How to label devices

MAAS offers a wide range of device labelling: tags that can carry information; static annotations which can identify and describe machines; and dynamic annotations which can describe current workloads for deployed machines.

Tag machines

The most common tags are machine tags, which can not only help you sort machines, but also help to configure that machine, e.g., with kernel options, when being deployed.

Annotate machines

You can also annotate machines. Static annotations stick with a machine as long as it exists. Dynamic annotations, on the other hand, last only as long as a specific deployment.

Use machine tags

There are quite a few nuances to machine tags.

Use controller tags

You can also tag controllers to help easily tell them apart.

Use storage tags

Storage tags help you mark and remember specialized storage configurations.

Use network tags

Network tags let you remember how you set up specific network interfaces.
