In the Google Cloud CLI, configurations enable you to set properties that
affect the behavior of the active gcloud 
session. A default 
configuration is
created when you initialize Google Cloud CLI and you can create other named
configurations.
A configuration can include default values for specific properties so that you do not need to specify them in your commands.
For more information about using configurations, see the gcloud config documentation.
Setting defaults
You can set a default project, repository, and repository location in the Google Cloud CLI active configuration so that you don't need to include them in commands where those values are required.
If you do specify a value for a project, repository, or repository location,
that value overrides the configured default. You can do this with the --repository 
or --location 
flag in your command.
If you're using repository modes other than standard mode, or frequently using repositories in different locations, setting default values might not be helpful.
Setting a default project
To set default project for all gcloud 
commands, run the command:
 gcloud  
config  
 set 
  
project  
 PROJECT 
 
 
Replace PROJECT with the ID of the project or fully qualified identifier for the project.
To override the default, use the --project 
flag in your command. For example
   
gcloud  
artifacts  
packages  
list  
--project = 
my-project 
 
Setting a default repository
To set a default repository, run the command:
 gcloud  
config  
 set 
  
artifacts/repository  
 REPOSITORY 
 
 
Replace REPOSITORY with the name of the repository, or fully qualified identifier for the repository.
To override the default, use the --repository 
flag in your command. For example
 gcloud  
artifacts  
packages  
list  
--repository = 
my-repo 
 
Setting a default location
To set a default repository location, run the command:
 gcloud  
config  
 set 
  
artifacts/location  
 LOCATION 
 
 
Replace  LOCATION 
 
with the regional or multi-regional location 
of the repository.
To view a list of supported locations, run the command:
 gcloud  
artifacts  
locations  
list 
 
To override the default, use the --location 
flag in your command. For example
 gcloud  
artifacts  
packages  
list  
--repository = 
my-repo  
--location = 
us-central1 
 
Removing default values
When you remove a default value for a configuration property, you must specify
it in gcloud 
commands that require the property.
To unset the default project run the following command:
 gcloud  
config  
 unset 
  
project 
 
To unset the default repository, run the following command:
 gcloud  
config  
 unset 
  
artifacts/repository 
 
To unset the default location, run the following command:
 gcloud  
config  
 unset 
  
artifacts/location
