安装CRI O

dnf -y install 'dnf-command(copr)'

dnf -y copr enable rhcontainerbot/container-selinux

将在我们的系统中添加 CRI-O 1.24 存储库。将 CRI-O 的版本号导出为变量。

export KUBE_VERSION=1.24

curl -L -o /etc/yum.repos.d/devel:kubic:libcontainers:stable.repo https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/CentOS_8/devel:kubic:libcontainers:stable.repo

curl -L -o /etc/yum.repos.d/devel:kubic:libcontainers:stable:cri-o:${KUBE_VERSION}.repo https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable:cri-o:${KUBE_VERSION}/CentOS_8/devel:kubic:libcontainers:stable:cri-o:${KUBE_VERSION}.repo

列出系统上可用的存储库：

dnf -y repolist

配置存储库后，在 Rocky Linux 8 上安装 CRI-O 容器运行时：

dnf install -y cri-o cri-tools

启动 crio 服务

systemctl enable --now crio

检查服务状态

systemctl status crio

CRI-O sock 文件的路径是：

ls /var/run/crio/crio.sock

拉取镜像

crictl pull alpine:latest

查看镜像列表

crictl images

要设置容器注册表并设置优先级，请编辑文件：

vim /etc/containers/registries.conf

示例配置

unqualified-search-registries = ["registry.fedoraproject.org", "registry.access.redhat.com", "registry.centos.org", "docker.io"]
