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