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.

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.

Get permissions​

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

Use the permissions subcommand and specify a namespace:


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

Revoke permissions​

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

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
