Docker: Die Umgebungsvariable JENKINS_UC_DOWNLOAD scheint nicht zu funktionieren

Ich habe die Umgebungsvariable JENKINS_UC_DOWNLOAD mit docker-compose.yml konfiguriert, aber es scheint nicht zu funktionieren.

Docker-Befehle, die Sie ausführen

docker-compose up

und die docker-compose.yml-Datei ist unten:

version: "3.7"

services:
  jenkins:
    container_name: jenkins
    image: jenkins/jenkins:2.204.6
    restart: unless-stopped
    privileged: true
    ports:
      - "8080:8080"
      - "50000:50000"
    dns:
      - 223.5.5.5
      - 8.8.8.8
    environment:
      JENKINS_UC_DOWNLOAD: "https://mirrors.tuna.tsinghua.edu.cn/jenkins"   
      JAVA_OPTS: "-Djava.awt.headless=true -Duser.timezone=Asia/Shanghai -Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8"
    volumes:
      - ./jenkins_service/jenkins_certs:/certs/client
      - ./jenkins_service/jenkins_home:/var/jenkins_home
      - ./jenkins_service/jenkins_backup:/var/jenkins_backup
    deploy:
      resources:
        limits:
          memory: 2048M
          cpus: '2'
    networks:
      - jenkins_network

networks:
  jenkins_network:
    external: true

Tatsächliche Ergebnis

Das Jenkins-Download-Plugin nicht von der konfigurierten URL, sondern vom Jenkins Office Download Center.

Erwartetes Ergebnis

Das Jenkins sollte das Plugin von meiner konfigurierten URL herunterladen.

Haben Sie ein nicht angedocktes Jenkins ausprobiert und das erwartete Ergebnis erhalten?

Nein.
