Vagrant: manage Docker + VirtualBox easily

8 January 2015 in Debian, Developement, Docker, Hi-Tech, Linux, Red Hat, Vagrant

As you may know, I’m using Vagrant for more than a year now with VirtualBox. Docker is a faster alternative that needs to be taken into consideration. Having the possibility to manage both of them with the same tool can be very interesting. For information, I mainly use it with VirtualBox because it’s any platform compatible and Docker because it’s perfect for a CI like Jenkins. I recently talked about my implication into the Smash project.

Ansible: Fluentd and Kibana playbooks updated

9 December 2014 in Ansible, Databases, Debian, Hi-Tech, Linux

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.

NFS: recover your client connexion when server was down

25 November 2014 in Debian, Hi-Tech, Linux

I recently had the case, where I lost connexion of my NFS client connexion because NFS server crashed. The problem I had is simple, some of clients couldn’t recover their connexion because the old one was still shown as already connected. And when I tried to remount NFS clients connexions, I got: mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'udp,sec=sys,rsize=8192,wsize=8192,intr,hard,addr=10.0.0.1' mount.nfs: prog 100003, trying vers=3, prot=17 mount.nfs: trying 10.

Automatic package creation, which one to choose?

30 October 2014 in Debian, Hi-Tech, Linux, Red Hat

I’m currently developing a complete packaging stack based on Docker to easily make different kind of packages for several Linux distributions. This for MySecureShell project. This stack will be used to build packages in destination of upstream Linux distribution packages. But I’d like to provide a simpler and faster way to create custom repositories mainly for Debian, Ubuntu, CentOS and Fedora. In addition if packages could be automatically created when a new tag is pushed to the GitHub account, it would be perfect.

MySecureShell finally available in official Debian repository

28 October 2014 in Debian, Hi-Tech, Linux

You may know that I’m one of the 2 founders of MySecureShell. Around 6 years ago, we made a quick try to send MySecureShell to Debian and didn’t make enough efforts to make it possible. This time I worked hard to make this happen. Thanks a lot to Gonéri Le bouder, a colleague and Debian dev to make it possible and helped me to do it fast, before Jessie freeze.
