5 Features I Like About Material for MkDocs

Steve Martinelli — Sat, 28 Nov 2020 06:46:02 +0000

Recently, I spent a few days experimenting with Material for MkDocs. In short, I'm impressed with the project and hope it continues to gain traction. It does, as the project tag line suggests...

Technical documentation that just works.

In this blog post, in no particular order, are five things I like about the Material for MkDocs project.

If you're interested in seeing what I built using Material for MkDocs, check out https://stevemar.github.io/minimal-workshop-mkdocs/.

About Material for MkDocs

If you're not familiar with Material for MkDocs, it's one of many options to host your open source technical documentation. If you're familiar with GitBook, it's like that. It, like most other projects with similar goals, relies on the documentation being written in Markdown.

It has wonderful documentation, a very well maintained and active repo, and boasts an impressive list of users, like AWS or Kubernetes

1. Fantastic looking graphical

The first thing I'll mention is that Material for MkDocs supports a variety of markdown plugins out of the box, enabling it to have some great user interfaces for your static site. Here are my three favorites:

Admonitions

Admonitions are available and come with 12 different display settings. Depending on what label you use in your admonition you get a particular color and icon.

Tabbed content

Another feature I like is that you can display tabbed content on your page. For instance, if you had some commands that a user should run depending on an operating system (Windows, Linux, or Mac), this would work perfectly.

Buttons

This probably shouldn't be a big deal, but adding a simple button to a static site is usually one of those steps that is harder than it should be. With Material for MkDocs it's very simple.

2. Social media footers

The next neat feature lies in the footer. Adding all brand icons is very easy and done in minutes.

A full list of supported brand icons is in the project repo.

3. GitHub Actions integration

I'm a fan of GitHub Actions (see my previous posts "Removing unused images" and "Deploying to IBM Cloud Kubernetes"). So seeing that Material for MkDocs deplyed to GitHub pages via GitHub Actions got me excited. You just need to drop this code in the usual .github/workflows path. Turn on GitHub Pages to deploy from the gh-pages branch, and you're live!

name: ci
on:
  push:
    branches:
      - main
      - master
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-python@v2
        with:
          python-version: 3.x
      - run: pip install mkdocs-material
      - run: mkdocs gh-deploy --force

4. Easy to set up

Material for MkDocs says "get up and running in 5 minutes". And yeah, I can say that the statement is accurate.

Install the package;

pip install mkdocs-material

Place a config file mkdocs.yml in the top level directory. Minimally, you need the contents below. And put all your markdown files in a docs folder.

theme:
  name: material

Run and test the site locally with:

mkdocs serve

5. All goverened by a single file

As long as you don't extend the base theme, the site's style and layout is governed by a single file. Which, if you're controlling multiple repositories and looking for consistency, makes things much more manageable.

Here's a snippet of what I use, check out my complete config file over here:

# Theme
theme:
  name: material
  features:
    - navigation.tabs

# Project information
site_name: Minimal Workshop
site_url: https://stevemar.github.io/minimal-workshop-mkdocs
site_author: IBM Developer

# Repository
repo_name: minimal-workshop-mkdocs
repo_url: https://github.com/stevemar/minimal-workshop-mkdocs

# Navigation
nav:
  - Welcome:
    - About the site: index.md
  - Workshop:
    - Lab 1: workshop/lab-1.md
    - Lab 2: workshop/lab-2.md
    - Lab 3: workshop/lab-3.md

Final thoughts

Material for MkDocs is a great project. It's maintainer, Martin Donath, is passionate about the project and is basically it's sole maintainer. The project is entirely open source but does use the sponsorware release strategy, meaning new features are first exclusively released to sponsors. If you're interested I encourage you to check it out.

Byte-Sized Tech Tips Round-Up: Week 7 (The Vim Edition 💻)

Steve Martinelli — Fri, 20 Nov 2020 20:15:03 +0000

This week's round up has a special theme, it's all about Vim! At our weekly meeting someone had mentioned using Vim, which of course turned into a conversation about all the tips and tricks for using it. Let's start!

