As you will see in the following sections, we can run several containers at the same time and then interact with them individually. We can issue commands to extract information such as the Lightning node public key or to take actions such as opening a Lightning channel to another node. The +docker run+ and +docker exec+ commands together with +jq+ for JSON decoding are all we need to build a working Lightning Network that mixes many different node implementations. This enables us to try out diverse experiments on our own computer.
