tl;dr; put your chain data in the node directory, alternatively change the --mount settings when you run it

git clone https://github.com/imylomylo/docker-komodod.git
cd docker-komodod
sudo docker build -t komdood .
sudo docker run -it -p 7770:7770 -p 127.0.0.1:7771:7771   --mount src=/home/me/docker-komodod/node,target=/root/.komodo,type=bind --mount src=/home/me/.zcash-params,target=/root/.zcash-params,type=bind komodod

it will drop you into a shell

/komodo/src/komodod -daemon &
/komodo/src/komodo-cli getinfo

Tips:

• It is designed so that you have the zcash-params already downloaded, so you can reuse them across many containers/blockchains in the ecosystem.
• The node directory has the blockchain data and config.
• Runs as root - this will get updated
• The node/komodo.conf file has rpcuser and rpcpassword. You can use curl to interact.
• Alternatively something like sudo docker exec /komodo/src/komodo-cli getinfo might work
• curl should work, something like curl --user rpcuser:passworddrowssap --data '{"method": "getinfo"}' http://127.0.0.1:7771
