Remote-Containers: Installing VSCode server fails if non-root user exists in dockerfile

[nphmuller]

Repro:

• Run Remote-Containers: Open folder in container... command
• Select random folder
• Pick Node.js (latest LTS)
• Open dockerfile
• Add USER node at end of dockerfile
• Run Remote-Containers: Rebuild Container command.
• An error occurred setting up the container.

Error output from CLI:

@nphmuller does reloading the Window (Command Developer: Reload Window) recover from this situation?

[nphmuller]

Nope. The situation can only be resolved by removing the non-root user from the Dockerfile.

[egamma]

@nphmuller can you share your Dockerfile in this issue?

It's basically the Node.js (latest LTS) template, with the single line added that I described. But sure.

# I ADDED THIS:
USER node

Try adding ENV HOME /home/node after USER node. This is a limitation tracked as #22.
