I've tried to run this section while harbor runs on http. This fails as docker login command is issued and thinks harbor is on SSL.

The workaround is to do the following

1. Create 4 replication rules.

1. Then you can synchronize them at will

This step is not mandatory as even harbor mentions:

However, using HTTP is acceptable only in air-gapped test or development environments that do not have a connection to the external internet.

I've used curl -L https://storage.googleapis.com/harbor-releases/release-1.8.0/harbor-offline-installer-v1.8.0.tgz > harbor-offline-installer-v1.8.0.tgz

which is the minimal required version

the minimal required version doesn't need this step only one harbor.yml file is available

The file needs to change in one variable: hostname

the https port is not enabled

you may also change the harbor admin password
