yum

The yum resource reference. This resource manages packages on Red Hat-based Linux systems using YUM (Yellowdog Updater Modified) package manager. YUM is the traditional package manager for RHEL, CentOS 7 and earlier, and other older Red Hat-based distributions.

Parameters:

• install: (array[string | object]) A list of packages to install using yum. 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 yum 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": "yum",
    "install": [
      "curl",
      "git",
      "vim",
      "gcc"
    ]
  }
]

Installing specific package versions

[
  {
    "type": "yum",
    "install": [
      "curl",
      {
        "name": "nginx",
        "version": "1.12.2-3.el7"
      },
      {
        "name": "postgresql",
        "version": "9.2.24-1.el7_5"
      }
    ]
  }
]

Skipping the update step

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

Notes:

• The yum resource requires sudo privileges to install packages. Codify will prompt for your password when needed.
• YUM is primarily for older Red Hat-based Linux distributions. For modern RHEL 8+, Fedora, Rocky Linux, and AlmaLinux systems, use the dnf resource instead, as DNF is the successor to YUM. For Debian-based systems, use the apt resource.
• Package names must match those available in your configured YUM repositories. Use yum search <package> to find available packages.
• When specifying versions, use the exact version string as shown by yum list <package>.
