Concourse put task into docker-image resource. Build_args are not passed to Dockerfile-CodePudding

I have a case when the following Concourse pipeline build_args are not used/passed to docker build phase. The pipeline looks like below one:

 name: project
  type: git
  check_every: 1m
  source:
    uri: ((project-url))
    branch: ((project-branch))
    private_key: ((github-private-key))
    paths: [ ((context))/* ]

- name: registry
  type: docker-image
  source:
    username: ((art_user))
    password: ((art_token))
    repository: docker.artifactory......

... ...

jobs:

- name: publish
  serial: true
  plan:
  - in_parallel:
    - get: project
     ... ...
  - put: build
    resource: registry
    params:
      build: project/((context))
      build_args:
        a_user: ((art_user))
        a_token: ((art_token))
        testArg: "testing"

Dockerfile in the context directory has the following content. I remove any specifics from it.

FROM docker.artifactor.../debian:buster

#####################

ARG a_user
ARG a_token
ARG testArg
RUN echo "a_user: $a_user"
RUN echo "a_token: $a_token"
RUN echo "testArg: $testArg"
RUN env

Issue is these variables have empty values during build time. Below is a sample run:

Could you please help here.

CodePudding user response：

The pipeline you pasted has been edited down too heavily for me to put a finger on exactly what's wrong, but one thing I notice is that the image resource is named 'registry' but the put refers to the build resource (?!). The registry is referenced by a resource param,
