Hello. As part of a master's thesis, I would like to perform some experiments in GCE cloud via CBTOOL. My first aim is to run nullworkload appliction with the usage of nested containers. I took the following steps:

...

[VM_DEFAULTS : GCE_CLOUDCONFIG]
NEST_CONTAINERS_ENABLED = $True

[VM_TEMPLATES : GCE_CLOUDCONFIG]
NEST_CONTAINERS_BASE_IMAGE = size:NA, imageids:1, imageid1:my-ubuntu-1804-lts, cloudinit_packages:openvpn;bc;jq;docker.io;python;redis-server;ntp;redis-tools

Unfortunately, when I'm trying to attach the nullworkload application instance to my experiment by the command:

  • aiattach nullworkload

I'm getting the following errors:

marcin@orchestrator:~/cbtool$ ./cb --hard_reset
