实验环境 - PWD本地搭建 - 《云原生-Docker》

背景说明

背景说明

PWD由于资源的限制有时候无法正确访问，可以自己本地部署供自己和相关人员使用。

解决方案

环境安装

环境准备

本机已经事先安装了Docker和epel源

运行环境

[root@vm1 ~]# yum install go
[root@vm1 ~]# go version
go version go1.16.13 linux/amd64
[root@vm1 ~]#

依赖镜像

[root@vm1 ~]# go env -w GO111MODULE=on
[root@vm1 ~]# go env -w GOPROXY=https://goproxy.cn,direct
[root@vm1 ~]# go env

[root@vm1 ~]#

源码下载

[root@vm1 ~]# git clone https://github.com/play-with-docker/play-with-docker
Cloning into 'play-with-docker'...

如果无法通过克隆进行下载，也可以通过浏览器进行下载zip文件然后解压并改名为play-with-docker即可

环境安装

进入目录play-with-docker

[root@vm1 ~]# cd play-with-docker/
[root@vm1 play-with-docker]# ls
api.go  docker              Dockerfile     dockerfiles  go.mod  handlers  id        k8s      prometheus.yml  pwd        router     storage
config  docker-compose.yml  Dockerfile.l2  event        go.sum  haproxy   internal  LICENSE  provisioner     README.md  scheduler  vendor
[root@vm1 play-with-docker]#

加载内核模块

[root@vm1 play-with-docker]# modprobe xt_ipvs
[root@vm1 play-with-docker]#

初始化swarm

[root@vm1 play-with-docker]# docker swarm init

下载镜像

[root@vm1 play-with-docker]# docker pull franela/dind

安装依赖

[root@vm1 play-with-docker]# go mod vendor

安装docker compose

[root@vm1 ~]# yum install docker-compose
[root@vm1 ~]# docker-compose --version
docker-compose version 1.18.0, build 8dd22a9
[root@vm1 ~]#

服务运行

[root@vm1 play-with-docker]# docker-compose up

后台运行 docker-compose up -d

访问验证

如果当前机器安装了图形化界面直接通过浏览器访问http://localhost即可正常访问，如果没有图形化界面，则可以使用wget命令进行验证

[root@vm1 play-with-docker]# cd ../
[root@vm1 ~]# wget http://localhost
--2022-04-10 18:38:23--  http://localhost/
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:80... failed: Connection refused.
Connecting to localhost (localhost)|127.0.0.1|:80... failed: Connection refused.
[root@vm1 ~]# ls
anaconda-ks.cfg index.html  play-with-docker
[root@vm1 ~]# cat index.html 

<!DOCTYPE html>
<html lang="en" ng-app="PWDLanding" ng-controller="LoginController">
  <head>
    <script src="https://unpkg.com/angular@1.6.6/angular.min.js"></script>
    <script src="https://unpkg.com/angular-cookies@1.6.6/angular-cookies.min.js"></script>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="">

此时不能通过机器的IP地址进行访问，只能通过localhost进行访问

高级配置

实例模板

由于云主机的性能资源有限，所以每次启动PWD，只提供了四个小时的在线实验时间，所以，当你的实验完成或者因为各种原因终止实验的时候，应当关闭当前终端，即点击左上角的橙色按钮“CLOSE SEESION”。此外，PWD还提供了预定义模板功能，可以用鼠标单击左侧的扳手icon，请注意，如果需要使用预定义模板功能，需要关闭当前 seesion 才可以正确启动。
模板功能提供了三个快速启动集群的选项：

3 Managers and 2 Workers
5 Managers and no Workers
1 Manager and 1 Workers

主机配置

修改监听地址和域名，如果部署在VPS上需要把localhost修改为域名或IP，编辑文件api.go,在api.go文件的 config.ParseFlags()下面添加config.PlaygroundDomain = “YOU-IP or DOMAIN

config.PlaygroundDomain = "192.168.184.130"

如下图所示

启动服务

[root@vm1 play-with-docker]# docker-compose up 
WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

Starting l2 ... 
Starting haproxy ... 
Starting l2 ... done
Attaching to pwd, haproxy, l2
haproxy    | [NOTICE]   (1) : haproxy version is 2.5.0-f2e0833

打开浏览器进行访问

点击Start并新增实例

内外穿透

如果配置了内网穿透

则需要编辑文件api.go,在api.go文件的 config.ParseFlags()下面添加config.PlaygroundDomain = “穿透地址”

运行并访问

[root@vm1 play-with-docker]# docker-compose up
