Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Docker Networking: A Step-by-Step Guide for Developers
Now, let's use netshoot, a Docker image equipped with a set of networking troubleshooting tools that can be used for Docker networking.
-
What's your favourite Docker Image, and why?
nicolaka/netshoot for sure. having a preloaded array of networking troubleshooting tools in an image for kubernetes debugging is a godsend.
- k8s docker image with basic troubleshooting tools
-
Networking lab for learning using containers?
First off, it seems like getting tcpdump or Wireshark to capture from the container network and dumping to a file will take some extra steps. (A lot of blog posts seem to recommend this Github project - https://github.com/nicolaka/netshoot)
-
New to ubuntu and stumped by my cloudflare tunnels suddenly no longer working...
Some hints how to debug such problems in the future: 1. ufw drops/rejections are logged (use dmesg to view them) 2. wireshark shows all connection attempts, even those that are blocked by firewall 3. ss or netstat shows if the server is actually listening for connections 4. netshoot allows to enter docker container network namespace and do pings, curl or telnet from there
-
Isolating Kubernetes pods for debugging
If you feel at home in the command line, you should check out netshoot — a Docker + Kubernetes network trouble-shooting swiss-army container.
-
Image for web server that serves Kubernetes details
The difference between what I am looking for and, for example, nicolaka/netshoot, is that this would automate different tests and queries and display it quickly.
-
Troubleshoot app connectivity on OpenShift
For this connection test, let's use a Netshoot container.
-
A debug container/pod for when you need to debug stuff in your cluster
Have you heard of netshoot yet?
-
Troubleshooting k8s - your recommendations for strategies and tools.
netshoot comes with a bunch of relevant tools pre-installed, so that's normally my goto when I need a troubleshooting pod on the host network.

Don't start with microservices – monoliths are your friend
I disagree, microservices are an architectural concept related to the software, not to the infrastructure.
Whether you are using containers or VPS or serverless or bare metal for your infrastructure, that's completely unrelated to the concept of microservices: you can deploy either a monolith or microservices in any of the above.
As an example you can deploy a monolith on Lambda[1] or you can deploy microservices on bare metal using one of the several self managed serverless engines available[2].

Serverless functions with FN project
Still, for today I would like to talk to you about the FN project, an open-source alternative.
-
Azure function like feature
Never really used it but perhaps you can look into Fn. There's also OpenFaaS, but that's for Kubernetes.
What are some alternatives?
OpenFaaS - OpenFaaS - Serverless Functions Made Simple
OpenWhisk - Apache OpenWhisk is an open source serverless cloud platform
Dokku - A docker-powered PaaS that helps you build and manage the lifecycle of applications
containers-roadmap - This is the public roadmap for AWS container services (ECS, ECR, Fargate, and EKS).
ksniff - Kubectl plugin to ease sniffing on kubernetes pods using tcpdump and wireshark
fission - Fast and Simple Serverless Functions for Kubernetes
container_builder - This project builds containers images using Ansible. The containers are defined as hosts in the Ansible inventory. They are generated using host and group variables, templates and local connection.
