user7532: Is there a Devnet(single node) available for Cardano?. With other blockchains you can get instruction abt configuring Devnet, Testnet and Mainnet. With Cardano I read only about Testnet and Mainnet. Can you please let me know if devnet configuration is available?.

user387: Running a local single-node cardano devnet is actually quite simple. But I also do not remember seeing any documentation about it.
Maybe this docker-compose.yaml from the Hydra demo and the configuration used in there will help you get started: https://github.com/input-output-hk/hydra-poc/blob/cc8f40fcd21261329ca36a3f7c03981721977631/demo/docker-compose.yaml#L4-L22
The hydra demo starts a single cardano-node given some fixed credentials, which starts in the wanted Era right away and produces blocks as the single stake pool on the network. Make sure to also check out the prepare-devnet.sh script, which needs to be executed before starting the docker container (it sets start times of the devnet, which need to be recent enough)
