docker分离部署springboot并外置静态文件

it2024-01-20 70

docker部署springboot项目时，每次上传war/jar包耗时耗力，并且每次都要修改配置文件，所以用docker部署时，将springboot项目打包时将项目的代码、静态文件、配置文件、lib分离，每次升级只需上传修改的代码即可，同时将静态文件等外挂到服务器，修改时只需修改完重启容器应用即可，无需重新build镜像。

配置打包springboot项目

1. 修改pom.xml文件

设定打成jar包

1 2 3 4 复制 <groupId>com.blog</groupId> <artifactId>MyBlog</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging>

build标签下设定打包的名称

1 复制 <finalName>MyBlog</finalName>

build plugins标签下配置打包成jar

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 复制  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <excludes> <exclude>**/*.properties</exclude> <exclude>**/*.xml</exclude> </excludes> <archive> <manifest> <mainClass>com.blog.MyBlogApplication</mainClass> <addClasspath>true</addClasspath> <classpathPrefix>lib/</classpathPrefix> </manifest> <manifestEntries> <Class-Path>./</Class-Path> </manifestEntries> </archive> <outputDirectory>${project.build.directory}</outputDirectory> </configuration> </plugin>

build plugins标签下配置打包依赖lib

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 复制  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy-dependencies</id> <phase>prepare-package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputDirectory>${project.build.directory}/lib</outputDirectory> </configuration> </execution> </executions> </plugin>

build plugins标签下配置打包resource

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 复制  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <executions> <execution> <id>copy-resources</id> <phase>prepare-package</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <encoding>UTF-8</encoding> <resources> <resource> <directory>src/main/resources</directory> </resource> </resources> <outputDirectory>${project.build.directory}/</outputDirectory> </configuration> </execution> </executions> </plugin>

build resources标签下配置打包时将jsp文件拷贝到META-INF目录

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 复制 <resources>  <resource>  <directory>src/main/webapp</directory>  <targetPath>META-INF/resources</targetPath> <includes> <include>**/**</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/**</include> </includes> <filtering>false</filtering> </resource> </resources>

2. maven build springboot项目

命令或者ideclean install

配置dockerfile

1 2 3 4 5 6 7 复制 FROM frolvlad/alpine-oraclejdk8:slim VOLUME /tmp ARG DEPENDENCY=MyBlog COPY ${DEPENDENCY}/BOOT-INF/lib /app/lib COPY ${DEPENDENCY}/META-INF /app/META-INF COPY ${DEPENDENCY}/BOOT-INF/classes /app ENTRYPOINT ["java","-cp","app:app/lib/*","com.blog.MyBlogApplication"] FROM jdk，运行jar文件VOLUME /tmp springboot内置tomcat存放ARG 解压springboot的文件夹COPY 将解压项目中的静态文件等copy到容器中指定位置，用于指定外挂ENTRYPOINT 中com.blog.MyBlogApplication为springboot启动类

使用docker部署项目

1. 在linux服务器上创建文件夹blog

2. 将解压的springboot项目、Dockerfile文件传输到服务器的blog文件夹

3. docker build镜像

进入linux的blog文件夹执行docker命令将springboot项目build成镜像 1 复制 docker build -t blog:1.1 . 注意语句结束后的“.”,不可省略

4. 创建容器，并外挂静态文件

1 复制 docker run --name blog -it -p 8080:8081 -v /etc/localtime:/etc/localtime -v /etc/config/blog/lib:/app/lib -v /etc/config/blog/static:/app/static -v /etc/config/blog/templates:/app/templates -v /etc/config/blog/config:/app/config -v /home/app/blog/editormd/images/:/home/app/blog/editormd/images/ -d blog:1.1 –name容器名称-p 8081:8080 端口映射，8081服务器端口映射到容器的8080端口-v /etc/config/blog/static:/app/static 将容器中/app/static（静态文件）挂载到服务器的/etc/config/blog/static目录下，其他几个-v命令也是如此。

-d blog 镜像名称

到此部署成功。
