Unable to deploy contract on Besu network(docker) using dynamic IP

Question

I am stuck with a weird situation. I create a local Ethereum network with Hyperledger Besu in docker environment. I try to deploy contracts to a rpc node using Truffle(different container in same docker network).

1.) When I have static IP configured for Besu nodes in the docker-compose, and I use the service name in truffle, contract deployment goes through fine.

2.) If I do not configure static IPs, in the docker-compose, for some reason the contract deployment is stuck. Why?

I have tried to see if there is network connectivity issue. Pinged the Besu node via hostname and IP(dynamically allocated by docker) which went through. Here's the trailing logs I see, post which it is indefinitely stuck -

Here's a snippet of the docker-compose -

Here's a snippet of the truffle-config.js file -

     besu_docker: {     
            host: "rpc.node2.eth.local", 
            network_id: "*",
            port: 8555,
            gas: 4500000,
            gasPrice: 0
       },

Is there something obvious I am missing?

Answer 1

I think you have an error in your truffle-config.js The port should be 8545 instead of 8555.
