k8-terraform

This projects creates with autoscaling etcd, master and worker with 3 node etcd and master clusters.

How to create cluster

export aws keys

export AWS_ACCESS_KEY_ID='xxxxxxxxxxxxxxxxxxxx'

export AWS_SECRET_ACCESS_KEY='xxxxxxxxxxxxxxxxxxxxxxxxxxxx'

check what resources would be created:

make plan

create resources:

make apply

###Issues Observed

• flannel needs to point to remote etcd since etcd is seperated from master.
• master ELB should listed on TCP 443 instead of HTTPS
• use --leader-elect option to make sure one instance of schedular and controller manager is available at once.
