Docker compose build relative path

creditcard-monk:
 build:
  context: ./creditcard
  dockerfile: Dockerfile
  args:
    JAR_FILE: target/creditcard-1.0.0.jar

Docker compose version 3.0. The jar_file argument is used to copy the jar-file to spring-boot jar under docker container

I get the error failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder347176151/target/creditcard-1.0.0.jar: no such file or directory

i thought the mentioning of context ,will read jar from target folder .but it seems docker-compose is not reading the file from context specified

Please help. Note:- the docker file is simple, built from alpine-java-8 and a copy command to copy jar to container to start spring boot app

version: "3.1"
services:
    creditcard-monk:
     build:
      context: ./
      dockerfile: Dockerfile
      args:
        JAR_FILE: target/creditcard-1.0.0.jar

or

docker build --build-arg JAR_FILE=target/creditcard-1.0.0.jar

both commands worked now. But the second command worked in most cases and never failed.

As the docker is already running inside the folder

Your current code assumes the following path exists:

./creditcard/target/creditcard-1.0.0.jar

The JAR_FILE path will be inside the path you specified for context. Double check what the path should be and update your context and JAR_FILE argument accordingly.
