  4. DB move from Cloud to local instance in Docker on Win11 PC

DB move from Cloud to local instance in Docker on Win11 PC

Added by James Spedding 2 months ago

I wonder if you could help me? I have trialled OP online and want to move the project on to a local instance of OP running in a Docker Container on a Win11 PC.

I understand that this is not officially supported but I wonder if anyone could offer advice?

Firstly I installed Docker Desktop (along with associated VM BIOS changes etc.) then downloaded OpenProject as an image through Docker. It now runs nicely with the demo project. I was trying to follow the official documentation to migrate the data but as I'm not running on a Linux machine the process fails. I've requested the backup token and downloaded the openproject.sql file to my local machine. I couldn't find anything specific online so asked Perplexity and it generated a couple of guides for supposedly achieving the database migration and schema renaming but none has been successful. I wonder if you have any advice about how to go about this properly or existing guides online?

Many thanks, James

RE: DB move from Cloud to local instance in Docker on Win11 PC - Added by James Spedding 2 months ago

This is the Answer I've been working through. I'm not sure it's corect but I have managed to get to stage 4. Error details below

Answer

To import an openproject.sql database backup from cloud-based storage into a local OpenProject instance running in a Docker container on a Windows PC, follow these steps:

1. Retrieve the Backup

  • Download the openproject.sql file from your cloud storage to a local directory, e.g., C:\OpenProjectBackup.

2. Locate the PostgreSQL Container

  • Identify the PostgreSQL container used by OpenProject:


  • bash: docker ps 

    Look for the container running PostgreSQL (it may be part of the OpenProject setup).

3. Copy the Backup File into the Container

  • Use the docker cp command to copy the SQL file into the PostgreSQL container:


  • bash: docker cp C:\OpenProjectBackup\openproject.sql <postgres-container-id>:/tmp/

4. Restore the Database

  • Access the PostgreSQL container:


  • bash: docker exec -it <postgres-container-id> bash 

  • Switch to the PostgreSQL user and restore the database:


    • bash: psql -U postgres -d openproject -f /tmp/openproject.sql

      Replace openproject with your database name if it differs.

5. Restart OpenProject

  • Restart the OpenProject container to apply changes:


  • bash: docker restart <openproject-container-id> 

This process restores your database backup and ensures it is operational in your Docker-based OpenProject instance.


I can get to 4 but when I run root@8d8192ac553a:/app# psql -U postgres -d openproject -f /tmp/openproject.sql

I get the error_: psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL:  Peer authentication failed for user "postgres"_

Any further guidance gratefully received.

I found something that said that the postgres username and password were both openproject so I tried that as a username but with no success, even forcing the password prompt. 

I then tried with username root but the error said there is no role called root. 

I think I'll have to give up and remake the whole project from scratch.

RE: DB move from Cloud to local instance in Docker on Win11 PC - Added by James Spedding 2 months ago

I managed to get the command to run by switching to the postgres superuser first

root@8d8192ac553a:/app# su - postgres

I was then able to run postgres@8d8192ac553a:~$ psql -U postgres -d openproject -f /tmp/openproject.sql

Unfortunately I'm now struggling with the Schema rename ] https://www.openproject.org/docs/installation-and-operations/operation/restoring/#changing-the-database-schema-from-cloud-to-on-premises
