'host_specific_hostname_identity' is undefined

[DrMoriarty]

Hello!

I configured ansible as described in Readme file. When I run ansible-playbook -i inventory/hosts setup.yml --tags=setup-main I always get the error:

TASK [matrix-server : Determine domains to obtain certificates for (Matrix)] ***********************************************************************************************
fatal: [matrix.mobilap.ru]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: matrix.{{ hostname_identity }}: {{ host_specific_hostname_identity }}: 'host_specific_hostname_identity' is undefined\n\nThe error appears to have been in '/Volumes/ST1000/projects/WVV2/matrix-docker-ansible-deploy/roles/matrix-server/tasks/setup_ssl.yml': line 3, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Determine domains to obtain certificates for (Matrix)\n  ^ here\n"}

PLAY RECAP *****************************************************************************************************************************************************************
matrix.mobilap.ru          : ok=11   changed=0    unreachable=0    failed=1  

I double checked that my vars.yml is correct and it contains host_specific_hostname_identity variable

The only solution I have found is to add definitions of host_specific_matrix_ssl_support_email and host_specific_hostname_identity to roles/matrix-server/defaults/main.yml

Is your inventory host file (inventory/matrix.<your-domain>/vars.yml) based on the example file (examples/host-vars.yml) like the README says?

In that case, your inventory hostname file (inventory/matrix.<your-domain>/vars.yml) should already contain definitions for host_specific_matrix_ssl_support_email and host_specific_hostname_identity.

So unless you added these variables once again in roles/matrix-server/defaults/main.yml, it was showing that error?

Which version of Ansible is this and under which OS/distro?

[DrMoriarty]

Yes, I copied examples/host-vars.yml to inventory/matrix.mobilap.ru/vars.yml then I set the values of this two parameters.

The error was in every run until I set this two additional variables in roles/matrix-server/defaults/main.yml

bash-3.2$ ansible --version

Seems like the README instructions were incorrect.

They instructed you to create an inventory/matrix.<host> directory, but it actually should have been inventory/host_vars/matrix.<host> (there needs to be an extra host_vars directory level there).

Because of this, the host variables were not found and read by Ansible.

I have fixed the incorrect README instructions in edd97d3.

If you do a git pull and mv inventory/matrix.mobilap.ru inventory/host_vars/matrix.mobilap.ru you should be able to get it solved.

Thanks for reporting the problem, so we could get it fixed for everyone!
