Why doesn't htop show my docker-processes using wsl2
Building my container using docker and wsl2 I wanted to see what happens. Running htop in wsl only shows the CPU usage, but none processes running in my containers.
The only information searching for htop, docker and wsl2, the only thing I could find was this archived and unrelated reddit-thread: https://www.reddit.com/r/bashonubuntuonwindows/comments/dia2bw/htop_on_wsl2_doesnt_show_any_processes_while_ps/
Solution
Docker does not run in your default WSL-distro, but in a special Docker-Wsl-distro. Running wsl -l shows the installed distros:
Ubuntu (Standard)
docker-desktop
docker-desktop-data
Docker desktop is based on alpine and you can run top right out of the box:
wsl -d docker-desktop top
If you want htop, you need to install it first:
wsl -d docker-desktop apk update
wsl -d docker-desktop apk add htop
Running
wsl -d docker-desktop htop
will now give you a nice overview of what is happening in your docker-containers:
