Short answer: not by tags. In Prefect 3.x,

prefect deploy

can: - deploy all deployments in your

prefect.yaml

(

--deploy-all

), and - deploy a subset by name using patterns with

--name/-n

. It does not have a flag to filter which deployments to deploy by tags. The

--tags

option sets/overrides tags on the deployments being created; it does not filter selection. What you can do: - If your deployment names share a common token, use a name pattern:

prefect deploy --name "my-flow/ABC-*"

or

prefect deploy -n "ABC-*"

The

--name

flag supports patterns; examples in the help include things like

my-deployment-*

and

*-flow-name/deployment-*

. - If you must filter by tags, use a small one-liner (requires yq) to read

prefect.yaml

and deploy only those with tag ABC:

yq -r '.deployments[] | select(.tags[]? == "ABC") | .name' prefect.yaml | xargs -I{} prefect deploy -n {}

Or a quick Python script to parse

prefect.yaml

and call

prefect deploy -n ...

for matching names. References: - prefect.yaml guide - prefect deploy CLI reference If you can share how your deployments are named, I can suggest a

--name

pattern that matches your “ABC” set.

Yes — use a name pattern with

prefect deploy

. If the deployment names in your prefect.yaml start with `kl_`:

prefect deploy --name "kl_*"

If you want to match deployment names that start with

kl_

regardless of flow:

prefect deploy --name "*/kl_*"

If instead your flow names start with

kl_

and you want all their deployments:

prefect deploy --name "kl_*/*"

Notes: - Quote the pattern so your shell doesn’t expand it. - Run from your project root (where

prefect.yaml

lives). Docs: - prefect.yaml guide - prefect deploy CLI reference

Short answer: there isn’t a built-in pattern flag for running multiple deployments.

prefect deployment run

takes a single deployment name (or id) at a time. Workable CLI approaches: - Bash/zsh (runs each deployment whose name ends with /kl_*):

prefect deployment ls \
  | awk 'NR>2 && $1 ~ /\/kl_/ { print $1 }' \
  | xargs -n1 -I{} prefect deployment run {}

- PowerShell:

prefect deployment ls `
| Select-String -Pattern '/kl_' `
| ForEach-Object {
  $name = ($_ -split '\s+')[0]
  prefect deployment run $name
}

Notes: - The first column of

prefect deployment ls

is the deployment’s full name

<FLOW_NAME>/<DEPLOYMENT_NAME>

. We filter rows where the deployment part starts with

kl_

. - Add

--watch

,

--start-in

,

--start-at

, or

-p key=value

to each

prefect deployment run

if needed, e.g.:

... | xargs -n1 -I{} prefect deployment run {} --watch

Docs: - Deployment CLI reference - prefect.yaml guide If you prefer a more robust approach (avoiding parsing

ls

output), I can share a tiny Python snippet that queries deployments via the API and triggers runs for those with names matching

*/kl_*

.
