# dev-build.sh
|
|
#
|
|
# Convenience script for developing kops AND nodeup.
|
|
#
|
|
# This script (by design) will handle building a full kops cluster in AWS,
|
|
# with a custom version of the nodeup, protokube and dnscontroller.
|
|
#
|
|
# This script and Makefile uses aws client
|
|
# https://aws.amazon.com/cli/
|
|
# and make sure you `aws configure`
|
|
#
|
|
# # Example usage
|
|
#
|
|
# KOPS_STATE_STORE="s3://my-dev-s3-state" \
|
|
# CLUSTER_NAME="fullcluster.name.mydomain.io" \
|
|
# NODEUP_BUCKET="s3-devel-bucket-name-store-nodeup" \
|
|
# IMAGE="kope.io/k8s-1.6-debian-jessie-amd64-hvm-ebs-2017-05-02" \
|
|
# ./dev-build.sh
|
|
#
|
|
# # TLDR;
|
|
# 1. setup dns in route53
|
|
# 2. create s3 buckets - state store and nodeup bucket
|
|
# 3. set zones appropriately, you need 3 zones in a region for HA
|
|
# 4. run script
|
|
# 5. find bastion to ssh into (look in ELBs)
|
|
# 6. use ssh-agent and ssh -A
|
|
# 7. your pem will be the access token
|
|
# 8. user is admin, and the default is debian
|
|
