1返弹、前言

本文記錄了通過(guò)docker锈玉、docker-compose部署code-server、mysql,搭建在線開(kāi)發(fā)環(huán)境的過(guò)程义起，綜合體驗(yàn)很爽拉背，適合小規(guī)模開(kāi)發(fā)團(tuán)隊(duì)使用。

下一步準(zhǔn)備逐步嘗試結(jié)合git默终、jenkins椅棺、java代碼檢查犁罩、sql代碼檢查、k8s两疚、helm床估，實(shí)現(xiàn)一套在線開(kāi)發(fā)、代碼評(píng)審诱渤、編譯丐巫、打包、測(cè)試勺美、部署的devops递胧。

安裝環(huán)境：
vmware hypervision、centos 8

2励烦、安裝docker

# 獲取阿里云yum鏡像文件
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
# 非阿里云主機(jī)需要替換地址
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
# 重建 yun cache
yum clean all
yum makecache
# 使用yum升級(jí)系統(tǒng)
yum update  --nobest

#刪除舊的docker
sudo yum remove docker                   docker-client                   docker-client-latest                   docker-common                   docker-latest                   docker-latest-logrotate                   docker-logrotate                   docker-engine

# 安裝最新版的containerd.io
dnf install https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/nightly/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm

#安裝Yum源管理工具
yum install -y yum-utils device-mapper-persistent-data lvm2

#安裝阿里云的docker-ce源
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache

#安裝docker-ce

yum install docker-ce docker-ce-cli

#配置docker 鏡像
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://heusyzko.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

3谓着、安裝 docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

4、準(zhǔn)備vs的settings.json配置文件

vi settings.json

{
    // Nomal
    "editor.fontSize": 18,
    "workbench.iconTheme": "vscode-icons",
    "vsicons.dontShowNewVersionMessage": true,
    "editor.minimap.enabled": true,
    "workbench.colorTheme": "Visual Studio Light",
    "workbench.startupEditor": "newUntitledFile",
    // 保存格式化
    "files.autoSave": "onFocusChange",
    "editor.formatOnPaste": true,
    "editor.formatOnType": true,
    // Env
    "java.home": "/usr/local/jdk1.8.0_261",
    "maven.executable.path": "/usr/local/apache-maven-3.6.0/bin/mvn",
    "java.configuration.maven.userSettings": "/usr/local/apache-maven-3.6.0/conf/settings.xml",
    "maven.terminal.customEnv": [
        {
            "environmentVariable": "JAVA_HOME",
            "value": "/usr/local/jdk1.8.0_261"
        }
    ],
    "python.formatting.provider": "yapf",
    "python.autoComplete.addBrackets": true,
    "python.jediEnabled": false,
    "python.linting.pylintEnabled": true,
    // exclude file
    "files.exclude": {
        "**/.classpath": true,
        "**/.project": true,
        "**/.settings": true,
        "**/.factorypath": true,
        "**/.vscode": true,
        "**/.empty": true,
    },
    // code-runner
    "code-runner.clearPreviousOutput": true,
    "code-runner.runInTerminal": false,
    // 執(zhí)行文件的腳本坛掠，可以使用絕對(duì)路徑
    "code-runner.executorMap": {
        "python": "/usr/local/anaconda3/python3",
        "java": "cd $dir && javac $fileName && java $fileNameWithoutExt",
    },
}

5赊锚、編輯Dockerfile文件

vs code的插件建議自行在官方市場(chǎng)下載后,放到extensions目錄。
下載地址：
https://marketplace.visualstudio.com/

Java開(kāi)發(fā)環(huán)境常用插件如下：

FROM codercom/code-server:latest
# COPY JDK和MAVEN
COPY jdk1.8.0_261 /usr/local/jdk1.8.0_261/
COPY apache-maven-3.6.3 /usr/local/apache-maven-3.6.3/
# code-server配置文件 插件
 COPY extensions /root/.local/share/code-server/extensions/
 COPY settings.json /root/.local/share/code-server/User/
# Env
ENV JAVA_HOME=/usr/local/jdk1.8.0_261 \
    JRE_HOME=/usr/local/jdk1.8.0_261/jre \
    PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin \
    CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib \
    MAVEN_HOME=/usr/local/apache-maven-3.6.3

ENV PATH=$MAVEN_HOME/bin:$PATH

WORKDIR /home/coder/project
# 容器啟動(dòng)code-server：指定插件目錄域滥，指定中文纵柿，指定免密登錄
ENTRYPOINT ["code-server","--locale","zh-cn","--host","0.0.0.0","--port","8080", "--user-data-dir", "/home/coder","--cert",""]

6、build 自定義docker image

docker build -t boshine/code-server:latest --rm=true .

7启绰、編輯docker-compose

如果團(tuán)隊(duì)多人一起協(xié)同開(kāi)發(fā)昂儒，建議每個(gè)人部署一個(gè)code-server容器，實(shí)現(xiàn)環(huán)境隔離委可。
配合github/gitee/gitlab等代碼管理服務(wù)器使用渊跋。

version: "3"

services:
  luocoder:
    container_name: luocoder
    image: boshine/code-server
    links:
      - db
    depends_on:
      - db
    ports:
      - "8080:8080"
      - "8088:8088"
    volumes:
      - "/root/code-server:/home/"
      - "/root/code-server/root:/root"
      - "/root/code-server/tmp:/tmp"
    environment:
      PASSWORD: 12345678
    restart: always
    privileged: true
    user: root

  db:
    container_name: mysql
    image: mysql:5.7
    ports:
      - "3306:3306"
    volumes:
      - "/root/mysql/data:/var/lib/mysql"
      - "/root/mysql/conf:/etc/mysql"
      - "/root/mysql/logs:/var/log/mysql"
    command: [
            '--character-set-server=utf8mb4',
            '--collation-server=utf8mb4_unicode_ci',
            '--max_connections=3000'
    ]
    environment:
      MYSQL_ROOT_PASSWORD: 12345678
    restart: always
    privileged: true
    user: root

8、使用docker-compose運(yùn)行coder容

docker-compose up -d
