AER: Error of this Agent is Reported First
Let me give you an example. [Here's one of the best questions I've ever asked on the internet.]https://github.com/kata-containers/runtime/issues/2795) I've seen many better questions asked, but this is the best I've been able to manage. I provided a decent description of the problem, a test-case that allowed other people to reproduce it as well (not relevant in your case), what I tried that didn't work, and the exact log messages and system information that indicated the problem. I then followed up with the people who were helping me and the problem was resolved.

Set *minimum* CPU allocation for a service
in parts of prod we use a combination of cgroups (mentioned in the thread already), taskset https://man7.org/linux/man-pages/man1/taskset.1.html, and in other cases (HPC workloads on large clusters) Kata Containers to isolate and optimize application resources: https://katacontainers.io/

It might use a hypervisor though, as the pendulum swings back

Is there a trick to know we're in a container?
If you want a tool based solution to this, tools like amicontained can tell you that in a container and some information about the sandbox.

Ask r/kubernetes: What are you working on this week?
I'm looking into SECCOMP profiles as well, but so far is seems a lot of pain for little gain. This series by Paulo Gomes is my starting point. part2 part3 testing-container.

Container capabilities
If you want to check the exact syscalls and caps in a container, getting a shell and using something like amicontained https://github.com/genuinetools/amicontained is a good option.

Hardening Docker and Kubernetes with seccomp
We made a few changes here. Namely, we changed seccompProfile section where we specify RuntimeDefault type and we also changed the image to amicontained which is a container introspection tool that will tell us which syscalls are blocked, as well as some other interesting security info.
What are some alternatives?
