ApiSix的docker 容器化部署及使用

⼀．etcd安装
Docekr安装Etcd
环境准备
此处安装，是利⽤下载的 etcd 源⽂件，利⽤ docker build 构建完整镜像，具体操作如下：
1.环境准备
1.1. 新建⽂件夹
在磁盘某个路径下新建⼀个⽂件夹，⽤处操作 Dockerfile 和 源⽂件。
演⽰中的路径在 /data/docker-compose/etcd ，如特殊说明，否则都在此路径，以下简称
ETCD_HOME
1.2. 下载

在 ETCD_HOME 中下载最新版本，官⽅下载地址如下： wget https://github.com/etcd-io/etcd/

1.3. ⽂件解压
解压⽂件 tar.gz 得到 etcd-v3.4.20-linux-amd64 ⽂件夹。

tar -zxvf etcd-v3.4.20-linux-amd64.tar.gz

1.4. ⽂件拷⻉
在 etcd-v3.4.20-linux-amd64 ⽂件夹下，有 etcd 和 etcdctl 两个⽂件，拷⻉⾄与 etcd-v3.4.20-linuxamd64 同⼀级。

cp etcd-v3.4.20-linux-amd64/etcd etcd-v3.4.20-linux-amd64/etcdctl .

2.安装
2.1Dockerfile编写

FROM alpine:latest
ADD etcd /usr/local/bin/
ADD etcdctl /usr/local/bin/
RUN mkdir -p /var/etcd/
RUN mkdir -p /var/lib/etcd/
RUN echo 'hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4' >> /etc/nsswitch.conf
EXPOSE 2379 2380
CMD ["/usr/local/bin/etcd"]

2.2构建镜像并推送

//打包为docker镜像
docker build -t 阿里云镜像仓库地址/xxxx/etcd:5.1.Z .
//将docker镜像推送到阿里云上
docker push  阿里云镜像仓库地址/xxxxx/etcd:5.1.Z

2.3启动镜像

docker run -d -v /usr/share/ca-certificates/:/etc/ssl/certs -p 4001:4001 -p 2380:2380 -p 2379:2379 \
 --name etcd 阿里云镜像仓库地址/xxxx/etcd:5.1.Z /usr/local/bin/etcd \
 -name etcd0 \
 -advertise-client-urls http://182.182.33.103:2379 \
 -listen-client-urls http://0.0.0.0:2379 \
 -initial-advertise-peer-urls http://0.0.0.0:2380 \
 -listen-peer-urls http://0.0.0.0:2380 \
 -initial-cluster-token etcd-cluster-1 \
 -initial-cluster etcd0=http://0.0.0.0:2380 \
 -initial-cluster-state new

name: 节点名称
advertise-client-urls: 知客户端url, 也就是服务的url 就是etcd部署在那台机器上就写那台的ip
initial-advertise-peer-urls: 告知集群其他节点url
listen-peer-urls: 监听URL，用于与其他节点通讯
initial-cluster-token: 集群的ID
initial-cluster: 集群中所有节点

3.下载并安装etcd-manager（etcd的可视化客户端）

https://etcdmanager.io/

二.安装apisix
1.首先在创建如下文件夹和文件:
文件地址：
/opt/apisix/apisix-conf/
上传config.yaml到上面的文件夹下
内容：主要修改的是etcd:host部分

2.执行下载和启动docker的命令

docker run -d --name apisix -p 9080:9080 -p 9443:9443  -p 9180:9180 -v /opt/apisix/apisix-conf/config.yaml:/usr/local/apisix/conf/config.yaml:ro apache/apisix:latest

下面这是web端命令：

docker run -d --name apisix-dashboard -p 9000:9000 -v /opt/apisix/dashboard_conf/conf.yaml:/usr/local/apisix-dashboard/conf/conf.yaml apache/apisix-dashboard:3.0.0-alpine

容器启动成功后访问ApiSix仪表台，如下图成功访问

3.apisix代理地址的使用
配置上游：

填写名称、可选择上游类型。这里选择的是节点，当然可以选择服务发现，但是需要配置。

创建完上游后可以创建路由

点击下一步选择上游服务

然后一直下一步到提交。
之后就可以打开postman进行测试了。
默认访问的端口是9080

apisix相关文档:

https://apisix.apache.org/zh/docs/apisix/getting-started/README/

https://apisix.apache.org/zh/docs/

三.代理轮询的使用
1.上游类型为节点
配置上游。

上述目标节点的配置其实是同一个后端服务的，只不过我在一台机器上无法使用相同的端口所以修改了一下端口，这个的含义就是我的一个后端服务做了集群部署，这样配置就可以轮询去访问多台服务器上的同一个后端服务。
上游配置完可以配置服务也可以直接配置路由,当配置服务后再配置路由绑定服务选择自己创建的服务。

2.服务发现的形式(这里以nacos注册中心为例)
服务发现的文章可以看看这篇:https://www.aneasystone.com/archives/2023/03/apisix-service-discovery.html
在/opt/apisix/apisix-conf/
的config.yaml文件中添加nacos配置
整体配置：

 nacos:
    host:
      - "http://nacos:[email protected]:8848"
    prefix: "/nacos/v1/"
    fetch_interval: 30    # default 30 sec
    weight: 100           # default 100
    timeout:
      connect: 2000       # default 2000 ms
      send: 2000          # default 2000 ms
      read: 5000          # default 5000 ms

简洁配置：

discovery:
  nacos:
    host:
      - "http://193.193.173.721:8848"

官网文档地址:https://apisix.apache.org/zh/docs/apisix/discovery/nacos/
配置完成后重启apisix服务
配置上游

上游配置完可以配置服务也可以直接配置路由。
nacos截图

分别访问不同服务器上的同一个服务，发现可以做到轮询访问。
