This is the repository for the tloriato/*-multichain docker images.
- tloriato/base-multichain: A base Ubuntu with the latest Multichain deamon installed
- tloriato/master-multichain: Based on the "base" image running a master node, creates a blockchain and runs it. Important: only for development since any node can connect, anyone can administer and the RPC interface is open to all.
- tloriato/node-multichain: Based on the same "base" image and connects to the master node
- tloriato/explorer-multichain: A node with the Multichain explorer installed
Use this docker-compose.yml and run:
sudo docker-compose up
For the time being you have to publish it yourself manually using a terminal, but here's the flow:
- Create a Stream for Records:
docker exec docker-multichain_masternode_1 multichain-cli MyChain create stream Registros '{"restrict":"offchain"}' '{"key1":"value1"}' - Copy the content on the single-line file registroEmpresaAcme.json and replace the X for it:
docker exec docker-multichain_masternode_1 multichain-cli MyChain publish Registros 'CNPJdaEmpresa?' 'X' - Create a Stream for Invoices:
docker exec docker-multichain_masternode_1 multichain-cli MyChain create stream Nickelodeon '{"restrict":"onchain"}' '{"key1":"value1"}' - Copy the content on the single-line file metaDadoNFAcme.json and replace the X for it, and file notaFiscalAcme.json for Y:
docker exec docker-multichain_masternode_1 multichain-cli MyChain publish Nickelodeon 'X' 'Y' offchain)
