The install option explicitly installs only Python 3.
The pip/pip3 Python package manager and development headers are included.

To use the pip package manager, a typical usage will be pip3 install -U <module>.

Docker

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.

Docker logs can be accessed using next command:

journalctl -u docker -u containerd

The location of the Docker configuration files:

  • Docker: /etc/docker/daemon.json
  • containerd: /etc/containerd/config.toml

Docker Compose

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.

The tool is available soon after the installation. In case you need to upgrade it, here is the command:

sudo pip3 install docker-compose --upgrade

Portainer

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 9002:

Update to latest version:

dietpi-software reinstall 185

  1. 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 ↩
