Is docker unsecure yet in lxd version 3 ?
I do not understand what you are trying to say.
I mean, is it secure to run docker in lxd or similar to lxc I can’t do this in a secure way.
This is a rule that docker can not be launched in the container in a secure way?
I just did the following in a Ubuntu 18.04.1 LXD container (LXD 3.7).
ubuntu@docker:~$ lsb_release -a No LSB modules are available.

This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/ ubuntu@docker:~$
In terms of security, I used the
security.nesting flag which is OK.
I did not have to use the
