docker可视化工具(docker UI 和shipyard)

一、docker UI

1.1 介绍

DockerUI是一个开源的基于Docker API的web应用程序，提供等同Docker命令行的大部分功能，支持container管理，image管理。它最值得称道的是它华丽的设计和用来运行和管理docker的简洁的操作界面。

DockerUI优点：

     1）支持container批量操作；

     2）支持image管理（虽然比较薄弱）

DockerUI缺点：

     1）不支持多主机。

     2）不支持鉴权

1.2 部署

1.2.1 拉镜像

#拉镜像
docker pull uifd/ui-for-docker
#检查
[root@docker]-[~]-#docker images|grep ui
uifd/ui-for-docker                 latest                         965940f98fa5   5 years ago     8.1MB

1.2.2 启动容器

#容器启动
docker run -it -d --name docker-web -p 9090:9000 -v /var/run/docker.sock:/var/run/docker.sock docker.io/uifd/ui-for-docker
#检查
[root@docker]-[~]-#docker ps |grep web
164aaf6b30af   uifd/ui-for-docker                         "/ui-for-docker"         About an hour ago   Up About an hour   0.0.0.0:9090->9000/tcp, :::9090->9000/tcp                                              docker-web

1.2.3 访问页面

http://10.10.201.224:9090

1.3 使用

1.3.1 Dashboard

显示所有容器运行情况、容器创建周期、镜像拉取周期。

1.3.2 Containers

查看容器运行状态、日志情况等

 1.3.3 Containers Network

1.3.4 Images

 1.3.5 Networks

1.3.6 Volumes

1.3.7 Docker Information

　　3.优点

       # 支持容器管理

　　# 支持镜像管理

　　# 基于docker api，自身也是一个容器。

　　# 稳定性高

　　# 可动态显示显示容器之间关系图

　　# 容器管理，增加端口映射，增加系统变量、映射目录等

4.缺点

　　# 没有登录验证，因为没有登录体系，目前解决办法是，只开放本地访问，或者通过TLS来对权限进行控制。

　　# 无法分配某容器给某用户。

　　# 不支持多主机。

　　# 不支持集群swarm等

　　# 功能少

　　# 不支持控制台命令

二、shipyard

2.1 介绍

       shipyard是docker的web可视化界面管理工具，是建立在docker集群管理工具Citadel之上，可以管理镜像、容器、主机等资源的web图形化工具，包括core和extension两个版本，core即shipyard主要是把多个 Docker host上的 containers 统一管理（支持跨越多个host），extension即shipyard-extensions添加了应用路由和负载均衡、集中化日志、部署等。Shipyard是在Docker Swarm实现对容器、镜像、docker集群、仓库、节点进行管理的web系统。

       通过Web用户界面，你可以浏览相关信息，比如你的容器在使用多少处理器和内存资源、在运行哪些容器，哪些镜像，还可以检查所有集群上的事件日志等。

其特性主要包括：

1）支持节点动态集群，可扩展节点的规模（swarm、etcd方案）

2）支持镜像管理、容器管理、节点管理等功能

3）可视化的容器管理和监控管理

4）在线连接容器console终端

3.2 部署

官网：deploy – shipyard project

2.2.1 拉取镜像

通过脚本快速拉取镜像，启动容器：

1.建立脚本文件
vim  deploy

脚本如下

#!/bin/bash
 
if [ "$1" != "" ] && [ "$1" = "-h" ]; then
    echo "Shipyard Deploy uses the following environment variables:"
    echo "  ACTION: this is the action to use (deploy, upgrade, node, remove)"
    echo "  DISCOVERY: discovery system used by Swarm (only if using 'node' action)"
    echo "  IMAGE: this overrides the default Shipyard image"
    echo "  PREFIX: prefix for container names"
    echo "  SHIPYARD_ARGS: these are passed to the Shipyard controller container as controller args"
    echo "  TLS_CERT_PATH: path to certs to enable TLS for Shipyard"
    echo "  PORT: specify the listen port for the controller (default: 8080)"
    echo "  IP: specify the address at which the controller or node will be available (default: eth0 ip)"
    echo "  PROXY_PORT: port to run docker proxy (default: 2375)"
    exit 1
fi
 
if [ -z "`which docker`" ]; then
    echo "You must have the Docker CLI installed on your \$PATH"

2.给脚本执行权限
chmod 777 deploy
3.执行此脚本
./deploy

2.2.2 页面访问

访问地址：http://10.10.201.224:8080

登录用户名/密码：admin/shipyard

3.优点

　　# 支持镜像管理、容器管理。

　　# 支持控制台命令

　　# 容器资源消耗监控

　　# 支持集群swarm，可以随意增加节点

　　# 支持控制用户管理权限，可以设置某个容器对某个用户只读、管理权限。

　　# 有汉化版

4.缺点

　　# 启动容器较多，占用每个节点的一部分资源

　　# 兼容性性不高，可能是我自身原因，经常打不开首页。
