Docker 🐳

==PLEASE NOTE: THESE INSTRUCTIONS ARE NOW OUTDATED, SEE THIS POST FOR AN UPDATE== After I dabbled with CentOS 7 a few weeks ago I decided to take the plunge and upgrade the few servers I run at DigitalOcean↗ to CentOS 7. I run two machines, one is a Puppet and Salt Master, the second runs Docker. Puppet Master Server A while back I added a few bash scripts to deploy both a Puppet Master & Agent↗ to GitHub, as Puppet provide a repo for CentOS 7 I decided to just update the installation script to use this repo and then give ago. I use stephenrjohnson/puppet↗ to deploy the Puppet Master. the Puppet part worked, however it failed to install Passenger and its Apache module because there is no mod_passenger available for CentOS 7 yet. To get around this I grabbed the require packages from The Foremans nightly builds↗ repo. This turned the initial yum install line into the following; ...

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) ...

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. ...

Been playing with Docker↗ again this weekend, this time rather than just doing for the sake of doing it I went for something a little more stable. I started off by creating a new DigitalOcean↗ droplet with the latest CentOS installed to run as a base. I then installed docker using the Docker Puppet Module↗ . So now I had Docker installed now what? I looked at some PaaS services, a bulk of them require Ubuntu (which I simply don’t do on servers), however Shipyard↗ looked good. It was simple to install; ...

Been playing a little with Docker↗ this afternoon, while its something I have been aware for a while its not something I have really looked into. As I prefer working with CentOS rather than Ubuntu its taken me a while to get the motivation to do any more than some reading, however as the latest version now runs on RHE compatible Docker 1/4 yum install http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm yum -y install docker-io service docker start chkconfig docker on Once the services are installed pull down some images to test with; ...
