将 Docker 部署到 AWS Elastic Beanstalk：无法执行命令 'docker pull maven'

Question

我有一个要部署到 Amazon Web Services 的 Maven 项目 Elastic Beanstalk。我想使用 Docker 文件进行部署。

Docker 文件可以在我的 Windows PC 上本地运行，但部署到 Elastic Beanstalk 时就不行了。我的项目结构如下所示：

~/my-project/
|-- Dockerfile
|-- src
|-- pom.xml

这是我的 Docker 文件：

# Build stage 
# 
FROM maven:3.8.1-jdk-8 AS build
ADD src /tmp/src
ADD pom.xml /tmp/pom.xml
RUN mvn -f /tmp/pom.xml clean package


#
# Package stage
#
FROM openjdk:8
COPY --from=build /tmp/target/my-project-host-0.0.1-SNAPSHOT.jar /usr/local/lib/my-project.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","/usr/local/lib/my-project.jar"]

要在本地使用和执行这个 Docker 文件，我所做的就是运行来自项目根目录的这些命令，然后我的 Springboot 服务器启动并且运行ning:

docker build -t image-my-project .
docker run -d -p 8080:8080 image-my-project

问题来了。为什么在部署到 AWS Elastic Beanstalk.

时会失败

我将详细介绍如何将其部署到 Elastic Beanstalk。

1) navigate to project root (my-project) and run the command:
    a) eb create
    b) this will prompt me with configuring the environment.
2) Set up environment with the following configs:
    a) name of environment: my-project
    a) load balancer type = 'application' (Should this be 'network' instead?)
3) After setting up the configs, the project begins to deploy but it always fails.

如果我下载 eb-engine.log 文件，则会收到错误消息，指出 docker 无法拉取 Maven。这是日志文件的那一部分：

有人知道发生了什么事吗？为什么我的 Docker 文件在本地工作，但不会部署到 AWS Elastic Beanstalk？

Answer 1

我想通了所以我会为未来的读者留下答案。结果是 AWS 不允许您在 Docker 中使用 AS 关键字。所以我更改了文件：

# Build stage 
# 
FROM maven:3.8.1-jdk-8 AS build
ADD src /tmp/src
ADD pom.xml /tmp/pom.xml
RUN mvn -f /tmp/pom.xml clean package


#
# Package stage
#
FROM openjdk:8
COPY --from=build /tmp/target/my-project-host-0.0.1-SNAPSHOT.jar /usr/local/lib/my-project.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","/usr/local/lib/my-project.jar"]

为此：

# Build stage 
# 
FROM maven:3.8.1-jdk-8 
ADD src /tmp/src
ADD pom.xml /tmp/pom.xml
RUN mvn -f /tmp/pom.xml clean package


#
# Package stage
#
FROM openjdk:8
COPY --from=0 /tmp/target/my-project-host-0.0.1-SNAPSHOT.jar /usr/local/lib/my-project.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","/usr/local/lib/my-project.jar"]
