|
# This is the top level playbook for the 'k3s' role.
|
|
#
|
|
# This playbook will install k3s to one or more hosts. If there are multiple
|
|
# hosts the first inventory host will be the master node, and all others will
|
|
# be worker nodes.
|
|
#
|
|
# This playbook will only setup simple clusters with a single master node. To
|
|
# setup an HA cluster with multiple master nodes, please refer to the following
|
|
# URL and perform the cluster installation manually.
|
|
#
|
|
# * https://docs.k3s.io/installation/ha-embedded
|
|
#
|
|
# Each host should have at least 4GB of RAM and at least a 20GB disk.
|
|
#
|
|
# It is also assumed that the user running the playbook has SSH key access
|
|
# set up for the root user on the target hosts.
|