Tip 1: Nigel's tip

From Nigel

One of my favorite modifiers in Vim is being able to modify certain commands with numbers. When I want to delete a line, I use dd, but if I needed to delete three lines, I use d3d. This works with several commands and I encourage you to check it out.

Tip 2: Make learning Vim fun!

From

If you’re looking to learn Vim, or have dabbled a bit and want to become a Vim Jedi, I’ve put together some fantastic resources to get you started! Vim Adventures is a comprehensive Vim online game to teach you all things Vim. Vim Genius will help you flex your Vim muscle memory and build up your skills and speed. If you prefer to work through technical documentation, Learn Vimscript the Hard Way is a great resource for manually working through all things Vim. Oh, and I did I mention they’re all FREE?!? Gotta love online resources

Tip 3: Double Z and NERDTree

From

Steve MartinelliFollow

Canadian | IBMer | FOSS | Python | Kubernetes

I'm cheating a bit and including two tips. We've all seen a joke about being unable to quit Vim, i.e.:

// Detect dark theme var iframe = document.getElementById('tweet-435555976687923200-350'); if (document.body.className.includes('dark-theme')) { iframe.src = "https://platform.twitter.com/embed/Tweet.html?id=435555976687923200&theme=dark" }

The good news is that there's an easy way! (No, really!)

Slam the ESC key a bunch of times.
Press Shift + Z twice (Double Z)
You've exited Vim!

The second tip is that if you really want to impress folks with your Vim skills install the NERDTree plug-in.

NERDTree will add a file system explorer for the Vim editor, allowing you to switch between editing multiple files without ever having to leave Vim.

Byte-Sized Tech Tips Round-Up: Week 6

Tip 1: Use `skaffold` to test your code quickly

Want to quickly test your Kubernetes service in a cluster, but don’t have the CI/CD set up or don't want to wait for pipelines to deploy your code? I use skaffold when developing locally while deploying to a cluster. It's easy to use in just a few steps!

1. Install skaffold

Get it from here.

2. Create a `skaffold.yaml` file.

I use something called profiles for testing, integration and production environments. Well maybe not production. That should always be CI/CD and maybe even a manual push (up for debate). Here is an example skaffold file with helm. You don’t have to use helm in order to use skaffold:

apiVersion: skaffold/v2beta6
kind: Config
profiles:
  - name: test
    activation:
      - command: test
    build:
      artifacts:
      - image: <namespace>/<cluster>/rulesdecision
    deploy:
      helm:
        releases:
        - name: rulesdecision
          chartPath: chart/rulesdecision
          artifactOverrides:
            rulesdecision:
              image:
                repository: <namespace>/<cluster>/rulesdecision
          overrides:
            rulesdecision:
              namespace: test

3. Run `skaffold -p deploy`

That’s it! Skaffold will automatically create a new image, load it to your repository and deploy the build on the cluster. It then refreshes the deployment with a new image when you make changes and save. The whole process is like deploying locally, but you are deploying to a cluster. How cool is that! Big caveat is that the deployment artifact will be removed when you quit the skaffold command.

Tip 2: Give your Discord bot a voice

This week I was able to configure a bot with a voice channel on a Discord server.

You start by installing discord.js with npm:

npm install discord.js @discordjs/opus

The next step is to create an index.js file.

const Discord = require('discord.js');
const client = new Discord.Client();
const Token = "<YOUR-BOT-TOKEN>";
client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('message', async message => {
  // Join the same voice channel of the author of the message
  if (message.member.voice.channel) {
    const connection = await message.member.voice.channel.join();
    if (message.content === 'ping') {
      const dispatcher = connection.play('https://cdn.glitch.com/60a14f49-0846-4bad-b84a-e5f018c2130d%2Fmsn_alert.mp3?1506640405402');
      // you can change the volume like this:
      // connection.play('https://...', { volume: 0.1 });
      dispatcher.on('start', () => {
        console.log('audio is now playing!');
      })
        .catch(err => {
          console.log('error:', err);
        });
    }
  }
})

// Always remember to handle errors appropriately!
//dispatcher.destroy();
//Leave voice channel
//connection.disconnect();
client.login(Token);

And after creating this file simply type:

node index.js

Now just join a Discord voice channel and write ping in one of the text channels and your bot will play a nice welcome tune.

