I solved the problem.
The additional capability parameters are host configs and have to be added
to the "extra_host_config as list:
c.DockerSpawner.extra_host_config = {
'network_mode': network_name,
'mem_limit': '24G',
'security_opt': ['apparmor:unconfined'],
'cap_add': ['SYS_ADMIN','DAC_READ_SEARCH'],
}
In addition it is necessary to specify another parameter for linux
security: "security_opt"
With this configuration it is possible to use mount in jupyter notebook
containers.
