Nextflow with Docker does not find local image

[alex-d13]

Bug report

I am using Nextflow with Docker and Slurm. I created a local Docker image called omnideconv_benchmark which I wanted to use to run my NF script. However, it seems like Nextflow does not find my image:

Command error:
  Unable to find image 'omnideconv_benchmark:latest' locally
  docker: Error response from daemon: pull access denied for omnideconv_benchmark, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
  See 'docker run --help'.

Expected behavior and actual behavior

I would expect that the local image can be found and used by nextflow. Instead it is not found and the error above appears.

Steps to reproduce the problem

Program output

nextflow.log

Environment

• Nextflow version: [22.10.1]
• Java version: [11.0.17]
• Operating system: [Ubuntu 20.04.5]
• Bash version: 5.0.17

Additional context

I am starting Nextflow in a slurm spool directory. Maybe that could be the reason, that it does not find images out of its scope?

The error message says repository does not exist or may require 'docker login'

This means you need to authenticate the docker client in the slurm nodes when the job running. Ask your sysadmin for details

Hi,

Yes I noticed that as well, but when I do use docker login prior to running nextflow successfully, i still get the same error.
(Btw: i am working on a small cluster on my own, so there is no sysadmin apart from myself :D)

Could it be a solution to upload my image to docker hub and then nextflow will try to pull it from there?

I fixed this issue by uploading my image to Dockerhub and then nextflow will pull it from there.
