Malware postgres latest version in docker-compose

[iflemix]

Hello, I reinstalled my VDS machine twice because there was a problem with the "rediserver" process running inside the Postgres container (see below).
The process is completely hogging all system resources.

I installed Docker from the official documentation on the official Docker website.
I have no idea what this process is or what to do with it.
I'll include all the useful information I've dug up below.
I'm not an advanced Docker user or a DevOps administrator.

I tracked the process by its PID via systemd
When you try to kill him, he rises in two new copies.

In addition to the rediserver process, there is some suspicious sh script running, but (can be seen in the screenshot from the systemctl command)
I'm not sure if it is related to the problem.

Please help if possible, I will be very grateful to the community

My docker-compose at the moment

The second server, also running the latest Postgres, has the same process, but in the form of
kdevtmpfsi

I've already read about it somewhere.

I am wondering if it is the same as #1307

I understand that the problem is partly on my end because I'm providing bad authorization data, which allows one to easily access the PostgreSQL port and download malware.

Yes, this is definitely a compromised instance - I recommend taking it offline ASAP, restoring from a pre-compromise backup, and locking it down suitably (not exposing the ports to the internet, strong credentials, etc).
