Dnf Operations

Manage dnf packages and repositories. Note that dnf package names are case-sensitive.

dnf.key

Add dnf gpg keys with rpm.

dnf.key(src)
  • key: filename or URL

Note:

always returns one command, not state checking

Example:

linux_id = host.fact.linux_distribution['release_meta'].get('ID')
dnf.key(
    name='Add the Docker CentOS gpg key',
    src='https://download.docker.com/linux/{}/gpg'.format(linux_id),
)

dnf.packages

Install/remove/update dnf packages & updates.

dnf.packages(
    packages=None, present=True, latest=False, update=False, clean=False, nobest=False,
    extra_install_args=None, extra_uninstall_args=None,
)
  • packages: list of packages to ensure

  • present: whether the packages should be installed

  • latest: whether to upgrade packages without a specified version

  • update: run dnf update

  • clean: run dnf clean

  • nobest: add the no best option to install

  • extra_install_args: additional arguments to the dnf install command

  • extra_uninstall_args: additional arguments to the dnf uninstall command

Versions:

Package versions can be pinned as follows: <pkg>=<version>

Examples:

# Update package list and install packages
dnf.packages(
    name='Install Vim and Vim enhanced',
    packages=['vim-enhanced', 'vim'],
    update=True,
)

# Install the latest versions of packages (always check)
dnf.packages(
    name='Install latest Vim',
    packages=['vim'],
    latest=True,
)

dnf.repo

Add/remove/update dnf repositories.

dnf.repo(
    src, present=True, baseurl=None, description=None, enabled=True, gpgcheck=True,
    gpgkey=None,
)
  • name: URL or name for the .repo file

  • present: whether the .repo file should be present

  • baseurl: the baseurl of the repo (if name is not a URL)

  • description: optional verbose description

  • enabled: whether this repo is enabled

  • gpgcheck: whether set gpgcheck=1

  • gpgkey: the URL to the gpg key for this repo

Baseurl/description/gpgcheck/gpgkey:

These are only valid when name is a filename (ie not a URL). This is for manual construction of repository files. Use a URL to download and install remote repository files.

Examples:

# Download a repository file
dnf.rpm(
    name='Install Docker-CE repo via URL',
    src='https://download.docker.com/linux/centos/docker-ce.repo',
)

# Create the repository file from baseurl/etc
dnf.repo(
    name='Add the Docker CentOS repo',
    src='DockerCE',
    baseurl='https://download.docker.com/linux/centos/7/$basearch/stable',
)

dnf.rpm

Add/remove .rpm file packages.

dnf.rpm(src, present=True)
  • src: filename or URL of the .rpm package

  • present: whether ore not the package should exist on the system

URL sources with present=False:

If the .rpm file isn’t downloaded, pyinfra can’t remove any existing package as the file won’t exist until mid-deploy.

Example:

dnf.rpm(
   name='Install EPEL rpm to enable EPEL repo',
   src='https://dl.fedoraproject.org/pub/epel/epel-release-latest-'
   '{{  host.fact.linux_distribution.major }}.noarch.rpm',
)

dnf.update

Updates all dnf packages.

dnf.update()
