Ansible Role: crio

Install CRI-O on a RHEL/CentOS or Debian/Ubuntu server.

This role will do the following.

• Load Kernel module.
• Configure Kernel parameters.
• Install CRI-O.
• Configure CRI-O.

Requirements

There are no special requirements for this role.

Role Variables

crio_version: "1.24"

Specifies the version of CRI-O to install. You can specify either "X.Y" or "X.Y.Z" format. Cannot include *.

crio_sysctl_filename: "/etc/sysctl.d/99-kubernetes-cri.conf"

Specifies the filename to save the Kernel parameter settings.

crio_os: Debian_10

Specifies the OS of the host on which to install.

The value to specify for each OS is the value of $OS as described in cri-o installation instructions, but as of May 2022, the linked information seems to be out of date. From my research, the currently valid OS specification is as follows.

Operating system	$OS (crio_os)
CentOS 7	CentOS_7
CentOS 8	CentOS_8
CentOS 8 Stream	CentOS_8_Stream
Debian 10	Debian_10
Debian 11	Debian_11
Fedora 35	Fedora_35
Fedora Rawhide	Fedora_Rawhide
Raspbian 10	Raspbian_10
Raspbian 11	Raspbian_11
Ubuntu 18.04	xUbuntu_18.04
Ubuntu 20.04	xUbuntu_20.04
Ubuntu 21.10	xUbuntu_21.10
Ubuntu 22.04	xUbuntu_22.04

Note that the valid OS depends on the version of CRI-O. The available OS for each version can be found at openSUSE Download. Select the version of CRI-O you wish to install from openSUSE Download and check the directory name displayed.

If your OS has files under vars/, crio_os will be set automatically and you do not need to specify it.

crio_version_url: '1.24'

This parameter is used as part of the URL of the CRI-O repository. It may be in the form X.Y or X.Y:/X.Y.Z. (e.g., 1.24 or 1.24:/1.24.0)

You don't need to specify the value of crio_version, since it is automatically set from the value of crio_version.

crio_long_version: '1.24'

This parameter specifies the version of CRI-O in long form. It is specified in either X.Y or X.Y:X.Y.Z format. (e.g., 1.24 or 1.24:1.24.0) The format is similar to crio_version_url, but with or without /.

It is automatically set from the value of crio_version, so you don't need to specify it.

crio_conf: {}

This parameter specifies the contents of crio.conf. See https://github.com/cri-o/cri-o/blob/main/docs/crio.conf.5.md for parameters that can be specified in crio.conf.

crio_conf can be specified as follows:

crio_conf:
  "table":
    option: value
  "table.subtable1":
    option: value
  "table.subtable2":
    option: value

In this case, crio.conf outputs the following:

[table]
option = value

[table.subtable1]
option = value

[table.subtable2]
option = value

See crio_conf.yml.example for a more realistic specificatioin.

Role Tags

crio-repo-key

The crio-repo-key tag can be used to update keys used in the CRI-O apt repository.

It does not perform tasks such as updating the apt repository cache, updating CRI-O packages, or changing settings. Use this function only for updating keys, such as when a key has expired.

Dependencies

None.