This week and last I've had to dig into the product "IBM DataStage" for a workshop with a client. I used to depend on existing material and a VM based image to get an environment up and running. I decided to learn how to install the product myself and create some supplemental material.

Tip 1: Level up your Terminal with PowerLevel10k

From

As developers we spend a big chunk of our day in the terminal. So making it visually appealing is not a bad idea. There are a ton of ways to customize the look and feel of the terminal UI and you can get into this rabbit hole of custom bash scripts.

If you want a quick and easy way to make your terminal look all fancy like, then look no further than PowerLevel10k. In less than 10 minutes you can get your terminal to look from this (left) to this (right)

Tip 2: Kubernetes namespace management made EASY

From

[Deleted User]

I use namespaces in Kubernetes for testing out deployments and services. I am able to try things out in the test namespace without affecting anything in the integration namespace. The goal is to always have a working solution in the integration namespace. There are a few ways to switch between the namespaces.

The Kubernetes documentation describes a good way to do this by creating two contexts, one for test and another for integration. The user would then use the use-context command as follows

kubectl config use-context <context-name>

Another quick way to set the current namespace is by using the kubectx and kubens.

Let's take a look. Here I am currently in the default namespace:

$ kubectl get po
NAME                                READY   STATUS    RESTARTS   AGE
mariadb34-6957-47-master-0          1/1     Running   11         49d
mariadb34-6957-47-slave-0           1/1     Running   7          49d

Now use kubens to switch to the test namespace:

$ kubens test
Context "Prometeo-Kubernetes/bs8vr7fl0civct1kgnpg" modified.
Active namespace is "test".

Now let’s list the pods again:

$ kubectl get po
NAME                            READY   STATUS    RESTARTS   AGE
hello-server-5bfd595c65-ct8n9   1/1     Running   0          2d21h

It's just that simple!

This week I discovered a beta feature to save your AutoAI data model on IBM's data science platform. IBM's AutoAI experiment feature, which generates multiple models with a few clicks based on your data set, will now generate a Jupyter Notebook automatically! You can then use the AutoAI experiment results in a notebook to visualize and read your data to test, deploy and score a model!

Tip 1: Make your Bootstrap webpage mobile friendly: Trick or Treat! 👻

From

A spooky little project that was made in an hour for my son. Check it out in GIF form below. It's just some HTML and Javascript. Nothing fancy as I wanted it to be served on GitHub Pages. Click on a button to set the image source and visibility. Bootstrap was used so I could just pull in a decent looking theme easily.

One thing worth noting is that I learned how to make webpages that use Bootstrap more mobile friendly by adding this line to the header.

Tip 2: A scary case for `trash-cli` 😱

From

Mofi RahmanFollow

Go Developer, Does Container-y stuff, Collects Stickers (in no particular order)

Imagine it is Friday, 5:00 PM. You are ready to call it a day and head home. You just want delete some of the builds you did so you delete the bin folder.

Please for the love of all things good, do not run this

rm -rf /bin

Oh no! you have deleted the bin folder from your root directory!

If that is something you are scared of, you can make use of this tool. trash-cli is an rm replacement for your linux environment. You can alias trash-cli to rm and never have to worry about accidentally deleting everything off your computer.

