(automatically?) update media storage dump

[maxlath]

The last media storage dates from 2019, so an update is long overdue. inventaire.io entities media storage currently represents around 40GB of images stored in a replicated OpenStack Swift container. To have it automated, we would need to setup a VPS that can confidently have twice that space, plus some future-proof margin. The current way to go would be to use the python swift client to download the whole container on the VPS disk, tar the whole thing, and make it accessible on https://dumps.inventaire.io/inv/media/

Alternatively, it would be great to be able to just tell our service provider (OVH) OpenStack Swift instance to generate that archive and store it there, that would free us from the disk provisioning work load, but I couldn't find such an option.

I manually updated the media storage dump today.

# Load the OpenStack Swift credentials as environment variables, see https://stackoverflow.com/a/65247614
source ./openrc.sh
mkdir entities && cd entities
# Then using the swift command from the python3-swiftclient package
swift download entities
# Then create the archive file. The compression saves only 1.4GB, as all those jpg images are already compressed
cd ..
tar -cf entities.tar.gz entities
