4docker 20.10.11
5Terraform v1.1.8

1(1)下载jdk软件
2[root@devops ~]#wget https://mirrors.tuna.tsinghua.edu.cn/AdoptOpenJDK/8/jdk/x64/linux/OpenJDK8U-jdk_x64_linux_hotspot_8u322b06.tar.gz --no-check-certificate

 1（2）配置jdk环境
 2[root@devops ~]#tar zxf OpenJDK8U-jdk_x64_linux_hotspot_8u322b06.tar.gz -C /usr/local/
 3[root@devops ~]#cd /usr/local/jdk8u322-b06/
 4[root@devops jdk8u322-b06]#pwd
 5/usr/local/jdk8u322-b06
 6[root@devops jdk8u322-b06]#vim /etc/profile
 7export JAVA_HOME=/usr/local/jdk8u322-b06
 8export PATH=$JAVA_HOME/bin:$PATH
 9[root@devops jdk8u322-b06]#source /etc/profile
10
11（3）验证
12[root@devops jdk8u322-b06]#java -version
13openjdk version "1.8.0_322"
14OpenJDK Runtime Environment (Temurin)(build 1.8.0_322-b06)
15OpenJDK 64-Bit Server VM (Temurin)(build 25.322-b06, mixed mode)

 1（1）上传下载好的二进制包到服务器
 2[root@devops ~]#ll -h terraform_1.1.8_linux_amd64.zip 
 3-rw-r--r-- 1 root root 18M Apr 12 19:59 terraform_1.1.8_linux_amd64.zip
 4[root@devops ~]#unzip terraform_1.1.8_linux_amd64.zip 
 5Archive:  terraform_1.1.8_linux_amd64.zip
 6  inflating: terraform
 7[root@devops ~]#ll -h terraform
 8
 9（2）移动二进制文件到PATH路径
10-rwxr-xr-x 1 root root 61M Apr  8 00:54 terraform
11[root@devops ~]#mv terraform /usr/local/bin/
12
13（3）验证
14[root@devops ~]#terraform version
15Terraform v1.1.8
16on linux_amd64  

1[root@devops ~]#mkdir -p /data/devops4/jenkins_home
2[root@devops ~]#chmod -R 777 /data/devops4/jenkins_home/

 1### 定义docker镜像(jenkins.tf)
 2resource "docker_image" "jenkins" {
 3  name         = "jenkins/jenkins:2.332.2-centos7-jdk8"
 4  keep_locally = true  //资源销毁后不会删除本地镜像
 5}
 6
 7resource "docker_container" "jenkins" {
 8  image = docker_image.jenkins.name
 9  name  = "devops_tutorial"
10  ports {
11    internal = 8080
12    external = 8080
13  }
14  ports {
15      internal = 50000
16      external = 50000
17  }
18
19  volumes{
20      container_path = "/var/jenkins_home"
21      host_path = "/data/devops4/jenkins_home" //这个目录要提前在主机里进行创建
22  }
23}

 1# 定义provider（main.tf）
 2terraform {
 3  required_providers {
 4    docker = {
 5      source = "kreuzwerker/docker"
 6      version = "~> 2.13.0"
 7      }
 8  }
 9}
10
11provider "docker" {}

1[root@devops remote-vscode]#terraform init

1[root@devops remote-vscode]#terraform plan

1[root@devops remote-vscode]#terraform apply

1[root@devops remote-vscode]#docker ps |grep jenkins

 1管理docker容器
 2	- docker命令
 3	- docker-compose
 4	- 本地用tf来管理docker环境: tf有一个provider，一个插件，它是支持管docker的。所以，我们后面一个tf模板就把整个实验环境就跑起来了，最终可以一键拉起来。
 5	
 6但是TF比较厉害，它的插件支持k8s，就是你不想使用yaml来管理k8s里的资源，那么TF也是可以通过插件来管理k8s里的资源的。此时，就行就需要你来写Tf的provider插件来着，但是还是yaml好使。
 7
 8这个TF太牛了！！(tf：管理你的基础设施的。)
 9但这个工具也存在一定的危险性，我可以一键去创建，也可以一键去销毁。
10老师大力推荐！
