安装:
------------------------------------------------------------------------------------------------------------------------------------------
在ECS上安装Docker,需要关注两个问题:
1.ECS的系统版本,内核版本
2.containerd.io及Docker版本
查询内核
我这里以 CentOS 8.0 64位,内核可以用 #uname -a查询
一般来说安装Docker需要内核高于3.8。
如果低于则需要更新内核,更新内核可在ECS官方文档和论坛找到方法,因为CentOS 8 一般不用升级
添加yum源
由于ECS的CentOS 的yum没有repo是对应Docker的源,所以这里需要添加源
vim /etc/yum.repos.d/docker.repo
这里给/etc/yum.repos.d/目录下添加repo,内容如下:
[docker-ce-stable] name=Docker CE Stable - $basearch baseurl=https://download.docker.com/linux/centos/7/$basearch/stable enabled=1 gpgcheck=0 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-stable-debuginfo] name=Docker CE Stable - Debuginfo $basearch baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/stable enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-stable-source] name=Docker CE Stable - Sources baseurl=https://download.docker.com/linux/centos/7/source/stable enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-edge] name=Docker CE Edge - $basearch baseurl=https://download.docker.com/linux/centos/7/$basearch/edge enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-edge-debuginfo] name=Docker CE Edge - Debuginfo $basearch baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/edge enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-edge-source] name=Docker CE Edge - Sources baseurl=https://download.docker.com/linux/centos/7/source/edge enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-test] name=Docker CE Test - $basearch baseurl=https://download.docker.com/linux/centos/7/$basearch/test enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-test-debuginfo] name=Docker CE Test - Debuginfo $basearch baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/test enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg [docker-ce-test-source] name=Docker CE Test - Sources baseurl=https://download.docker.com/linux/centos/7/source/test enabled=0 gpgcheck=1 gpgkey=https://download.docker.com/linux/centos/gpg
安装Docker
yum install docker-ce -y
但是安装这里可能会出现问题,这是因为你的containerd.io版本过低,不能直接安装最新版docker-ce
package docker-ce-3:19.03.2-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
- cannot install the best candidate for the job
两种解决方法:(1)直接安装低版本Docker,建议这个
(2)更新containerd.io
因为我查找containerd.io,发现其安装版本只有一个,可能ECS对应的源,我没有添加原来的源(懒得弄了)
干脆直接安装低版本Docker,查看yum下docker-ce版本
yum list docker-ce --showduplicates | sort -r
yum -y install docker-ce-18.06.0.ce-3.el7
这里直接选用18.06.0.ce-3.el7以下版本即可,安装成功
