03、使用docker-compose安裝軟件

## 創建docker-compose基礎目錄
mkdir -p /usr/local/docker

1、安裝mysql

mkdir -p /usr/local/docker/mysql

1.1、docker-compose.yml內容

version: '3.1'
services:
  db: 
   image: mysql
   restart: always
   environment:
    MYSQL_ROOT_PASSWORD: root
   command:
    --default-authentication-plugin=mysql_native_password
    --character-set-server=utf8mb4
    --collation-server=utf8mb4_general_ci
    --explicit_defaults_for_timestamp=true
    --lower_case_table_names=1
   ports:
    - 3306:3306
   volumes:
    - ./data:/var/lib/mysql
  adminer:
   image: adminer
   restart: always
   ports:
    - 9999:8080

1.2、創建docker-compose.yml文件

## 在/usr/local/docker/mysql目錄創建docker-compose.yml文件並複製粘貼第三部內容到這個文件中
vi /usr/local/docker/mysql/docker-compose.yml

##輸入冒號，接着輸入 set paste ,再輸入i 進入帶格式粘貼模式

1.3、保存退出

wq!

1.4、運行容器

docker-compose up -d

1.5、銷燬容器

docker-compose down

2、安裝gitlab

mkdir -p /usr/local/docker/gitlab

2.1、docker-compose.yml內容

version: '3.1'
services:
  web:
    image: 'twang2218/gitlab-ce-zh'
    restart: always
    hostname: '192.168.100.102'
    environment:
      TZ: 'Asia/Shanghai'
      GITLAB_OMNIBUS_CONFIG: |
        external_url 'http://192.168.100.102'
        gitlab_rails['gitlab_shell_ssh_port'] = 2222
        unicorn['port'] = 8888
        nginx['listen_port'] = 80
    ports:
      - '80:80'
      - '443:443'
      - '2222:22'
    volumes:
      - ./config:/etc/gitlab
      - ./data:/var/opt/gitlab
      - ./logs:/var/log/gitlab

啓動後訪問：http://192.168.100.102

3、安裝nexus3

mkdir -p /usr/local/docker/nexus

3.1、docker-compose.yml內容

version: '3.1'
services: 
  nexus: 
    restart: always
    image: sonatype/nexus3
    container_name: nexus
    ports:
     - 8081:8081
    volumes:
     - nexus-data:/nexus-data
volumes:
  nexus-data: 

啓動後訪問：http://192.168.100.102:8081

根據提示找到密碼複製出來

3.2、maven使用nexus

在setting.xml配置認證信息，在<servers>節點添加如下配置：

<server>
    <id>releases</id>
    <username>admin</username>
    <password>admin123</password>
</server>
<server>
    <id>snapshots</id>
    <username>admin</username>
    <password>admin123</password>
</server>

在pom.xml添加部署配置

<distributionManagement>
    <repository>
        <id>releases</id>
        <name>Nexus Release Repository</name>
        <url>http://192.168.100.101:8081/repository/maven-releases/</url>
    </repository>
    <snapshotRepository>
        <id>snapshots</id>
        <name>Nexus Snapshot Repository</name>
        <url>http://192.168.100.101:8081/repository/maven-snapshots/</url>
    </snapshotRepository>
</distributionManagement>

在pom.xml設置代理倉庫

<repositories>
     <repository>
         <id>nexus</id>
         <name>Nexus Repository</name>
         <url>http://192.168.100.101:8081/repository/maven-public/</url>
         <snapshots>
             <enabled>true</enabled>
         </snapshots>
         <releases>
             <enabled>true</enabled>
         </releases>
     </repository>
</repositories>
<pluginRepositories>
    <pluginRepository>
        <id>nexus</id>
        <name>Nexus Plugin Repository</name>
        <url>http://192.168.100.101:8081/repository/maven-public/</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
        <releases>
            <enabled>true</enabled>
        </releases>
    </pluginRepository>
</pluginRepositories>

配置pom.xml的build信息

<build>
    <finalName>myshop</finalName>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-deploy-plugin</artifactId>
            <version>2.8.2</version>
            <configuration>

                    <goals>
                        <goal>jar</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <!-- 資源文件拷貝插件 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <version>3.1.0</version>
            <configuration>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
        <!--Java 編譯插件-->

                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
        <!-- 打包時跳過測試 -->

            <configuration>
                <skipTests>true</skipTests>
            </configuration>
        </plugin>
    </plugins>
</build>

4、安裝Harbor鏡像倉庫

4.1、下載安裝包：https://github.com/goharbor/harbor/releases

4.2、上傳到 /usr/local/docker/目錄

4.3、解壓 tar -zxvf harbor-offline-installer-v1.9.1-rc1.tgz

4.4、進入到harbor目錄修改harbor.yml文件

hostname: 192.168.100.102
http:
  port: 8090
harbor_admin_password: 12345678

4.5、執行 install.sh

./install.sh

啓動後訪問：http://192.168.100.101:8090 用戶名：admin 密碼：Harbor12345

4.6、配置客戶端

##沒有此文件就創建
vim /etc/docker/daemon.json

{
  "registry-mirrors":[
     "https://registry.docker-cn.com"
  ],
  "insecure-registries":[
   "192.168.100.101:8090"
  ]
}
注意：該文件必須符合JSON規範，否則docker將不能啓動

4.7、重啓服務

systemctl daemon-reload
systemctl restart docker

4.8、檢查私服配置

docker info

4.9 、製作鏡像提交到harbor倉庫

##拉取nginx
docker pull nginx
## 在項目中標記鏡像   
## docker tag SOURCE_IMAGE[:TAG] 192.168.100.101:8090/itchao-saas/IMAGE[:TAG]
docker tag nginx:latest 192.168.100.101:8090/itchao-saas/nginx:latest
## 登錄
docker login 192.168.100.101:8090 -u admin -p Harbor12345
## 推送鏡像到當前項目
## docker push 192.168.100.101:8090/itchao-saas/IMAGE[:TAG]
docker push 192.168.100.101:8090/itchao-saas/nginx:latest

5、docker-compose設置網絡

預先創建一個網絡

##創建網絡
docker network create <Network Name>
##查看已存在的網絡
docker network list

在docker-compose.yml中指定網絡

networks:
  default:
    external:
      name: myapp
