Host unreachable?

I’m trying to deploy to EC2 with Trellis.

I have followed the guides the best I can and everytime I run ansible-playbook server.yml -e env=production it spits out and SSH error.

The IP is correct in the hosts file and I can SSH into the server fine with terminal.

group_vars/all/users.yml

admin_user: ubuntu

# Also define 'vault_users' (`group_vars/staging/vault.yml`, `group_vars/production/vault.yml`)
users:
  - name: "{{ web_user }}"
    groups:
      - "{{ web_group }}"
    keys:
      - "{{ lookup('file', '~/.ssh/key.pem') }}"
      # - https://github.com/username.keys
  - name: "{{ admin_user }}"
    groups:
      - sudo
    keys:
      - "{{ lookup('file', '~/.ssh/key.pem') }}"
      # - https://github.com/username.keys

web_user: web
web_group: www-data
web_sudoers:
  - "/usr/sbin/service php7.2-fpm *"

What am I doing wrong?

Solved.

For anyone else encountering this issue, use ~/.ssh/id_rsa.pub for both ssh paths in group_vars/all/users.yml

Then, add your key to your keychain with ssh-add -K ~/.ssh/id_rsa.pub
