使用vs连接远程进行调试会自动下载vsdbg到容器，但是由于网路问题，经常失败或者需要等很久，所以想把vsdbg环境提前安装到容器内，参考网上文章后调通了，步骤如下：
安装putty
vscode远程连接使用ssh时，无法在命令行参数中输入密码，比较麻烦，故使用putty，需要下载putty并安装
- 验证：cmd输入`plink
构建镜像
FROM mcr.microsoft.com/dotnet/aspnet:6.0 AS base
WORKDIR /app
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /src
COPY . .
RUN dotnet build -c Release -o /app/build
FROM build AS publish
RUN dotnet publish "./ConsoleApp1.csproj" -c Debug -o /app/publish
FROM base as final
WORKDIR /app
# 安装ssh server
RUN apt-get update && apt-get install -y --no-install-recommends openssh-server && mkdir -p /run/sshd
# 修改密码
RUN echo "root:123" | chpasswd
# 配置sshd
COPY sshd_config /etc/ssh/sshd_config
# 复制vsdbg程序
COPY vsdbg-linux /vsdbg
COPY --from=publish /app/publish .
EXPOSE 22
CMD /usr/sbin/sshd -D & dotnet ConsoleApp1.dll
对应sshd_config配置文件：
Port 22
ListenAddress 0.0.0.0
LoginGraceTime 180
X11Forwarding yes
Ciphers aes128-cbc,3des-cbc,aes256-cbc
MACs hmac-sha1,hmac-sha1-96
StrictModes yes
SyslogFacility DAEMON
PasswordAuthentication yes
PermitEmptyPasswords no
PermitRootLogin yes
vsdbg下载：vsdebugger.azureedge.net/vsdbg-16-3-…
添加远程主机putty连接信任
本机执行：plink -l root -pw 123 localhost -P 9922 -T并同意连接
vscode debug配置
configurations数组下添加：
{
"name": ".NET Core Remote Attach",
"type": "coreclr",
"request": "attach",
"processId": "${command:pickRemoteProcess}",
"pipeTransport": {
"pipeCwd": "${workspaceFolder}",
"pipeProgram": "plink",
"pipeArgs": [ "-l", "root", "-pw", "123", "localhost", "-P", "9922", "-T" ], // putty连接参数
"debuggerPath": "/vsdbg/vsdbg" // vsdbg在docker容器中的路径
},
"sourceFileMap": {
"/src": "${workspaceFolder}"
}
}
运行调试
调试愉快~
