I have already posted this as an issue on Github at https://github.com/snakemake/snakemake/issues/279 but haven't got any response yet. I hope to find help here.
Version
I am using the following versions on our HPC cluster: Snakemake c5.4.4 singularity version 3.5.3
Minimal example
singularity: "docker://bash"
rule test:
shell: "echo test"
Describe the bug
snakemake --use-singularity --debug
returns this message:
Building DAG of jobs...
Pulling singularity image docker://bash.
Using shell: /bin/bash
Provided cores: 1
Rules claiming more threads will be scaled down.
Job counts:
count jobs
1 test
1

Error in rule test:

RuleException:

Shutting down, this might take some time.
Exiting because a job execution failed. Look above for error message

Apparently, snakemake runs singularity with default values for --home and --bind. These were disallowed by the administrator, however.
Executing
singularity exec --home /data/nanopore/test --bind /opt/snakemake/v5.4.4/lib/python3.5/site-packages/snakemake-5.4.4-py3.5.egg:/mnt/snakemake /data/nanopore/test/.snakemake/singularity/36b22e49e8a03fd08160e9345dd1034e.simg bash -c 'set -euo pipefail;'
returns:
FATAL: container creation failed: not mounting user requested home: user bind control is disallowed
Additional context
Is there a way to disable the Singularity default parameter setting in snakemake? Inside the singularity container the /data
directory is still writeable and readable anyway.
Thanks a lot
