CRI-O 安装使用

准备在 CentOS 8 中使用 CRI-O

在 Github 中下载 CRI-O 的二进制压缩包:https://storage.googleapis.com/k8s-conform-cri-o/artifacts/crio-v1.19.0.tar.gz

下载完成后进行解压。

安装

在下载的二进制压缩包中有一个 README.md,可以按照其中的步骤进行安装。

安装:

$ sudo yum install make -y
$ sudo make install

过程如下:

install  -d -m 755 /etc/cni/net.d
install  -D -m 755 -t /opt/cni/bin cni-plugins/*
install  -D -m 644 -t /etc/cni/net.d contrib/10-crio-bridge.conf

上边都是一些关键的文件和配置目录。

启动:

$ sudo systemctl daemon-reload
$ sudo systemctl enable --now crio
$ sudo systemctl start --now crio

查看状态:

$ sudo systemctl status crio

如果要卸载,需要执行:

$ sudo make uninstall

测试:

$ sudo su -
$ export PATH=$PATH:/usr/local/bin
$ crictl ps
