docker - Kong:缺少用于连接的数据库

Question

我试图为我的公司成立Kong，所以我遵循Kong文档的指示。
首先我运行以下命令:

docker network create kong-net

然后此命令:

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

根据文档，下一步是使用此命令运行迁移

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

但它一直给我这个错误

Error: missing database for connect

我哪里做错了 ？

Answer 1

请遵循这个
步骤1

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

第2步

docker run --rm \
    --link kong-database:kong-database \
    -e "KONG_DATABASE=postgres" \
    -e "KONG_PG_HOST=kong-database" \
    -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" \
    kong kong migrations up

步骤:3

docker run -d --name kong \
    --link kong-database:kong-database \
    -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

如果您没有任何问题，也可以使用docker-compose
更新了

version: "2"

services:
  kong-database:
    image: postgres:9.6
    container_name: kong-database
    ports:
      - 5432:5432
    environment:
      POSTGRES_DB: kong
      POSTGRES_USER: kong
      POSTGRES_PASSWORD: kong

  kong:
    image: kong:latest
    command: "kong migrations bootstrap"
    restart: always
    links:
      - kong-database:kong-database
    ports:
      - 8000:8000
      - 8443:8443
      - 8001:8001
      - 7946:7946
      - 7946:7946/udp
    environment:
      - KONG_DATABASE=postgres
      - KONG_PG_HOST=kong-database
      - KONG_PG_PASSWORD=kong
      - KONG_PG_USER=kong
