teams-backend is an API server for NAIS team management, along with propagation to external systems.
ADR: https://github.com/nais/core/blob/main/adr/010-console-nais-io.md
teams-backend needs a go version as per the go.mod file, and depends on a running PostgreSQL database. For convenience, a Docker Compose configuration is provided.
docker compose up -d
make teams-backend
./bin/teams-backendRunning the compiled binary without any arguments will start an instance that does not touch any external systems. The API server runs GraphiQL at http://localhost:3000.
In order to make any request to the API server, your requests must be authenticated with a Authorization: Bearer <api-key> header. For local development the TEAMS_BACKEND_STATIC_SERVICE_ACCOUNTS environment variable can be used to create a service account with the necessary permissions. Refer to the configuration documentation below for more information.
For a combination of more tools running locally (hookd, Teams frontend and more), check out the nais/features-dev repo.
teams-backend can be configured using environment variables. For a complete list of possible configuration values along with documentation refer to the pkg/config package. Some configuration values that require more in depth documentation can be found below.
JSON-encoded object with information about the GCP clusters to use with teams-backend.
Example:
{
"dev": {
"teams_folder_id": "123456789012",
"project_id": "project-id-123"
},
"prod": {
"teams_folder_id": "123456789013",
"project_id": "project-id-456"
}
}The keys in the object refer to the environment names to use. In the example above we have two environments, dev and prod. Each environment maps to a JSON-object with two keys:
teams_folder_id: The numeric ID of theteamsfolder in the given environment, where all team projects will be created.project_id: The ID of the GCP project for the environment/cluster.
teams-backend can create a list of service accounts with predefined API keys and roles on start up.
Example:
[
{
"name": "nais-service-account-1",
"apiKey": "key1",
"roles": [
{"name": "Team viewer"},
{"name": "User viewer"}
]
},
{
"name": "nais-service-account-2",
"apiKey": "key2",
"roles": [
{"name": "Team creator"}
]
}
]The service account names must begin with nais-. Each role in the roles list must be valid role names. Role names can be fetched from the GraphQL API:
query {
roles
}teams-backend will, on each start up of the application, ensure that the service accounts specified in the JSON value exists. If a service account is removed from the JSON value, teams-backend will remove it from the database as well.
A config file for minimal working local setup with usersync / login (dev-nais.io user required) enabled can be downloaded like this:
gcloud --project="nais-management-7178" secrets versions access --secret="teams-backend-local-config" latest # (nais.io users have access to this secret)teams-backend runs GraphiQL by default, and this can be used to explore and use the GraphQL API. After you have started teams-backend you will find graphiql on http://localhost:3000. Use the TEAMS_BACKEND_STATIC_SERVICE_ACCOUNTS configuration parameter to create a service accounut to use with the API.
Some common queries is listed below.

}teams-backend uses reconcilers to sync team information to external systems, for instance GitHub or Azure AD. The supported reconcilers can be configured with a combination of environment variables and configuration options set through the GraphQL API. By default all reconcilers are disabled when teams-backend starts up. To enable a reconciler, the enableReconciler mutation in the GraphQL API can be used. Keep in mind that the reconciler enabled status is persisted in the database, so if you enable one or more reconcilers they will still be enabled the next time you start up the teams-backend application, unless you start up with an empty database.
The implemented reconcilers and their purpose are documented below.
To create groups in a Google Workspace organization and sync members the google:workspace-admin reconciler can be enabled. Once a team is created in teams-backend the reconciler will create a group for the team in the connected Google Workspace. Given a teams-backend team with a slug set to my-team the Google workspace group will end up with:
- Email:
nais-team-my-team@<domain> - Name:
nais-team-my-team
When a user is added / removed to the team in teams-backend the reconciler will make the same change in the Google Workspace group.
Each team in teams-backend can get a GCP project by using the google:gcp:project reconciler. The reconciler will create a project in each cluster that teams-backend is configured to use. When creating a project the team group will be set as the owner of the project.
To generate NAIS namespaces for a team in the configured cluster the nais:namespace reconciler can be used.
The azure:group reconciler works in a similar fashion as the Google Workspace one, but instead it will create a security group in Azure AD. The Azure AD tenant must share the same domain as the Google Workspace, and the email address of the users must match up for teams-backend to correctly identify the users.
The github:team reconciler can create a GitHub team for each teams-backend team, and maintain team memberships based on the information found in teams-backend. To use this reconciler a GitHub App must exist. The app requires the following scopes:
- Organization Administration:
read - Organization Members:
readwrite
Install the application on the organization and obtain the private key, application ID, and installation ID.
To generate NAIS deploy keys for each teams-backend team the nais:deploy reconciler can be used.
Refer to the NAIS docs for botstrapping other systems to work with teams-backend.
The image is signed "keylessly" (is that a word?) using Sigstore cosign. To verify its authenticity run
cosign verify \
--certificate-identity "https://github.com/nais/teams-backend/.github/workflows/build_and_push_image.yaml@refs/heads/main" \

The images are also attested with SBOMs in the CycloneDX format. You can verify these by running
cosign verify-attestation --type cyclonedx \
