Set src file path into Dockerfile

After compilation .jar file in:

/var/lib/jenkins/workspace/PROD__Backend-Build-Deploy/target/laplacelab-0.0.1-SNAPSHOT.jar

But old Dockerfile was run just from a folder with .jar and Dockerfile.

FROM adoptopenjdk/openjdk11

VOLUME /tmp
ADD laplacelab-0.0.1-SNAPSHOT.jar laplacelab-0.0.1-SNAPSHOT.jar
RUN sh -c 'touch /laplacelab-0.0.1-SNAPSHOT.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/laplacelab-0.0.1-SNAPSHOT.jar"]

Where I should change the path for new dir? Only in ENTRYPOINT line or ADD need to change too? What should it be like to be for the new structure?

Docker can't access files outside of the Docker build context, so you will need to either move the file or specify the context in your build command, e.g.:

docker build -t foo:latest /var/lib/jenkins/workspace/PROD__Backend-Build-Deploy/target/

If you do not have your Dockerfile in the same directory as your build context, you will need to specify its location using -f, like this:

docker build -t foo:latest -f ./Dockerfile /var/lib/jenkins/workspace/PROD__Backend-Build-Deploy/target/

In Compose it can look something like this:

build:
  context: /var/lib/jenkins/workspace/PROD__Backend-Build-Deploy/target/
  dockerfile: ./Dockerfile
