…to match

Please check my instructions in the README; I couldn't get writefreely -config to work without first initializing the database, but of course it's how you configure the connection to the database; not sure what's up with that.

@BenOvermyer Could you take a look at this and let us know what you think?

[BenOvermyer]

The instructions are pretty long. I originally wrote docker-setup.sh to cut down on the amount of steps required to setup WF with docker-compose.

I would recommend updating that bash file to reflect the changes here, and using it to reduce the complexity of the setup process.

@koehn Any update on this? Could you move some of the steps into docker-setup.sh, as recommended?

[thebaer]

To anyone who wants to help out, please feel free to finish this up. As @BenOvermyer mentioned, we should move the steps in the documentation into docker-setup.sh

Closing this since there hasn't been any progress, and Docker documentation has moved to https://github.com/writefreely/documentation. Please feel free to improve things there!
