Manage containers in Fedora 35

Containers allow developers to package applications along with dependencies and run them anywhere. Containers allow you to separate core OS updates from application updates. You can also test and deploy different versions of applications. The Fedora project team provides Fedora IoT and Fedora CoreOS that provide reliable support for container-focused workflows.

Fedora CoreOS

According to the Fedora project team, Fedora CoreOS is an automatically updating, minimal operating system designed for running containerized workloads securely and at scale. The OS allows you to run applications as containers. You can also install extra packages with the rpm-ostree tool, which atomically layers changes on top of the base image.
You can download Fedora CoreOS from its official download page.


Docker is an excellent platform for developers to develop, ship, and run applications in containers. With Docker, you can quickly assemble applications and get your code tested and deployed into production as fast as possible. You can install the docker-ce package using the Docker repository in Fedora 35 with the following steps.
Install the dnf-plugins-core package:

$ sudo dnf install dnf-plugins-core

Add the docker-ce repository:

$ sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

Install the docker engine:

$ sudo dnf install docker-ce docker-ce-cli containerd.io

Start the Docker service:

$ sudo systemctl start docker

Learn more about Docker installation tips and tricks from Fedora’s documentation on getting started with Docker.
You can also check out Docker Compose, a tool for orchestrating several containers.


Podman is a daemon-less container engine for developing, managing, and running OCI Containers in root or rootless mode. It is an alternative to Docker, but the podman container engine is lightweight. You can install it using the following command.

$ sudo dnf install podman

You can also use Podman Compose to manage and orchestrate several containers.

Development environments

Collaboration is an essential aspect of software development, and Fedora provides several packages and IDEs that will enable you to collaborate with your team.


An integrated development environment [IDE] aids developers in every step of the software development cycle. A choice IDE might depend on a programming language, the platform you use, or resources available. Fedora provides several IDE packages such as Eclipse, Sublime-text, Microsoft Visual Studio, Atom text editor, and many more. Every developer has a favorite IDE.

Eclipse IDE

Eclipse is a full-featured, multi-language IDE to manage your software development lifecycle. You can quickly start a new project, work on existing projects, or monitor and optimize applications. Moreover, you can also write elegant documentation, interact with other issue tracking systems or CI from inside the Eclipse IDE.

Install the Eclipse package:

$ sudo dnf install eclipse
Arduino IDE

Arduino is a popular and reliable hardware platform. Unfortunately, you can not run the Fedora OS on Arduino boards. However, you can use Fedora for developing applications and projects for Arduino.
You can install the graphical Arduino IDE with the following command:

$ sudo dnf install arduino

Vagrant is one of the must-have tools for developers. It allows you to create reproducible and portable development environments. It works on top of some virtualization or containerization technologies like VirtualBox, Docker, and libvirt.

Vagrant with VirtualBox
To use Vagrant with VirtualBox in Fedora 35, install the vagrant package with the following command:

$ sudo dnf install vagrant

Note that Vagrant comes with in-built support for VirtualBox. However, you need to install VirtualBox separately as it is not part of Fedora packages.

Vagrant with Docker
To use Vagrant with Docker, install the vagrant and docker packages with the following command:

$ sudo dnf install vagrant docker

Start docker service:

$ sudo systemctl start docker

Note that Vagrant comes with built-in support, and you can use Docker both as a provider and as a provisioner.

Package deploy and distribute applications

The joy of a developer is deploying and distributing software, and it’s even more enthusiastic when the software is open source. Fedora 35 provides a great platform and tools to package, deploy and distribute software. Some advantages of packaging include:

  • Code, data, config files, and post-installations scripts are bundled together.
  • You can sign packages that ensure that users can verify that the package was not altered.
  • It allows easy installation, upgrade, or removal of apps.
  • You can standardize installation paths.

RPM Packaging

RPM packaging allows you to package applications and ship them to RPM-based systems.
Run the following command to install and set up the fedora packager.

$ sudo dnf install fedora-packager rpmdevtools gcc
$ rpmdev-setuptree

Learn more from the official RPM documentation.

Copr Build Service

Copr is an easy-to-use automatic build service that builds applications as an RPM and provides you with a DNF/Yum package repository as its output. Therefore, you must have a source RPM (from RPM packaging) before starting using the Copr service. Note that you can only use Copr for FOSS (Free Open Source Software) projects.


OpenShift Origin is a distribution of Kubernetes that can come in handy for developers to manage continuous application development and multi-tenant deployments. It adds developer tools on top of Kubernetes to enable rapid development, easy deployment, scaling, and long-term lifecycle maintenance for any size of your team.

Wrapping up

Fedora editions provide an extensive set of tools and packages. With its “Freedom” philosophy, a software developer is spoilt for choices for packages, development IDEs, virtualization, containerization tools, or deployment tools. The article introduces some of the tools I use for developing, packaging, and deploying applications.
