Docker的错误和解决

错误一

docker build" requires exactly 1 argument.

See 'docker build --help'.

Usage:  docker build [OPTIONS] PATH | URL | -

Build an image from a Dockerfile

解决  docker build -t order .   (结尾有一个点)

错误二

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post "http://%2Fvar%2Frun%2Fdocker.sock/v1.40/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&session=2dsejav1qs1af91h7cpcg76g0&shmsize=0&t=order&target=&ulimits=null&version=1": dial unix /var/run/docker.sock: connect: permission denied

解决方法  找不到文件

sudo groupadd docker #添加docker用户组

sudo gpasswd -a $XXX docker #检测当前用户是否已经在docker用户组中，其中XXX为用户名。

sudo gpasswd -a $USER docker #将当前用户添加至docker用户组

newgrp docker #更新docker用户组

错误三

解决方法 就是更改DockerFile 里的地址

到这个地址里面找

microsoft-dotnet-sdk - Official Image | Docker Hub

ROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base

#mcr.microsoft.com/dotnet/aspnet:8.0

WORKDIR /app

EXPOSE 80

#-buster

FROM mcr.microsoft.com/dotnet/core/sdk:8.0 AS build

错误四

COPY failed: stat /var/lib/docker/tmp/docker-builder239868573/Order.API/Order.API.csproj: no such file or directory

解决方法

sudo chmod -R 777 /var/lib/docker/

问题五

Step 6/16 : COPY ["Order.API/Order.API.csproj", "Order.API/"]

COPY failed: stat /var/lib/docker/tmp/docker-builder470893402/Order.API/Order.API.csproj: no such file or directory

解决方法

1   COPY ["./*.csproj", "./"]  //注意路径就行

2   COPY ["./Order.API.csproj", "Order.API/"]  

问题六

在 docker 中使用这些文件，运行报错，检查文件才行

问题七

Docker 启动后 不能访问

解决访问

映射到80 不能行，更改后ok

使用  vi /etc/sysctl.conf

# 解除 net.ipv4.ip_forward = 1 的注释

然后重启服务，命令：

systemclt restart NetworkManager.service

systemctl restart docker.service

问题八

ERROR: failed to solve: mcr.microsoft.com/dotnet/sdk:8.0: failed to do request: Head "https://mcr.microsoft.com/v2/dotnet/sdk/manifests/8.0": dial tcp: lookup mcr.microsoft.com on 127.0.0.53:53: server misbehaving

此处更换其他dockerfile解决
