I used the image "fullnode/bitcoin" to build a node of bitcoin. It runs successfully and I can see the debug.log. The node begin to Sync ledger(blocks).

I want to know how I can judge one node is fullnode or light node. The difference in bitcoin.conf? Or the difference in log?

Bitcoin Core only implements a fully-validating node mode. If this image runs Bitcoin Core, it's fully validating.

It is possible to run Bitcoin Core in pruning mode (prune setting in bitcoin.conf), where old block data is deleted after validation. Everything is still downloaded and validated as before, just not kept.
