If you are trying to deploy an app by pushing to the dokku remote like this, and get a message that Everything up-to-date, you may find this frustrating, and be tempted to make a “fake change” to force a redeploy.
[pconrad@csilvm-01 STARTER-team02]$ git push dokku main
Everything up-to-date
But there’s an better way that doesn’t involved making fake changes to the code: an empty commit. Here’s how:
[pconrad@csilvm-01 STARTER-team02]$ git commit --allow-empty -m "pc - empty commit to push to dokku"
[main 8253cbd] pc - empty commit to push to dokku
[pconrad@csilvm-01 STARTER-team02]$ git push dokku main
... Dokku starts deploying
An even better way, if it works
If you have a terminal open to the shell prompt on dokku-xx.cs.ucsb.edu, you can also try these commands:
dokku ps:restart app-namedokku ps:rebuild app-name
