Cloud Builds Failulre , unable to find logs to see what is going on - google-cloud-dataflow

Question

i am kicking off a dataflow flex template using a cloud build. In my cloud build file i am attempting to do 3 things
build an image
publish it
run a flex template job using that image
this is my yaml file
substitutions:
_IMAGE: my_logic:latest4
_JOB_NAME: 'pipelinerunner'
_TEMP_LOCATION: ''
_REGION: us-central1
_FMPKEY: ''
_PYTHON_VERSION: '3.8'
# checkout this link https://github.com/davidcavazos/python-docs-samples/blob/master/dataflow/gpu-workers/cloudbuild.yaml
steps:
- name: gcr.io/cloud-builders/docker
args:
[ 'build'
, '--build-arg=python_version=$_PYTHON_VERSION'
, '--tag=gcr.io/$PROJECT_ID/$_IMAGE'
, '.'
]
# Push the image to Container Registry.
- name: gcr.io/cloud-builders/docker2
args: [ 'push', 'gcr.io/$PROJECT_ID/$_IMAGE' ]
- name: gcr.io/$PROJECT_ID/$_IMAGE
entrypoint: python
args:
- /dataflow/template/main.py
- --runner=DataflowRunner
- --project=$PROJECT_ID
- --region=$_REGION
- --job_name=$_JOB_NAME
- --temp_location=$_TEMP_LOCATION
- --sdk_container_image=gcr.io/$PROJECT_ID/$_IMAGE
- --disk_size_gb=50
- --year=2018
- --quarter=QTR1
- --fmpkey=$_FMPKEY
- --setup_file=/dataflow/template/setup.py
options:
logging: CLOUD_LOGGING_ONLY
# Use the Compute Engine default service account to launch the job.
serviceAccount: projects/$PROJECT_ID/serviceAccounts/$PROJECT_NUMBER-compute#developer.gserviceaccount.com
And this is the command i am launching
gcloud beta builds submit \
--config run.yaml \
--substitutions _REGION=$REGION \
--substitutions _FMPKEY=$FMPKEY \
--no-source
The error message i am getting is this
Logs are available at [https://console.cloud.google.com/cloud-build/builds/0f5953cc-7802-4e53-b7c4-7e79c6f0d0c7?project=111111111].
ERROR: (gcloud.beta.builds.submit) build 0f5953cc-7802-4e53-b7c4-7e79c6f0d0c7 completed with status "FAILURE
but i cannot access the logs from the URL mentioned above
I cannot see the logs, so i am unable to see what is wrong, but i stongly suspect somethign in my run.yaml is not quite right
Note: before this, i was building the image myself by launching this command
gcloud builds submit --project=$PROJECT_ID --tag $TEMPLATE_IMAGE .
and my run.yaml just contained 1 step, the last one, and everything worked fine
But i am trying to see if i can do everything in the yaml file
Could anyone advise on what might be incorrect? I dont have much experience with yaml files for cloud build
thanks and regards

Answer 1

I guess the pipeline does not work because (in the second step) the container: gcr.io/cloud-builders/docker2 does not exist (check https://gcr.io/cloud-builders/ - there is a docker container, but not a docker2one).
This second step pushes the final container to the registry and, it is a dependence of the third step, which will fail too.
You can build the container and push it to the container registry in just one step:
steps:
- name: 'gcr.io/cloud-builders/docker'
args: ['build', '-t', 'gcr.io/$PROJECT_ID/$IMAGE_NAME', '<path_to_docker-file>']
images: ['gcr.io/$PROJECT_ID/$IMAGE_NAME']

Answer 2

Ok, sorted, the problem was the way i was launching the build command
this is the original
gcloud beta builds submit \
--config run.yaml \
--substitutions _REGION=$REGION \
--substitutions _FMPKEY=$FMPKEY \
--no-source
apparently when i removed the --no-source all worked fine.
I think i copied and pasted the command without really understanding it
