matrix_mx_puppet_instagram_database_engine has been set to `postgres` (which is our new default now).
|
|
||||||
However, we've discovered an existing SQLite database in {{ matrix_mx_puppet_instagram_data_path }}/database.db.
|
|
||||||
It appears that you've been using this bridge with the SQLite engine until now.
|
|
||||||
To continue using SQLite, opt into it explicitly: add `matrix_mx_puppet_instagram_database_engine: sqlite` to your vars.yml file and re-run this same command.
|
|
||||||
Alternatively, to migrate your existing SQLite database to Postgres:
|
|
||||||
1. Stop all services (`ansible-playbook -i inventory/hosts setup.yml --tags=stop`)
|
|
||||||
2. Import the SQLite database into Postgres (`ansible-playbook -v -i inventory/hosts setup.yml --tags=import-generic-sqlite-db --extra-vars='sqlite_database_path={{ matrix_mx_puppet_instagram_data_path }}/database.db postgres_connection_string_variable_name=matrix_mx_puppet_instagram_database_connString'`)
|
|
||||||
3. Re-run the playbook (`ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`)
