The address of any particular tunnel is derived from the encryption key that protects it. As long as the same keys are used the addresses will be the same.

Can be configured by software automatically if they support BOB/SAM/I2CP.

I2PD

Config file is in ~/.i2pd or /var/lib/i2pd.

To export a local web server as an eepsite:

[http-in]
type = http
host = ourwebsite.com
port = 80
keys = our-website.dat

To create a local tunnel that will go to a particular server elsewhere:

[openvpn-client-simple]
type = udpclient
destination = something.b32.i2p
port = 1194
