# NOTES
|
|
# This script performs etcd upgrade based on the following environmental
|
|
# variables:
|
|
# TARGET_STORAGE - API of etcd to be used (supported: 'etcd2', 'etcd3')
|
|
# TARGET_VERSION - etcd release to be used (supported: '2.2.1', '2.3.7', '3.0.17', '3.1.12', '3.2.18')
|
|
# DATA_DIRECTORY - directory with etcd data
|
|
#
|
|
# The current etcd version and storage format is detected based on the
|
|
# contents of "${DATA_DIRECTORY}/version.txt" file (if the file doesn't
|
|
# exist, we default it to "2.2.1/etcd2".
|
|
#
|
|
# The update workflow support the following upgrade steps:
|
|
# - 2.2.1/etcd2 -> 2.3.7/etcd2
|
|
# - 2.3.7/etcd2 -> 3.0.17/etcd2
|
|
# - 3.0.17/etcd3 -> 3.1.12/etcd3
|
|
# - 3.1.12/etcd3 -> 3.2.18/etcd3
|
|
#
|
|
# NOTE: The releases supported in this script has to match release binaries
|
|
# present in the etcd image (to make this script work correctly).
|
|
#
|
|
# Based on the current etcd version and storage format we detect what
|
|
# upgrade step from this should be done to get reach target configuration
