Initial version of Automated DB Updater Release ADU

With this blog I'm releasing the intial version of a python utility to provide automated db updates across various environments for different components.

The code for this utility is hosted on github
https://github.com/sandy724/ADU

You can clone the read only copy of this codebase by url given below
https://github.com/sandy724/ADU.git

To understand the basic idea about this utility go thorugh this blog
http://sandy4blogs.blogspot.in/2013/07/automated-db-updater.html

How to use this utility
    Checkout the code at some directory, add the path of this directory in PYTHONPATH environment variable
    Create a database with a script's metadata table with given below ddl
CREATE TABLE `script_metadata` (
  `name` varchar(100) DEFAULT NOT NULL,
  `version` int(11) DEFAULT NOT NULL,
  `executed` tinyint(1) NOT NULL DEFAULT '0',
  `env` varchar(30) DEFAULT NOT NULL,
  `releas` varchar(30) DEFAULT NOT NULL,
  `component` varchar(30) DEFAULT NOT NULL
)
    Create a database.properties, containing connection properties of each environment database

[common_db]
dbHost=localhost
dbPort=3306
dbUser=root
dbPwd=root
db=test


[env1]
dbHost=localhost
dbPort=3306
dbUser=root
dbPwd=root
db=test

Here common_db represents connection to database which will contain metadata of scripts for monitoring

    Now execute the pythong utility
        Copy the client(updateDB.py) to directory of your choice, make sure that property configration file should also be at this directory
        python updateDB.py -f -r --env

EC2 Ssh Connection Refused

When ssh: connect to host ip_address port 22 Connection refused



Unable to access server???
Exactly when you see the error - “ssh: connect to host ip_address port 22: Connection refused” while connecting your AWS EC2 Instance. In order to find solution of the problem, you will go to AWS forum and other channels where you need to answers several questions first. But it's very difficult to find the actual problem. In order to get clues what the problem is, we should provide as many details as possible about what we have tried and the results we are getting. Because there are hundreds of reason why a server or service might not be accessible, also connectivity is one of the toughest issue to diagnose, especially when you are hosting something critical on your box. I've seen several topics on this problem, but none offers a solution to it.  I was not aware for what should I look at first. So I walk through from the very basics and investigated the following thing Use of verbose while ss…

jgit-flow maven plugin to Release Java Application

Introduction As a DevOps I need a smooth way to release the java application, so I compared two maven plugin that are used to release the java application and in the end I found that Jgit-flow plugin is far better than maven-release plugin on the basis of following points: Maven-release plugin creates .backup and release.properties files to your working directory which can be committed mistakenly, when they should not be. jgit-flow maven plugin doesn't create these files or any other file in your working directory.Maven-release plugin create two tags.Maven-release plugin does a build in the prepare goal and a build in the perform goal causing tests to run 2 times but jgit-flow maven plugin builds project once so tests run only once.If something goes wrong during the maven plugin execution, It become very tough to roll it back, on the other hand jgit-flow maven plugin makes all changes into the branch and if you want to roll back just delete that branch.jgit-flow maven plugin doesn…

VPC per envrionvment versus Single VPC for all environments

This blog talks about the two possible ways of hosting your infrastructure in Cloud, though it will be more close to hosting on AWS as it is a real life example but this problem can be applied to any cloud infrastructure set-up. I'm just sharing my thoughts and pros & cons of both approaches but I would love to hear from the people reading this blog about their take as well what do they think.


Before jumping right away into the real talk I would like to give a bit of background on how I come up with this blog, I was working with a client in managing his cloud infrastructure where we had 4 environments dev, QA, Pre Production and Production and each environment had close to 20 instances, apart from applications instances there were some admin instances as well such as Icinga for monitoring, logstash for consolidating logs, Graphite Server to view the logs, VPN server to manage access of people.




At this point we got into a discussion that whether the current infrastructure set-u…
