[bookstack] README does not mention that apparently a database is required?

[kastl-ars]

Chart Name

bookstack

Chart Version

0.17.2

Bug Description

I used the installation instructions from the README, without any values.yaml file.

helm install bookstack gabe565/bookstack

The bookstack pod threw a warning in the logs that no database could be reached.

Setting mariadb.enabled to true added a database instance, and after deleting the pods the new pod came up fine and started the database migrations.

I would propose to add a --set mariadb.enabled=true to the example instructions.

values.yaml

No response

@kastl-ars Sorry for the trouble! I've gotten a few issues about this now, so I'll go ahead and enable it by default. Also note that persistence is disabled by default! Make sure you set the following values:

persistence:
  config:
    enabled: true

mariadb:
  primary:
    persistence:
      enabled: true

Do you think those should also be enabled by default? Without them, data will not be persisted between container restarts.

Thanks for taking care, @gabe565.

I think having "sane" defaults, aka a fully working setup, is a good idea. So I would vote for enabling both mariadb and persistence.

And I would add a stanza to the README to describe the defaults, i.e. that persistence is enabled and can be tweaked by setting e.g. the storageClass. And that a database is required, the default is to use mariadb, but you can bring your own if you wish.
