Docker Node Label Add

The docker node label add command is used to add a label to a Docker Swarm node. Labels are used to tag nodes with metadata that can be used for filtering tasks or managing services.

Syntax

docker node label add <NODE> <LABEL>

Parameters

• NODE: The ID or name of the node to add the label to.
• LABEL: The label to add in the format key=value.

Examples

Add a label to a node

docker node label add worker-1 environment=production

This command will add the label environment=production to the node named worker-1.

Notes

• You can add multiple labels in one command by separating them with a space.
• Labels can also be added during node creation by using the --label option of the docker swarm join command.
• Labels can be removed with the docker node label rm command.
