Create EC2 Instance by Ansible Failed with ec2: error: unrecognized arguments:

Question

I am newbie to Ansible and follow this tutorial to create a security group and an ec2 instance. The security group is created successfully, but creating ec2 instance is failed by ec2:

error: unrecognized arguments: /home/ec2-user/.ansible/tmp/ansible-tmp-14244....

I did set up aws credentials and asnsible variables properly as below

# AWS Credentials
export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=xxx

# EC2 Environment Variables
export ANSIBLE_HOSTS=/etc/ansible/ec2.py
export EC2_INI_PATH=/etc/ansible/ec2.ini

The files and output are showed as follow. Any ideas for this issue? Thanks for your Help!

$ cat group_vars/all
# Variables listed here are applicable to all host groups 
key_name: sobrr-staging.pem
aws_region: cn-north-1
ami_id: ami-9e0c9ea7
instance_type: m1.small

$ cat basic-create.yml

The key_name parameter in Ansible ec2 module refers to the ssh public key you uploaded or created(if you want to reuse the previous key) in your AWS account. You may want to verify it matches the name you specified in the AWS account.

My guess is that the key name in you AWS account is sobrr-staging, not sobrr-staging.pem

Try use sobrr-staging and see how that goes.
