Hi, I am currently migrating from a classical two container setup (separated web_only and data containers) to a setup where the database is hosted on a central database server (not inside a docker container). The central database was created from the dump.sql which is part of the backup file. The docker compose web_only.yaml uses connect to central postgres database DISCOURSE_DB_SOCKET: ‘’ DISCOURSE_DB_USERNAME: discourse DISCOURSE_DB_PASSWORD: xxxx DISCOURSE_DB_HOST: 10.10.10.xx DISCOURSE_DB_NAME: discourse During the build of web_only I get the following error: FAILED -------------------- Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return # Location of failure: /usr/local/lib/ruby/gems/3.2.0/gems/pups-1.2.1/lib/pups/exec_command.rb:132:in `spawn' exec failed with the params {"cd"=>"$home", "hook"=>"db_migrate", "cmd"=>["su discourse -c 'bundle exec rake db:migrate'"]} bootstrap failed with exit code 1 ** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one. The database host is accessible with these data. Any ideas whats happening here? The same build with the standard database container finishes successfully.

[תמונה] Thommie Rother: permission denied for table site_settings OK, as always, it was a “layer 8 problem” :smiling_face_with_tear: I already had a discourse database in the postgres but the discourse user/role had not all required privileges on it. And I did miss some major “behavioural” differences between mariadb and postgres … Now I re-created all: user, database, permissions for the user/role (including ALTER DEFAULT PRIVILEGES FOR ROLE discourse IN SCHEMA public GRANT ALL ON TABLES TO “discourse”; to match tables created by this user in the future) The build finished and the instance runs fine with the remote postgres server, so its ready for importing the backup from the older instance.

Are you sure that the remote database is available from the server? It looks like it’s not. Can you telnet to the database port from the web server machine?

Hi Jay, I followed the thread of Falco at Configure Discourse to use a separate PostgreSQL server The database server is available from the VM: root@docker2:/var/discourse# pg_isready -d discourse -h 10.10.10.18 -p 5432 -U discourse 10.10.10.18:5432 - Verbindungen werden angenommen (connections are accepted) The DB name, user and password in web_only.yml are also correct. The build error is FAILED -------------------- Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' failed with return # Location of failure: /usr/local/lib/ruby/gems/3.2.0/gems/pups-1.2.1/lib/pups/exec_command.rb:132:in `spawn' exec failed with the params {"cd"=>"$home", "hook"=>"db_migrate", "cmd"=>["su discourse -c 'bundle exec rake db:migra te'"]} bootstrap failed with exit code 1 I am not a ruby expert, so I would need some help with the debugging starting from the error which appears here. Bye, Thommie

Can you [תמונה] Thommie Rother: please scroll up and look for earlier error messages, there may be more than one. ? The exact error message in the backtrace will tell us exactly what is the problem :smile: [תמונה] Thommie Rother: I am currently migrating from a classical two container setup (separated web_only and data containers) to a setup where the database is hosted on a central database server (not inside a docker container). Is your plan to ditch the data container?

[תמונה] Thommie Rother: DISCOURSE_DB_SOCKET: ‘’ I wonder if having this set to a blank value rather than unset will cause problems. In any case, please post the complete output.

the complete build log after ./launcher rebuild web_only web_only_build.zip (9.4 KB) the yaml web_only.zip (2.4 KB) Concerning the DISCOURSE_DB_SOCKET: ‘’: as we use a remote connection, I would guess that the socket value is not relevant in both cases (dockered data or remote data)

The error was farther up in the build log: … docker_manager is already at latest compatible version wp-discourse is already at latest compatible version I, [2023-11-10T21:08:17.388213 #1] INFO -- : > cd /var/www/discourse && su discourse -c 'bundle exec rake db:migrate' Plugin name is 'discourse-topic-voting', but plugin directory is named 'discourse-voting' rake aborted! ActiveRecord::StatementInvalid: PG::InsufficientPrivilege: ERROR: permission denied for table users (ActiveRecord::StatementInvalid) So good news! It’s connecting fine, it’s that DB permissions need adjusting.

Hmmmm, strange, the discourse database user has postgres=# GRANT ALL ON DATABASE discourse TO discourse; on the central postgres server. Do we need anything else for this role?
