private repo is getting cloned via ansible playbook but private gem are not getting installed

I am using ansible for configuration management. I am cloning the private repo after copying the public and private key pair file to the remote server. The cloning is working fine but when I ran bundle install, getting error of public key permission denied.

Ansible playbook

---
- hosts: launched
  sudo: yes
  remote_user: ubuntu
  key_file: /home/ubuntu/.ssh/id_rsa
  tasks:
  - name: update apt
    apt: update_cache=yes

  - name: ensure public key and public one are present
    sudo: yes
    copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600
    with_items:
      - id_rsa.pub

  - name: ensure private key and public one are present
    sudo: yes
    copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600
    with_items:
      - id_rsa

  - name: Deploy site files from Github repository
#    sudo: yes
    git: [email protected]:xyz/abc.git dest=/home/{{deploy_user}}/{{app_name}} key_file=/home/ubuntu/.ssh/id_rsa accept_hostkey=yes force=yes version=release
  - name: config database.yml
    template: src=database.yml.j2 dest={{ deploy_directory}}/config/database.yml

  - name: bundle install
    command: bundle install chdir={{ deploy_directory }}

  - name: sidekiq initializer
    command: bundle exec sidekiq -C ./config/sidekiq.yml chdir={{deploy_directory}}

  - name: migrate create
    command: rake db:create RAILS_ENV="production" chdir={{ deploy_directory }}

  - name: migrate migrate
    command: rake db:migrate RAILS_ENV="production" chdir={{ deploy_directory }}

The Gemfile uses private gems via ssh url of gitub. Thus, while running the bundle install through playbook, getting the following error.

failed: [X.X.X.X] => {"changed": true, "cmd": ["bundle", "install"], "delta": "0:00:05.788387", "end": "2015-11-03 06:39:43.671879", "rc": 11, "start": "2015-11-03 06:39:37.883492", "warnings": []}
stderr: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights.

The key I added to remote server also have access to private gem but somehow it is denying the permission.

I personally tried cloning the repo by ssh into the remote server but could not access the either repo(main repo and gem repo), though keys are being copied to ~/.ssh/ diretory of remote server.

youll notice that in the SSH output you have 

 Trying private key: /home/ubuntu/.ssh/id_rsa debug1: could not open
 key file '/home/ubuntu/.ssh/id_rsa': Permission denied debug1: Trying
 private key: /home/ubuntu/.ssh/id_dsa debug3: no such identity:
 /home/ubuntu/.ssh/id_dsa: No such file or directory debug1: Trying
 private key: /home/ubuntu/.ssh/id_ecdsa debug3: no such identity:
 /home/ubuntu/.ssh/id_ecdsa: No such file or directory debug1: Trying
 private key: /home/ubuntu/.ssh/id_ed25519 debug3: no such identity:
 /home/ubuntu/.ssh/id_ed25519: No such file or directory

the first line says that current user doesn't have permission for id_rsa.

it seems you use sudo to copy the key which might set the ownership of the file to root instead of ubuntu.

change:

copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600

to:

copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600 owner=ubuntu

which according to ansible docs will be the user the file should be owned by

also you should put both files (id_rsa and id_rsa.pub) in the same with items so it will run them in a loop

like:

 - name: ensure public key and public one are present
    sudo: yes
    copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600
    with_items:
      - id_rsa.pub
      - id_rsa
