How to change the project in GCP using CLI commands

gcloud config set project $MY_PROJECT_ID

#=>

Updated property [core/project].

You may also set the environment variable $CLOUDSDK_CORE_PROJECT.

Make sure you are authenticated with the correct account:

gcloud auth list
* account 1
  account 2

Change to the project's account if not:

gcloud config set account `ACCOUNT`

Depending on the account, the project list will be different:

gcloud projects list

- project 1
- project 2...

Switch to intended project:

gcloud config set project `PROJECT ID`

You should actually use the project ID and not the name as the other answers imply.

Example:

gcloud projects list

PROJECT_ID              NAME                  PROJECT_NUMBER
something-staging-2587  something-staging     804012817122
something-production-24 something-production  392181605736

Then:

gcloud config set project something-staging-2587

It's also the same thing when using just the --project flag with one of the commands:

gcloud --project something-staging-2587 compute ssh my_vm

If you use the name it will silently accept it but then you'll always get connection or permission issues when trying to deploy something to the project.
