The following tips will help ensure proper Tungsten Cluster operations and security, along with a smooth Dashboard user experience:
Do not share user accounts.
Use namespaces for your clusters.
When performing actions or investigating a cluster, use the manual lock to prevent other users from changing the cluster at the same time.
Install the Dashboard behind an SSL proxy and only use the Dashboard with SSL.
If you experience connection difficulties with the Dashboard and a given cluster:
Try to be patient since the Dashboard has a 60-second timeout by default.
Adding the same cluster multiple times or running the same action multiple times can have unpredictable consequences
Prefer SSL connections to clusters whenever reasonable and possible.
To retain cluster performance:
Avoid multiple Dashboard instances being connected to the same cluster or rapid startup and shut down cycles to the same Dashboard instance.
Clusters clean connections periodically but not instantly, avoid situations where you generate several connections from the Dashboard(s) to the cluster in a short period of time.
Prefer single long-running instances over rapidly-cycling ones.
If you persist data for version updates or restart the cluster, make sure that you use the same DASHBOARD_SECRET
in the new instance of the Dashboard, otherwise you might lose accesss to your encrypted data.
