Configuration & secrets
An ArangoDB cluster has lots of configuration options. Some will be supported directly in the ArangoDB Operator, others will have to specified separately.
Built-in options
All built-in options are passed to ArangoDB servers via command-line arguments configured in the Pod-spec.
Other configuration options
All command-line options of arangod
(and arangosync
) are available
by adding options to the spec.<group>.args
list of a group
of servers.
These arguments are added to th command-line created for these servers.
Secrets
The ArangoDB cluster needs several secrets such as JWT tokens TLS certificates and so on.
All these secrets are stored as Kubernetes Secrets and passed to the applicable Pods as files, mapped into the Pods filesystem.
The name of the secret is specified in the custom resource. For example:
apiVersion: "cluster.arangodb.com/v1"
kind: "Cluster"
metadata:
name: "example-arangodb-cluster"
spec:
mode: Cluster
auth:
jwtSecretName: <name-of-JWT-token-secret>
