What is a Kubernetes Node?

Deep dive into what defines a Kubernetes node, what is a container runtime and how Kubernetes interacts with them to orchestrate containers. As usual, driven by live demos.

How we can run pods without nodes?

Introduction to managed container services, how to use them with Kubernetes and what providers are available. Live demo using the Azure Kubernetes Engine.

Going 100% nodeless kubernetes in AWS

How to run an AWS EKS cluster without a single EC2 instance.

Extending the Kubernetes API with Custom Resources, Controllers and Operators

Wed, 18 Sep 2019 18:30:00 +0200

What is the controller pattern? And the operator pattern? How we can use custom controllers to extend the Kubernetes API? How we can build our own custom resources, controllers and operators?

Join at meetup.com/Cloud-Native-Barcelona

Slides at go.rael.dev/cnbcn-extending-k8s The talk will be streamed live at https://glovoapp.zoom.us/j/364754734.

Agenda

18:30 Welcome

Contributing to Kubernetes

Thu, 16 May 2019 18:30:00 +0200

Since the addition of multilingual support for the Kubernetes website in November (https://kubernetes.io/blog/2018/11/08/kubernetes-docs-updates-international-edition/), the support from the community has been amazing and currently 10 localisation teams are working to make the documentation more accessible by breaking the language barrier.

Doesn’t matter if you are an expert user or just started playing with Kubernetes, you can add new documentation from your own experience or based on the English knowledge base, review existing documentation or just fix typos, any contribution would be appreciated!

Cloud Native Barcelona

Tue, 01 May 2018 16:30:13 +0200

Cloud Native Barcelona is the official Cloud Native Computing Foundation user group dedicated to building a strong, open, diverse developer community around the Cloud Native platform and technologies in Barcelona.

Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach.

These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil.

Maps

TODO

Definition scope

Functions

var y int = foo(1, 2) // compile error, wrong number of arguments
var z int = foo(1, 2, "bar") // compile error, last argument not a bool
var v bool = foo(1, 2, true) // compile error, wrong return type
a := 1
b := 2
s := foo(a, b, true) + a // OK, compiler knows that a, b and foo are int
str, num := bar() // OK
}

Syntax

Semicolons are inserted by the compiler

func foo(x int) int {
x++
return x

foo(1)

The compiler will put the ;:

func foo(x int) int {
x++;
return x;
};
foo(1);

### Loops

abc := [3]string{"a", "b", "c"}

Bot to forward messages between supergroups and private chats, to allow talking in Telegram supergroups when banned.

Why

Sometimes, due to trolls reporters, users can be banned from any Telegram supergroup, not only the one where reported. With this bot, users will be able to participate in specific groups through the bot.

This bot can be added to the group, identified by TELEGRAM_GROUP_ID, and will:

Forward any message from the Group to the private conversation with the banned user
Forward any message from the private conversation with the banned user to the Group

The admins of the groups where the bot is a member will decide if the allows the banned users to participate or not.

Disclaimer

This bot is not intended to be a tool for spammers and malicious users to bypass Telegram bans. The purpose is to allow users to interact in the groups with the authorization of the group admins when globally banned from supergroups due to troll reportings.

PyBot

Thu, 02 Mar 2017 11:23:56 +0200

pybot

Wrapper for python-telegram-bot to allow dynamic plug-in architecture, an attempt to make python-telegram-bot more hubottish.

Execution flow

bin/pybot starts the bot with the selected adapter and using the configuration options defined in conf/pybot.conf or the command-line arguments.
The selected adapter receives the message and sends it to the brain.py.
The brain.py loads in runtime all the .py files in the ./memory folder each time and try to execute a defined method, for example hear(message.text).
Each module in ./memory with that method returns a response, the brain.py sends it to the pybot.py and it sends the response back to the chat.

As the methods are dynamically loaded, you can edit and add the files in ./memory without need to restart pybot.py, and they will be reloaded on the next message. Overkill but funny.

Makefile targets

usage: Show this help
setup-venv: Setup virtualenv

Hubot Raelbot

Sun, 16 Aug 2015 11:23:56 +0200

raelbot is a chat bot built on the Hubot framework.

Running raelbot Locally

You can test your hubot by running the following, however some plugins will not behave as expected unless the environment variables they rely upon have been set.

You can start raelbot locally by running:

% bin/hubot

You’ll see some start up output and a prompt:

[Sat Feb 28 2015 12:38:27 GMT+0000 (GMT)] INFO Using default redis on localhost:6379
raelbot>

Then you can interact with raelbot by typing raelbot help.

raelbot> raelbot help
raelbot help - Displays all of the help commands that raelbot knows about.
...

Persistence

If you are going to use the hubot-redis-brain package (strongly suggested), you will need to add the Redis to Go addon on Heroku which requires a verified account or you can create an account at Redis to Go and manually set the REDISTOGO_URL variable.

% heroku config:add REDISTOGO_URL="..."

If you don’t need any persistence feel free to remove the hubot-redis-brain from external-scripts.json and you don’t need to worry about redis at all.

Adapters

Adapters are the interface to the service you want your hubot to run on, such as Campfire or IRC. There are a number of third party adapters that the community have contributed. Check Hubot Adapters for the available ones.

If you would like to run a non-Campfire or shell adapter you will need to add the adapter package as a dependency to the package.json file in the dependencies section.

Once you’ve added the dependency with npm install --save to install it you can then run hubot with the adapter.

% bin/hubot -a <adapter>

Where <adapter> is the name of your adapter without the hubot- prefix.

Deploying to UNIX or Windows

If you would like to deploy to either a UNIX operating system or Windows. Please check out the deploying hubot onto UNIX and deploying hubot onto Windows wiki pages.

I’ve been deploying servers since I was fifteen, at first as a hobby and then as a career. During the last decade, the cloud has changed how we use information technologies and made accessible to everyone an unimaginable computing power.

This change triggered several revolutions, one of them, the rise of open source technologies to take advantage of those compute resources and build amazing things. The tools and solutions now are out in the open, driven by the community and available to anyone who wants to use them, get involved in the project or change them to match their needs.

Open source projects enable an innovation speed never seen before and are democratizing the cloud ecosystem. Companies and users now are building their ideas and business on top of open-source cloud-native technologies that give you the freedom to run your workloads anywhere.

I would like to be part of that revolution.
