Can someone post an example bitcoin.conf file for testnet? How do you connect to testnet through docker?
I dug this up from past runs on that mode. Note that it will likely take a long time (hours or roughly a day) depending on your connection speed to sync the testnet blockchain. There are ways to check progress, but I don’t remember. I’d recommend looking for bitcoin testnet specific documentation for more details.
