Deploying Docker to AWS Elastic Beanstalk: failed to execute command 'docker pull maven'-CodePudding

I have a maven project that I am trying to deploy to Amazon Web Services' Elastic Beanstalk. I want to deploy using a Docker file.

The Docker file works locally on my Windows PC, but not when deployed to Elastic Beanstalk. The structure of my project looks like this:

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

This is my Docker file:

# 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"]

To use and execute this Docker file locally, all I do is run these commands from project root and then my Springboot server is up and running:

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

Now comes the problem. Why does this fail when deployed to AWS Elastic Beanstalk.

I will give a walkthrough of exactly how I am deploying it to 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.

If I download the eb-engine.log file, then I get errors stating that the docker failed to pull Maven. Here is that part of the log file:

Anyone have any idea what is going on? Why does my Docker file work locally, but won't deploy to AWS Elastic Beanstalk?

CodePudding user response：

I figured it out so I will leave an answer for future readers. Turns out AWS doesn't allow you to use the AS keyword in Docker. So I changed the file from:

# 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"]

To this:

# 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"]
