GCP CloudBuild -> Failed to trigger build: unrecognized arguments

[omar115]

I want to run a trigger by passing some substitution values. Here is my command:

gcloud beta builds triggers run my-service --branch=test-deploy-of-history --project=dev-project --substitutions=_SERVICE_NAME=flow

 But it is giving me this error:
ERROR: (gcloud.beta.builds.triggers.run) unrecognized arguments: --substitutions=_SERVICE_NAME=flow

can we not pass substitution values to trigger a build ? 
How to trigger the build if someone wants to pass extra arguments ?

Hi @omar115,

Welcome to the Google Cloud Community!

Take a look at Substituting Variable Values. It explains how to use default substitutions or define your own substitutions. 

You should try putting quotation marks on your value like so:

gcloud beta builds triggers run my-service --branch=test-deploy-of-history --project=dev-project --substitutions=_SERVICE_NAME="flow"

 There are also rules to follow when Using User-Defined Substitutions. Your variables should also be specified in these formats:

• $_SERVICE_NAME
• ${_SERVICE_NAME}

If the above options don't work, you can contact Google Cloud Support to further look into your case. Let me know if it helped, thanks!

I tried your command, I think the --substitutions is not supported though in the documentation they mentioned it:
https://cloud.google.com/sdk/gcloud/reference/beta/builds/triggers/run

After trying this command:

gcloud beta builds triggers run my-service --branch=test-deploy-of-history --project=dev-project --substitutions=_SERVICE_NAME="flow"

 I got this error:

ERROR: (gcloud.beta.builds.triggers.run) unrecognized arguments: --substitutions=_SERVICE_NAME=flow

I think whenever you are trying --substitutions it is saying that unrecognized arguments. I think it only supported in gcloud builds submit command not this command.

Can you check again ?

According to the Google Cloud CLI - Release Notes version 438.0.0

-Added flag to specify substitutions in gcloud builds trigger runs 

 See reference here. You can do the gcloud components update which updates all your installed components to the latest versions.