Tip 3: Use the `watch` command to monitor your Kubernetes pods

From

[Deleted User]

One very useful command when starting with kubernetes is kubectl get po. The problem is you have to enter it over and over again when you get want to see the pod status. Fear not, there is a handy --watch flag you can pass in and this keeps the command runnings and gives you any updates. While this is an improvement, you can quickly get overwhelmed with pod change if you have a lot of pods as every change is shown as a new line. Consider this simple deployment creation using a public image:

$ kubectl create deployment hello-server --image=gcr.io/google-samples/hello-app:1.0 -n test
deployment.apps/hello-server created

Let’s check on this single pod using the --watch flag

kubectl get po -n test --watch
NAME                            READY   STATUS    RESTARTS   AGE
hello-server-5bfd595c65-pzpkz   0/1     Pending   0          0s
hello-server-5bfd595c65-pzpkz   0/1     Pending   0          0s
hello-server-5bfd595c65-pzpkz   0/1     ContainerCreating   0          0s
hello-server-5bfd595c65-pzpkz   1/1     Running             0          3s

Four lines just for this single pod! Imagine working with a namespace with a dozen pods. There are ways to ask for a single pod using labelling or adding grep after the command, but mostly people just ask for everything. Specially if you don’t know the details of the pod. To work around this verbosity of the --watch flag, I use the watch program. The watch command runs repeatedly and displays the results in a friendly manner.

Every 2.0s: kubectl get po -n test                 Upkars-MacBook-Pro.local: Fri Oct 30 17:06:44 2020
NAME                            READY   STATUS    RESTARTS   AGE
hello-server-5bfd595c65-pzpkz   1/1     Running   0          5m7s

Let’s delete the deployment using the kubectl delete deploy command. The following shows the progress of the watch screen

Every 2.0s: kubectl get po -n test                 Upkars-MacBook-Pro.local: Fri Oct 30 17:07:56 2020
NAME                            READY   STATUS    RESTARTS   AGE
hello-server-5bfd595c65-pzpkz   1/1     Running   0          6m20s

Every 2.0s: kubectl get po -n test                 Upkars-MacBook-Pro.local: Fri Oct 30 17:08:30 2020
NAME                            READY   STATUS        RESTARTS   AGE
hello-server-5bfd595c65-pzpkz   0/1     Terminating   0          6m53s

Every 2.0s: kubectl get po -n test                 Upkars-MacBook-Pro.local: Fri Oct 30 17:08:40 2020
No resources found in test namespace.

Pretty cool eh! You can install watch using brew and other package managers.

When I have started to develop a chatbot for Discord, I realized that everybody is using Node installed in their own environments. I was aiming at running a bot right away in the cloud. Instead of running your bot "natively" in your system using node, I created a Docker container that handles it all for me.

`index.js`

const Discord = require('discord.js');
const client = new Discord.Client();
const Token = process.env.token;
client.on('ready', () => {  
   console.log('Logged in as ${client.user.tag}!');
});
client.on('message', msg => {  if (msg.content === 'ping')
{
     msg.reply('Pong!');  
}});
client.login(Token);

`package.json`

{
"dependencies": {
    "discord.js": "^12.3.1"
  }
}

`Dockerfile`

FROM node:10
ENV NODE_CONTAINER_VERSION=1.0.0
# Create directory for application
WORKDIR /data/bot-app
# Install dependencies
COPY package*.json ./
RUN npm install
COPY . .
CMD [ "node", "index.js" ]

Now you can build your image (use your Docker id here - and mind the trailing dot):

docker build -t <YOUR_DOCKER_ID>/node-container .

And to start your Docker container with the Discord bot (add in your Discord token):

docker run -e token="<YOUR_TOKEN>" -d <YOUR_DOCKER_ID>/node-container

Now you can ping your bot! 🤖

Javascript: `in` vs `of`

From Nigel

This week I learned about a neat little trick when iterating through arrays in javascript. The important of in which gives you the position in the array, and of which gives you the value of the element in the array. Fun!

let myArray = ["cat", "dog", "mouse"]

for (let val in myArray) {
    console.log(val) // 0, 1, 2
}

for (let val of myArray) {
    console.log(val) // "cat", "dog", "mouse"
}

Shout out to Nick Bourdakos for showing me this one.

There's already tons of literature on this topic but it's something I learned this week. The reason why I'm doing this will come in another post ;)

Note, you'll need bash 4.0 or newer for this to work.

