Compute resources

Memory

Setting memory via acorn run has the highest order of precedence. When setting this, you operate under the --memory flag (-m for short).

note

Check out the memory reference documentation for more information.

--memory

When setting this value, you have two options - globally or per workload and you can do a combination of both. When setting the memory globally for the Acorn, you provide the memory you would like to set.

acorn run -m 512Mi foo

This will set all workloads in the foo acorn to have 512Mi of memory. Adjacently, you can set the memory of each individual workload in the Acorn using a workload=memory pattern.

acorn run -m nginx=512Mi foo

This will only update Acorn's nginx workload to have 512Mi of memory.

Finally, you can do a combination of both.

acorn run -m 256Mi,nginx=512Mi foo

This sets all workloads in the foo acorn to have 256Mi of memory except for the nginx workload which will have 512Mi of memory.

Compute Classes

To set a compute class at run time, you can utilize the --compute-class flag.

note

Check out the compute class reference documentation for more information about how compute classes work.

--compute-class

When setting compute classes, you have two options - globally or per workload, and you can do a combination of both. When setting the compute class globally for the Acorn, you provide the compute class you would like to set. Any classes defined for a specific container or job will overwrite the global value.

acorn run --compute-class sample foo

This will set all workloads in the foo acorn to use the sample compute class. Adjacently, you can set the memory of each individual workload in the Acorn using a workload=class pattern.

acorn run --compute-class nginx=sample foo

tip

This flag comes with auto completions! Hit tab to see compute classes that can be used.

This will only update Acorn's nginx workload to use the sample compute class.

Finally, you can do a combination of both.

acorn run --compute-class sample,nginx=different foo

This sets all workloads in the foo acorn to use the sample compute class except for the nginx workload which will have the different compute class.
