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

1. 查看镜像引用

docker images

2. 删除镜像引用

docker rmi <镜像名称>:<标签>

3. 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

报错：

docker push crpi-5qc4odiityxeoecl.cn-hangzhou.personal.cr.aliyuncs.com/aliyun-namespace-lym/dpanel/dpanel:latest
The push refers to repository [crpi-5qc4odiityxeoecl.cn-hangzhou.personal.cr.aliyuncs.com/aliyun-namespace-lym/dpanel/dpanel]

denied: requested access to the resource is denied

解决方式

1. 登录到目标镜像仓库

docker login xxx.xxx.xxx.cr.aliyuncs.com

2. 重新配置镜像仓库
   如果问题仍然存在，可以尝试重新配置镜像仓库
   2.1. 删除镜像仓库。
   2.2. 重新创建镜像仓库。
   2.3. 重新推送镜像

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: bridge
  another_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
