The Linux Foundation Training Team
Most of the courses in these bootcamps were developed independently. LFS201 and LFS211 will work equally well on any major Enterprise distribution -- and the LFCS and LFCE exams can be given on either CentOS 7 at present, and Ubuntu 18.04 -- with CentOS 8 and Ubuntu 20.04 coming soon.
The CKA and CKAD exams do not require a specific platform and neither does LFD259 or LFS258, although you might get more out of it on a native Linux platform.
So technically you are not using an "approved" platform even by using RHEL 8 -- although I know for a fact that there should not be a problem and the courses have pretty much migrated to it even if the exams have not, while keeping RHEL 7 backward compatibility.
As Luis says, Docker is not gone from RHEL/CentOS 8. You should follow the instructions for using docker on it and you probably will not have a real problem, and as Luis says this is a course focused more generally on containers, not Docker. podman will work fine I hope although I cannot promise. I think you should plunge ahead and see what happens. If you have trouble you can always go set up an Ubuntu VM to work with in about 20 minutes, I've done it many times.
I would like to emphasize what Chris said: LFS253 is not all about Docker. For the Docker specifics -not available and supported by Red Hat 8 (that's a fact)- you can use Podman instead. There are important differences between these two implementations, but none or almost none from the perspective of the tool.
So, you can try and verify it by yourself. And I also want to share this article with you:
I hope that helps.
A Network Policy is equivalent to a firewall. It is not intended to change the type of a Service.
I would recommend revisiting a few sections of Chapter 7, specifically the "ClusterIP", "NodePort", and "LoadBalancer" to better understand these specific Service types, their similarities and differences. This will help you to find the expected solution to exercise 7.3.
Yes, that would be a more accurate representation of pod anti-affinity. I'll work on improving the language.
1/2 or one half of a pair, yes. We commonly use multiple VM's for testing however not everyone has a machine capable of running several VM's at once. Use of VM's is a suggestion.
@digitaltung LFS201 is the prep course for LFCS. Also, some LFCS topics are covered in LFS101. LFS211 is the prep course for LFCE.
