kubernetes v1.20项目之docker ce安装

k8s也将慢慢的弃用docker，这个咱不要关心了，主要是现在还是有好多的企业用的是docker引擎，主要是这个，也就是说短时间内企业还是不会淘汰docker的吧，这个安装docker和平时我们安装docker是一样的，可以参照安装docker 19版本的方法给集群的每一个机器都安装上docker，非常的简单，这个就算是一个小测试吧

下载docker 19二进制包

#我的是在master01上面操作的，只要在一台服务器上面下载就行了，没必要全部下载，一台下载完之后通过scp到其他的机器上面，不是很酷，包括docker的配置文件也是这样的操作的哟
##下载二进制包
[root@k8s-master01 ~]# wget https://download.docker.com/linux/static/stable/x86_64/docker-19.03.9.tgz

#将二进制包scp到k8s-node01
[root@k8s-master01 ~]# scp docker-19.03.9.tgz k8s-node01:~
root@k8s-node01's password: 
docker-19.03.9.tgz   

#将二进制包scp到k8s-node02上面                                                                                          100%   58MB  33.3MB/s   00:01    
[root@k8s-master01 ~]# scp docker-19.03.9.tgz k8s-node02:~
root@k8s-node02's password: 
docker-19.03.9.tgz                                                                                             100%   58MB  91.5MB/s   00:00    

##解压二进制包
[root@k8s-master01 ~]# tar zxvf docker-19.03.9.tgz

##添加到/bin目录下面，主要是有了docker命令
[root@k8s-master01 ~]# mv docker/* /usr/bin

#docker的配置文件编写
[root@k8s-master01 ~]# cat > /usr/lib/systemd/system/docker.service << EOF

#将docker配置文件scp到node01上面
[root@k8s-master01 ~]# scp /usr/lib/systemd/system/docker.service k8s-node01:/usr/lib/systemd/system/docker.service

#在node01上面重复master操作
[root@k8s-node01 ~]# tar zxvf docker-19.03.9.tgz
docker/
docker/docker-init
docker/runc
docker/docker
docker/docker-proxy
docker/containerd
docker/ctr
docker/dockerd
docker/containerd-shim
[root@k8s-node01 ~]# mv docker/* /usr/bin

##在node02上面重复操作
[root@k8s-node02 ~]# tar zxvf docker-19.03.9.tgz

[root@k8s-node02 ~]# mv docker/* /usr/bin

配置docker的阿里加速器

#在master node01 node02上面创建docker目录
[root@k8s-master01 ~]# mkdir /etc/docker
[root@k8s-node01 ~]# mkdir /etc/docker
[root@k8s-node02 ~]# mkdir /etc/docker

#在master01上面配置docker的加速器配置文件
[root@k8s-master01 ~]# cat > /etc/docker/daemon.json << EOF
> {
>   "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
> }
> EOF
#复制到node01上面
[root@k8s-master01 ~]# scp /etc/docker/daemon.json k8s-node01:/etc/docker/daemon.json
root@k8s-node01's password: 
daemon.json                                                                                                    100%   67    82.0KB/s   00:00    

##复制到node02上面
[root@k8s-master01 ~]# scp /etc/docker/daemon.json k8s-node02:/etc/docker/daemon.json
root@k8s-node02's password: 
daemon.json       																								100%   67    82.0KB/s   00:00  

启动docker,并加入开机自启
