Docker: invalid reference format

General

Error: docker: invalid reference format.
HOST: Windows 10
Scripting language: Python
docker command used:
runc_vvc_docker_container = ‘docker run -d --name ’ + container_name + ’ --rm -v ’ + mount_dir + ‘:/shared/vvc’ + ’ --privileged -p 2210:2210 -p 8010:8010 ’ + image_to_run + ’ tail -f /dev/null’
print(runc_vvc_docker_container)

output = os.system(runc_vvc_docker_container)
print(output)

Backgroud:
I want to run the container in back-end, and run vvc custom configurations in later stage.(i.e vvc -u -c “custom_config.cfg”)

Strange behavior:
print(runc_vvc_docker_container) results in → docker run -d --name SWQT --rm -v D:/Work/Blackhole/Azure_Reference_Repo/VRTE_FCs/str-psx-emmc-utils/_qt_project:/shared/vvc --privileged -p 2210:2210 -p 8010:8010 xyz.com/ela7si/vvc:imagename tail -f /dev/null

  1. Above command when run on the windows command prompt manually - it runs with no error.
  2. But when run through python script, results in docker: invalid reference format.

# Working -
subprocess.call('docker run -it --name ’ + container_name + ’ --rm -v ’ + mount_dir + ':/shared/vvc ’ + '–privileged -p 2210:2210 -p 8010:8010 ’ + image_to_run, shell=True)

# Not Working - and also throws Error : docker: invalid reference format.
subprocess.call('docker run -it --name ’ + container_name + ’ --rm -v ’ + mount_dir + ':/shared/vvc ’ + ‘–privileged -p 2210:2210 -p 8010:8010 ’ + image_to_run + ’ tail -f /dev/null’, shell=True)

# Working - runc_vvc_docker_container = 'docker run -d --name ’ + container_name + ’ --rm -v ’ + mount_dir + ‘:/shared/vvc’ + ’ --privileged -p 2210:2210 -p 8010:8010 ’ + image_to_run
os.system(runc_vvc_docker_container)

# Not Working - runc_vvc_docker_container = 'docker run -d --name ’ + container_name + ’ --rm -v ’ + mount_dir + ‘:/shared/vvc’ + ’ --privileged -p 2210:2210 -p 8010:8010 ’ + image_to_run + ’ tail -f /dev/null’
os.system(runc_vvc_docker_container)

Options tried:

  1. shared directory in all small letters
  2. both windows and linux path separator(‘/’ and ‘') and also with double slahses (’//')
  3. ried with and without interactive (-it) mode

output = os.system(runc_vvc_docker_container)
print(output) → results in 125 error code.
