Docker容器下安装Kong网关

1 官网说明：

这是一个简单的示例，显示了如何将Kong容器连接到Cassandra或PostgreSQL容器。

1. 创建一个Docker网络

   您将需要创建一个自定义网络，以使容器能够发现彼此并进行通信。在此示例中kong-net为网络名称，您可以使用任何名称。

    $ docker network create kong-net

2. 启动你的数据库

   如果您想使用Cassandra容器：

    $ docker run -d --name kong-database 
                  --network=kong-net 
                  -p 9042:9042 
                  cassandra:3

   如果您想使用PostgreSQL容器：

    $ docker run -d --name kong-database 
                  --network=kong-net 
                  -p 5432:5432 
                  -e "POSTGRES_USER=kong" 
                  -e "POSTGRES_DB=kong" 
                  -e "POSTGRES_PASSWORD=kong" 
                  postgres:9.6

3. 准备数据库

   使用临时Kong容器运行迁移：

    $ docker run --rm 
        --network=kong-net 
        -e "KONG_DATABASE=postgres" 
        -e "KONG_PG_HOST=kong-database" 
        -e "KONG_PG_PASSWORD=kong" 
        -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" 
        kong:latest kong migrations bootstrap

   在上面的示例中，同时配置了Cassandra和PostgreSQL，但是您应该KONG_DATABASE使用cassandra或更新环境变量 postgres。

   Kong <0.15的注意事项：Kong版本低于0.15（最大0.14）时，请使用up子命令代替bootstrap。还要注意，Kong <0.15时，永远不要同时运行迁移。一次只能有一个Kong节点执行迁移。对于0.15、1.0及更高版本，此限制被取消。

4. 刚开始

   运行迁移并准备好数据库后，启动将连接到数据库容器的Kong容器，就像临时迁移容器一样：

    $ docker run -d --name kong 
        --network=kong-net 
        -e "KONG_DATABASE=postgres" 
        -e "KONG_PG_HOST=kong-database" 
        -e "KONG_PG_PASSWORD=kong" 
        -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" 
        -e "KONG_PROXY_ACCESS_LOG=/dev/stdout" 
        -e "KONG_ADMIN_ACCESS_LOG=/dev/stdout" 
        -e "KONG_PROXY_ERROR_LOG=/dev/stderr" 
        -e "KONG_ADMIN_ERROR_LOG=/dev/stderr" 
        -e "KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl" 
        -p 8000:8000 
        -p 8443:8443 
        -p 127.0.0.1:8001:8001 
        -p 127.0.0.1:8444:8444 
        kong:latest

5. 使用kong

   Kong正在运行：

    $ curl -i http://localhost:8001/

 安装如下
