Well, hi everyone, the truth is that to take into account the security and control of resources when putting into production a container-based architecture, you have to read a lot, because by default a container is deployed with everything enabled by default. It can use all the memory, CPU, disk access, and if you are not careful you can even assume that the root user does all the tasks. Obviously we have to avoid all that.
There is a lot to read, be advised! Thank you Bret Fisher.
