For my own company MySocialApp, I’m managing multiple Cassandra clusters on top of a Kubernetes on premise cluster. For those who never heard of this distributed database, here is the summary from the official website: The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.

For a new project (will talk about it later), I needed to use Neo4J (graph database if you don’t know it yet). I tried to cover more features than the current existing Ansible roles available on Ansible Galaxy. More will come in the next weeks. I also tried to make it simple to install it and do not force dependencies at maximum. Here are parameters you can set: # Select neo4j version neo4j_package: neo4j # community version #neo4j_package: neo4j-advanced #neo4j_package: neo4j-enterprise # Neo4j spatial plugin neo4j_install_spatial: false neo4j_spatial_version: '0.

For my personal usages, I wanted do use DotDeb and MySQL playbooks. I first looked at the current ones on the Ansible Galaxy. However I did not find a good one for my needs. I first wanted to try to contribute to an existing one. But I needed to have them quickly and unfortunately didn’t have the time to do it. That’s why I made 2 new Ansible roles and added them to Ansible Galaxy.

Following the deployment blog post I made on ES/Kibana/Fluentd, I released new version of Fluentd and Kibana playbooks to support the latests versions of themselves and ElasticSearch. ElasticSearch 1.4 version is ,out which doesn’t changed anything for the deployment. However Kibana requires to enable an ElasticSearch configuration option now, to work properly. I updated the Kibana playbook for it. On its side, Fluentd has the major release 2.0 out and I updated Ansible playbook for the best integration with Debian Wheezy.

As I do not really have a good blog post for today, here are some things I wanted to talk in a summary.
