Originally created by @jabbasj on GitHub (Jun 19, 2024).

It seems like ENV Variables HTTP_PROXY, HTTPS_PROXY, http_proxy, https_proxy are not respected here... so I am not able to build my own docker image behind a proxy

@jabbasj are you using --build-args HTTP_PROXY="proxy.yourdoman.tld" in your docker build command to specify your proxy? It looks like --env is only used at runtime

I had my daemon configured to use the proxy based on this guide: https://docs.docker.com/config/daemon/proxy/

sudo systemctl show --property=Environment docker

Environment=HTTP_PROXY=proxy.yourdoman.tld HTTPS_PROXY=proxy.yourdoman.tld http_proxy=proxy.yourdoman.tld https_proxy=proxy.yourdoman.tld no_proxy=localhost,127.0.0.1,localaddress,localdomain.com NO_PROXY=localhost,127.0.0.1,localaddress,localdomain.com

But based on your feedback, I tried passing --build-arg HTTP_PROXY="proxy.yourdoman.tld" --build-arg HTTPS_PROXY="proxy.yourdoman.tld" --build-arg http_proxy="proxy.yourdoman.tld" --build-arg https_proxy="proxy.yourdoman.tld" explicitly

and also tried modifying ~/.docker/config.json

No luck :(

Also have this issue, my walk around is to make a base build image with pyodide + micropip downloaded, and then use the base image to build final image behind proxy.

Ya that's fair, you can also just copy the pre-downloaded files directly into the static directory as a work-around but I chose to simply disable this feature entirely since executing python generated by the LLM in the browser isn't very useful for my use-case (this doesn't affect the ability to use Tools)

Maybe you can try something like: https://github.com/gajus/global-agent?](https://github.com/pyodide/pyodide/issues/4891#issuecomment-2198004864)

global-agent works for me，modify package.json
"pyodide:fetch": "npm i global-agent --save-dev && GLOBAL_AGENT_HTTPS_PROXY=$HTTPS_PROXY GLOBAL_AGENT_HTTP_PROXY=$HTTP_PROXY node -r global-agent/bootstrap scripts/prepare-pyodide.js"

@bright-ren Could you share your Dockerfile? This would help me better resolve the issue.
