 This article is only for practicing ansible and aws codecommit.
You might think this is automation drill?.

 In a real situation, codecommit repository will be created with our mouse's click and click, and ssh key and git credential by manually cause necessary codecommit repositories are very limited in most cases.

 Nonetheless, parts of this playbook yaml, such as "creating ssh keys" and "and applying that in local env" could be useful for our automation life.

 1. We should prepare aws-cli and ansible(python3) installation.

*aws cli)

oyj@controller:~$ pip3 install virtualenv --user

oyj@controller:~$ virtualenv anbawscmmit
created virtual environment in 391ms
  creator CPython3Posix(dest=/home/oyj/deploy_aws/anbawscmmit, clear=False, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/home/oyj/.local/share/virtualenv)
    added seed packages: pip==20.1.1, setuptools==47.2.0, wheel==0.34.2
  activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
oyj@controller:~$ source anbawscmmit/bin/activate

oyj@controller:~$ source anbawscmmit/bin/activate

(anbawscmmit) oyj@controller:~/ansible-aws$ pip3 install boto3

#Until now it is ok.

2. Clone github repo , create aws codecommit repository and upload below node sources.

(anbawscmmit) oyj@controller:~/ansible-aws$ ls node_auth
app.js  appspec.yml  core  package.json  package-lock.json  public  routes  scripts  views

(anbawscmmit) oyj@controller:~$ git clone

#ansible playbook. All playbook codes are commented.

#As you see below, codecommit user is "cc_user",  ssh_key_name : "codecommit_key"..and so on.

(anbawscmmit) oyj@controller:~/ansible-aws$ cat create_user_cmmitrepo_upload_nodeauth_app.yaml | head -20

#Well it works!(Apache!)

#Lastly I will delete this codecommit repo with ansible(same playbook but different options)

#With "-e "STATE=absent"" option. We could all codecommit related things all at once.

(anbawscmmit) oyj@controller:~/ansible-aws$ ansible-playbook create_user_cmmitrepo_upload_nodeauth_app.yaml -e "STATE=absent"

 With ansilbe, aws configuration could be very convenient and automatic with just one line command but lots of configuration and file works.

Thanks for reading!
