Okteto部署Rasa聊天机器人遇Invalid compose name错误求助

问题 #

通过Docker+Okteto部署Rasa聊天机器人，此前运行正常，今日突然报错：

Invalid compose name: must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character

退出状态码1。已尝试将docker-compose.yaml重命名为docker-compose.yml、okteto-compose.yml，问题未解决。

相关配置文件如下：

docker-compose.yaml #

version: '3.4'
services:

  rasa-server:
    image: rasa-bot:latest
    working_dir: /app
    build: "./"
    restart: always
    volumes:
    - ./actions:/app/actions
    - ./data:/app/data
    command: bash -c "rm -rf .rasa/* && rasa train && rasa run --enable-api --cors \"*\" -p 5006"
    ports:
    - '5006:5006'
    networks:
    - all

  rasa-actions-server:
    image: rasa-bot:latest
    working_dir: /app
    build: "./"
    restart: always
    volumes:
    - ./actions:/app/actions
    command: bash -c "rasa run actions"
    ports:
    - '5055:5055'
    networks:
    - all

networks:
  all:
    driver: bridge
    driver_opts:
      com.docker.network.enable_ipv6: "true"

解决方案 #

报错原因是Okteto校验Docker Compose项目名称时，发现名称不符合规则：必须由小写字母、数字或连字符组成，且首尾必须是字母或数字。

解决方法二选一：

• 方法1：修改项目所在目录名
  Okteto默认会用当前目录名作为Compose项目名，如果你的目录名包含大写字母、下划线或其他特殊字符，改成符合规则的名称（比如rasa-bot-deployment）。

• 方法2：在docker-compose.yml中显式指定项目名
  在version字段下方添加name字段，指定符合规则的项目名，示例：

  version: '3.4'
  name: rasa-bot-deployment  # 新增这一行，名称符合小写字母+连字符规则
  services:
    # 原services内容保持不变
  

说明 #

之前运行正常可能是因为Okteto近期更新了对Compose项目名称的校验规则，现在严格执行命名规范导致报错。
