I just received my first two Pine boards (2GB ram models). My dream is to network these together for use as a Docker Swarm cluster that would host various applications that I develop -- sort of a home-grown replacement for AWS or Docker Cloud. Although I am pretty familiar with Docker, I am rather new at devices like Pine boards. Would anyone be able to help me understand what I need to do to get a reasonably performant cluster that can scale as I purchase more Pine boards?

Here are some questions/thoughts I have:


1) OS

I was thinking Debian base here.

2) Shared Storage

I want shared storage to store docker volumes so that every board in the cluster can mount the volumes into containers.

My first thought was to buy a 1 or 2 TB external hard drive, but:
    a) How do i connect all the boards to the drive? Do I need to have the drive connected to one board and then share the mount over the network?
    b) What can I expect for IO latency? I want to be able to run postgres database containers against the volumes on the external drive. How will that perform?

3) microSD storage per board

This hits a limit on my docker knowledge -- i'm not sure if i need to have internal storage for all the images that I want my swarm to run, or whether the images can be stored on the shared storage from 1) and just loaded into memory when i instantiate containers. If the images must be kept on the microsd, I guess i would need 32 or 64 GB. But if the images can be kept on shared storage, then i imagine i would only need a microsd large enough for the OS and whatever disk space the docker daemon needs to do its job.

4) Accessing over the internet via SSH

I was thinking instead of buying a static IP, which would require business class from my cable company, to use a service like http://www.noip.com/. I want to be able to SSH into this cluster via the domain name, and of course be able to hit web applications over HTTP.


This is as far as I have gotten so far. I am sure there are gaps in my understanding above. Also please point out to me anything I am NOT thinking of that is crucial to my goal of a personal docker swarm cluster -- any help is appreciated!!!

Hi,

I am trying to write to the android frame buffer as root and nothing shows up on screen.
cat /dev/urandom > /dev/graphics/fb0
Any ideas why this doesn't work ?

Hello all,

I want to bind the FIQ to a GPIO pin input processing.  Is this functionality available on the Pine64? 

I see definition of the pending request in drivers/irqchip/irq-sun4i.c,
#define SUN4I_IRQ_FIQ_PENDING_REG(x)    (0x20 + 0x4 * x)
but no reference or apparent support in the module.

Should I be looking elsewhere?

Thank you,   Joe

I have a working install using the pine64 touch screen monitor.  I was thinking I might want to use the HDMI output as an occasional option. However if I disconnect the touchscreen I get no signal out on HDMI. It will send a signal with screen connected but only a partial screen. Been a while since I did the install and for personal reason had to shelf working on the project. Does the install only work with the touch screen? Would I need another install to functionally use the HDMI.

Thanks

I am hoping someone can lead me in the correct direction here. I have had my Pine for quite a while now and I use it almost exclusively for KODI and it's been working great! However, after watching some TV two nights ago, I attempted to watch today and was met with no Ethernet connection. I am connected to the switch which is working fine, and the Pine works great when I boot up my Ubuntu Mate, but with the Android image, I have zero connection options.

I am not an Android guy myself, so I am not all too familiar with the ins and outs of the OS. Any help would be greatly appreciated.

Hi,
I've got 2 packages already but still didn't get all parts I've ordered and shipping@pine64.com doesn't respond to my reminding e-mails. Last time it was Lucy Duong on Pine64 side and she wrote on 15 September:

"No worries, I've notified the shipping department of your issue and they will reship your package as soon as possible!"

And no more information from that time, almost 2 months already 

1st package contained Pine64 boards, memory cards, wifi/bt modules, screens, batteries
2nd package contained 2x playbox cases with ribbon cable, and that's all..

I still didn't get:
1. ABS enclosure as part of IoT Kit
2. Z-wave module (EU) as part of IoT Kit

tllim can you help me?

Hi everyone.

Out of stupidity, I accidentally dropped my Pine64 to the floor. It's got the acrylic case and fell flat on the bolts from about 5 feet in the air.

Now, when I plug it in, I have the battery logo. The red led lights for about 10 seconds, flashes once, hold on for about another 5 and shuts down.

I've tried another SD with another OS. Nothing. The battery logo is all I got now.

Is my Pine64 dead?

Hello, good day. I'm trying to use my pine to setup a simpe nfs server with 3 HDDs. There's not enough power to get even one working so, how do I power up the disks to get them working in the pine? Thank you.

I have a Raspberry Pi that is a Flightaware ADS-B receiver. Has anyone tried to do this with a Pine64?

Is it possible?

PROBLEM: Random pin state (or pin ON) after boot.
can anyone tell how to define the state of pins after boot?
