Docker compose文件版本兼容性错误

我有版本为20.10.5的docker引擎

Docker version 20.10.5, build 55c4c88

和docker compose版本1.23.2

docker-compose version 1.23.2, build 1110ad01

在ubuntu版本20.04上

Linux ed 5.4.0-66-generic #74-Ubuntu SMP Wed Jan 27 22:54:38 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

当我尝试在版本为3.8的文件上使用docker compose命令时，它会给出错误

ERROR: Version in "./jenkins.docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.

如果我改为3.7版，它就可以工作了。Docker文档提到3.8版应与Docker engine 19.03.0一起使用+

version: '3.8'
services:
  jenkins:
    build: .  
    image: jenkins:lts
    container_name: jenkins
    privileged: true
    restart: always
    ports:
      - "50000:50000"
      - "8080:8080"
    networks:
      - ed 
    volumes:
      - jenkins-log:/var/log/jenkins
      - jenkins-data:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock
      - ./downloads:/var/jenkins_home/downloads
      - /usr/bin/docker:/usr/bin/docker

我缺少什么？

您的

docker compose版本不支持compose 3.8版。您需要更新到至少
docker compose
1.25.5版：
谢谢。我无法在官方兼容性文档中看到。我认为这些信息应该成为网站文档的一部分
