1 containerd 部署

1.1 Containerd安装及配置

获取软件包

wget https://github.com/containerd/containerd/releases/download/v1.7.9/cri-containerd-cni-1.7.9-linux-amd64.tar.gz

1.2 安装containerd

tar -xf cri-containerd-cni-1.7.9-linux-amd64.tar.gz -C /

默认解压后会有如下目录：
etc
opt
usr
会把对应的目解压到/下对应目录中，这样就省去复制文件步骤。

1.3 生成配置文件并修改

mkdir /etc/containerd

containerd config default >/etc/containerd/config.toml

# ls /etc/containerd/
config.toml

下面的配置文件中已修改，可不执行，仅修改默认时执行。
sed -i 's@systemd_cgroup = false@systemd_cgroup = true@' /etc/containerd/config.toml

下面的配置文件中已修改，可不执行，仅修改默认时执行。
sed -i '[email protected]/pause:[email protected]/google_containers/pause:3.9@' /etc/containerd/config.toml

2 下载libseccomp-2.5.1版本的软件包

wget http://rpmfind.net/linux/centos/8-stream/BaseOS/x86_64/os/Packages/libseccomp-2.5.1-1.el8.x86_64.rpm

2.1 安装libseccomp-2.5.1软件包

#卸载原来的
 rpm -qa | grep libseccomp
libseccomp-devel-2.3.1-4.el7.x86_64
libseccomp-2.3.1-4.el7.x86_64

rpm -e libseccomp-devel-2.3.1-4.el7.x86_64 --nodeps
rpm -e libseccomp-2.3.1-4.el7.x86_64 --nodeps

rpm -ivh libseccomp-2.5.1-1.el8.x86_64.rpm 

2.2 检查安装的版本，安装成功啦

rpm -qa | grep libseccomp

2.3 安装runc

由于上述软件包中包含的runc对系统依赖过多，所以建议单独下载安装。

默认runc执行时提示：runc: symbol lookup error: runc: undefined symbol: seccomp_notify_respond

wget https://github.com/opencontainers/runc/releases/download/v1.1.10/runc.amd64

chmod +x runc.amd64

替换掉原软件包中的runc

mv runc.amd64 /usr/local/sbin/runc

# runc -v
VERSION:
   1.1.10
commit: v1.1.10-0-g18a0cb0f
spec: 1.0.2-dev
go: go1.20.10
libseccomp: 2.5.1

systemctl enable --now containerd
systemctl status containerd
