Postgresql password and dokku

Question

My server configuration is using dokku.

I wanted to update the server, and reboot it after a long time of operation.

After the server rebooted, the postgresql ip changed. I stupidly ran dokku postgresql:create to fix it (yes, i know it's stupid...), and now i keep getting the following error: FATAL: password authentication failed for user.

I matched the password strings i have in: /home/dokku/.postgresql/admin_pw and in: dokku config:set appname DATABASE_URL, but with no success.

Answer 1

You shouldn't have to create a new database for the app. If it's already been created, you should only see a response that database has been created.

This is achieved by

dokku postgres:link app db

Where app is the name of the app you wish to link and db is the name of the database you've previously created.

What will happen is the DATABASE_URL will be exposed in the app by an environment variable.
