Do you NEED to move to LXD, to begin with?

Mass deployment of similar containers.

See above. LXD is more suitable for automated (re)deployment of likewise
containers.

If all you need is an occasional isolation of an experimental/production
environment, LXC is more than enough.

Re: [lxc-users] dynamic cgroup memory limit

[Tian-Jian Wu]

We are developers of project clondroid (https://github.com/clondroid)
Our android porting lxc tools are at
https://github.com/clondroid/lxc-for-Android-7.1.2.
This command 'lxc config set my-container limits.memory 256MB' , the 'lxc'
command seems be part of LXD project.
If so, I guess it's written in GOLANG.  Wondering if there is a chance to
port LXD to android...

please allow my silly question , how?
I know it's ok to set memory limit in config file and it's set to kernel
later.
But after container started how to change memory limit?  What command?
