Ubuntu Core and Docker like networking

uz flag

Does Ubuntu Core and Snaps (containers) allow for the flexibility that Docker networking allows, such as:

  • default docker bridge
  • user defined bridge
  • deploying containers to host networking
  • MACVLANs (MAC address virtual local area networks)/ switch like
  • IPVLANs / router like
  • overlay networks
  • none networks

A very good example and the ease of use & flexibility of adding and removing containers as part of networks is shown by example by NetworkChuck: https://www.youtube.com/watch?v=bKFMS5C4CG0

Otherwise, if I install Docker Snap (sudo snap install docker) would all my Docker containers be deployed within this one Docker Snap allowing for all the networking customization to function?

Snaps are NOT a flavor of containerization.

Snaps are merely a form of software packaging that include AppArmor rule-based sandboxing and other fancy designs for robustness, security, and safety. They generally do not use cgroups (except for snaps that include containers, of course).


"[I]f I install Docker Snap (sudo snap install docker) would all my Docker containers be deployed within this one Docker Snap allowing for all the networking customization to function?"

Close. The docker snap is the docker hypervisor. Your containers will be installed by (not in) that hypervisor. Yes, your custom networking will be implemented by the hypervisor.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
