run esplora with docker, but no 50001 port listened

[hanxianlong]

Hi there,
could anybody help me out..... I build the esplora following the instruction here :https://github.com/Blockstream/esplora#how-to-build-the-docker-image

and when I start the docker image with the following command, it started to sync blocks from mainnet and now it finished, but I cann't connect to it. When I checked the port in the docker container, I found there is no 50001 port listening, could anybody help me out? thanks...

docker run -p 50001:50001 -p 8080:80 \ --volume $PWD/data_bitcoin_mainnet:/data \ --rm -i -t esplora \ bash -c "/srv/explorer/run.sh bitcoin-mainnet explorer"

here is the listening port in the container:
