1.环境
1主机
表1-1 主机
主机系统软件备注pipepointLinuxTerraform 1.6.6 2.Terraform查看版本
1查看Terraform版本
terraform -v 3.Linux主机安装Docker
(1)安装Docker
① 阿里云镜像加速将XXXXXXXX改为自己的即可 https://XXXXXXXX.mirror.aliyuncs.com,
1安装
yum -y install wget wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum -y install docker-ce2配置cgroup驱动及镜像下载加速器
cat /etc/docker/daemon.json EOF
{exec-opts: [native.cgroupdriversystemd],registry-mirrors: [https://XXXXXXXX.mirror.aliyuncs.com,https://registry.docker-cn.com,https://docker.mirrors.ustc.edu.cn,https://dockerhub.azk8s.cn,http://hub-mirror.c.163.com]
}
EOF3自启动
systemctl enable docker systemctl start docker systemctl status docker docker info|grep systemd ② 安装docker
③ 配置镜像加速 ④ 开机自启动服务 2查看版本
docker -v 4.Terraform使用本地编译In-house的Providers
1编写配置文件
vim .terraformrcprovider_installation {filesystem_mirror {path /usr/share/terraform/providersinclude [registry.terraform.io/*/*]}
} 2Terraform模板(docker)
Terraform Registry
USE PROVIDER
terraform {required_providers {docker {source kreuzwerker/dockerversion 3.0.2}}
}provider docker {# Configuration options
} Example Usage
terraform {required_providers {docker {source kreuzwerker/dockerversion 3.0.2}}
}provider docker {host unix:///var/run/docker.sock
}# Pulls the image
resource docker_image ubuntu {name ubuntu:latest
}# Create a container
resource docker_container foo {image docker_image.ubuntu.image_idname foo
}
(3) 下载软件包
https://github.com/kreuzwerker/terraform-provider-docker/releases (4) 创建目录
mkdir -p /usr/share/terraform/providers/registry.terraform.io/kreuzwerker/docker/3.0.2/linux_amd64 5解压软件包
unzip terraform-provider-docker_3.0.2_linux_amd64.zip 6tree递归查看目录 (将软件包按递归目录放置)
tree -s /usr/share/terraform/ 5.Docker-CE 开启远程API
1修改配置文件
vim /usr/lib/systemd/system/docker.service
……
ExecStart/usr/bin/dockerd --containerd/run/containerd/containerd.sock -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock -H fd://
…… 2重新加载配置及重启服务
systemctl daemon-reload systemctl restart docker 3测试API
curl http://127.0.0.1:2375/version6. Linux主机拉取镜像
1dockerhub 查看镜像
https://hub.docker.com/r/jenkins/jenkins
docker pull jenkins/jenkins 2拉取镜像
docker pull jenkins/jenkins 3查看镜像
docker images7.Terraform 使用 dynamic动态内联块 创建资源
1查看目录
tree -s ~/tf-meta/dynamic/2主配置文件
main.tf Docker Provider用于与 Docker 容器和镜像进行交互它使用 Docker API 来管理 Docker 容器的生命周期。
vim main.tfprovider docker {host tcp://127.0.0.1:2375
}resource docker_image jenkins {name jenkins/jenkins:latestkeep_locally true //销毁时不删除本地镜像
}locals {jenkins_ports [ { internal 8085external 8085}, { internal 50000external 50000} ]
}resource docker_container jenkins {image docker_image.jenkins.namename jenkins123user rootdynamic ports {for_each local.jenkins_portscontent {internal ports.value.internalexternal ports.value.externalip 0.0.0.0protocol tcp} }volumes {container_path /var/jenkins_homehost_path /tmp/jenkinshome}depends_on [ docker_image.jenkins]
}3版本配置文件
versions.tf
vim versions.tfterraform {required_providers {docker { source kreuzwerker/dockerversion 3.0.2} }
}(4) 格式化代码
terraform fmt (5) 初始化
terraform init (6) 验证
terraform validate (7)计划与预览 terraform plan (8) 申请资源
terraform apply yes (9)展示资源
terraform show (11)查看docker进程
docker ps (12) 检查容器 docker inspect 924c951bff6013查看容器日志
docker logs -f jenkins123(14) 查看监听端口
http://192.168.204.233:50000/ (15) 销毁资源
terraform destroy yes (16) 查看docker进程
docker ps
资源已删除 二、问题 1.Terraform 计划资源失败 (无效provider)
1报错

未配置docker的provider
3解决方法
配置docker的provider 成功 2.Terraform 申请资源失败 (端口占用)
1报错
申请容器为8080端口 │ Error: Unable to start container: Error response from daemon: driver failed programming external connectivity on endpoint jenkins123 (7b6aea49d069b5eb7693528fd8754026960ea22381ec2ccc2927a0029709d552): Error starting userland proxy: listen tcp4 0.0.0.0:8080: bind: address already in use

端口被占用。
3解决方法
查看当前占用端口命令。
netstat -tanlp 方法一杀死进程(注意不是杀死端口而是pid的端口)
8080 端口的进程为64353
8081端口的进程为63265
kill 64353进程 (自己的pid端口)kill 63265进程 (自己的pid端口)
方法二(这里采用此方法)
更改Terraform配置文件端口为8085。 成功
