I tried hard to install the chart manually but I failed miserably.
Because you need a really long values-local.yaml in order to succeed.
And yet I could watch the NC pod failing the installation, but still it's up and running and I see:
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
Also, just to be sure, did you remove your charts/ dir and run helm dep upgrade before you ran the manual installation? Because your screenshot looks like your Nextcloud couldn't reach the database
Checked out 1015-update-to-nc-23 (assuming that's the branch you were testing)
Copied values-local.yaml.example to values-local.yaml
Edited all passwords to be passwords (only alphanumeric characters to be sure no weird yaml formatting issues were introduced)
Replaced all files.your.domain with files2.my.domain (files2 so it wouldn't conflict with the already installed files. from Stackspin. I tested on a Stackspin cluster)
Replaced all office.your.domain with office2.my.domain (office2 for the same reason)
commented out the sociallogin part because I don't need it at present.
I'm giving up - I now recieve a 503 after installation.
My argument is: "Work's on your machine, but not on mine" should be enough to implement a non-biased, reproducible setup in CI, that's why I'd like to do #965 (closed) soon.
