Issue building docker image about my-project

[mhmdahmed167]

Hello,

I have folk your repo and i'm having this issue on building the docker image:

Step 3/5 : COPY ./build/libs/my-app-1.0-SNAPSHOT.jar /usr/app/ COPY failed: file not found in build context or excluded by .dockerignore: stat build/libs/my-app-1.0-SNAPSHOT.jar: file does not exist Error: Command failed: docker build -f Dockerfile -t docker.io/***/myrepo/demo-app:master-27211ac .

Do you have an idea of the missing .jar file ? Thanks.

Got the solution:
If you open the Dockerfile and checkout the components in COPY and ENTRYPOINT, the project name will be "my-app-1.0-SNAPSHOT.jar" just change it to "java-app-1.0-SNAPSHOT.jar"
It should run smoothly after that

solution: open dockerfile and replace
COPY ./build/libs/my-app-1.0-SNAPSHOT.jar /usr/app/
with
COPY ./build/libs/java-app-1.0-SNAPSHOT.jar /usr/app/
and
ENTRYPOINT ["java", "-jar", "my-app-1.0-SNAPSHOT.jar"]
with
ENTRYPOINT["java", "-jar", "java-app-1.0-SNAPSHOT.jar"]

make sure you have a build folder like in the new-ci-workflow branch this folder contains jar files

@mhmdahmed167 your solution works...how did you reached this solution?...where did you check?

[mhmdahmed167]

I basically just used basic debugging when I couldn’t understand the issue after multiple attempts. So I sat down and started back tracking every line in the Dockerfile and verifying it. After that it was just a matter if time before I realized the error that was being made.

@maulanaakbardj and @mhmdahmed167 : The solution works, but a following step fails with the below message;

Error: Unsupported GitHub event - only supports push https://help.github.com/en/articles/events-that-trigger-workflows#push-event-push

Does this mean that we can't build the docker image as part of the pull request? I.e., we can only build the docker image when pushing to main?

UPDATE: In the dockerfile, changing:

uses: mr-smithers-excellent/docker-build-push@v4

to

uses: mr-smithers-excellent/docker-build-push@v6

This resolves the issue
