Running a full node for Mosaic

Chains Utils for OpenST Mosaic

Configuration files for building utility chain docker images and running utility chains. Each directory includes a Dockerfile and other required files to build the docker image for a specific node.

Note the different ports that the different nodes require.

Example files and helper scripts

The root directory contains an example docker-compose.yml that you can use to run a mosaic set-up. Adapt it to your needs.

You can run the example file to run a rinkeby and a utility chain 1409 node plus a rust mosaic node that connects to the two geth nodes:

docker-compose --project-name mosaic up

The root directory contains a geth-compose.sh script to manage creating geth node containers and side-loading chain data. Run ./geth-compose.sh help for help on how to use it.

Utility nodes

Utility chain 1409

To run a node that connects to the 1409 utility chain, you can run:

docker run -it -v utility1409:/usr/utility_node -p 8547:8547 -p 8548:8548 -p 30304:30304 openstfoundation/utility-node:latest-uc1409

Note that 8547 is the default RPC port and 8548 is the default ws port for the utility chain 1409 image. You can override the command to specify different ports. See the Dockerfile for the default command, including the boot nodes:

docker run -it -v utility1409:/usr/utility_node -p 8547:8547 -p 8548:8548 -p 30304:30304 openstfoundation/utility-node:latest-uc1409 --networkid 1409 --datadir ./uc_node --port 30304 --rpc --rpcapi eth,net,web3,personal --rpcport 8547 --ws --wsport 8548 --bootnodes enode://a4a27ee96b770d2ae801c04ac32ac494e222e0b40442b0e8400a762e5097658c47d4f66530a1459c17847215315e7dab1d99481e99cfbe9988a1bf02c2083b2e@35.173.117.179:30301,enode://08a5d0bcff92d06a8c1f7acef47d37610ffc0fb5146b693111b73656e0e2001c522971124eb8321687dcf21edd87dcf04d20276c9153ce5d045f075337c362c7@35.172.92.122:30301

⚠️ If you want to access the ethereum node, you need to enable access from the host as per the go-ethereum documentation. You can do that for example by adding --rpcaddr 0.0.0.0, if you want to access RPC from other containers and/or hosts:

docker run -it -v utility1409:/usr/utility_node -p 8547:8547 -p 8548:8548 -p 30304:30304 openstfoundation/utility-node:latest-uc1409 --networkid 1409 --datadir ./uc_node --port 30304 --rpc --rpcaddr 0.0.0.0 --rpcapi eth,net,web3,personal --rpcport 8547 --ws --wsport 8548 --bootnodes enode://a4a27ee96b770d2ae801c04ac32ac494e222e0b40442b0e8400a762e5097658c47d4f66530a1459c17847215315e7dab1d99481e99cfbe9988a1bf02c2083b2e@35.173.117.179:30301,enode://08a5d0bcff92d06a8c1f7acef47d37610ffc0fb5146b693111b73656e0e2001c522971124eb8321687dcf21edd87dcf04d20276c9153ce5d045f075337c362c7@35.172.92.122:30301
