Comments

In the previous post, Home DC 02, I’ve outlined the requirements and an environment/scenario for a single-node AIO kolla / kolla-ansible OpenStack deployment, the first piece in the Home DC. Now, I’m going to walk through the actual actions taken on the single server to get to the point where OpenStack is running.

Sep 15, 2019 - Home DC 02: Single-node OpenStack with Kolla

Comments

In the the first Home DC post, I introduced some of the hardware I made available for the purpose of deploying a home/lab cloud/cluster/datacenter (or many). I have some ideas about what to do with this hardware but will leave that to another day, another post. Today I want to give you an introduction to my simple recipe for deploying a single-node AIO (all-in-one) OpenStack based on kolla / kolla-ansible. I’ll go through the hardware and network requirements and environment used. The next post will walk through the steps to setup this deployment and outline some of the difficulties I faced until the deployment was easily reproducible.

Sep 6, 2019 - Delay switching from Wi-Fi to LTE on T-Mobile

Comments

This is an Android-specific post but perhaps could apply to iPhone/iOS as well. When I got my OnePlus 6T (T-Mobile locked, though I don't think this is related), I don't remember experiencing any network connectivity issues or weaker-than-expected LTE signal. However, at some point, switching from Wi-Fi to cellular data became a problem. It would consistently take more than 3 minutes, no exceptions, to be able to surf the web over LTE (or any other cellular technology) after turning off Wi-Fi.


The triggering cause of this issue was having configured Android to use CloudFlare's 1.1.1.1 public DNS resolver. If you know how to disable the custom DNS configuration in your phone, great - that's all you need to do. Otherwise, continue reading.

Dec 31, 2018 - Home DC 01: Planning my first personal Dev Cloud(s)

Comments

In this post I cover the plan, ideas and hardware for my own private DataCenter / Dev Cloud - project Home DC.

After being mostly absent from the OpenStack community and OpenStack contributions for the past year and a half, and from Open Source in general for almost a year (after implementing IETF SFC "friendly" extensions to networking-sfc in OpenStack Neutron and initial VNF Forwarding Graph capabilities in OSM, the Open Source MANO), I will finally be returning to OpenStack Neutron development in 2019.
