## The problem
Issue astronomer/astro-cli#1267 (closed, 8 comments): While attempting to update the worker-queue's concurrency through ```astro deployment worker-queue update``` command, using the flag ```--concurrency int``` to alter the concurrency of a given astro machine doesn't change the concurrency value for the updated worker queue. However, the astromachine gets updated successfully. ``` shrividyahegde@Shrividyas-MacBook-Pro Documents % astro deployment worker-queue update --concurrency 30 Select a Deployment # DEPLOYMENT NAME RELEASE NAME DEPLOYMENT ID DAG DEPLOY ENABLED 1 gcp_test_standard planetoidal-gegenschein-1614 clix117rh103281jxa9sgyorxg...

## What fixed it
This was fixed in a later astro-cli release. Update the CLI and the astro deployment worker-queue update --concurrency N command works again. Concurrency is validated against the worker type, so keep the value inside the allowed range for your machine: A5 takes 1-15, A10 1-30, A20 1-60, A25 1-120. Zero or out-of-range values are rejected with an error that tells you the valid range.
