Docker自動化部署實戰

簡述

初創公司,最簡單高效的前段自動化部署方案,分享給大家.跟著我一步步操作有問題評論區提問

準備

• 一臺Centos7至少內存為4G的機器。

安裝Docker

<code>
curl
 -sSL https://get.docker.com/ | sh
/<code>

安裝Gitlab

<code>sudo yum 
install
 -y git vim gcc glibc-
static
 telnet
sudo yum 
install
 -y curl policycoreutils-python openssh-
server
sudo systemctl 
enable
 sshd
sudo systemctl 
start
 sshd
sudo yum 
install
 postfix
sudo systemctl 
enable
 postfix
sudo systemctl 
start
 postfix
/<code>

• 新建 /etc/yum.repos.d/gitlab-ce.repo 文件

<code>
[gitlab-ce]
name
=Gitlab CE Repository
baseurl
=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el
$releasever
/
 
gpgcheck
=
0
enabled
=
1
/<code>

開始安裝

<code>
sudo
 EXTERNAL_URL=
"http://www.syappmp.com"
 yum install -y gitlab-ce
sudo gitlab-ctl reconfigure
/<code>

域名設置一個內網可以訪問到這臺機器IP的域名訪問
http://www.yunliantaida.com 可以看到你安裝的gitlab設置好用戶名密碼

安裝gitlab ci runner

<code>
curl
 
-L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.rpm.sh | sudo bash
sudo
 
yum install gitlab-ci-multi-runner -y
sudo
 
usermod -aG docker gitlab-runner
sudo
 
service docker restart
sudo
 
gitlab-ci-multi-runner status
/<code>

返回 gitlab-runner: Service is running! 標示安裝成功

GitLab CI設置

• 關注我待更新

創建NuxtJS

• 開發機安裝好NodeJS, Yarn具體安裝百度有很多
• 直接場景Nuxt項目

<code>
yarn
 
create nuxt-app yunliantaida
cd
 
yunliantaida
npm
 
run dev
/<code>

應用現在運行在 http://localhost:3000 上運行。

編寫DockerFile

• nutx項目目錄下新建Dockerfile

<code>
FROM
 
node:10.16.3-alpine
ENV
 
NODE_ENV=production 

ENV
 
HOST 0.0.0.0
RUN
 
mkdir -p /nuxt
COPY
 
.nuxt/  /nuxt/.nuxt
COPY
 
static/  /nuxt/static
COPY
 
nuxt.config.js  /nuxt/
COPY
 
package.json  /nuxt/
WORKDIR
 
/nuxt
EXPOSE
 
3000
RUN
 
ls
RUN
 
npm config set registry https://registry.npm.taobao.org
RUN
 
npm install
CMD
 
["npm", "start"]
/<code>

編寫DockerRun腳本

• nutx項目目錄下新建dockerrun.sh

<code> 
IMAGE_NAME=nginx/www.syappmp.com
APP_NAME=www.syappmp.com
APP_VERSION=1.0
 
is_exist
() {
  pid=$(docker ps -a --filter name=
${APP_NAME}
 | awk 
'{if (NR>1){print $1}}'
)
   
  
if
 [ -z 
"
${pid}
" ]; 
then
    
return
 1
  
else
    
return
 0
  
fi
}
is_images_exist
() {
  pidDockerImages=$(docker images | grep 
''
 | awk 
'{print $3}'
)
  
if
 [ -z 
"
${pidDockerImages}
" ]; 
then
    
return
 1
  
else
     
return
 0
  
fi
}
is_images_exist
if
 [ $? -eq 
"0"
 ]; 
then
  docker rmi 
${pidDockerImages}
fi
is_exist
if
 [ $? -eq 
"0"
 ]; 
then
  
echo
 
">>> Dcoker is already running PID=
${pid}
 <<
  docker stop 
${pid}
  docker rm 
${pid}
fi
docker run --name 
${APP_NAME}
 -d -p 8020:80 
${IMAGE_NAME}
 &
echo
 
">>> start 
${APP_NAME}
:
${APP_VERSION}
 running successed PID=$! <<
/<code>

• nutx項目目錄下新建 .gitlab-ci.yml (注意前面的.要複製)

<code>
stages
:

    
build
    
deploy

build
:

  
stage
: 
build
  
tags
:

      
test
  
script
:

 
      
npm install
      
npm run build
      
docker build -t nginx/www.syappmp.com .
run
:

  
stage
: 
deploy
  
tags
:

      
test
  
script
:

 
      
sh dockerrun.sh

/<code> 

• 將Nutx項目上傳到GitLab上,每次提交推送git push會自動化打包編譯部署運行Docker容器
• 訪問 http://內網服務IP:8020
• 如果有同學GitLab不會用可以百度一下
