I do have the following "shared.gitlab-ci.yml"

variables:
  GIT_SUBMODULE_STRATEGY: recursive
  DOCKERFILE_BUILD: docker/build/Dockerfile
  DOCKERFILE_TEST: docker/test/Dockerfile
  DOCKERFILE_ANALYZE: docker/analyze/Dockerfile
  BUILD_NAME: $CI_PROJECT_PATH_SLUG:$CI_COMMIT_REF_NAME-$CI_COMMIT_SHORT_SHA
  PREPARE_SCRIPT: ""
  BUILD_ARGS: ""

stages:
- build
- test
- analyze

before_script:
  - echo "Project Details:"
  - echo $CI_PROJECT_PATH_SLUG
  - echo $CI_COMMIT_REF_NAME
  - echo $CI_COMMIT_SHORT_SHA
  - echo "Build Variables:"
  - echo $BUILD_NAME
  - echo $DOCKERFILE_BUILD
  - echo $DOCKERFILE_TEST
  - echo $DOCKERFILE_ANALYZE
  - echo "Directory:"
  - ls -la
  - echo "Registry info:"
  - echo $CI_REGISTRY
  - echo $CI_REGISTRY_NAME
  - echo $CI_REGISTRY_USER
  - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
  - docker info

docker-build:
  image: docker:latest
  stage: build
  services:
    - docker:dind
  script:
    - docker build \
      --rm \
      --build-arg BRANCH_NAME=$CI_COMMIT_REF_NAME \
      --build-arg BUILD_ARGS=$BUILD_ARGS \
      -t $BUILD_NAME \
      $DOCKERFILE_BUILD
    - docker push $BUILD_NAME

Which is will be used/included in another repositories "gitlab-ci.yml" like :

include:
  - project: my-group/shared-pipeline
    ref: master
    file: shared.gitlab-ci.yml

The Dockerfile is also in this repository /docker/build/Dockerfile:

FROM unityci/editor:windows-2020.1.16f1-base-0.17.2 as unity 
ARG BRANCH_NAME
ARG BUILD_ARGS

CMD echo "Hello world! This is my first Docker image. Branch: $BRANCH_NAME" 

Somehow when I run the "gitlab" pipeline I'll get the following output:

Fetching changes...

"docker build" requires exactly 1 argument.
See 'docker build --help'.
Usage:  docker build [OPTIONS] PATH | URL | -

ERROR: Job failed: exit code 1

I always get: "docker build" requires exactly 1 argument.

I also tried for example:

- docker build --file="$DOCKERFILE_BUILD" 
- docker push $BUILD_NAME

OR

- docker build -f $DOCKERFILE_BUILD
- docker push $BUILD_NAME

The result always stays the same.

I think that you forgot '.'(dot)

docker build -f $DOCKERFILE_BUILD . 

(In my case) Even with this command, I got the error ...

  • you are right. I forgot
