CoreOS: Future of Servers | LAS 315

CoreOS: Future of Servers | LAS 315

The CTO of CoreOS joins us to go into detail about how CoreOS deploys applications in Docker Containers, allows for automatic server updates, and might just finally fix security on the web.

Plus: We’ll wrap up the TrueCrypt upset, and discuss our prefered Linux TrueCrypt replacements, a quick look at Mint 17…


All this week on, The Linux Action Show!

Google Cloud Platform Blog: Official CoreOS images are now available on Google Compute Engine

CoreOS integrates easily with Google load balancers and replica pools to easily scale your applications across regions and zones. Using replica groups with CoreOS is easy; configure the project-level metadata to include a discovery URL and add as many machines as you need. CoreOS will automatically cluster new machines and fleet will begin utilizing them. If a single machine requires more specific configuration, additional cloud-config parameters can be specified during boot.

The Companies That Support Linux: CoreOS |

On May 19, CoreOS joined the Linux Foundation as a corporate member


  • Run Services with Docker

  • Service Discovery with etcd

  • Cluster Management with fleet

CoreOS Interview:

  • Q: I would really like to hear about the motivation behind that project (maybe a little story how and why it was started).

  • Q: I’ve read “based on ChromeOS” quite a bit. We assume that means its a fork, could you give us the details?

  • Q: How Does CoreOS differ from a traditional “Linux distro”?

  • Q: systemd in CoreOS? How critical is it, and can you give us some examples?

  • Example: Fleet presents the cluster as a distributed init system by aggregating systemd running on each machine.

  • Q: Can you go into more detail about how applications are deployed in Docker?

  • Ex: I want to install nginx, would that process be similar to installing a package via apt, but the software is deployed inside a Docker Container?

  • Q: Can you talk about etcd is used for distributed config managment?

  • Q: If a node fails, how does another node pick up the work if the data is stored in a container? Is central shared storage an important component to a full CoreOS deployment?

  • Q: It seems likely that the web would be a lot safer if we all used CoreOS. Do you personally believe that’s true? And why?

  • Q: You recently wrote about btrfs features that could benefit servers, and specifically Docker containers. Could you talk a bit about that?

    • Q: MANY More! Catch this week’s episode for answers and more questions!

Desktop App Pick

Gnome Encfs Manager

The Gnome Encfs Manager (or short GEncfsM) is an easy to use manager and mounter for encfs stashes featuring per-stash configuration, Gnome Keyring support, a tray menu inspired by Cryptkeeper and lots of unique features. Whether you want to let it do things as simple as mounting a stash at startup, which is often used in conjunction with cloud-synced folders on services like Dropbox & Co., or whether you want to let it automatically mount and unmount your stashes on removeable drives such as USB-disks, SD-cards or even network-resources, GEncfsM is designed to do all the work for you.

TrueCrypt Must Not Die – organizing a future

This is not a fork (yet), we just coordinate, a fork will probably have a new name. Combining efforts is most important for now.

  • First priority: Making the product available again.
  • Second priority: finding interested and capable persons volunteering to help. Identify and solve legal issues. Identify Security Threats.
  • Additionally: we will wait for the result of the Open Crypto Audit
  • Third priority: Fork the project and solve security threats. Found a support association for continued development.

4000+ Downloads in the first 24 hours: There is still demand for a product like TrueCrypt!

The TrueCrypt project has shut down, and we\’ll run down what we think is the most likely answer to this sudden mystery is.

#TrueCrypt users on Arch and Gentoo your #TrueCrypt has not been updated yet. Keep an eye out

Linux Mint 17 Released!


Linux Mint 17 is a long term support release which will be supported until 2019. It comes with updated software and brings refinements and many new features to make your desktop even more comfortable to use.


The Update Manager was hugely improved.

It shows more information, it looks better, it feels faster, and it gets less in your way. It no longer needs to reload itself in root mode when you click on it. It no longer checks for an Internet connection or waits for the network manager and it no longer locks the APT cache at session startup.

The UI was improved, the icons were modified a bit and the changelog retrieval is now much faster and more reliable.

A new \”type\” column was added to differentiate between traditional updates, security updates, backports and romeo updates.

Security updates can now bypass safety levels and two new options were added for you to decide if they should always be visible and if they should be selected. By default these options are respectively set to True and to False.

Linus Torvalds Reads Mean Tweets

Taking a page from Jimmy Kimmel\’s Mean Tweets series, The Linux Foundation asked Linux creator Linus Torvalds to read some of the community\’s more colorful tweets. Of course, Linus adds his very own commentary.
