Guacamole Docker 版本 - 必须登录 mySQL 才能工作

Question

我在 OCI 上的 Oracle Linux 8 上很好地安装了 Guacamole。可以在 https://github.com/timyshark/guacamole 找到存储库。

总结：

docker-compose.yaml

：

# import .env file from volt
# Generate ./initdb.sql : $ mkdir initdb && docker run --rm guacamole/guacamole /opt/guacamole/bin/initdb.sh --mysql > ./initdb/initdb.sql

# networks
# create a network 'guacamole_net' in mode 'bridged'
networks:
  guac-net:
driver: bridge
  haproxy_net:
external: true

# services
services:
  # guacd
  guacd:
container_name: guac-guacd
image: guacamole/guacd
networks:
  guac-net:
restart: always

  # mysql
  mysql:
container_name: guac-mysql
environment:
  MYSQL_ROOT_PASSWORD: '${MYSQL_ROOT_PASSWORD}'
  MYSQL_DATABASE: '${MYSQL_DATABASE}'
  MYSQL_USER: '${MYSQL_USER}'
  MYSQL_PASSWORD: '${MYSQL_PASSWORD}'
image: mysql:oraclelinux8
networks:
  guac-net:
restart: always
volumes:
- ./initdb:/docker-entrypoint-initdb.d

  # guacamole
  guacamole:
container_name: guac-guacamole
depends_on:
- guacd
- mysql
environment:
  GUACD_HOSTNAME: guacd
  MYSQL_HOSTNAME: mysql
  MYSQL_DATABASE: '${MYSQL_DATABASE}'
  MYSQL_USER: '${MYSQL_NAME}'
  MYSQL_PASSWORD: '${MYSQL_PASSWORD}'
  MYSQL_SSL_MODE: disabled
image: guacamole/guacamole
ports:
- "8080:8080"
links:
- guacd
networks:
  - guac-net
restart: always

一切正常，除了第一个

docker compose up

我收到错误

我不确定如何解决问题，或者按照日志中的说明更改驱动程序。

如果我在进入 http://guacamole-server:8080/guacamole 后就使用用户 guacamole/password 登录 mysql 容器

$docker exec -it guac-mysql bash
#mysql -u guacamole guacamoledb -p

这个设置对我来说可靠：

version: "3.7"

services:
  guacd:
    image: guacamole/guacd
    restart: always

  mysql:
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}
      MYSQL_DATABASE: ${MYSQL_DATABASE}
      MYSQL_USER: ${MYSQL_USER}
      MYSQL_PASSWORD: ${MYSQL_PASSWORD}
    healthcheck:
      test: ["CMD", "mysqladmin", "-uroot", "-p${MYSQL_ROOT_PASSWORD}", "ping"]
      interval: 5s
      timeout: 5s
      retries: 5
    image: mysql:5.7.22
    restart: always
    volumes:
      - ./initdb:/docker-entrypoint-initdb.d

  guacamole:
    depends_on:
      guacd:
        condition: service_started
      mysql:
        condition: service_healthy
    environment:
      GUACD_HOSTNAME: guacd
      MYSQL_HOSTNAME: ${MYSQL_HOSTNAME}
      MYSQL_DATABASE: ${MYSQL_DATABASE}
      MYSQL_USER: ${MYSQL_USER}
      MYSQL_PASSWORD: ${MYSQL_PASSWORD}
      MYSQL_DRIVER: mysql
      MYSQL_SSL_MODE: disabled
    image: guacamole/guacamole
    ports:
      - 8080:8080
    links:
      - guacd
    restart: always

我改变的事情：

1. 使用早期的 MySQL 映像 (

   mysql:5.7.22

   )。
2. 为

   mysql

   服务指定显式运行状况检查，以确保 MySQL 在 Guacamole 启动之前就已做好连接准备。

我使用的是默认网络，但您可以集成您的特定网络。
