Stand-alone mode

开启 Stand-alone 模式的 APISIX 节点,将不再使用默认的 etcd 作为配置中心。

这种方式比较适合两类用户:

  1. kubernetes(k8s):声明式 API 场景,通过全量 yaml 配置来动态更新修改路由规则。
  2. 不同配置中心:配置中心的实现有很多,比如 Consul 等,使用全量 yaml 做中间转换桥梁。

APISIX 节点服务启动后会立刻加载 conf/apisix.yaml 文件中的路由规则到内存,并且每间隔一定时间(默认 1 秒钟),都会尝试检测文件内容是否有更新,如果有更新则重新加载规则。

注意:重新加载规则并更新时,均是内存热更新,不会有工作进程的替换过程,是个热更新过程。

由于目前 Admin API 都是基于 etcd 配置中心解决方案,当开启 Stand-alone 模式后, Admin API 将不再被允许使用。

只有当 APISIX 的角色设置为 data plane 时,才能开启 Stand-alone 模式。通过设置 deployment.roledata_plane,设置 deployment.role_data_plane.config_provideryaml 即可启用 Stand-alone 模式。

参考下面示例:

deployment:
role: data_plane
role_data_plane:
config_provider: yaml

如何配置规则#

所有的路由规则均存放在 conf/apisix.yaml 这一个文件中,APISIX 会以每秒(默认)频率检查文件是否有变化,如果有变化,则会检查文件末尾是否能找到 #END 结尾,找到后则重新加载文件更新到内存。

下面就是个最小的示例:

routes:
-
uri: /hello
upstream:
nodes:
"127.0.0.1:1980": 1
type: roundrobin
#END

注意:如果 conf/apisix.yaml 末尾不能找到 #END,那么 APISIX 将不会加载这个文件规则到内存。

配置 Router#

单个 Router:

routes:
-
uri: /hello
upstream:
nodes:
"127.0.0.1:1980": 1
type: roundrobin
#END

多个 Router:

routes:
-
uri: /hello
upstream:
nodes:
"127.0.0.1:1980": 1
type: roundrobin
-
uri: /hello2
upstream:
nodes:
"127.0.0.1:1981": 1
type: roundrobin
#END

配置 Router + Service#

routes:
-
uri: /hello
service_id: 1
services:
-
id: 1
upstream:
nodes:
"127.0.0.1:1980": 1
type: roundrobin
#END

配置 Router + Upstream#

routes:
-
uri: /hello
upstream_id: 1
upstreams:
-
id: 1
nodes:
"127.0.0.1:1980": 1
type: roundrobin
#END

配置 Router + Service + Upstream#

routes:
-
uri: /hello
service_id: 1
services:
-
id: 1
upstream_id: 2
upstreams:
-
id: 2
nodes:
"127.0.0.1:1980": 1
type: roundrobin
#END

配置 Plugins#

# 列出的插件会被热加载并覆盖掉启动时的配置
plugins:
- name: ip-restriction
- name: jwt-auth
- name: mqtt-proxy
stream: true # stream 插件需要设置 stream 属性为 true
#END

启用 SSL#
