A docker swarm contains the following node: Whic of the nodes should be configured as DOCKER_HOST in order to run services on the swarm? (Specify ONLY the HOSTNAME of one of the potential target nodes)

A. In a Docker Swarm, you need to set the DOCKER_HOST environment variable on the manager node in order to run services on that node. In your example, node "node-1" is the manager node (with a * symbol) and its status is "Ready" and "active", and it is also the "Leader". Therefore, you should set the DOCKER_HOST environment variable on node "node-1". To set the DOCKER_HOST environment variable, you can use the following command (assuming that you are using a bash shell): export DOCKER_HOST=tcp://node-1:2375 This will set the DOCKER_HOST environment variable, causing Docker commands to default to connecting to port 2375 on node "node-1". Please note that you can also add the above command to ~/.bashrc or ~/.bash_profile file to automatically set the DOCKER_HOST environment variable whenever a new bash shell is opened. It should be noted that if your Docker Swarm uses a different network mode (e.g., overlay network), then you may need to specify a different network mode and port in the DOCKER_HOST environment variable. The specific situation depends on your Docker Swarm configuration.
