To get up and running with Cardano, you can spin up a node like this …

    -v shelley-data:/opt/cardano/data \
    nessusio/cardano run

Slot Leader Schedule

We can now obtain the leader schedule for our pool.

Details on how to do this are here

docker run -it --rm \
  -v ~/cardano:/var/cardano/local \
  -v shelly-data00:/opt/cardano/data \
  nessusio/cardano leader-logs \
    --vrf-skey /var/cardano/local/keys/pool/vrf.skey \
    --sigma 0.000233 \
    --d-param 0.32 \
    --epoch 240

Checking leadership log for Epoch 240 [ d Param: 0.32 ]
2021-01-06 06:36:13 ==> Leader for 60682, Cumulative epoch blocks: 1
2021-01-06 09:16:55 ==> Leader for 70324, Cumulative epoch blocks: 2
2021-01-08 00:15:49 ==> Leader for 210658, Cumulative epoch blocks: 3
2021-01-09 23:28:40 ==> Leader for 380629, Cumulative epoch blocks: 4

This functionality is available through our multi-arch docker image that runs on Intel and ARM64 - i.e. also on the RaspberryPi 4

Other useful built-in functionality includes …
