# This is an example of a ansible playbook to install Tendrl, automating steps
# from upstream *Tendrl Package Installation Reference*. You need to review it
# and either tweak it or use it as a starting point before installing
# Tendrl.

# The playbook expects inventory file with the following groups:
#
# * tendrl-server: a single machine where Tendrl Server (management console) is
#                  installed
# * gluster-servers: gluster storage servers (machines with bricks)
#
# Note that this is just an example which holds for this playbook, tendrl roles
# doesn't care how you group your servers in ansible inventory.

#
# Validation of prerequisities for Tendrl, doesn't modify machines in any way.
#

- include: prechecks.yml

#
# Workarounds required to run before the installation.
#

- include: workaround.disable-firewall.yml

#
# Run yum update.

    # You need to specify fqdn where etcd will be listening, either by
    # value based on prior knowledge of your infrastructure:
    # etcd_fqdn: 'tendrl.example.com'
    # or using ansible facts: fqdn of tendrl-server as detected by ansible:

    # listening, to configure etcd itself.
