LXC

LXC is an operating system-level virtualization method for running multiple isolated Linux systems (containers) on a single control host. LXC provides operating system-level virtualization by providing a virtual environment that has its own process and network space. LXC relies on the Linux kernel cgroups functionality. LXC is similar to other OS-level virtualization technologies on Linux such as OpenVZ and Linux-VServer, as well as those on other operating systems such as FreeBSD.

My LXD host is running Ubuntu 17.04.  I created a bridged interface and set that interface as the default network for all LXD containers...  This results in my containers being on my LAN..  This works just fine, however, I'm now trying to run Docker inside a LXD container.  My goal is to place all Docker container on the same LAN.  How can I create a Docker network to be on the same LAN while nested on a LXD container?

Can someone describe in detail how to install Minio on QNAP's ContainerStation?  I have installed ContainerStation, clicked on "Create Container", chosen minio/minio.  I have tried various settings on "Advanced Settings", but when I run the Docker Container, it tries to start then stops on its own.

I have one docker server called PRIVREG with a private registry on it

I can push and pull to that registry  from the docker  engine on the same box

if I goto another box named DOCKER901I can CURL a list of tags in the remote server with the command

curl http://privreg:5000/v2/ssmith/mybusybox/tags/list at it works fine as exected and returns a list of tags in that repo

but if I attempt to pull one with docker pull http://privreg:5000/v2/ssmith/mybusybox:1.0

i get  the error    Invalid repository name (ex: "registry.domain.tld/myrepos")


this is the same URL why does it error like this?
??

thanks!

I am very familiar with VMs and virtulization. However, I have only heard about Docker (never used it) and would like to grasp the idea and concept.

I understand Docker creates 1 or more individual "worlds" similar to VMs, but uses a lot less resources?
Can you explain more about docker as well as how it is difference from VMs (vmware, Xen, KVM).

Hello, I can't found an control panel for docker, for: deploy, create, remove and assign ports to containers.

Anyone can suggest a free or paid one?

When I try to run Docker, I get a problem.  The message is right: a URL is broken.  I know that ubuntu.com is not completely down.  I tested it.  But the URLs in the error log don't work (like the error says).  How do I get Docker to use correct working URLs?  What are the working URLs?

Here is what I try to run:

docker build -t some-content-nginx .
