We’re super chuffed to see another THREE posts from our illustrious community – Adam Young talks about api port failure and speed bumps while Lars explores literate programming.
Shift on Stack: api_port failure by Adam Young
I finally got a right-sized flavor for an OpenShift deployment: 25 GB Disk, 4 VCPU, 16 GB Ram. With that, I tore down the old cluster and tried to redeploy. Right now, the deploy is failing at the stage of the controller nodes querying the API port. What is going on?
Self Service Speedbumps by Adam Young
The OpenShift installer is fairly specific in what it requires, and will not install into a virtual machine that does not have sufficient resources. These limits are 16 GB RAM, 4 Virtual CPUs, and 25 GB Disk Space. This is fairly frustrating if your cloud provider does not give you a flavor that matches this. The last item specifically is an artificial limitation as you can always create an additional disk and mount it, but the installer does not know to do that.
Snarl: A tool for literate blogging by Lars Kellogg-Stedman
Literate programming is a programming paradigm introduced by Donald Knuth in which a program is combined with its documentation to form a single document. Tools are then used to extract the documentation for viewing or typesetting or to extract the program code so it can be compiled and/or run. While I have never been very enthusiastic about literate programming as a development methodology, I was recently inspired to explore these ideas as they relate to the sort of technical writing I do for this blog.
