Eucalyptus Configuration Variables

Eucalyptus exposes a number of variables that can be configured using the command. This topic explains what types of variables Eucalyptus uses, and lists the most common configurable variables.

Eucalyptus Variable Types

Eucalyptus uses two types of variables: ones that can be changed (as configuration options), and ones that cannot be changed (they are displayed as variables, but configured by modifying the eucalyptus.conf file on the CC).

Once a cloud is in use and has started operating based on these variables, it is not safe to change them at runtime.

Eucalyptus Variables

The following table contains a list of common Eucalyptus cloud variables.

tokens.disabledactions Actions to disable
tokens.enabledactions Actions to enable (ignored if empty)
tokens.rolearnaliaswhitelist Permitted account aliases for role Amazon Resource Names (ARNs). Value is a list, for example: eucalyptus,aws,dev*,prod* in the case where multiple aliases are permitted. Default: eucalyptus
tokens.webidentityoidcdiscoverycache Cache settings for discovered OpenID Connect metadata: provider configuration and keys. Works with tokens.webidentityoidcdiscoveryrefresh. Default: maximumSize=20, expireAfterWrite=15m
tokens.webidentityoidcdiscoveryrefresh OpenID Connect discovery cache refresh expiry. Controls the time in seconds between checks for updated OIDC metadata. Works with tokens.webidentityoidcdiscoverycache. Default: 60

tokens.webidentitytokenskew A clock skew value in seconds. The Web identity token expiry / not before validation is allowed within the configured skew. Default: 60
walrusbackend.storagedir Path to buckets storage
ZONE.storage.blockstoragemanager EBS Block Storage Manager to use for backend
ZONE.storage.cephconfigfile Absolute path to Ceph configuration (ceph.conf) file. Default value is ‘/etc/ceph/ceph.conf’
ZONE.storage.cephkeyringfile Absolute path to Ceph keyring (ceph.client.eucalyptus.keyring) file. Default value is ‘/etc/ceph/ceph.client.eucalyptus.keyring’
ZONE.storage.cephsnapshotpools Ceph storage pool(s) made available to Eucalyptus for EBS snapshots. Use a comma separated list for configuring multiple pools. Default value is ‘rbd’
ZONE.storage.cephuser Ceph username employed by Eucalyptus operations. Default value is ‘eucalyptus’
ZONE.storage.cephvolumepools Ceph storage pool(s) made available to Eucalyptus for EBS volumes. Use a comma separated list for configuring multiple pools. Default value is ‘rbd’
ZONE.storage.chapuser User ID for CHAP authentication
ZONE.storage.dasdevice Direct attached storage device location
ZONE.storage.maxconcurrentsnapshots Maximum number of snapshots processed on the block storage backend at a given time
ZONE.storage.maxconcurrentsnapshottransfers Maximum number of snapshots that can be uploaded to or downloaded from objectstorage gateway at a given time
ZONE.storage.maxconcurrentvolumes Maximum number of volumes processed on the block storage backend at a given time
ZONE.storage.maxsnapshotdeltas A non-zero integer value enables upload of incremental snapshots when possible. The configured value indicates the SC to create/upload that many snapshot deltas for a given EBS volume before triggering a full upload of the snapshot contents. Between any two consecutive full snapshot uploads for a given EBS volume, there will be at most maxsnapshotdeltas number of incremental snapshot uploads. A value of 0 indicates that a newly created snapshot will always be uploaded in its entirety (that is, no deltas). Snapshot deltas are only used when your backend is Ceph-RBD. ZONE.storage.shouldtransfersnapshots must be set to true to enable snapshot deltas.Default: 0
ZONE.storage.maxsnapshotpartsqueuesize Maximum number of snapshot parts per snapshot that can be spooled on the disk
ZONE.storage.maxtotalvolumesizeingb Total disk space reserved for volumes
ZONE.storage.maxvolumesizeingb Max volume size
ZONE.storage.ncpaths iSCSI Paths for NC. Default value is ‘nopath’
ZONE.storage.readbuffersizeinmb Buffer size in MB for reading data from snapshot when uploading snapshot to objectstorage gateway
ZONE.storage.resourceprefix Prefix for resource name on SAN
ZONE.storage.resourcesuffix Suffix for resource name on SAN
ZONE.storage.sanhost Hostname for SAN device.
ZONE.storage.sanpassword Password for SAN device.
ZONE.storage.sanuser Username for SAN device.
ZONE.storage.scpaths iSCSI Paths for SC. Default value is ‘nopath’
ZONE.storage.shouldtransfersnapshots Enable snapshot transfer to the OSG. Setting it to false will disable storing snapshots (full or delta) in object storage. While a false setting will reduce object storage requirements, it also prevents the ability to use a snapshot from one availability zone to create a volume in another zone. You can still take/use snapshots even when the setting is false, but you can only use a snapshot to create a volume in the same zone. Must be set to true to use snapshot deltas, which are managed by the ZONE.storage.maxsnapshotdeltas property.Default: true
ZONE.storage.snapexpiration Time interval in minutes after which Storage Controller metadata for snapshots that have been physically removed from the block storage backend will be deleted
ZONE.storage.snapshotpartsizeinmb Snapshot part size in MB for snapshot transfers using multipart upload. Minimum part size is 5MB
ZONE.storage.snapshottransfertimeoutinhours Snapshot upload wait time in hours after which the upload will be cancelled
ZONE.storage.storeprefix Prefix for ISCSI device
ZONE.storage.tid Next Target ID for ISCSI device
ZONE.storage.timeoutinmillis Timeout value in milli seconds for storage operations
ZONE.storage.volexpiration Time interval in minutes after which Storage Controller metadata for volumes that have been physically removed from the block storage backend will be deleted
ZONE.storage.volumesdir Storage volumes directory.
ZONE.storage.writebuffersizeinmb Buffer size in MB for writing data to snapshot when downloading snapshot from object storage gateway
ZONE.storage.zerofillvolumes Should volumes be zero filled.
