docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

1.手工方式

1.1.準(zhǔn)備Springboot jar項(xiàng)目

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

將項(xiàng)目打包成jar

1.2.編寫(xiě)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

1.4.運(yùn)行容器

docker?run?-di?--name?容器名稱(chēng)?-p?8080:8080?鏡像名稱(chēng)

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(wèn)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(guò)宿主機(jī)器直接訪(fǎng)問(wèn)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。

1.6.訪(fǎng)問(wèn)測(cè)試

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

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(kāi)頭的行（centos 7）：添加

-H?tcp://0.0.0.0:2375?-H?unix:///var/run/docker.sock?\

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

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(méi)有問(wèn)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(kāi)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(kāi)瀏覽器測(cè)試將之前的localhost修改為你的ip

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

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(méi)有插件可以選擇安裝docker插件

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

然后配置docker地址，在你的File | Settings | Build, Execution, Deployment | Docker

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

配置完成鏈接之后，出現(xiàn)了框中的內(nèi)容即可.

docker 啟動(dòng)springboot,架構(gòu),docker,spring boot,java

鏈接成功之后會(huì)列出容器和鏡像!

2.3.docker-maven-plugin 介紹

在我們持續(xù)集成過(guò)程中，項(xiàng)目工程一般使用 Maven 編譯打包，然后生成鏡像，通過(guò)鏡像上線(xiàn)，能夠大大提供上線(xiàn)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(guò)簡(jiǎn)單的配置，自動(dòng)生成鏡像并推送到倉(cāng)庫(kù)中。
