-All the files are encrypted with ansible-vault
-You can put additional DB initialization/dump SQL instuctions to files/django.sql
-
files/postgres.pw contains password for postgres user (Postgres 9.6 container)
-
files/default.py contains secret key generated at http://www.miniwebtool.com/django-secret-key-generator/
-
files/local.py contains database connection settings for django-sample-app
-
files/Dockerfile contains instuctions to build Docker image for django-sample-app
-Test stack includes django-sample-app and postgres 9.6, just run 'ansible-playbook django.yml -i testhost --ask-vault-pass' You will be prompted for ansible-vault password for encrypted files, containers and all required packages will be installed from scratch
-No additional Ansible modules required to be installed, tested with Ansible 2.7.10 on Ubuntu 18.04
-As the result you should receive the following output log:
root@instance-1:/etc/ansible# ansible-playbook django.yml -i testhost --ask-vault-pass Vault password: [DEPRECATION WARNING]: Instead of sudo/sudo_user, use become/become_user and make sure become_method is 'sudo' (default). This feature will be removed in version 2.9. Deprecation warnings can be disabled by setting deprecation_warnings=False in ansible.cfg.
