kong 實際上就是一個ngnix，通過增加外掛程式的方式對請求做前置處理，主要是授權一.安裝kong 服務；https://konghq.com/install/  提供多種方式的安裝，建議使用docker進行安裝：（centos的tar包的安裝方式，建議使用node.js 安裝 kong-dashboard）最新版本的kong不支援kong-dashboard，所以我使用的版本是 v0.13.1 docker 安裝 kong服務，  https://docs.konghq.com/install/docker/

1. Create a Docker network

   You will need to create a custom network to allow the containers to discover and communicate with each other. In this example kong-net is the network name, you can use any name.

   $ docker network create kong-net

2. Start your database

   If you wish to use a Cassandra container:

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

   If you wish to use a PostgreSQL container:

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

3. Prepare your database

   Run the migrations with an ephemeral Kong container:

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

   In the above example, both Cassandra and PostgreSQL are configured, but you should update the KONG_DATABASE environment variable with either cassandra or postgres.

   Note: migrations should never be run concurrently; only one Kong node should be performing migrations at a time.

4. Start Kong

   When the migrations have run and your database is ready, start a Kong container that will connect to your database container, just like the ephemeral migrations container:

   $ docker run -d --name kong     --network=kong-net     -e "KONG_DATABASE=postgres"     -e "KONG_PG_HOST=kong-database"     -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 8001:8001     -p 8444:8444     kong:0.13.1-centos

5. Use Kong

   Kong is running:

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

# Start Kong Dashboarddocker run --rm -p 8080:8080 pgbi/kong-dashboard start --kong-url http://kong:8001# Start Kong Dashboard on a custom portdocker run --rm -p [port]:8080 pgbi/kong-dashboard start --kong-url http://kong:8001# Start Kong Dashboard with basic authdocker run --rm -p 8080:8080 pgbi/kong-dashboard start   --kong-url http://kong:8001 \   --basic-auth user1=password1 user2=password2# See full list of start optionsdocker run --rm -p 8080:8080 pgbi/kong-dashboard start --help

 注意點 如果kong的服務也是docker起的， kong-url的 address 應該為內網地址，localhost是無法串連的 如果使用了內網地址還無法串連，嘗試以下代碼：

1. Create bridge network
   docker network create my-net
2. Add Kong container to it
   docker network connect my-net kong
3. Provide network info when you run kong-dashboard
   docker run --rm --network my-net -p 8080:8080 pgbi/kong-dashboard start --kong-url http://kong:8001
