dnf

The dnf resource reference. This resource manages packages on modern Red Hat-based Linux systems using DNF (Dandified YUM) package manager. DNF is the next-generation version of YUM and is the default package manager for Fedora, RHEL 8+, CentOS 8+, Rocky Linux, and AlmaLinux.

Parameters:

• install: (array[string | object]) A list of packages to install using dnf. Each package can be specified as:

  • A simple string with the package name (e.g., "curl")
  • An object with name and optional version fields for version-specific installations

• update: (boolean) Whether to run dnf check-update before installing packages to refresh the package metadata. Defaults to true. Set to false to skip the update step if you've recently updated your package lists.

Example usage:

Installing packages with simple names

[
  {
    "type": "dnf",
    "install": [
      "curl",
      "git",
      "vim",
      "gcc"
    ]
  }
]

Installing specific package versions

[
  {
    "type": "dnf",
    "install": [
      "curl",
      {
        "name": "nginx",
        "version": "1.20.1-1.el9"
      },
      {
        "name": "postgresql",
        "version": "13.7-1.el9"
      }
    ]
  }
]

Skipping the update step

[
  {
    "type": "dnf",
    "install": [
      "jq",
      "htop"
    ],
    "update": false
  }
]

Notes:

• The dnf resource requires sudo privileges to install packages. Codify will prompt for your password when needed.
• DNF is only available on modern Red Hat-based Linux distributions. For older RHEL/CentOS systems (version 7 and below), use the yum resource instead. For Debian-based systems, use the apt resource.
• DNF is faster and more efficient than YUM, with better dependency resolution and lower memory usage.
• Package names must match those available in your configured DNF repositories. Use dnf search <package> to find available packages.
• When specifying versions, use the exact version string as shown by dnf list <package>.
