# Docker ee安装 #

## 步骤 ##

*  安装docker ee
 *  安装UCP([Universal Control Plane ][Universal Control Plane])桌面端控制面板
 *  安装DTR([Docker Trusted Registry][])镜像仓库管理工具

## 安装docker ee ##

卸载以前就的docker版本

sudo yum remove docker \
                      docker-client \
                      docker-client-latest \
                      docker-common \
                      docker-latest \
                      docker-latest-logrotate \
                      docker-logrotate \
                      docker-selinux \
                      docker-engine-selinux \
                      docker-engine

删除现有的Docker EE存储库

sudo rm /etc/yum.repos.d/docker*.repo

设置下载Docker EE 地址

注意：该地址在申请的Docker ee的界面中

export DOCKERURL="<DOCKER-EE-URL>"

将值放入到yum变量中

sudo -E sh -c 'echo "$DOCKERURL/centos" > /etc/yum/vars/dockerurl'

安装Docker所需要的依赖

sudo yum install -y yum-utils \
      device-mapper-persistent-data \
      lvm2

添加Docker ee的yum源

sudo -E yum-config-manager \
        --add-repo \
        "$DOCKERURL/centos/docker-ee.repo"

通过yum源码安装Docker ee

sudo yum -y install docker-ee docker-ee-cli containerd.io

设置Docker ee开机启动

systemctl enable docker

启动Docker ee

systemctl start docker

验证Docker ee是否安装成功

[root@docker-ee-manager bin]# docker version
    Client:
     Version:           18.09.6
     API version:       1.39
     Go version:        go1.10.8
     Git commit:        1578dcadd2
     Built:             Sat May  4 02:09:15 2019
     OS/Arch:           linux/amd64
     Experimental:      false
    
    Server: Docker Engine - Enterprise
     Engine:
      Version:          18.09.6
      API version:      1.39 (minimum version 1.12)
      Go version:       go1.10.8
      Git commit:       1578dca
      Built:            Sat May  4 02:03:09 2019
      OS/Arch:          linux/amd64
      Experimental:     false

安装Docker ee参考文档

[https://docs.docker.com/install/linux/docker-ee/centos/][https_docs.docker.com_install_linux_docker-ee_centos]

## 安装UCP桌面操作 ##

通过安装好的Docker ee下载UCP依赖的一些image

docker image pull docker/ucp:3.1.7

备注： 因为一些翻墙的原因，下载的依赖镜像会特别慢，此时我使用的是我自己的阿里云镜像容器来进行下载.

通过如下命令来进行安装

docker container run --rm -it --name ucp \
      -v /var/run/docker.sock:/var/run/docker.sock \
      docker/ucp:3.1.7 install \
      --host-address <node-ip-address> \
      --interactive

注意此时可能出现如下错误

FATA[0010] unable to pass CNI pod CIDR range check : cni pod cidr 192.168.0.0/16 overlaps with ip 192.168.0.200 of node

通过添加参数–pod-cidr防止端冲突

docker container run --rm -it --name ucp   -v /var/run/docker.sock:/var/run/docker.sock   docker/ucp:3.1.7 install   --host-address 192.168.0.200   --interactive --pod-cidr 172.168.2.0/16

参数的一些详细信息可以参考官方文档给的一些提示

[https://docs.docker.com/reference/ucp/3.1/cli/install/][https_docs.docker.com_reference_ucp_3.1_cli_install]
