Docker, Mesosphere and Network Attached Storage

Watch this Mesosphere Demo in order to explain how wonderful mesosphere could be for I.T. Infrastructures everywhere. Network attached storage plays a key role in Docker/Mesosphere which explains why Adequatech recommends one at the end of this blog entry. Learn more about Mesosphere here. The following demonstrates the usefulness of docker and mesosphere.
    This first part installs golang followed by docker:
  • hg clone -u release
  • cd go/src/
  • ./all.bash
  • export GOROOT=/home/loongson/go
  • export GOPATH=/home/loongson/Code/go
  • export PATH=$PATH:$GOPATH/bin:$GOROOT/bin
  • go get

    Now install docker:
  • apt-get install lxc
  • gpasswd -a loongson docker
  • service docker restart
  • apt-get install vagrant virtualbox has Debian Sid GNU/Linux running. Now let's do something very cool. Let's run 3 other GNU/Linux flavors of linux running within their own containers while Debian is still running using all current ram and hard-drive resources the original Debian Sid has to offer.
  • docker login
  • docker search debian
  • docker run -i -t centos:latest /bin/bash
  • docker run -i -t ubuntu /bin/bash
  • docker run -i -t yijun/kali-open-university /bin/bash
  • docker images

    mesosphere doesn't directly install on debian sid. No problem, let's resort to installing it within a docker wheezy image. The label "debian:latest" points to the latest wheezy with updates.
  • docker run -i -t debian:latest /bin/bash
  • apt-get update
  • apt-get install aptitude
  • sync
  • sync
  • apt-key adv --keyserver --recv E56151BF
  • DISTRO=$(lsb_release -is | tr '[:upper:]' '[:lower:]')
  • CODENAME=$(lsb_release -cs)
  • echo "deb${DISTRO} ${CODENAME} main" | tee /etc/apt/sources.list.d/mesosphere.list
  • apt-get -y update
  • apt-get -y install mesos marathon

    This part is very important. It takes the debian image and saves all the extra stuff we installed in it and labels it as a committed docker image. After this commit we will always use this instead.
  • ctrl-p ctrl-q
  • docker commit 01b348336969 debian-wheezy-with-mesosphere

    Start the newly committed image. The following command doesn't expose the ports to the outside internet. The fix for that follows later with another switch to the docker run command called "--net host".
  • docker run -i -t debian-wheezy-with-mesosphere /bin/bash

    Start all the mesosphere stuff
  • service zookeeper restart
  • service mesos-master start
  • service mesos-slave start
  • service marathon start

    This shows how to kill that running image
  • docker ps
  • Notice the Container id.
  • docker kill 01b348336969

    This works without fail exposing everything as if it were the host:
  • docker run --net host -i -t debian-wheezy-with-mesosphere /bin/bash
  • service zookeeper restart
  • service mesos-master start
  • service mesos-slave start
  • service marathon start
Now checkout the Mesos console in your browser on port 5050: http://localhost:5050
Now checkout the Marathon console in your browser on port 8080: http://localhost:8080
It's best to configure the firewall within this Debian Wheezy Mesosphere image before exposing it with the "--net" switch. Here is another docker example opening up ports and making data from another directory accessible to this particular image: docker run -i -p 22 -p 8000:80 -m /data:/data -t foo/live /bin/bash
In order to tap into the real power of docker and mesosphere, you will need network attached storage(NAS). As starter gear, highly recommends the WD My Cloud EX4 with two Gigabit Ethernet ports and two power ports. You can use two power adapters to guard against the case of one of them failing or being pulled out by accident(AKA power redundancy). The server works with just one network port, but by having two, it offers more options for load-balancing and redundancy. Once an NAS is integrated into docker and mesosphere, you may do anything you view in the mesosphere demo, but adequatech would like to highlight the most important features: scale or migrate applications. Check out this NAS comparison and what criteria they used to evaluate NAS device performance. They also show the commands they use to connect the cloud ex4 using nfs/cifs:
Let us be clear NFS is faster than CIFS; docker and linux containers compensate for any security concern within nfs/cifs, but keep in mind adequatech recommends to make the cloud ex4 accessible NOT to the outside world, not to entire servers, but only to specific tasks in specific docker/linux containers on a separated LAN(ENCLAVE).

Applied Micro's X-C1 ARM 64-Bit OCTA-CORE Dev Kit

You can now buy Applied Micro's X-C1 ARM 64-bit OCTA-CORE Dev Kit shipping now. Developer Promo price from APM is 900$US, but then goes back up to 1500$US. That said, this kit would be the base for an excellent GNU/Linux desktop computer. 16GB RAM with SATA(hard-disk) and USB 2.0 PORTS(why not USB 3.0?). It can be extended with an external GPU(Graphics Processing Unit) card which puts it in the same category of capabilities as IBM-PC Compatible Desktops, fan noise and all. With respect to noise, it has a power supply with a fan and the SOC itself has a fan also. If you get the GPU, that will also include a fan. This means perhaps you save on electricity, but the noise level increases to the same as AMD/Intel-based products. Perhaps ARM products have an electricity cost advantage at this point with 35% electricity savings, but be prepared to experience incompatibility with existing IBM-PC peripheral printers and scanners. Fedora and Ubuntu GNU/Linux are available now for it. HIGHLY-RECOMMENDED, but 200$ more expensive than comparable Intel/AMD products. Once the developer promo is over, it would be recommended to purchase Intel/AMD for the same capabilities at the most competitive price without taking a risk of peripheral incompatiblities.

