user2345: I am working on running the Cardano Node with Docker. I Got it working (running cardano-cli version 1.27.0) but when i execute the following command cardano-cli query tip --mainnet I expect a block result in the era "shelley" bit it shows me I am in the "Byron" era. The epoch parameters returns 'null' instead of a value

user1142: The behavior you describe is expected. After starting the Docker container, the cardano node will start downloading the whole blockchain. Depending on your system and internet connection it can take several hours to download the whole blockchain.
While the node downloads the blockchain, you can use the cardano-cli query tip --mainnet command to check on the progress. You can compare the current slot of your node with the latest slot (see https://explorer.cardano.org/) to see how much of the blockchain you already downloaded.
As soon as your node has downloaded the whole blockchain you can start to create transactions etc.
