Overview Versions Insights

ansible-packages

Ansible role to install packages on a host

Ansible requirements

Ansible version

Minimum required ansible version is 2.0.

Ansible role dependencies

None.

Installation

Install with Ansible Galaxy

ansible-galaxy install archf.packages

Basic usage is:

- hosts: all
  roles:
    - role: archf.packages

Install with git

If you do not want a global installation, clone it into your roles_path.

git clone [email protected]:archf/ansible-packages.git /path/to/roles_path

But I often add it as a submdule in a given playbook_dir repository.

git submodule add [email protected]:archf/ansible-packages.git <playbook_dir>/roles/packages

As the role is not managed by Ansible Galaxy, you do not have to specify the github user account.

Basic usage is:

- hosts: all
  roles:
  - role: packages

User guide

Introduction

Ansible role to perform:

/etc/sudoers adjustement
- disable requiretty to allow enabling ansible pipelining (faster execution)
- disable always_set_home (allow running sudo -E and avoids sudo make install issues)
- prepend /usr/local/bin to secure_path to allow running priviledged compiled programs
grub templating
install default packages
configure repositories (currently only yum repos)
configure yum or dnf repository
- apply centos6 quirks (yum ipv6 issues)
disable selinux on rhel
add mounts in the fstree

A lot of things are hardcoded for now.

Usage

Adding mounts to fstab

This is using the Ansible mount module.

mounts:
  - dev: '/dev/mapper/data_vg-home_lv'
    path: '/media/home_lv'
    state: mounted
    fstype: ext4
    opts: 'defaults,acl'
    group: users
    passno: X # defaults to 2
    dump: Y # defaults to 1

Configure Repos on RedHat and derivatives

This structure allows you to group repos on a per file basis.

packages_repos:
- file: base
  repos:
    - name: base
      baseurl: "http://<your host>/centos/$releasever/os/$basearch"

    - name: updates
      baseurl: "http://<your host>/centos/$releasever/updates/$basearch"

    - name: extras
      baseurl: "http://<your host>/centos/$releasever/extras/$basearch"

    - name: contrib
      baseurl: "http://<your host>/centos/$releasever/contrib/$basearch"

    - name: centosplus
      baseurl: "http://<your host>/centos/$releasever/centosplus/$basearch"

- file: epel
  repos:
    - name: epel
      baseurl: "http://<your host>/epel/$releasever/$basearch"

Role Variables

Variables are divided in three types.

The default vars section shows you which variables you may override in your ansible inventory. As a matter of fact, all variables should be defined there for explicitness, ease of documentation as well as overall role manageability.

The mandatory variables section contains variables that for several reasons do not fit into the default variables. As name implies, they must absolutely be defined in the inventory or else the role will fail. It is a good thing to avoid reach for these as much as possible and/or design the role with clear behavior when they're undefined.

The context variables are shown in section below hint you on how runtime context may affects role execution.

Default vars

Role default variables from defaults/main.yml.

# Packages installation behavior.
packages_state: latest

# Selinux state.
packages_selinux_state: disabled

# List of grub boot options assigned to GRUB_CMDLINE_LINUX_DEFAULT.
# Many distribution defaults to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash".
packages_grub_cmdline_linux_default:
  - quiet
  - splash

# List of boot option a assigned both to normal and recovery entry of each
# kernel.
packages_grub_cmdline_linux: []

Mandatory variables

None.

Context variables

Those variables from vars/*.{yml,json} are loaded dynamically during task runtime using the include_vars module.
