Installation of ZeroTier VPN on Docker Instance

[longshot338]

Objective:

• Create self-hosted cloud network with services to enhance the quality of life for my wife.
• Want to have applications individually addressed in the VPN to rule out TCP/IP issues between applications.
• This would also ease administration of the application stack as the stack builds

Resources:

• Windows host OS running Hyper-v Virtual Ubuntu machines (for portability will be migrating to an actual server soon)
• Ubuntu machine is running Docker with Grocy and BarcodeBuddy
• Docker container is installed with ZeroTier VPN and is servicing both applications with the same IP address on the vpn

Issue:

• Once inside the BarcodeBuddy docker instance several crucial commands for the software installation are missing (apt, dkpg, and more)

• How would I install Zerotier VPN on the BarcodeBuddy docker machine?
