基于mcr.microsoft.com/dotnet/sdk:7.0将dotnet-ef安装到docker容器

Question

我有一个容器运行图像

mcr.microsoft.com/dotnet/sdk:7.0

。 我想用实体框架生成一个数据库迁移脚本。所以最后我想运行这个命令。

dotnet ef migrations add Initial --project Source\Path\To\My.csproj

这就是我所做的：

• 运行容器

  docker run -dti --name ProjectName.Build.Container -v "ProjectSourceDir:/code" mcr.microsoft.com/dotnet/sdk:7.0

• 安装

  dotnet-ef

  工具

  docker exec -it ProjectName.Build.Container dotnet tool install --global dotnet-ef

  输出为：

Tools directory '/root/.dotnet/tools' is not currently on the PATH environment variable.
If you are using bash, you can add it to your profile by running the following command:

cat << \EOF >> ~/.bash_profile
# Add .NET Core SDK tools
export PATH="$PATH:/root/.dotnet/tools"
EOF

You can add it to the current session by running the following command:

export PATH="$PATH:/root/.dotnet/tools"

You can invoke the tool using the following command: dotnet-ef
Tool 'dotnet-ef' (version '7.0.5') was successfully installed.

• 迁移

  docker exec -it Projectname.Build.Container dotnet ef migrations add Initial --project /code/Source/Path/To/My.csproj

  但是我得到以下错误

Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET program, but dotnet-ef does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

但是我无法将

/root/.dotnet/tools

添加到我的

Path

中，因为

/root

目录是空的。而

/home

目录也是空的。 我能做些什么来解决这个问题？

当我

sh

进入容器时，这是

dotnet tool list -g

的输出

# dotnet tool list -g
Package Id      Version      Commands
--------------------------------------
dotnet-ef       7.0.5        dotnet-ef

这是

dotnet --info

的输出

顺便说一句。我在 Synology NAS 上运行 docker。
