Confd生成nginx配置示例

官方网站:

http://www.confd.io/

环境:

CentOS7.2

go-1.7

编译安装

https://github.com/kelseyhightower/confd
https://github.com/kelseyhightower/confd/blob/master/docs/quick-start-guide.md

1.go(>=1.6)环境

2.下载并安装 

$ mkdir -p $GOPATH/src/github.com/kelseyhightower 

$ git clone https://github.com/kelseyhightower/confd.git $GOPATH/src/github.com/kelseyhightower/confd 

$ cd $GOPATH/src/github.com/kelseyhightower/confd 

$ ./build

 二进制包

curl -sSL https://github.com/kelseyhightower/confd/releases/download/v0.11.0/confd-0.11.0-linux-amd64 -o /usr/local/sbin/confd

chmod +x /usr/local/sbin/confd

管理nginx配置

1.挑选后端

以consol为例

curl -X PUT -d 'myapp' http://localhost:8500/v1/kv/myapp/subdomain

curl -X PUT -d '10.0.1.100:80' http://localhost:8500/v1/kv/myapp/upstream/app1

curl -X PUT -d '10.0.1.101:80' http://localhost:8500/v1/kv/myapp/upstream/app2

curl -X PUT -d 'yourapp' http://localhost:8500/v1/kv/yourapp/subdomain

curl -X PUT -d '10.0.1.102:80' http://localhost:8500/v1/kv/yourapp/upstream/app1

curl -X PUT -d '10.0.1.103:80' http://localhost:8500/v1/kv/yourapp/upstream/app2

2.创建confdir

mkdir -p /etc/confd/{conf.d,templates}

3.创建模板配置文件

cat >/etc/confd/conf.d/myapp-nginx.toml <<EOF

[template]

prefix = "/myapp"

src = "nginx.tmpl"

dest = "/tmp/myapp.conf"

owner = "nginx"

mode = "0644"

keys = [

  "/subdomain",

  "/upstream",

]

EOF

cat >/etc/confd/conf.d/yourapp-nginx.toml <<EOF

[template]

prefix = "/yourapp"

src = "nginx.tmpl"

dest = "/tmp/yourapp.conf"

owner = "nginx"

mode = "0644"

keys = [

  "/subdomain",

  "/upstream",

]

EOF

4.创建模板

cat >/etc/confd/templates/nginx.tmpl <<'EOF'

upstream {{getv "/subdomain"}} {

{{range getvs "/upstream/*"}}

    server {{.}};

{{end}}

}

server {

    server_name  {{getv "/subdomain"}}.example.com;

    location / {

        proxy_pass        http://{{getv "/subdomain"}};

        proxy_redirect    off;

        proxy_set_header  Host             $host;

        proxy_set_header  X-Real-IP        $remote_addr;

        proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;

   }

}

EOF

5.生成模板

confd -onetime -backend consul -node 127.0.0.1:8500
