:2379

2、confd启动时只加了-username 、-password选项，没加-basic-auth

confd -log-level debug -watch -backend etcdv3 -node http://127.0.0.1:2379  -username root -password fac3f780831f8._

3、confd启动参数放在配置文件中时，基本认证写成了basic-auth=true,应该是basic_auth=true。

这有点奇怪，按道理关键字无论是终端下和配置文件中都是一样的

confd -config-file=/etc/confd/confd.conf

/etc/confd/confd.conf:

backend="etcdv3"
nodes=[
 "http://127.0.0.1:2379",
]
watch=true
prefix="/"
confdir="/etc/confd"
log-level="info"
basic-auth=true
username="root"
password="fac3f780831f8._"

解决方案

对于1和2：启动时同时添加-basic-auth、-username和-password三个选项

confd -log-level debug -watch -backend etcdv3 -node http://127.0.0.1:2379 -basic-auth -username root -password fac3f780831f8._

对于3：将配置文件中的basic-auth改成basic_auth
/etc/confd/confd.conf:

backend="etcdv3"
nodes=[
 "http://127.0.0.1:2379",
]
watch=true
prefix="/"
confdir="/etc/confd"
log-level="info"
basic_auth=true
username="root"
password="fac3f780831f8._"

成功运行的效果：

至此问题解决！
