Create EC2 instance

Please add your AWS user credentials to the inventory file:

And execute following statement:

docker run -it --rm -v $(pwd):/ansible \
ryanwalls/ansible-aws:v2.3.1.0-1 sh -c "ansible-playbook -i ./inventory ec2-basic.yml"

Multiple instances per user

• copy the id_rsa_your_name.pub key into the deploy_keys directory.
• add role execution to ec2-basic.yml like this:

  - { role: ec2_basic, key_name: 'id_rsa_joe', tags: basic}
  - { role: ec2_basic, key_name: 'id_rsa_peter', tags: basic}
  - { role: ec2_basic, key_name: 'id_rsa_julia', tags: basic}
  

SSH connection

look up the public ip in the inventory file underneath [playground] block and pass it to:

ssh -i ./deploy_keys/<key_name> <ansible_ssh_user>@<PUBLIC_IP>

Uncomment the FOR DELETION ONLY block in the inventory file and enter the correct ec2 instance id
