Instructions to run a Parity dev node using Docker Compose

Pre-requisites

• Docker
• Docker-compose

Run a private network based on this repository

• Download/clone the files in this repository git clone https://github.com/oceanprotocol/docker-images.git
• cd into parity
• Run: docker-compose up -d
• This will run 3 validator/authority nodes and 3 user nodes

Add more authority nodes to the base network

• Run the private network as described above
• Create a new validator account: curl --data '{"jsonrpc":"2.0","method":"parity_newAccountFromPhrase","params":["nodeX", "nodeX"],"id":0}' -H "Content-Type: application/json" -X POST localhost:8545
  • Returns something like this: {"jsonrpc":"2.0","result":"0x00aa39d30f0d20ff03a22ccfc30b7efbfca597c2","id":0}
• Copy the file parity/keys/UTC--2018-05-22T13-53-28Z--ed4d9a7c-4206-bbf3-673c-fdd1d41b4dcb to parity/authorities and rename it to validatorX.json (pick a better name) then modify the contents to indent properly
• Add a simple text file named validatorX.pwd in parity/authorities and add the password nodeX (or whatever was specified in the "params":["nodeX", "nodeX"])
• Copy/paste one of the validator specs in the docker-compose.yml file and modify it to reflect the new node name and make sure to point to the new validatorX.json and validayorX.pwd files.
  • Also specify the address in the --engine-signer option
  • And add the name in the volumes section in the compose file
• Make a copy of parity/node0.network.key and modify the key inside this file (anything should do)
