Ubuntu利用docker搭建Java相关环境问题记录
Docker拉取镜像超时
报错
Unable to find image 'dpanel/dpanel:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/ ": context deadline exceeded (Client.Timeout exceeded while awaiting headers)
解决方式
在etc/docker/目录下创建daemon.json文件，将下面内容粘贴进去。
{"registry-mirrors": ["https://registry.cn-hangzhou.aliyuncs.com","https://do.nark.eu.org","https://dc.j8.work","https://docker.m.daocloud.io","https://dockerproxy.com","https://docker.mirrors.ustc.edu.cn","https://docker.nju.edu.cn"]
}
docker重新加载文件，然后重启；
sudo systemctl daemon-reload
sudo systemctl restart docker
命令方式操作
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://registry.cn-hangzhou.aliyuncs.com","https://do.nark.eu.org","https://dc.j8.work","https://docker.m.daocloud.io","https://dockerproxy.com","https://docker.mirrors.ustc.edu.cn","https://docker.nju.edu.cn"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker镜像被多个仓库引用
报错
Error response from daemon: conflict: unable to delete c2a6a40506b9 (must be forced) - image is referenced in multiple repositories
解决方式
- 查看镜像引用
docker images
- 删除镜像引用
docker rmi <镜像名称>:<标签>
- 强制删除镜像
如果镜像仍然无法删除，可以使用 -f 或 --force 选项强制删除：
docker rmi -f <镜像名称/id>
Docker未正确登录到镜像仓库，或权限不足

docker-compose.yml文件配置错误
报错
compose up
yaml: unmarshal errors:line 109: mapping key "networks" already defined at line 107
解决
确保 networks 部分只定义一次。如果需要定义多个网络，应该将它们放在同一个 networks 部分下。例如：
networks:my_network:driver: bridgeanother_network:driver: bridge
未在 docker-compose.yml文件所在目录启动
报错
docker compose up
no configuration file provided: not found
解决
指定配置文件路径
docker compose -f /path/to/docker-compose.yml up
