Docker??

Martin · 2016-07-31 22:01:08

I really only have one quick question: Is docker.io which I find in repo the same thing as Docker?

Background (since you asked): When back from summer vacation it is time to up-grade my work computer and going for Linux instead of W7 is an option. However, two of the CAE tools I use do not support the Linux flavour on offer. It has been suggested that Docker could be a workaround. I am pondering playing a little with Docker on my home system -- unless strongly adviced not to.

Install it and see? However...

https://docs.docker.com/engine/installa … ux/debian/

^ Purging docker.io is one of the steps. I'd use this to get the latest current 'stable' version, and keep it up-to-date using their instructions...

sudo apt-get update && sudo apt-get upgrade docker-engine

Ninja'd by the speedy hhh.
But here's my input anyway....

= = = = = =
YES, it's the same ...

But not to be confused with "docker" in the repos - which is "System tray for KDE3/GNOME2 docklet applications"

Description: System tray for KDE3/GNOME2 docklet applications
 Docker is a docking application (WindowMaker dock app) which acts as a system tray for any desktop environment,
 allowing you to have a system tray without running the KDE/GNOME panel Docker was designed to work with Openbox
 2, but it should work fine in any window manager.

Description: Linux container runtime
 Docker complements kernel namespacing with a high-level API which operates at the process level. It runs unix
 processes with strong guarantees of isolation and repeatability across servers. 
 
 Docker is a great building block for automating distributed systems: large-scale web deployments, database
 clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc. 
 
 This package contains the daemon and client. Using docker.io on non-amd64 hosts is not supported at this time.
 Please be careful when using it on anything besides amd64. 
 
 Also, note that kernel version 3.8 or above is required for proper operation of the daemon process, and that
 any lower versions may have subtle and/or glaring issues.

  $

So when you get it make sure you:

sudo apt-get install docker.io

Simulated get for both:
alias sget='sudo apt-get install --no-install-recommends --simulate'

Thanks guys, good respons.

I have tried to read up a little on LXC, searching for howtos etc. What I have not found so far is information confirming/showing that I can do the following. Having a box running Linux flavour A I can fool application ABC into believing that this LXC (or Docker or whatever) container is actually the Linux flavour C that ABC needs to install and run properly.

Any leads are appreciated.

I'm also doing some exploration of the LXC (and now LXD) tools. I've found the following blog posts very helpful - https://www.stgraber.org/2013/12/20/lxc … st-series/

Espcially since they're written by the lead dev on the LXC/LXD team.

If you're interested in LXD this post series is good - https://www.stgraber.org/2016/03/11/lxd … eries-012/

*Note* LXD is more of an Ubuntu thing, at least for the moment. But it's built on LXC so it might be fairly simple to bring over to a more direct Debian spin.
