PATH environment variable overwritten in version 4.0.1 using Docker image

OS/Web Information

• Web Browser: Firefox 95.0.1
• Local OS: Ubuntu 20.04
• Remote OS:
• Remote Architecture:
• code-server --version: 4.0.1

Steps to Reproduce

The problem can be reproduced by building the following minimal Docker image :

FROM codercom/code-server:4.0.1
ENV PATH="/home/coder/local/bin/conda/bin:${PATH}"
RUN echo $PATH

and running it as a local server in the browser as explained in the installation guide.

Expected

When opening a terminal in VSCode, the value of $PATH should be the same as the one echoed at the end of the docker build step. The behavior is correct when building the image from code-server:3.12.0.

Actual

When building from code-server:4.0.1, the $PATH variable gets overwritten with the following path /usr/lib/code-server/vendor/modules/code-oss-dev/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games. If I run an interactive shell in the docker image using docker exec, the $PATH is as expected. But when opening VSCode in the browser, it is incorrect. I don’t see any command in the entrypoint.sh script which modifies this variable.

Thank’s for this great software.

@rafipiccolo

our workaround for the time being :

ENV PATH=xxxx
RUN echo "export PATH=$PATH" >> /home/coder/.bashrc 

which sets the correct $PATH provided $SHELL is set to /bin/bash, which it is by default.

I took a short look but nothing stood out in particular. We will need to dig in a bit more.
