Managing permissions

Permissions in Pulsar are managed at the namespace level(that is, within tenants and clusters).

Grant permissions

You can grant permissions to specific roles for lists of operations such as produce and consume.

pulsar-admin

Use the grant-permission subcommand and specify a namespace, actions using the —actions flag, and a role using the —role flag:

$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
  --actions produce,consume \
  --role admin10

Wildcard authorization can be performed when authorizationAllowWildcardsMatching is set to true in broker.conf.

e.g.

$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
                        --actions produce,consume \
                        --role 'my.role.*'

Then, roles my.role.1, my.role.2, my.role.foo, my.role.bar, etc. can produce and consume.

$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
                        --actions produce,consume \
                        --role '*.role.my'

Then, roles 1.role.my, 2.role.my, foo.role.my, bar.role.my, etc. can produce and consume.

Note: A wildcard matching works at the beginning or end of the role name only.

e.g.

$ pulsar-admin namespaces grant-permission test-tenant/ns1 \
                        --actions produce,consume \
                        --role 'my.*.role'

In this case, only the role my..role has permissions.Roles my.1.role, my.2.role, my.foo.role, my.bar.role, etc. *cannot produce and consume.

REST API

POST/admin/v2/namespaces/:tenant/:namespace/permissions/:role

Java

admin.namespaces().grantPermissionOnNamespace(namespace, role, getAuthActions(actions));

Get permissions

You can see which permissions have been granted to which roles in a namespace.

pulsar-admin

Use the permissions subcommand and specify a namespace:

$ pulsar-admin namespaces permissions test-tenant/ns1
{
  "admin10": [
    "produce",
    "consume"
  ]
}   

REST API

GET/admin/v2/namespaces/:tenant/:namespace/permissions

Java

admin.namespaces().getPermissions(namespace);

Revoke permissions

You can revoke permissions from specific roles, which means that those roles will no longer have access to the specified namespace.

pulsar-admin

Use the revoke-permission subcommand and specify a namespace and a role using the —role flag:

$ pulsar-admin namespaces revoke-permission test-tenant/ns1 \
  --role admin10

REST API

DELETE/admin/v2/namespaces/:tenant/:namespace/permissions/:role

Java

admin.namespaces().revokePermissionsOnNamespace(namespace, role);
