docker containerd cri-o 接入kata-containers

kata-containers 环境需求

# 必须开启虚拟化，如果是kvm 下面虚拟机虚拟机化 请升级内核到4版本以上同时开启
# 首先检查 KVM host（宿主机/母机）上的kvm_intel模块是否打开了嵌套虚拟机功能（默认是开启的）：
[root@ceph-2-52 ~]# modinfo kvm_intel | grep nested
parm:           nested_early_check:bool
parm:           nested:bool
[root@ceph-2-52 ~]#  cat /sys/module/kvm_intel/parameters/nested
Y
# 如果上面的显示结果不是 Y 的话需要开启 nested：
[root@ceph-2-52 ~]# modprobe -r kvm-intel
[root@ceph-2-52 ~]#  modprobe kvm-intel nested=1
[root@ceph-2-52 ~]# cat /sys/module/kvm_intel/parameters/nested
Y
#然后创建虚拟机即可
#使用qemu打开一个虚拟机在启动命令上加上“-cpu host”或“-cpu qemu64,+vmx”
#默认情况下,系统并不支持nested

#查看当前系统是否支持nested
systool -m kvm_intel -v  | grep -i nested
nested              = "N"
#或者这样查看
cat /sys/module/kvm_intel/parameters/nested
N

#第一步升级内核,用4以上内核做测试,升级内核很简单,下载编译好的内核rpm包,这里是下载地址,安装,然后修改#grub.conf默认引导内核为新内核
yum -y update
yum -y install yum-plugin-fastestmirror
yum install -y epel-release
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
yum -y --enablerepo=elrepo-kernel install kernel-ml
grub2-set-default 0
grub2-mkconfig -o /boot/grub2/grub.cfg
# 如果启动后内核没加载nested 就执行第二步
vim  /boot/grub2/grub.cfg
linux16 /vmlinuz-5.6.12-1.el7.elrepo.x86_64 root=UUID=f870e0a7-5edc-45a4-942c-3224020ac5b7 ro crashkernel=auto nodmraid biosdevname=0 net.ifnames=0 rhgb quiet kvm-intel.nested=1
#第二步添加引导参数同样很简单,只需要在 kernel 那一行的末端加上 "kvm-intel.nested=1"
# 重启检查
[root@ceph-2-52 ~]# cat /sys/module/kvm_intel/parameters/nested

# 修改以前有的kvm 虚拟机 xml

docker 集成kata-containers

# Create docker configuration folder
 mkdir -p /etc/docker

# dd the following definitions to /etc/docker/daemon.json
{
  "default-runtime": "kata-runtime",
  "runtimes": {
    "kata-runtime": {
      "path": "/usr/bin/kata-runtime"
    }
  }
}
# Restart the Docker systemd service with the following commands
 sudo systemctl daemon-reload
 sudo systemctl restart docker
 # Run Kata Containers
 docker run busybox uname -a
# 默认 1核 2G 配置
# 删除默认"default-runtime": "kata-runtime",
 docker run --runtime=kata-runtime -ti busybox /bin/sh
 #知道内存 cpu 大小
 docker run -tid --cpus 4 --memory 4096Mb  -ti busybox /bin/sh
# 遗憾的事就与K8S docker 集成会失败，当然如果不使用宿主机网络是没任何问题的。
