Which tech do startups use most?

Leo Polovets of Susa Ventures publishes an excellent blog called Coding VC. There you can find some excellent posts, such as pitches by analogy, and an algorithm for seed round valuations and analyzing product hunt data. He recently wrote a blog post about a topic near and dear to my heart, Which Technologies do Startups […]

Sphinx in Docker. The basics.
+0 Vote Up -0Vote Down
With an ear to the interwebs, you’ll hear a few things about Docker. Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. In this blog post, I’m going to outline a very basic example of how to use Sphinx from within a Docker container. What is Docker? This [...]
CoreOS Review
+0 Vote Up -0Vote Down
I have spent a few days now playing with CoreOS and helping other members of HP's Advanced Technology Group get it running on their setups.
Today I thought I would write about the good and the bad about CoreOS so far.  Many components are in an alpha or beta state so things may change over the coming months.  Also as a disclaimer, views in this post are my own and not necessarily those of HP.

Installation


As stated in my blog post yesterday, I have been using CoreOS on my Macbook Pro using Vagrant and VirtualBox.  This made it extremely easy to setup the CoreOS cluster on my Mac.  I made a minor mistake to start with, and that is to not configure the unique URL required for Etcd correctly.  A mistake a colleague of mine also made on his first try so it

2xHipster (Docker and Galera) doesn't mean its good.
+0 Vote Up -0Vote Down

Ahoi,

There had been already a couple of blogposts about Docker and Galera in the MySQL community. I've got to confess I love both. But on the other hand I don't think this is a good combination at all. Having a look at the blogpost doing galera with docker Im still not confessed. Im going to tell some points why I think so.

I assume Galera is already well know in the MySQL community :)

Docker is not just another technique to virtualize

Docker is more than just being another way to virtualize. And this may be one of the biggest points I miss with the other blogposts.

What is the purpose of Docker?

With Docker you build applicationcontainers. So you have a container just running one application. The overhead of containers compared to hypervisor technologies like KVM, VMWare etc. is

How to setup Docker for Percona ClusterControl and add existing Percona XtraDB Cluster
+0 Vote Up -0Vote Down

In my previous post I showed you how to setup Percona XtraDB Cluster 5.6 on Docker. This time I will show you how to setup Percona ClusterControl and add the existing Percona XtraDB Cluster 5.6 that we’ve managed to setup from the previous post.

Let us note the following details about our existing containers:

  • 172.17.0.2 dockerpxc1
  • 172.17.0.3 dockerpxc2
  • 172.17.0.4 dockerpxc3
  • 172.17.0.5 dockerccui-test

Quick test run with infobright
+0 Vote Up -0Vote Down
After reading Jonathan Levin's article about infobright I decided I had to try Infobright.

So I downloaded the 32-bit tarball. Normally I would have gone for a 64-bit build but those only came in RPM and DEB flavour.

Then I tried to run infobright community edition (ICE) in a MySQL Sandbox, but that failed as the resolveip utility failed to give an answer for localhost.


error while creating grant tables
Neither host 'daniel-thinkpad' nor 'localhost' could be looked up with
/home/dveeden/opt/mysql/4.0.7-ice/bin/resolveip
Please configure the 'hostname' command to return a correct
hostname.
If you want to solve this at a later stage, restart this script
with the --force option

Then I used docker. This went

Installing Percona XtraDB Cluster 5.6 with the Docker open-source engine
+2 Vote Up -0Vote Down

In my previous post, I blogged about using Percona Server with Docker and have shown you how fast and easy it was to create a virtual environment with just a few commands.

This time I will be showing you how to setup a three-node Percona XtraDB Cluster (PXC) 5.6 on the Docker open-source engine. Just to review Docker… “is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.”

In this case we will make use of a Dockerfile, think of this more like the Vagrantfile, it is a build script with a set of commands automating

Using Percona Server 5.6 with the Docker open-source engine
+0 Vote Up -0Vote Down

There are a couple of posts about setting up Percona XtraDB Cluster on Vagrant and Percona Server on MySQL Sandbox – those are two of the top tools used by the Percona Support team for testing and bug processing among other things.

In this post, however, I will show you how to use Docker with Percona Server on Ubuntu 12.04.

As per Docker’s official site:

Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually

How to Deploy Galera Cluster for MySQL using Docker Containers
+0 Vote Up -0Vote Down
February 18, 2014 By Severalnines

Virtual Machines are great, and very useful when trying out new software. However, they might be an unnecessarily heavyweight solution when testing clusters, especially if these consist of multiple nodes running exactly the same software. Each VM runs a full-blown OS image. On the other hand, Linux Containers (LXC) are an efficient alternative to OS-level virtualization and can run multiple isolated systems on a single host. Docker is a wrapper around LXC, it automates the deployment of applications inside containers. 

A notable advantage if you run with Docker + LXC is you can run many containers on a single host.
