# the fix is upstream move back to the upstream easyrsa. This is cached in GCS
|
|
# but is originally taken from:
|
|
# https://github.com/brendandburns/easy-rsa/archive/master.tar.gz
|
|
#
|

# To update, do the following:
|
|
# curl -o easy-rsa.tar.gz https://github.com/brendandburns/easy-rsa/archive/master.tar.gz
|
|
# gsutil cp easy-rsa.tar.gz gs://kubernetes-release/easy-rsa/easy-rsa.tar.gz
|

|

|
|
# distributed.
|

|

# pre-pushed in cases where an outgoing connection is not allowed.
