按照下面这个文档进行安装

设置网络

$ docker network create kong-net

安装数据库，使用postgres

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

准备kong数据

$ 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

启动kong，设置postgres数据库

$ 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:latest

Kong is running:
$ curl -i http://localhost:8001/

UI 安装

docker run -d --name kong-dashboard \
    --network=kong-net \
    --link kong:kong \
    -p 8080:8080 \
    pgbi/kong-dashboard:v2 migrations up

这里需要配置link，不配置的话，在ui上连接kong时会报错，找不到kong server。

进入ui : http://localhost:8080
kong node = http://kong:8001
