Learning Prometheus (Prometheus Stack) Through Hands-on Practice
This course is practice-oriented to help you understand Prometheus (🔥) as easily and quickly as possible. 🧭 In particular, it expands upon the proven content from the bestseller 'Kubernetes/Docker for Building Container Infrastructure Environments' to allow for a deeper study of Prometheus itself. 💯 Additionally, practical content is periodically added through 'supplementary lessons.' I am confident that no other lecture covers Prometheus as deeply and broadly as this one!

Changed repo due to CentOS support ending (mirror to valut)
hello
CentOS, which has been supported for a long time, has reached EOL (End of Life) on June 30, 2024.
Accordingly, the mirror site can no longer receive content related to the package, and it has been moved to the vault domain.
The reason I am sending you the entire email is to organize the following:
Ensemble uses box images that I don't maintain directly, so it looks like it will be updated to its own images soon.
Kubernetes considers the image deprecated when updating to v1.30, and CentOS no longer updates it. The main image is moving to Ubuntu 22.04.
But I think there are still people who need to use it.
Please be advised that if you change the domain with the following command, you will be able to use it for a certain period of time (which I cannot guarantee...).
sed -i 's,mirrorlist.centos.org,vault.centos.org,g' /etc/yum.repos.d/CentOS-Base.repo [root@m-k8s ~]# yum repolist Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.kakao.com * epel: mirror-nrt.yuki.net.uk * extras: mirror.kakao.com * updates: mirror.kakao.com kubernetes | 1.4 kB 00:00:00 repo id repo name status base/7/x86_64 CentOS-7 - Base 10,072 docker-ce-stable/7/x86_64 Docker CE Stable - x86_64 337 epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64 13,791 extras/7/x86_64 CentOS-7 - Extras 526 kubernetes Kubernetes 1,022 updates/7/x86_64 CentOS-7 - Updates 6,173 repolist: 31,921Additionally, being moved to the vault means that security updates, etc. for that OS will no longer be provided, so it will be gradually phased out from corporate environments.
I think it would be good if you could proceed with sufficient understanding of this point.
thank you
