Docker部署SpringBoot的兩種方法
更新時(shí)間：2023年10月31日 17:04:08 作者：六月·飛雪
Docker是一種流行的容器化技術(shù),可以幫助開發(fā)人員更輕松地構(gòu)建、部署和運(yùn)行應(yīng)用程序,Spring?Boot是一種快速開發(fā)框架,可以幫助開發(fā)人員更快地構(gòu)建應(yīng)用程序,本文主要介紹了Docker部署SpringBoot的兩種方法,感興趣的可以了解一下
1.手工方式
1.1.準(zhǔn)備Springboot jar項(xiàng)目
將項(xiàng)目打包成jar
1.2.編寫Dockerfile
FROM java:8 VOLUME /tmp ADD elk-web-1.0-SNAPSHOT.jar elk.jar EXPOSE 8080 ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/elk.jar"]
FROM：表示基礎(chǔ)鏡像，即運(yùn)行環(huán)境 VOLUME /tmp創(chuàng)建/tmp目錄并持久化到Docker數(shù)據(jù)文件夾，因?yàn)镾pring Boot使用的內(nèi)嵌Tomcat容器默認(rèn)使用/tmp作為工作目錄 ADD：拷貝文件并且重命名(ADD elk-web-1.0-SNAPSHOT.jar elk.jar 將應(yīng)用jar包復(fù)制到/elk.jar) EXPOSE：并不是真正的發(fā)布端口，這個(gè)只是容器部署人員與建立image的人員之間的交流，即建立image的人員告訴容器布署人員容器應(yīng)該映射哪個(gè)端口給外界 ENTRYPOINT：容器啟動(dòng)時(shí)運(yùn)行的命令，相當(dāng)于我們?cè)诿钚兄休斎雑ava -jar xxxx.jar，為了縮短 Tomcat 的啟動(dòng)時(shí)間，添加java.security.egd的系統(tǒng)屬性指向/dev/urandom作為 ENTRYPOINT
1.3.構(gòu)建容器
[root@VM_0_15_centos elk]# docker build -t elk . Sending build context to Docker daemon 14.43 MB Step 1/5 : FROM java:8 Trying to pull repository docker.io/library/java ... 8: Pulling from docker.io/library/java 5040bd298390: Pull complete fce5728aad85: Pull complete 76610ec20bf5: Pull complete 60170fec2151: Pull complete e98f73de8f0d: Pull complete 11f7af24ed9c: Pull complete 49e2d6393f32: Pull complete bb9cdec9c7f3: Pull complete Digest: sha256:c1ff613e8ba25833d2e1940da0940c3824f03f802c449f3d1815a66b7f8c0e9d Status: Downloaded newer image for docker.io/java:8 ---> d23bdf5b1b1b Step 2/5 : VOLUME /tmp ---> Running in 0aec2dc2f98c ---> a52e844f25d4 Removing intermediate container 0aec2dc2f98c Step 3/5 : ADD elk-web-1.0-SNAPSHOT.jar elk.jar ---> 3ba2f4fdddda Removing intermediate container 860a0f748a23 Step 4/5 : EXPOSE 8080 ---> Running in 1d3331cc2be6 ---> e9ac33d26ce0 Removing intermediate container 1d3331cc2be6 Step 5/5 : ENTRYPOINT java -Djava.security.egd=file:/dev/./urandom -jar /elk.jar ---> Running in d354f8ee2af5 ---> 8937e1ade6c7 Removing intermediate container d354f8ee2af5 Successfully built 8937e1ade6c7
1.4.運(yùn)行容器
docker run -di --name 容器名稱 -p 8080:8080 鏡像名稱
其中-d表示后臺(tái)運(yùn)行容器，這也就自然地解決的Spring Boot不支持后臺(tái)運(yùn)行應(yīng)用程序的問題。-p 8080:8080表示將容器內(nèi)部的8080端口映射到宿主機(jī)器的8080端口，這樣就可以通過宿主機(jī)器直接訪問應(yīng) 用。--name 給容器取一個(gè)容易記住的名字方便日后管理。
在公眾號(hào)頂級(jí)架構(gòu)師后臺(tái)回復(fù)“架構(gòu)整潔”，獲取一份驚喜禮包。
[root@VM_0_15_centos elk]# docker run -di --name myspringboot -p 8080:8080 8937e1ade6c7 04d6b2c347950a10c95a039c94a3e51d717e516dd8c3c742e3197687dfcf5523 [root@VM_0_15_centos elk]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 04d6b2c34795 8937e1ade6c7 "java -Djava.secur..." 8 seconds ago Up 7 seconds 0.0.0.0:8080->8080/tcp myspringboot [root@VM_0_15_centos elk]#
1.5.查看運(yùn)行日志
docker logs -f --tail=100 容器名稱
[root@VM_0_15_centos elk]# docker logs -f --tail=100 04d6b2c34795

1.6.訪問測(cè)試
2.Docker遠(yuǎn)程連接并且使用idea一鍵部署
2.1.配置docker遠(yuǎn)程連接端口
首先編輯我們服務(wù)器上的docker文件
vim /usr/lib/systemd/system/docker.service
修改以ExecStart開頭的行（centos 7）：添加
-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock \
修改后保存文件，然后重啟docker
systemctl daemon-reload service docker restart
重啟之后測(cè)試遠(yuǎn)程連接是否正常，這里的2375是之前配置的端口
curl http://localhost:2375/version
看到返回信息基本上就沒有問題了
[root@VM_0_15_centos elk]# curl http://localhost:2375/version
{"Version":"1.13.1","ApiVersion":"1.26","MinAPIVersion":"1.12","GitCommit":"7f2769b/1.13.1","GoVersion":"go1.10.3","Os":"linux","Arch":"amd64","KernelVersion":"3.10.0-957.21.3.el7.x86_64","BuildTime":"2019-09-15T14:06:47.565778468+00:00","PkgVersion":"docker-1.13.1-103.git7f2769b.el7.centos.x86_64"}
然后開啟端口，或者關(guān)閉防火墻，二者選其一即可
firewall-cmd --zone=public --add-port=2375/tcp --permanent chkconfig iptables off
然后打開瀏覽器測(cè)試將之前的localhost修改為你的ip
2.2.使用idea連接到docker
首先下載docker插件，idea 自帶了docker插件。如果沒有插件可以選擇安裝docker插件
然后配置docker地址，在你的File | Settings | Build, Execution, Deployment | Docker
配置完成鏈接之后，出現(xiàn)了框中的內(nèi)容即可.
鏈接成功之后會(huì)列出容器和鏡像!
配置阿里云鏡像加速器：
2.3.docker-maven-plugin 介紹
在我們持續(xù)集成過程中，項(xiàng)目工程一般使用 Maven 編譯打包，然后生成鏡像，通過鏡像上線，能夠大大提供上線效率，同時(shí)能夠快速動(dòng)態(tài)擴(kuò)容，快速回滾，著實(shí)很方便。docker-maven-plugin 插件就是為了幫助我們?cè)贛aven工程中，通過簡(jiǎn)單的配置，自動(dòng)生成鏡像并推送到倉庫中。
