如何将SpringBoot (.war)应用部署到云运行中？

Question

我有一个SpringBoot项目，我部署到了Google App Engine上。它工作得很好。该网站的访问量不是很高。但它的账单成本却在上升。

因此，我决定将我的SpringBoot项目转移到"Cloud Run“。

我已尝试使用以下链接https://cloud.google.com/run/docs/quickstarts/build-and-deploy/java

但在上面的教程中，他们详细介绍了jar文件。

本项目中使用的是Jave 8，SpringBoot 2.3.0版本。

应用程序引擎的pom.xml

<plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>appengine-maven-plugin</artifactId>
                <version>2.2.0</version>
                <configuration>
                    <projectId>MY-SPRING-BOOT-APP</projectId>
                    <version>1</version>
                    <ssl-enabled>true</ssl-enabled>
                </configuration>
            </plugin>

DockerFile

# Use the official maven/Java 8 image to create a build artifact.
# https://hub.docker.com/_/maven
FROM maven:3.8-jdk-11 as builder

# Copy local code to the container image.
WORKDIR /app
COPY pom.xml .
COPY src ./src

# Build a release artifact.
RUN mvn package -DskipTests

# Use AdoptOpenJDK for base image.
# It's important to use OpenJDK 8u191 or above that has container support enabled.
# https://hub.docker.com/r/adoptopenjdk/openjdk8
# https://docs.docker.com/develop/develop-images/multistage-build/#use-multi-stage-builds
FROM adoptopenjdk/openjdk11:alpine-slim

# Copy the jar to the production image from the builder stage.
COPY --from=builder /app/target/myapp.war /target/myapp.war

# Run the web service on container startup.
CMD ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/target/myapp.war"]
#CMD ["catalina.sh","run"]

有什么想法吗？

最后，我成功地将我的springboot应用程序部署到cloud run，而无需更改包类型。
