Delve not installing in docker container-CodePudding

I'm trying to get delve installed in my docker container for debugging Go applications.

In my Dockerfile I put:

RUN go get github.com/go-delve/delve/cmd/dlv

But when I enter the docker container and run dlv it says

bash: dlv: command not found

I tried manually installing it by running go get github.com/go-delve/delve/cmd/dlv directly in the container. It finishes with no output. But I still get the same "command not found" error

It doesn't look like it installed delve at all. Here are my environment variables and Go bin directories inside the container:

I'm stumped as to why it's not installing... Any idea?
