Exposed public port cannot bind

[Glydric]

Bug description

When i configure gitpod.yml i set

- name: web
port: 80
visibility: public

and the port shows on exposed ports as open, but if i run python -m http.server 80 or every server on 80 it say cannot bind to 0.0.0.0/80, other ports are working

@Glydric22 could you try sudo python -m http.server 80

[Glydric]

I have already tryied,
sudo: python: command not found

@Glydric22 use:

sudo -E $(command -v python3) -m http.server 80

@Glydric22 use:

sudo -E $(command -v python3) -m http.server 80

Seems to work... but why?

Seems to work... but why?

It's basically how your shell works, sudo doesn't preserve the user-environment variables by default, -E flags makes it do. Moreover, $(command -v python3) is expanded to /home/gitpod/.pyenv/shims/python3 before it gets passed as an argument to sudo, so sudo can directly execute python3 without iterating over PATH env-var to avoid possible conflict as we're using -E flag.

To see what actually happens, try:

bash -xc 'sudo -E $(command -v python3) -m http.server 80'
