OpenFaas on Docker Swarm on Raspberry Pi

-
OpenFaas is a server-less framework for running functions on docker containers. It's wicked easy to configure, and deploy functions. I was impressed to find out that you can deploy it to Docker Swarm on a Raspberry Pi! How neat.

Step 1) Install Docker
> curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh
Step 2) Configure OpenFaas by following there really well done tutorial on OpenFaas.com

Step 3) Configure a registry. Since you already have docker swarm running, deploy a stack with a registry running. Note, make sure to create the directory /data/registry.
version: "3.3"
services:
repo:
image: registry:2
ports:
- 5000:5000
volumes:
- '/data/registry:/var/lib/registry'
and deploy with
> docker stack deploy -c docker-stack.yml infra
Step 4) Setup on Work Station. You only have have Docker and OpenFaaS CLI installed. Once you do that you should be good to go. Note that if you want to deploy to that registry you have to add it to your "insecure repositories" section in your settings.

Nice things to try

Create new function

> faas-cli new func-demo --lang python3-armhf --prefix raspberrypi:5000

Deploy function

> faas-cli up -f func-demo.yml --gateway raspberrypi:8080

Test New Function

> curl -d "hello" http://raspberrypi:8080/function/func-demo
hello

Async Standups

 In the more global world that we live in, people are not only working remotely, but people are working across the globe and critically across many time zones. Due to our global reach even within a team, we have less daylight that we share with our coworkers. In the past, I’ve been part of very successful remote standups, but I noticed they only really work well if you are in close time zones. If you only have 1 hour of overlap with your coworker, do you really want to be going over high-level status with your broader team? I’ve asked my teams about this, and I got a very loud “NO!” We all use Slack as a communication tool, so I started an experiment with a team where a bot posts in the channel at the beginning of the earliest person on the team’s day. It asks a few simple questions: @team-name welcome to today and good morning! What did you work on yesterday? What are you intending to work on today? What blockers do you have on your priorities? What help do you need? As people trickle

Supporting People, Process, and Projects

When you approach a bridge that overlooks a river do you tend to look upriver at the past, or downriver to see the future? I am naturally drawn to looking downriver because I like to plan for the future. For the role of manager, you have three major areas of responsibility, the people, the projects, and gluing those together. That last part is where the magic happens. If you get great alignment with your people and what they work on, that is where you have the best outcomes. People Helping people thrive is the cornerstone of any people manager. How we align people and set them up so that they can be at their best self is critical to our success, and the success of the company. It's a win-win-win situation. It all starts with hiring and onboarding. For me, there are three critical areas that I focus on during the interview process. Do they have a growth mindset, do they include others during their decision-making process, and overall is the candidate a kind human being? Beyond the

Year in Review - 2021 Edition

 Holy buckets, 2021 went by quickly. Felt like 6 months! It's been a very rollercoaster year, but here we are, about to reenter the start/finish line and preparing to start another year. Starting off, we are still going through this pandemic, that has had an impact on my goals and aspirations, more on that later. Regardless, on to the review section. Looking back, I didn’t ever publish my 2021 goals, LOL. My general ideas were to stay healthy, and read a book per month. I read a lot more this year, reading 10 books (2 shy of my goal of 1 per month), and even enjoyed a few non-fiction books this year. We built a house and moved to a new town (still near Madison) and have really been enjoying the quieter life and funny enough my walking score here is way better than when I lived on the edge of the city. This was pretty huge part of the first half of the year. My kiddo started preschool and is really having a lot of fun. I did a bit of working out, more on that later. I took on a new
