How can I specify Argo workflow multiple output artifacts to a single directory? - argo-workflows

Question

I'm using Argo Workflow, and want to produce 2 separate artifacts. Defining the output artifacts as below, it tells me path '/tmp' already mounted in inputs.artifacts.txt. How can I mount produce 2 separate artifacts to a single directory(in this case, /tmp)?
outputs:
artifacts:
- name: txt
path: /tmp
s3:
endpoint: s3.amazonaws.com
bucket: <My Bucket>
key: test.txt.tgz
accessKeySecret:
name: vault-data
key: s3_access_key-0
secretKeySecret:
name: vault-data
key: s3_secret_key-0
- name: total-file-count
path: /tmp
s3:
endpoint: s3.amazonaws.com
bucket: <My Bucket>
key: total-file-count.tgz
accessKeySecret:
name: vault-data
key: s3_access_key-0
secretKeySecret:
name: vault-data
key: s3_secret_key-0

Answer 1

path refers to the full path of the artifact to be written to S3 (not just to the directory in which the file is found).
To write both artifacts to S3, use the full path of the source files. Assuming the filenames match the key names, this should work:
outputs:
artifacts:
- name: txt
path: /tmp/test.txt.tgz
s3:
endpoint: s3.amazonaws.com
bucket: <My Bucket>
key: test.txt.tgz
accessKeySecret:
name: vault-data
key: s3_access_key-0
secretKeySecret:
name: vault-data
key: s3_secret_key-0
- name: total-file-count
path: /tmp/total-file-count.tgz
s3:
endpoint: s3.amazonaws.com
bucket: <My Bucket>
key: total-file-count.tgz
accessKeySecret:
name: vault-data
key: s3_access_key-0
secretKeySecret:
name: vault-data
key: s3_secret_key-0
