Watching out for Docker

After an intense 2 weeks of deep dives into everything docker I find myself with a very short list of URLs that I need to monitor:

Docker - of course
CoreOS - naturally
fig - cool
boot2docker - required
deis - sigh
kubernetes - ditto x2
Rancher - used it when it was very promising.
Rancher is making a comeback

Phusion has a lot to say about container contents but it's very scary.

Building good docker images - some ideas about creating good docker images.
Reverse proxy with nginx.
Docker patterns.
Continuous integration with DroneIO
systemd alarm clock
citadel docker API
Project Atomic, Dokku
Vulcand, zero downtime deploy
WeaveDNS is one way to make service discovery easier. Weave is a network partitioning tool that could also be useful. And some boot2docker DNS.

multi-server docker.

Under Review
kitematic - docker on your mac
bowline - build server and UI for docker
artifactory - recently added docker registry to artifactory

UPDATE: flynn - I discarded my interest in flynn. The previous pre-release was in Aug and now another that uses Docker 1.3.1. If memory serves there was a strong dependency on a fix that was supposed to be available in Docker 1.3.0 so it's worth reviewing again. Flynn's website still indicates it's not ready for production.

The latest version of Docker is 1.3.0. There were a number of interesting features added to this version but nothing that is actually a game changer. There was one bug that I reported that seems to be fixed so I can take advantage of the patch in the CoreOS alpha channel.

** although docker is getting considerable mindshare I'm starting to rediscover my interest in appscale and google app engine.

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: (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).


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…
