Upgrade from v3.4.10 to v3.5.x

[davama]

Hello,

Im struggling to upgrade my netbox docker instance to the latest tag image.

I install additional plugins so i've done as stated here to my Dockerfile since now the secret_key needs to be >=50 characters.

I pretty much get similar error as here but havent been able to resolve it.

Looking at the upgrade docs i notice that there is a reference to an upgrade.sh script. I noticed that after v3.4.10 that script does not exist. Not sure if this has anything to do with me not being able to upgrade...

for i in v3.4.8 v3.4.9 v3.4.10 v3.5.0 v3.5.1; do echo $i; docker run --rm netboxcommunity/netbox:$i ls /opt/netbox/upgrade.sh; done
v3.4.8

v3.5.0
ls: cannot access '/opt/netbox/upgrade.sh': No such file or directory
v3.5.1
ls: cannot access '/opt/netbox/upgrade.sh': No such file or directory

I even tried copying the upgrade.sh file from v3.4.10 and add it as a volume and run it but also failed

root@netbox-container:/opt/netbox# ./upgrade.sh

Honestly at a lost.
Any input to what I am doing wrong is appreciated

Thank you,

The issue in your first outputs is that your secret key configuration does not meet the minimum required 50 characters for 3.5+. I see you are saying you are aware of this, can you clarify what you did to generate/update your secret key for 50+characters? Otherwise:

From your first output
netbox | django.core.exceptions.ImproperlyConfigured: SECRET_KEY must be at least 50 characters in length. To generate a suitable key, run the following command: python /opt/netbox/netbox/generate_secret_key.py

It sounds like you are running this from inside docker, so check your environment configuration and expand your SECRET_KEY environment variable to be 50+ characters

aaaahhh

i thought it was 50 because

echo 'secret_keystringbla' | wc -m
50

but it is actually 49.... i missed including the -n .... 😢

echo -n 'secret_keystringbla' | wc -m
49

the upgrade is good now... *sigh*

Thank you @FliesLikeABrick for the quick response!

i still am see the same error even after confirming that the secret key is longer than 50 chars
