Role Variables

Currently the following variables are supported:

General

ocp_client_install_url - Required, http(s) URL to the OCP Client archive. A recipe for setting this automatically is included in the examples below.
ocp_client_install_path - Default: /usr/local/bin/. Destination directory for installed oc and kubectl binaries. This location should be in the system PATH.
ocp_client_install_tmpdir - Default: /tmp/ocp_client_install. Directory in which to download the OCP Client archive.
ocp_client_install_cleanup - Default: false. For the purposes of idempotence, the ocp_client_install_tmpdir directory is not removed by this role by default. Set this to true to cause this role to clean up the ocp_client_install_tmpdir.

Privilege Escalation

ocp_client_install_become - Default: true. If this role needs administrator privileges, then use the Ansible become functionality (based off sudo).
ocp_client_install_become_user - Default: root. If the role uses the become functionality for privilege escalation, then this is the name of the target user to change to.

Dependencies

None

Example Playbook

Directly download with absolute URL to archive

- hosts: ocp_client_install
  roles:
    - role: oasis_roles.ocp_client_install
      ocp_client_install_url: 'https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/openshift-client-linux-4.2.4.tar.gz'

Use the index_href role to automatically determine latest OCP Client archive URL:

- hosts: ocp_client_install
  vars:
    # trailing slash is important here
    ocp_installers_index_url: https://mirror.openshift.com/pub/openshift-v4/clients/ocp/latest/
    ocp_installers_index: "{{ query('url', ocp_installers_index_url) }}"
    ocp_client_install_url: >-
        {{ query('index_href', ocp_installers_index, 'client-linux',
           base_url=ocp_installers_index_url) }}
  roles:
    - oasis_roles.ocp_client_install
    - oasis_roles.index_href
