SUSE12 安装docker-ce19.03.13版本

发表于 分类于

官方不支持SUSE系统进行类似yum、apt-get方式安装docker-ce，可以按照以下方式进行安装。

前提

软件 版本
SUSE SUSE Linux Enterprise Server 12 SP2/SP5
Docker-ce 19.03.13

1、下载docker-ce软件压缩包

1
wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.13.tgz

2、解压到/usr/local/bin目录下

1
2
tar -zxvf docker-19.03.13.tgz
cp docker/* /usr/local/bin/.

3、编辑docker.service文件

新建/usr/lib/systemd/system/docker.service文件，添加如下参数

After=network-online.target containerd.service
Wants=network-online.target
Requires=docker.socket

[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

RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make

# in the kernel. We recommend using cgroups to do container-local accounting.

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.

# kill only the docker process, not all processes in the cgroup
KillMode=process

[Install]
WantedBy=multi-user.target

4、编辑docker.socket文件

新建/usr/lib/systemd/system/docker.socket文件，添加如下参数

5、编辑containerd.service文件

6、启动docker

systemctl start docker报错：

1
2
# systemctl start docker
A dependency job for docker.service failed. See 'journalctl -xe' for details.

解决：需要创建docker用户和组

1
2
3
useradd docker
groupadd docker
usermod -aG docker docker

再次启动docker

1
systemctl start docker && systemctl enable docker

7、测试创建容器

1
docker run -it --rm alpine sh

8、官方安装方式

突然找到，官方也有类似软件包安装方法。。。。
