“`bash
sudo apt-get install –only-upgrade docker-ce docker-ce-cli containerd.io
“`

In Red Hat, CentOS, or Fedora, you can upgrade Docker by running:

Refresh the package cache:

“`bash
sudo yum check-update
“`

Upgrade Docker Engine:

“`bash
sudo yum update docker-ce docker-ce-cli containerd.io
“`

Alternatively, on Fedora systems with `dnf`:

“`bash
sudo dnf upgrade docker-ce docker-ce-cli containerd.io
“`

If you installed Docker using the convenience script, you may need to rerun the script to upgrade Docker to the latest version. However, using the package manager is preferred to maintain version control and system stability.

“`

Clean up old images and containers that may no longer be needed:

“`bash
docker system prune -f
“`

Additionally, review the Docker logs to identify any warnings or errors:

“`bash
sudo journalctl -u docker.service –since “10 minutes ago”
“`

This helps ensure the upgraded Docker Engine operates as expected and that no residual issues remain from the upgrade process.

Preparing for a Docker Upgrade

Before initiating the upgrade process, it is critical to ensure that your system and Docker environment are properly prepared. This reduces the risk of service interruptions and data loss.

Begin by verifying the current Docker version and system compatibility. Confirm that your operating system meets the requirements for the newer Docker release. Additionally, review Docker’s official release notes for any breaking changes or new dependencies.

Check current Docker version: Run docker --version to identify the installed version.
