Create a docker instance:

sudo docker run -it rockylinux:9 bash

In docker, run:

sed -e 's|^mirrorlist=|#mirrorlist=|g'     -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g'     -i.bak     /etc/yum.repos.d/rocky-extras.repo     /etc/yum.repos.d/rocky.repo
yum makecache

useradd -m mock

Then in host machine, do :

[root@dellnew ~]# docker ps

Next time using this latest commited kernel you could directly build kernel src.

Build via following command:

[root@text ~]# docker run --name=testrocky -v /root/buildout:/buildout -it buidrockykernel:latest /bin/bash

Try Steps

Replace the repository for speedup:

sed -e 's|^mirrorlist=|#mirrorlist=|g'     -e 's|^#baseurl=http://dl.rockylinux.org/$contentdir|baseurl=https://mirrors.ustc.edu.cn/rocky|g'     -i.bak     /etc/yum.repos.d/rocky-extras.repo     /etc/yum.repos.d/rocky.repo
yum makecache

Install docker:

dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
# replace all of the `download.docker.com` into `https://mirrors.ustc.edu.cn/docker-ce`
yum makecache
yum install -y docker-ce
systemctl enable docker
systemctl start docker

Pull rockylinux9 and prepare building environment via:

docker pull rockylinux:9

Enable perftools building, I think it failed because of the libebpf is too new comparing to 5.15.113 kernel. so changes to kerner’s tools/lib/bpf version’s libebpf-devel package for building.

cd iventory
tar xzvf ../iventoy-1.0.17-linux-free.tar.gz
cd iventoy-1.0.17
sudo ./iventoy.sh start

Select the DHCP server mode for external:
