GITLIbCICD流水线搭建

news 2025/5/23 9:14:02

1，搭建gitLIb服务器，创建gitlibRunner 并且注册，

2. 写dockerfile 包块java程序运行的环境，jdk，参数等，

2.1ai生成版本，

	# 基础镜像（JDK 17）FROM eclipse-temurin:17-jdk-alpine# 设置工作目录WORKDIR /app# 复制Maven配置（可选）COPY .m2/settings.xml /root/.m2/# 复制项目文件COPY pom.xml .COPY src/ src/# 构建应用（跳过测试）RUN mvn -B -DskipTests clean package# 使用JRE运行时镜像FROM eclipse-temurin:17-jre-alpine# 复制构建好的应用COPY target/*.jar app.jar# 配置端口EXPOSE 8080# 定义启动命令ENTRYPOINT ["java","-jar","app.jar"]

2.2实战版本这里还不完全，实战中应该dockerfile中还应该写日志挂载等目录同步到服务器上，

# 使用更小的基础镜像
FROM openjdk:17-jdkWORKDIR /app# 创建自定义java.security（保持原有安全配置）
RUN echo "jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \\" > /app/java.security && \echo "    EC keySize < 224, 3DES_EDE_CBC, anon, NULL" >> /app/java.security# 直接复制CI生成的JAR文件（需确保文件路径正确）
COPY *.jar app.jar# 环境变量配置（保持原有）
ENV JDK_TLS_CLIENT_PROTOCOLS="TLSv1,TLSv1.1,TLSv1.2,TLSv1.3"
ENV HTTPS_PROTOCOLS="TLSv1,TLSv1.1,TLSv1.2,TLSv1.3"
EXPOSE 48080# 合并JAVA_OPTS定义（更清晰）
ENV JAVA_OPTS="-Xms512m -Xmx1024m \-Djdk.tls.client.protocols=TLSv1,TLSv1.1,TLSv1.2,TLSv1.3 \-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2,TLSv1.3 \-Djava.security.properties=/app/java.security"# 使用exec格式启动（保持原有最佳实践）
ENTRYPOINT ["sh", "-c", "exec java $JAVA_OPTS -jar /app/app.jar"]

3.编写.gitlib-ci.yml文件放置在根目录下，

3.1ai生成版本，

3.2实战使用版本，

3.4 对应的一些私钥应该配置在 gitlib的变量当中，

如 sshkey私钥等。
