It can’t be helped. There’s just too much cool stuff out there and not enough time to spend dedicating myself to one piece of technology. That being said, I fully intend on continuing the Chef posts, but Im going to be mixing in some docker posts as well. Im hoping that there’s some cross-connect as well where we can talk about using docker in conjunction with Chef as well.
Docker is something that I haven’t seen before. From what I have seen so far, it appears to be an incredibly easy way to containerize applications and software on a linux system. The docker website summarizes docker as..
“An open platform for distributed applications for developers and sysadmins.”
That summarizes things nicely, but again, why is a network guy interested in this? First off, I’m a little tired of VMware. Don’t confuse me being tired with a general dislike of the product. I’ve been using VMware for years and for the most part, it works well and provides the functions I need. On the flip side, Im not convinced there’s anything particularly special about VMware.
You might be asking yourself why a network engineer would be concerning himself with a product like Chef. It’s a long story, but lets start by saying that my interest was first peaked when I heard that the new line of Cisco Nexus switches would have a integrated Chef client. I’ve known about Chef and Puppet for a long time, but I’ve never really sat down and looked to see how they worked. So rather than starting with Chef on Nexus, I thought it would be prudent to get some base experience with the application in a more ‘normal’ application.
So how does this fit into networking? I think we can all agree that data center networking can change. I’m carefully phrasing that statement by using the word ‘can’. If you don’t know it already, I don’t buy the ‘SDN will change everything you do’ line of thinking. In fact, I try as hard as I can not even to use the term SDN. Why? Because it’s far too vague of a term that can mean almost anything depending on you how you want to interpret it. Beyond being a Continue reading
