I have been missing in action for a while, busy with work and other “stuff”. Since I last posted ….. Docker 1.0 has been released.↗ CentOS↗ 7 has been released↗ . I have updated the sites theme again to use So Simple↗ . Aphex Twin’s Long Lost Caustic Window LP was released.↗ Also new albums from Neil Finn↗ , Anathema↗ and Crippled Black Phoenix↗ have all been released. I have written a blog post for work↗ on MFA in AWS. ….. suppose I had better make more of an effort to post now that everything has caught up. ...

Having ran a local copy of OpenShift Origin↗ using VirtualBox↗ I decided to have a go at running it on a Digital Ocean↗ Droplet running CentOS 6.5. This should be easy as there is an installer↗ which claims; You’re one shell command away from deploying your own Platform as a Service. Well, sort of, after a few failed installs I finally managed it using the following (this assumes you are running a clean and minimal CentOS 6.5 installation) ...

I did a clean installation of my laptop this weekend, rather than go through the list of apps I had installed and do a manual installation of each one using the “Download and drag” method I decided to use Cask↗ . Cask is a Homebrew↗ package which automates to the download and install part. Here is pretty much my entire installation process ….

Sysdig↗ looks like it could be a useful addition to a sysadmins list of tools, it is described as; Sysdig is open source, system-level exploration: capture system state and activity from a running Linux instance, then save, filter and analyze. Think of it as strace + tcpdump + lsof + awesome sauce. With a little Lua cherry on top. It’s easy to install↗ ….

I had registered the domain DevOps-SysAdm.in↗ with the intention of creating a second Jekyll based site which was going to be a link dump for stuff. Instead I decided to use Tumblr↗ as that seemed alot less hassle. So go on, head over & follow↗ . Also, you can submit stuff↗

Since I have been playing with Docker for the past few weeks I have had more servers on-line. I don’t have a static IP address at home so while I have a jump host setup I found I was still being port scanned and brute forced. I only caught a sniff of it in the logs while looking at another problem, even though password authentication is disabled and I only use keys I decided install Fail2Ban↗ to start blocking people, just in-case. As I use Puppet↗ I installed a module and enabled it. Since then I have been flooded with emails !!! ...

Been listening to some old albums this past week, some I haven’t heard for years, such as …. Jellyfish — Bellybutton↗ The Wannadies — Be a Girl↗ Spacehog — Resident Alien↗ https://embed.spotify.com/?uri=spotify:album:6vOmA5zWeFeKvuRBxaO59↗ …. think I will revisit some more this week.

Since my last post about Docker I have been playing a lot more, rather than use a GUI like Shipyard↗ I decided to use @garethr’s excellent Puppet Module↗ to manage and deploy my containers. This allowed me to take a better look at the builds I had over at the Docker Index↗ . The following is a list of builds I have deployed so far ….. General Containers Base↗ — Base build for use with other Docker build Jump Host- Build which can be used as a SSH jump host Database Containers MySQL 5.5 — Build which runs MySQL 5.5 MySQL 5.6 — Build which runs MySQL 5.6 PHP Containers Apache & PHP 5.4 — Build which runs Apache with PHP 5.4 Apache & PHP 5.5 — Build which runs Apache with PHP 5.5 NGINX & PHP 5.4 — Build which runs NGINX with PHP 5.4 & PHP-FPM NGINX & PHP 5.5 — Build which runs NGINX with PHP 5.5 & PHP-FPM See the GitHub Repo↗ and my Docker Index Profile↗ for more information. ...
