Dependencies

There are many applications used throughout the course that need to be installed in your development environment.

Rather than have you install them all manually, I have provided

Requires Manual Install

Docker Desktop: Build and run containers

Docker Desktop is a set of applications used to develop and run containers.

Please follow the installation instructions on the website based on your system architecture.

Devbox: Portable, isolated dev environments

Devbox is a tool that leverages the Nix package manager to produce isolated development environments containing the exact set of software tools/versions you need.

Please follow the installation instructions on the website to install on your system.

Installed via DevBox

In the root of the course repo there is a devbox.json and a devbox.lock file containing the full set of dependencies (listed below).

After instaling devbox, you can simply run:

devbox shell

and devbox will use Nix package manager to install a copy of all of the required software in an isolated environment.

Note: these applications are installed in such a way that they will NOT impact other versions you may have installed already on your system.

Aliases

I suggest creating the following aliases:

k=kubectl
t=task
tl='task --list-all'

These will save you many keystrokes! If you want, you can go even further and generate hundreds of kubectl aliases.

Autocomplete:

Setting up tab completion for your shell of choice makes life much nicer:

• kubectl: https://kubernetes.io/docs/reference/kubectl/generated/kubectl_completion/
• task: https://taskfile.dev/installation/#setup-completions