Firefly-RK3288 Development Board Runs Debian GNU/Linux

Emailed Firefly a few questions and here are their answers: "Mr. Huang Qiyong is VP of the company. We have years of development experience with Rockchip Soc, dating from the ancient MP3 era. The Firefly development board is powerful. Click here for the Firefly-RK3288 Spec. The price tag of our Firefly-RK3288 development board is USD 129 (without shipping). The performance is good. We have good service support and quick response. Our product has undertaken long time test. It is our first step into the open source world. We have passion and energy. Our team has full support from company and Rockchip (We have good relation with RK, and is one of the best design houses.) This is our first step into open source world. We are still learning. We're open ears to your suggestions." Why did you decide to support Lubuntu with LXDE Desktop instead of GNOME/KDE? Does LXDE support the most popular applications that most users would want? Libreoffice, evince(pdf reader), thunderbird, firefox? "The firmware file size is the main consideration. We try hard to cut down the desktop to under 1 GiB for easy distribution. The office apps can be easily installed by apt-get, and they run fine." Will you provide a repository for ubuntu packages built specifically for your device? "We can if it is necessary. Currently, we just use the Ubuntu official repository." I noticed there is no SATA interface to your dev board out-of-the-box. Are there plans to facilitate a rapid communication with a regular hard-drive? Does the USB 3.0 interface provide equivalent performance to SATA for using it as the main storage and operating system device? "RK3288 does not have SATA interface, nor the USB 3.0 interface. We suggest that using nfs (Network File System) or samba, sshfs, etc to mount the storage over the ethernet (Yes, the board has giga ethernet), which will save the budget and keep data safe." I would have honestly preferred GNOME Desktop because I really don't want to adjust to other applications. "In LXDE, the applications written with GTK or QT run equally fine. We'll have a demo of Gnome desktop once it is worked out."
If you buy this board, you will need some kind of storage drive on your local internet. I have no hesitation recommending this board considering their open-source position and prompt response to my emails. Their web site is clear and has documentation for installing GNU/Linux from downloadable images from their website.
UPDATE 15 December 2014: Firefly RK3288 Quad-Core Development Board with twice as much RAM is now shipping. This board has 4GB DDR3 RAM with 32GB eMMC. You can buy it here for US $212.37 which includes shipping.

Travelling to Northern China? Checkout Changchun Landmarks

Four-day Tour in Changchun(长春) and Xianghai(xiànghǎiguójiāzìránbǎohùqū向海国家自然保护区)) is an understatement as to what wonderful experiences you can have in the Changchun region: Northeast Errenzhuan东北二人转, Jingyuetan National Forest Park (jìngyuètánguójiāsēnlíngōngyuán净月潭国家森林公园), Chagan Lake(Chágànhú查干湖/Shèngshuǐhú聖水湖), Miaoyin Temple, ChangBai Mountain(Chǎngbáishān长白山) and Heaven Lake(Tiānhú天湖). The food there is amazing. You can find restaurants serving memorable, fantastic foods from North Korea(Xin North Korea Cold Noodle Restaurant), Sìchuān四川(Laomashou Ganmian老妈手擀面), Germany(Golden Hands金汉斯(红旗街店)), Japan(Yoshinoya), and Huízú回族. These hotels prepare wonderful foods also: Redbuds Hotel, Chang Bai Shan Hotel, Shangri-La Hotel. Lots of ginseng that you buy in Canada comes from Changbaishan which isn't far from Changchun. Jilin Province is the largest producer of ginseng, producing 85 percent of the country's total and over 70 percent of the world's total amount. Shy Grass, Mushroom Wine, Chuan Popo Spicy Sichuan Sauce and other marvellous wonders can also be found at the Changchun Agricultural Fair. The best cartoon I have ever seen is 中華一番之滿漢傳奇(Zhōnghuá yī fān zhī mǎn hàn chuánqí) Cooking Master Boy 中華一番!(Chūka Ichiban!).

If it's not good for everyone, it's no good at all

Ubuntu Party's “If it’s not good for everyone, it’s no good at all.” does relate and fit in well to Adequatech's position and application towards Digital Freedoms, net-neutrality, censorship, open-source, accountability and transparency. Ubuntu Party's presentation states:
Most of our ancient cultures had a saying that “if it’s not good for everyone, it’s no good at all.” In Africa, they called it UBUNTU. But this philosophy was shared by hundreds if not thousands of ancient cultures all over the world.
नमस्कार एन्ग्लिश bonjour
Ubuntu Party is worthwhile for others to read about it, to reflect about it and to apply it.
