How to create a service account for a bigquery dataset from the cli

I've found instructions how to generate credentials for the project level but there aren't clear instructions on adding a service account to only a specific dataset using the cli.

I tried creating the service account:

gcloud iam service-accounts create NAME

and then getting the dataset:

bq show \
--format=prettyjson \
project_id:dataset > path_to_file

and then adding a role to the access section

    {
      "role": "OWNER",
      "userByEmail": "[email protected]"
    },

and then updating it. It seemed to work because I was able to create a table but then I got an access denied error User does not have bigquery.jobs.create permission in project when I tried loading data into the table.

When I inspected the project in the cloud console, it seemed as if my service account was added to the project rather then the dataset, which is not what I want but also does not explain why I don't have the correct permissions. In addition to owner permissions I tried assigning editor permission and admin, neither of which solved the issue.

It is not possible for a service account to only have permissions on a dataset level and then run a query. When a query is invoked, it will create a job. To create a job, the service account to be used should have permission bigquery.jobs.create added at a project level. See document for required permissions to run a job.

With this in mind, it is required to add bigquery.jobs.create at project level so you can run queries on the shared dataset.

NOTE: You can use any of the following pre-defined roles as they all have bigquery.jobs.create.

  • roles/bigquery.user
  • roles/bigquery.jobUser
  • roles/bigquery.admin

With my example I used roles/bigquery.user. See steps below:

  1. Create a new service account ([email protected])
  2. Get the permissions on my dataset using bq show --format=prettyjson my-project:mydataset > info.json
  3. Add OWNER permission to service account in info.json
{
  "role": "OWNER",
  "userByEmail": "[email protected]"
},
  1. Updated the permissions using bq update --source info.json my-project:mydataset
  2. Check BigQuery > mydataset > "SHARE DATASET" to see if the service account was added.

enter image description here

  1. Add role roles/bigquery.user to service account using gcloud projects add-iam-policy-binding myproject --member=serviceAccount:[email protected] --role=roles/bigquery.jobUser
