Bitcoin / Development & Technical Discussion / Re: Bitcoin Docker!

Quote from: HeRetiK on July 23, 2019, 03:16:48 PM Which docker image are you using? And what precisely are you trying to do? If you are using that one -- https://hub.docker.com/r/nicolasdorier/docker-bitcoin -- and are trying to run some RPC commands then maybe you still have to take care of the following: Quote from: https://hub.docker.com/r/nicolasdorier/docker-bitcoin By default, Docker runs all containers on a private bridge network. This means that you are unable to access the RPC port (8332) necessary to run bitcoin-cli commands. There are several methods to run bitcoin-cli against a running bitcoind container. The easiest is to simply let your bitcoin-cli container share networking with your bitcoind container: Code: $ docker run -d --rm --name bitcoind -v bitcoin-data:/data NicolasDorier/bitcoin $ docker run --rm --network container:bitcoind NicolasDorier/bitcoin bitcoin-cli getinfo I use this image https://hub.docker.com/r/kylemanna/bitcoind. I tried to send json object like "{"jsonrpc": "2.0", "id":"curltest", "method": "getnetworkinfo", "params": [] }" via postman but i didn`n get response

Hi, guys!

How i can get more information about input? I need to know input value because i want to calculate fee.
Maybe you know how i can calculate fee easier because i want subtract sum of inputs with sum of outputs!Thx!
