前言
- 一般人最好用的修复漏洞的方式就是更新版本
- 起因是使用的Docker版本被检测出来有一堆漏洞(例如:Docker 操作系统命令注入漏洞(CVE-2019-5736))
- 更新环境无法联网,只能通过下载二进制文件的形式进行安装
步骤
- 可先通过
which docker
查看Docker可执行文件的地址 - 然后查看自己docker的版本:
docker versino
- 停止并卸载原有Docker:
shell
systemctl stop docker # 停止Docker服务
yum remove docker docker-common docker-selinux docker-engine # 卸载Docker(适用于CentOS)
- 下载二进制文件:https://download.docker.com/linux/static/stable/x86_64/
- 注意选择一个和原本Docker兼容的版本,具体啥兼容我也不知道,反正不要一次性版本更新太多,我第一次从19升级到24,然后后面死活构建不了镜像,最后选择了个20的最新版本,才成功构建镜像
- 解压缩:
tar xf docker-xxxxx.tgz
- 复制文件:
cp docker/* /usr/bin/
- 后面这个地址指的是docker可执行文件的地址,默认是/usr/bin/目录下
- 若提示覆盖,则选择覆盖即可
- 设置开机自启:
vi /etc/systemd/system/docker.service
,内容如下
shell
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target
- 给执行权限
shell
# 给执行权限
chmod +x /etc/systemd/system/docker.service
# 重新加载配置
systemctl daemon-reload
# 设置开机启动
systemctl enable docker.service
# 进行启动
systemctl start docker
- 如果此时有报错,看看containered组件是否启动
shell
# 查看containerd状态
systemctl status containerd
# 启动containerd服务
systemctl start containerd
- 最后如果所有容器启动成功,通过
Docker -version
查看版本
提醒
- 中间遇到了很多奇奇怪怪的Bug,就一点,先百度,百度解决不了就重启,注意不要随便用rm命令删除数据文件
- 比如Docker启动不了,直接重启虚拟机
- 如果容器启动不了,报啥端口占用啥的,直接重启Docker
