Aerospike Access Control

Enable security

To use Aerospike Access control you need to enable security for the Aerospike clusters.

Aerospike server 5.7.x and later

Enable security for your Aerospike clusters in aerospikeConfig section of the CR like so

  aerospikeConfig:
    .
    .
    .
    security: {}
    .
    .
    .

Aerospike server 5.6.x and prior

Enable security for your Aerospike clusters in aerospikeConfig section of the CR like so

  aerospikeConfig:
    .
    .
    .
    security: 
      enable-security: true
    .
    .
    .

Aerospike Access Control includes user, role, and privilege creation and maintenance. See the documentation for more information on Aerospike Access Control.

To manage your access controls from the operator, configure the aerospikeAccessControl section in the Aerospike cluster's Custom Resource (CR) file.

danger

Access control changes on an operator-managed Aerospike cluster reverts if made externally (e.g. using aql or asadm).

Here are a few examples for common access control tasks:

note

For these examples, assume that cluster is deployed using a file named aerospike-cluster.yaml.

Create a Role

Add a role in the roles list under aerospikeAccessControl.

sys-admin and user-admin are standard predefined roles. Here we are adding a new custom role called "profiler" which is given read privileges.

apiVersion: asdb.aerospike.com/v1beta1
kind: AerospikeCluster
metadata:
  name: aerocluster
  namespace: aerospike

spec:
  .
  .
  aerospikeAccessControl:
    roles:
      - name: profiler
        privileges:
          - read
    users:
      - name: admin
        secretName: auth-secret
        roles:
          - sys-admin
          - user-admin

Save and exit the CR file, then use kubectl to apply the change.

kubectl apply -f aerospike-cluster.yaml

Add Privileges to a Role

Add the read and read-write privileges to the profiler role in the roles list under aerospikeAccessControl.

apiVersion: asdb.aerospike.com/v1beta1
kind: AerospikeCluster
metadata:
  name: aerocluster
  namespace: aerospike

spec:
  .
  .
  aerospikeAccessControl:
    roles:
      - name: profiler
        privileges:
          - read
          - read-write
    users:
      - name: admin
        secretName: auth-secret
        roles:
          - sys-admin
          - user-admin

Save and exit the CR file, then use kubectl to apply the change.

kubectl apply -f aerospike-cluster.yaml

Remove Privileges from a Role

Remove privileges from the desired role in the roles list under aerospikeAccessControl.

Remove read-write privilege.

apiVersion: asdb.aerospike.com/v1beta1

        secretName: auth-secret
        roles:
          - sys-admin

Save and exit the CR file, then use kubectl to apply the change.

kubectl apply -f aerospike-cluster.yaml

Create a User

Create the secret for the user and add the user in the users list under aerospikeAccessControl.

Create a secret profile-user-secret containing the password for the user profiler by passing the password from the command line:

kubectl  -n aerospike create secret generic profile-user-secret --from-literal=password='userpass'

Add profileUser user with the profiler role.
