Migrating from DO install to Docker

[SebBorbely]

Hi,

Invetree installation on Digital Ocean:

# Version Information:
InvenTree-Version: 0.17.11
Django Version: 4.2.17



Database: postgresql
Debug-Mode: False
Deployed using Docker: False
Platform: Linux-5.4.0-212-generic-x86_64-with-glibc2.31
Installer: None

Active plugins: [{'name': 'InvenTreeBarcode', 'slug': 'inventreebarcode', 'version': '2.1.0'}, {'name': 'InvenTreeCoreNotificationsPlugin', 'slug': 'inventreecorenotificationsplugin', 'version': '1.0.0'}, {'name': 'InvenTreeCurrencyExchange', 'slug': 'inventreecurrencyexchange', 'version': '1.0.0'}, {'name': 'InvenTreeLabel', 'slug': 'inventreelabel', 'version': '1.1.0'}, {'name': 'InvenTreeLabelMachine', 'slug': 'inventreelabelmachine', 'version': '1.0.0'}, {'name': 'InvenTreeLabelSheet', 'slug': 'inventreelabelsheet', 'version': '1.0.0'}, {'name': 'DigiKeyPlugin', 'slug': 'digikeyplugin', 'version': '1.0.0'}, {'name': 'LCSCPlugin', 'slug': 'lcscplugin', 'version': '1.0.0'}, {'name': 'MouserPlugin', 'slug': 'mouserplugin', 'version': '1.0.0'}, {'name': 'TMEPlugin', 'slug': 'tmeplugin', 'version': '1.0.0'}]

I'm trying to move my installation of Inventree which is currently running on DigitalOcean to a docker installation.
I've been following the migration steps described in: https://docs.inventree.org/en/stable/start/migrate/
However I have encountered a road block when trying to do the data export:
invoke export-records -f data.json

This gave me the following error:

Exporting database records to file '/opt/inventree/data.json'

I tried manually specifying the static location, after which it complained about missing media location. Did the same again then it wanted backup location, so did the same again and now its giving me this error message:

I am a bit lost now how to proceed, or whether I am even going down the right direction.
My main goal with this is to have a local save of my Inventree data as their is no way to export a digital ocean droplet. (the docker install is just to test that it has exported correctly). If you have any comments on a better way of doing this I am very much open to suggestions.

Any help would be very much appreciated on this front.

the DO image is using the package installer so you will need to use inventree run cli instead of invoke

Thanks, that's all working now. Got the docker server running with all the data and media files.
