I would like to get environment variables from windows container which is ran by docker command but I could not get expected value of the variables.
In Dockerfile, I placed one of instructions likes
ENV Hello=World
In command prompt of windows, it runs a command of
docker build -t myapp .
and the image build successfully. Then run the image
docker run -e "Hello=Bye" myapp
In C#, I tried to get the environment variable Hello by
string debug = Environment.GetEnvironmentVariable("Hello");
and the debug would get World.
If the instruction ENV Hello=World is not placed in Dockerfile, the debug would get null.
I don't know what I should do in C# that getting debug with the value Bye which is my expected result. Thanks for the help.
