How do i you decide whats safe to run

I recently ran Gossa on my home server using Docker, mounting it to a folder. Since I used rootless Docker, I was curious - if Gossa were to be a virus, would I have been infected? Have any of you had experience with Gossa?

That is not how security works. You must protect against known and unknown attack vectors. I am only pointing out weaknesses of Docker and other linux containers that share the kernel with the host or/and run with Root. I'm not saying anything original or crazy, just read up on the security of these technologies and their limits. I am not a malware designer, I am a security researcher.

Look into gVisor and Kata Containers for info on how to improve the security of containers.

Here are some readings for you:
