etcd and fleet not starting with CoreOS running on GCE

Google Compute Engine (GCE) is a cool tool. If you do not know what it is you should check it out. Over the years they have made it more configurable that the limited selections that it started with. At one point you could load your own raw image and install that. Cool!

The best part is that I can deploy and destroy systems from a GUI, CLI, and API.

Now for the hard stuff.

I had a CoreOS installation, following the alpha channel, for almost a year now. In that year I have not had to do ANYTHING. In fact I lost my cloud-config file and was then able to recover it using both the CLI and the GUI.

One day, a few months ago, I lost the ability to connect to one of my subdomains.Between the naked domains on my nameserver and lighttpd acting as a reverse proxy... it just would not work.

What I discovered... (a) boot disk was full (b) no logs (c) etcd would not start (d) fleet would not start (e) my lighttpd container was deleted; it was a total mess.

Corrections:

The drive was full so I started cleaning up my images and instances. (not a great choice)

/var/log/btmp was HUGE and google results suggested I was under attack. So I deleted that file and it is already growing fast. There are a number of possible solutions from fail2ban and denyhost. I'll make a choice soon enough.

Ran my docker build and run commands for my lighttpd container

Removed the etcd and fleet sections in my cloud-config because my CoreOS instance was a single and those config options were for multinode.

And then it worked.

NOTE:  Rocket is now installed by default. NICE!

UPDATE: Just a helpful link. More etcd info link and link.

Entry level cost for CoreOS+Tectonic

CoreOS and Tectonic start their pricing at 10 servers. Managed CoreOS starts at $1000 per month for those first 10 servers and Tectonic is $5000 for the same 10 servers. Annualized that is $85K or at least one employee depending on your market. As a single employee company I'd rather hire the employee. Specially since I only have 3 servers.

The pricing is biased toward the largest servers with the largest capacities; my dual core 32GB i5 IntelNuc can never be mistaken for a 96-CPU dual or quad core DELL

If CoreOS does not figure out a different barrier of entry they are going to follow the Borland path to obscurity.

UPDATE 2017-10-30: With gratitude the CoreOS team has provided updated information on their pricing, however, I stand by my conclusion that the effective cost is lower when you deploy monster machines. The cost per node of my 1 CPU Intel NUC is the same as a 96 CPU server when you get beyond 10 nodes. I'll also reiterate that while my pricing notes are not currently…

eGalax touch on default Ubuntu 14.04.2 LTS

I have not had success with the touch drivers as yet.  The touch works and evtest also seems to report events, however, I have noticed that the button click is not working and no matter what I do xinput refuses to configure the buttons correctly.  When I downgraded to ubuntu 10.04 LTS everything sort of worked... there must have been something in the kermel as 10.04 was in the 2.6 kernel and 4.04 is in the 3.x branch.

One thing ... all of the documentation pointed to the wrong website or one in Taiwanese. I was finally able to locate the drivers again: http://www.eeti.com.tw/drivers_Linux.html (it would have been nice if they provided the install instructions in text rather than PDF)
Please open the document "EETI_eGTouch_Programming_Guide" under the Guide directory, and follow the Guidline to install driver.

Prometheus vs Bosun

In conclusion... while Bosun(B) is still not the ideal monitoring system neither is Prometheus(P).

TL;DR;

I am running Bosun in a Docker container hosted on CoreOS. Fleet service/unit files keep it running. However in once case I have experienced at least one severe crash as a result of a disk full condition. That it is implemented as part golang, java and python is an annoyance. The MIT license is about the only good thing.

I am trying to integrate Prometheus into my pipeline but losing steam fast. The Prometheus design seems to desire that you integrate your own cache inside your application and then allow the server to scrape the data, however, if the interval between scrapes is shorter than the longest transient session of your application then you need a gateway. A place to shuttle your data that will be a little more persistent.

(1) storing the data in my application might get me started more quickly
(2) getting the server to pull the data might be more secure
(3) using a push g…
