How do I run DietPi-Software and install optimised software items?
To install any of the DietPi optimised software items listed below run from the command line:
Choose Browse Software and select one or more items. Finally select
DietPi will do all the necessary steps to install and start these software items.

Python is a text based interpreted programming language with object oriented programming options for general purpose applications.
You can find Python everywhere in the world of computer programming. For example, Python is the foundation of some of the world’s most popular websites 3, including Reddit, Dropbox, and YouTube, to name a few. The Python web framework Django powers both Instagram and Pinterest.
Currently, Python is 3rd most popular of programming language 4.
The install option explicitly installs only Python 3.
pip3 Python package manager and development headers are included. To use the
pip package manager, a typical usage will be
pip3 install -U <module>.
There are many Python IDE packages available. Following is a short list of well known and widely good accepted IDE packages (alphabetical order):

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

Go is a compiled, fast and high-performance language intended to be simple and is designed to be easy to read and understand. Go was created at Google by Rob Pike, Robert Griesemer, and Ken Thompson, and it first appeared in Nov 2009.
Go is used by some of the big organizations such as Google, BBC, Uber, Soundcloud, Twitch, Medium, Daily Motion2. Uber has reported better throughput, high performance, latency, and uptime. BBC, the house name in broadcasting the world news, uses it for backend, including crawlers and web scrapers. The build and deployment system of Soundcloud is in Go.
To edit the code you can use an editor of your choice, or use VSCodium. The Go extension available in VSCodium provides rich language support for the Go programming language.
Just to have a taste of it, you could run some commands in Go playground
Checkout also the official tutorial Get started with Go.
Some common Go commands are:
go version: Prints the installed Go version
go env: Prints the Go internal environment variables (e.g. GOPATH). Can also be used e.g. like
$(go env GOPATH)/bin
go mod tidy <MODULNAME>: Generate a Go module
go help: Start the Go internal help in general, details for commands e.g. via
go help build
/usr/local/go: This is the place where the Go development tools is installed.
When installing packages via
go install, they are installed into the users home directory
~/goby default. A custom path can be set via the
GOPATHenvironment variable. To also load binaries of compiled Go packages into your
PATH, something like this can be done:
cat << '_EOF_' >> ~/.bashrc export GOPATH=/path/to/go export PATH="$PATH:$GOPATH/bin" _EOF_

In 2013, Docker introduced containers. These are a standardized unit of software that allows developers to isolate their application from the environment. Docker is de facto standard to build and share containerized apps - from single board computers (SBC), to desktop or cloud.
A Docker container image is a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries and settings.
The Docker configuration files are located at:
Since Docker is installed via APT packages, it can be updated by running the following commands:
apt update apt install docker-ce containerd.io docker-ce-cli
Docker logs can be accessed using next command:
journalctl -u docker -u containerd

Docker Compose is a Docker tool used to define and run multi-container applications. With Compose, you use a
YAML file to create and configure your application’s services from this configuration file.
docker-compose is an excellent tool for development, testing, continuous integration (CI) workflows, and staging environments.

Portainer simplifies your Docker container management via Portainer web interface. It enables faster deploy of the applications and it gives real time visibility.
The web interface is accessible via port 90021:

VSCodium is a FLOSS version of Microsoft’s Visual Studio code, built directly from the source on GitHub, without branding, tracking, or telemetry.
VSCodium is installed as APT package, hence you can update it by running the following commands:
apt update apt install codium
Documentation (Visual Studio Code): https://code.visualstudio.com/docs
Documentation (VSCodium): https://github.com/VSCodium/vscodium/blob/master/DOCS.md

Logitech Media Server already listened to port
9000, and this is why Portainer has been configured to start using port
9002. For more details on the implementation Portainer in DietPi see the GitHub task: MichaIng/DietPi!3933 ↩
