Create Team LBAC rules for the Loki data source
Team LBAC is available on Cloud for data sources created with basic authentication. Any managed Loki data source can NOT be configured with Team LBAC rules.
Before you begin
- Be sure that you have admin data source permissions for Grafana.
- Be sure that you have a team setup in Grafana.
Create a Team LBAC Rule for a team
- Navigate to your Loki datasource
- Navigate to the permissions tab
- Here, you’ll find the Team LBAC rules section.
- Add a Team LBAC Rule
- Add a new rule for the team in the Team LBAC rules section.
- Define Label Selector for the Rule
- Add a label selector to the rule. Refer to Loki query documentation for guidance on the types of log selections you can specify.
Best practices
We recommend you only add query
permissions for teams that should use the data source and only Admin
have Admin
permissions.
We recommend for a first setup, setting up as few rules as possible for each team and make them additive for simplicity.
For validating the rules, we recommend testing the rules in the Loki Explore view. This will allow you to see the logs that would be returned for the rule.
Tasks
Task 1: One rule setup for each team
One common use case for creating an LBAC policy is to have specific access to logs that have a specific label. For example, you can create a label policy that includes all log lines with the label.
We have two teams, Team A and Team B with Query
permissions. Loki access is setup with Admin
roles to have Admin
permission only.
Team A has a rule
namespace="dev"
.Team B has a rule
namespace="prod"
.
A user that is part of Team A will have access to logs that match namespace="dev"
.
A user that is part of Team B will have access to logs that match namespace="prod"
.
A user that is part of Team A and Team B will have access to logs that match namespace="dev"
OR namespace="prod"
.
Task 2: One rule setup for a team Exclude a label
One common use case for creating an LBAC policy is to exclude logs that have a specific label. For example, you can create a label policy that excludes all log lines with the label secret=true by adding a selector with secret!="true"
when you create an access policy:
We have one team, Team A Query
permissions. Loki access is setup with Admin
roles to have Admin
permission only.
- Team A has a rule
secret!="true"
.
A user that is part of Team A will NOT have access to logs that match secret!="true"
.
Task 3: Multiple rules setup for one team
We have two teams, Team A and Team B with Query
permissions. Loki access is setup with Admin
roles having Admin
permission.
Team A has rule
cluster="us-west-0", namespace=~"dev|prod"
configured.Team B has rule
cluster="us-west-0", namespace="staging"
configured.
A user that is only part of Team A will have access to logs that match cluster="us-west-0" AND (namespace="dev" OR namespace="prod")
.
A user that is only part of Team B will have access to logs that match cluster="us-west-0" AND namespace="staging"
.
A user in Team A has access to logs in cluster us-west-0 with namespaces dev
and prod
. A user in Team B has access to to everything in cluster us-west-0, except namespace prod. So basically, user who is member of both team A and team B has access to everything in cluster us-west-0.
A user that is not part of any Team with Editor/Viewer
role will not have access to query any logs.
Important
A Admin
user that is part of a Team with will only have access to that teams logs
A Admin
user that is not part of any Team with Admin
role will have access to all logs
Task 4: Rules that overlap
We have two teams, Team A and Team B.
Team A has a rule
namespace="dev"
.Team B has a rule
namespace!="dev"
.
A user in Team A will have access to logs that match namespace="dev"
.
A user in Team B will have access to logs that match namespace!="dev"
.
NOTE: A user that is part of Team A and Team B will have access to all logs that match
namespace="dev"
OR
namespace!="dev"
.
Task 5: One rule setup for a Team
We have two teams, Team A and Team B. Loki access is setup with Editor
, Viewer
roles to have Query
permission.
Team A has a rule
namespace="dev"
configured.Team B does not have a rule configured for it.
A user that is part of Team A will have access to logs that match namespace="dev"
.
A user that is part of Team A and part of Team B will have access to logs that match namespace="dev"
.
A user that is not part of Team A and part of Team B, that is Editor
or Viewer
will have access to all logs (due to the query permission for the user).
