Problem with CoreOS AWS Cloudinit

Question

I am trying to configure EC2 instances using stable AMI CoreOS with some configurable cloud-init configurations, but with some problems.

#cloud-config
coreos:
  etcd:
    discovery: https://discovery.etcd.io/5996f1b49fd642c5d1bc2f62cbff2fba
    addr: $private_ipv4:4001
    peer-addr: $private_ipv4:7001
  units:
    - name: etcd.service
      command: start
    - name: fleet.service
      command: start
write_files:
  - path: /etc/fleet/fleet.conf
    content: |
      public_ip="$private_ipv4"
      metadata="elastic_ip=true,public_ip=$public_ipv4"

Cloud-config above works fine, but as soon as I use below cloud-config

#cloud-config
coreos:
  etcd:
    discovery: https://discovery.etcd.io/5996f1b49fd642c5d1bc2f62cbff2fba
    addr: $private_ipv4:4001
    peer-addr: $private_ipv4:7001
  units:
    - name: etcd.service
      command: start
    - name: fleet.service
      command: start
users:
  - name: core
    coreos-ssh-import-github: oba11
write_files:
  - path: /etc/fleet/fleet.conf
    content: |
      public_ip="$private_ipv4"
      metadata="elastic_ip=true,public_ip=$public_ipv4"

or

#cloud-config
coreos:
  etcd:
    discovery: https://discovery.etcd.io/5996f1b49fd642c5d1bc2f62cbff2fba
    addr: $private_ipv4:4001
    peer-addr: $private_ipv4:7001
  units:
    - name: etcd.service
      command: start
    - name: fleet.service
      command: start
users:
  - name: oba11
    groups:
      - sudo
      - docker
    coreos-ssh-import-github: oba11
write_files:
  - path: /etc/fleet/fleet.conf
    content: |
      public_ip="$private_ipv4"
      metadata="elastic_ip=true,public_ip=$public_ipv4"

I can no longer use SSH for coreos instances as the "primary" user using my aws key pair or private key and created a custom "oba11" with my private key. I also tried alpha AMI, but the same problem. I do not know that I am doing something wrong.

Thank you very much for your help.
