本文记录了openEuler22.03LTS将docker升级由18.09.0升级至26.1.4的过程（当前docker最新版本为27.5.1，生产环境为保障稳定性，选择升级到上一个大版本26的最新小版本）。

一、现有环境

1、系统版本

[root@localhost opt]# cat /etc/os-release 
NAME="openEuler"
VERSION="22.03 LTS"
ID="openEuler"
VERSION_ID="22.03"
PRETTY_NAME="openEuler 22.03 LTS"
ANSI_COLOR="0;31"

 2、docker版本

[root@localhost opt]# docker --version
Docker version 18.09.0, build 4ca0e26

二、升级准备

1、卸载现有版本

[root@localhost opt]# yum  remove docker -y      
Dependencies resolved.

 2、从docker官网下载目标软件包

下载链接：

docker-26.1.4官网下载

下载实作

[root@localhost opt]# wget https://download.docker.com/linux/static/stable/x86_64/docker-26.1.4.tgz

[root@localhost opt]# ll
..
-rw-r--r--. 1 root root  71M  6月 18  2024 docker-26.1.4.tgz

三、升级软件

1、解压软件包

[root@localhost opt]# tar -xzvf docker-26.1.4.tgz 
docker/
docker/docker-init
docker/docker-proxy
docker/docker
docker/containerd-shim-runc-v2
docker/runc
docker/ctr
docker/dockerd
docker/containerd
[root@localhost opt]# ll docker

-rwxr-xr-x. 1 AAAA AAAA  38M  6月  5  2024 containerd
-rwxr-xr-x. 1 AAAA AAAA  12M  6月  5  2024 containerd-shim-runc-v2
-rwxr-xr-x. 1 AAAA AAAA  19M  6月  5  2024 ctr
-rwxr-xr-x. 1 AAAA AAAA  37M  6月  5  2024 docker
-rwxr-xr-x. 1 AAAA AAAA  68M  6月  5  2024 dockerd
-rwxr-xr-x. 1 AAAA AAAA 692K  6月  5  2024 docker-init
-rwxr-xr-x. 1 AAAA AAAA 1.9M  6月  5  2024 docker-proxy
-rwxr-xr-x. 1 AAAA AAAA  15M  6月  5  2024 runc

2、复制文件到/usr/bin目录 

[root@localhost opt]# cp docker/* /usr/bin

3、编写service文件 

[root@localhost opt]# vi docker.service
...
[root@localhost opt]# cat docker.service 
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target[Service]
Environment="HTTP_PROXY=http://192.168.80.1:50691"
Environment="HTTPS_PROXY=http://192.168.80.1:50691"
Type=notify
EnvironmentFile=-/etc/sysconfig/docker
EnvironmentFile=-/etc/sysconfig/docker-storage
EnvironmentFile=-/etc/sysconfig/docker-network
Environment=GOTRACEBACK=crashExecStart=/usr/bin/dockerd $OPTIONS \$DOCKER_STORAGE_OPTIONS \$DOCKER_NETWORK_OPTIONS \$INSECURE_REGISTRY
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=1048576
LimitNPROC=1048576
LimitCORE=infinity
# 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=processRestart=on-failure 
StartLimitBurst=3 
StartLimitInterval=60s [Install]
WantedBy=multi-user.target

4、将service文件复制到相应文件夹 

[root@localhost opt]# chmod 644 docker.service
[root@localhost opt]# cp docker.service /usr/lib/systemd/system/docker.service

 5、启动服务

[root@localhost opt]# systemctl daemon-reload
[root@localhost opt]# systemctl start docker
[root@localhost opt]# systemctl enable docker
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

6、验证版本 

[root@localhost opt]# docker --version
Docker version 26.1.4, build 5650f9b
[root@localhost opt]# docker version
Client:Version:           26.1.4API version:       1.45Go version:        go1.21.11Git commit:        5650f9bBuilt:             Wed Jun  5 11:27:57 2024OS/Arch:           linux/amd64Context:           defaultServer: Docker Engine - CommunityEngine:Version:          26.1.4API version:      1.45 (minimum version 1.24)Go version:       go1.21.11Git commit:       de5c9cfBuilt:            Wed Jun  5 11:29:25 2024OS/Arch:          linux/amd64Experimental:     falsecontainerd:Version:          v1.7.18GitCommit:        ae71819c4f5e67bb4d5ae76a6b735f29cc25774erunc:Version:          1.1.12GitCommit:        v1.1.12-0-g51d5e94docker-init:Version:          0.19.0GitCommit:        de40ad0

 升级成功。

 四、验证启用ip6tables功能

本次升级旨在解决openEuler22.03LTS原生docker不支持ip6tables的问题，，(docker engine 的版本从20.10.2及以上才开始支持ip6tables，这里ip6tables是指由docker自动配置 IPv6 的防火墙规则。)

低版本docker引擎配置启用ip6tables，会出现以下报错日志无法启动

....systemd[1]: Starting Docker Application Container Engine...
...dockerd[5597]: unable to configure the Docker daemon with file /etc/docker/daemon.jso>
...systemd[1]: docker.service: Main process exited, code=exited, status=1/FAILURE
...systemd[1]: docker.service: Failed with result 'exit-code'.
...: Failed to start Docker Application Container Engine.
...: Starting Docker Application Container Engine...

 测试配置启用ip6tables并重启服务

[root@localhost opt]# vi /etc/docker/daemon.json
[root@localhost opt]# cat /etc/docker/daemon.json
{"ipv6": true,"fixed-cidr-v6": "2001:db8:1::/64","experimental":true,"ip6tables": true
}
[root@localhost opt]# systemctl restart docker

正常通过。
