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?
Idk how to decide what is safe or not, but as a warning, Docker containers can escape trivially and have access to the kernel.
Can you expand on this wild claim? The whole point of containers is isolation so what you are saying is that containers fail at that all the time?
They might be talking about posts like this (which I would love to have refuted, as this kind of info has so far kept me from using Docker significantly):

There is nothing to refute, 100% correct
This is not true. Perhaps on an already at-risk or exploitable machine, but even then it’s not trivial, and this is not a widespread thing that happens everywhere all the time
It is. Privilege escalation vulnerabilities are common. There is basically a 100% chance of unpatched container escapes in the Linux kernel. Some of these are very likely privately known and available for sale. So even if you are fully patched a resourceful attacker will escape the container.
That being said if you are a low-value regular-joe patching regularly, the risk is relatively low.
