Automatically build Web applications using Gitlab, MAVEN, Docker __web

Every time a team builds an application, it is troublesome and error-prone to export the war package through eclipse/sts, then upload it to the server, copy it to Tomcat, and manually stop/start the Tomcat service.

I used Gitlab, MAVEN, Docker tools, plus a shell script, to make a simple automated build tool.

1. First install JDK version 64, MAVEN, modify/etc/profile file as follows:

java_home=/home/git/jdk1.8.0_161
jre_home= $JAVA _home/jre
#CLASSPATH =.: $JAVA _home/lib: $JAVA _home/jre/ Lib
classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/rt.jar: $JAVA _home/lib/tools.jar: $JRE _home/lib/rt.jar
Export maven_home=/home/git/src/apache-maven-3.5.2

Path= $JAVA _home/bin:/home/git/apache-maven-3.5.2/bin: $PATH
export java_home CLASSPATH jre_home PATH
tz= ' Asia/shanghai '; Export TZ

2. Install Docker and use Docker to install Gitlab, you can refer to my previous blog. https://blog.csdn.net/jzd1997/article/details/79297250

2.1 Download the Tomcat image and start.

sudo docker pull Tomcat
sudo docker cp/etc/localtime gitlab:/etc/localtime   #解决容器和主机时间不一致问题

sudo docker run -d-p 8080:8080--name Customer Tomcat

After startup, you can enter the Docker Tomcat instance to confirm the Tomcat storage location.

sudo docker exec-it Customer/bin/bash

root@f945b6723f41:/usr/local/tomcat# CD webapps/

root@f945b6723f41:/usr/local/tomcat/webapps# pwd

/usr/local/tomcat/webapps

root@f945b6723f41:/usr/local/tomcat/webapps# ls

Cumstomermanage ROOT Examples Manager

Cumstomermanage.war Docs Host-manager

root@f945b6723f41:/usr/local/tomcat/webapps#

3. Write the automatic build script file.

#!/bin/bash

#切换目录
cd ~/customermanage_web/

#拉取最新代码
git pull

#生成war包
MVN Package- Dmaven.test.skip=true

sudo docker restart customer

#拷贝war包
sudo docker cp ~/customermanage_web/target/ Cumstomermanage.war customer:/usr/local/tomcat/webapps

#重启tomcat

sudo docker restart customer

Add script execution permissions when finished.

chmod 755 deploy_customer.sh

PS. This place also solves a MVN package compilation problem, MVN packge when prompted [Maven]package Com.sun.image.codec.jpeg does not exist

Oracle has retired from all of Com.sun's bags since jdk7.

Synopsis:the Non-standard Com.sun.image.codec.jpeg Package is retired description:the

Package is added in JDK 1.2 (DEC 1998) as a non-standard way of controlling the loading and saving of JPEG format image f Iles. This package is never part of the platform specification and it has been removed to the Java SE 7 release. The Java Image I/O API is added to the JDK 1.4 release as a standard APIs and eliminated the need for the com.sun.image.co Dec.jpeg package.

To solve this problem, just add it to the Pom file

			<plugin>
				<artifactId>maven-compiler-plugin</artifactId>
				<version>2.5.1</ version>
				<configuration>
					<compilerargument>-xdignore.symbol.file</compilerargument >
                                </configuration>

4. Execute the script, confirm the execution result

./deploy_customer.sh

5. The team member used to feel very convenient, and then came up with a small need to automatically generate daily version of the day, the test the next morning to verify the latest code, the implementation is also very simple, in the crontab to add timed tasks.

Crontab-e


# m H  Dom Mon Dow   command
0 1 * * * */home/git/deploy_customer.sh

The first argument is the minute, the second parameter is the hour, and the latter several * represent running daily.

After the end, after the follow-up if there is time to toss down the Jenkins, to achieve continuous integration.