#!/usr/bin/env bash

declare -A dict

dict=(["fruit"]="apple" ["meat"]="chicken" ["dairy"]="cheese")

for i in "${!dict[@]}"
do
    echo "$i"="${dict[$i]}"

I've created static sites with GitHub pages before but this time was different because we decided to use Docusaurus which was open sourced by Facebook, see the Docusaurus Git Repo.

I was blown away by just how simple it was to set up and how many things were included out of the box. We were even able to embed a running instance of our application too!

Skype a Scientist

From Nigel

Volunteering and mentoring is essential to growing your career at any company. IBM emphasizes these types of activities. I recently signed up to participate with Skype a Scientist where professionals in STEM fields are connected with schools to present to students.

Yesterday was my first session. I spoke with students from Emerson Elementary School in California. I told them about supercomputers and showed them a few single board computers. They most wanted to know about Minecraft :)

Below are a few of the questions they asked:

What kind of a scientist are you?
Give us examples of experiments that you do.
Do you create video games?
Are you always on the computer?

If you're even a little bit interested I would encourage you to sign up as it was a very rewarding experience.

Managing your Node.js versions

From

Jenna RittenFollow

Jenna left Detroit to attend Dev Bootcamp San Francisco to learn full-stack web development before joining IBM as part of the Tech Re-Entry program. She advocates for underrepresented people in tech.

My FAVORITE tool for managing the various Node.js versions I have installed for different projects is Node Version Manager (nvm). It’s super simple to install and to use.

Pro-Tip: I recommend using Terminal and not iTerm since iTerm will not hold onto nvm and you’ll have to continuously re-install it.

Check out the following tutorial to quickly install and start using nvm! I’ve included the following code snippets as well. Voila!

# Install using curl
curl -sL https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh -o install_nvm.sh

# run the install script with bash
bash install_nvm.sh

# confirm that your profile is updated *
export NVM_DIR="$HOME/.nvm"
# load nvm *
  [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
# load nvm bash_completion *
  [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" 

# restart your terminal
source ~/.bash_profile

# verify it worked // should return 'nvm'
command -v nvm

# Using brew, install Node Version Manager (nvm)
brew install nvm

# run the command for next steps to finish the install
brew info nvm

Byte-Sized Tech Tips Round-Up: Week 1

Populate a Cloudant database with Python

In just a few lines I was able to use the Cloudant Python SDK to quickly seed a database with 1400 entries from a YAML file.

Pro-tip: Make sure you're using the Replay429Adapter in your client or you'll surely hit a Rate Limit Error

import yaml
from cloudant import Cloudant
from cloudant.adapters import Replay429Adapter


username = "foo"
password = "bar"
url = "baz"
client = Cloudant(username, password, url=url, connect=True,
                  adapter=Replay429Adapter(retries=10, initialBackoff=0.01))

client.connect()
db = client.create_database("repos", throw_on_exists=False)

with open("repos.yaml", 'r') as stream:
    data_loaded = yaml.safe_load(stream)

    for entry in data_loaded['repos']:
        db.create_document(entry)

This week I was had a chance to play with expo. The application we're building in React will work on Android and iOS from the same JavaScript codebase. Expo also provides access to device capabilities like camera, location, notifications. Putting it all together was the iOS simulator functions of Xcode!

Read more about using Expo with iOS in the docs.

Bang-bang

From Nigel

I'm currently taking the Red Hat System Administration I
course in preparation of the Red Hat OpenShift I: Containers & Kubernetes course. One this I learned this week was the !! Bang-bang command. The !! Bang-bang command repeats the last command. It's especially helpful with commands that you forgot to put sudo in front of. For example:

$ yum update
Loaded plugins: priorities, update-motd, upgrade-helper
You need to be root to perform this command.

$ sudo !!
sudo yum update
Loaded plugins: priorities, update-motd, upgrade-helper

API Connect Sandbox features

This week I hosted a workshop about API Connect. One thing I learned about this week was API Connect's Sandbox service. I had played with tools such as Postman before but the Sandbox service has great features such as adding collaborators and deploying your sandbox to a staging-like environment. Those really impressed me!
