OPC Publisher configuration via command line options and environment variables

Home

This documentation applies to version 2.9

The following OPC Publisher configuration can be applied by Command Line Interface (CLI) options or as environment variable settings. Any CamelCase options can also be provided using environment variables (without the preceding --). When both environment variable and CLI argument are provided, the command line option will override the environment variable.

IMPORTANT: The command line of OPC Publisher only understands below command line options. You cannot specify environment variables on the command line (e.g., like env1=value env2=value). All option names are case-sensitive!

Secrets such as EdgeHubConnectionString, other connection strings, or the ApiKey should never be provided on the command line or as environment variables. It should be avoided at all cost. A file using the .env format can be specified using the ADDITIONAL_CONFIGURATION environment variable. The contents will be loaded before the command line arguments are evaluated. If a file name is not provided via said environment variable, OPC Publisher tries to load the /run/secrets/.env file. This approach integrates well with docker secrets. An example of this can be found here.

Please note that rolling of secrets is not supported and that any errors loading secrets is silently discarded.

  -h, --help                 Show help and exit.
  -f, --pf, --publishfile, --PublishedNodesFile=VALUE
                             The name of the file containing the configuration
                               of the nodes to be published as well as the
                               information to connect to the OPC UA server
                               sources.
                               This file is also used to persist changes made
                               through the control plane, e.g., through IoT Hub
                               device method calls.
                               When no file is specified a default `
                               publishednodes.json` file is created in the
                               working directory.
                               Default: `publishednodes.json`
      --cf, --createifnotexist, --CreatePublishFileIfNotExistKey[=VALUE]
                             Permit publisher to create the the specified
                               publish file if it does not exist. The new file
                               will be created under the access rights of the
                               publisher module.
                               The default file 'publishednodes.json' is always
                               created when no file name was provided on the
                               command line and this option is ignored.
                               If a file was specified but does not exist and
                               should not be created the module exits.
                               Default: `false`
      --fe, --forceencryptedcredentials, --ForceCredentialEncryption[=VALUE]
                             If set to true the publisher will never write
                               plain text credentials into the published nodes
                               configuration file.
                               If a credential cannot be written to the file
                               using the IoT Edge workload API crypto provider
                               the publisher will exit with an error.
                               Default: `false` (write secrets as plain text
                               into the configuration file which should be
                               properly ACL'ed)
      --id, --publisherid, --PublisherId=VALUE
                             Sets the publisher id of the publisher.
                               Default: `not set` which results in the IoT edge
                               identity being used
  -s, --site, --SiteId=VALUE Sets the site name of the publisher module.
                               Default: `not set`
      --rs, --runtimestatereporting, --RuntimeStateReporting[=VALUE]
                             Enable that when publisher starts or restarts it
                               reports its runtime state using a restart
                               message.
                               Default: `False` (disabled)
      --api-key, --ApiKey=VALUE
                             Sets the api key that must be used to authenticate
                               calls on the publisher REST endpoint.
                               Default: `not set` (Key will be generated if not
                               available)
      --doa, --disableopenapi, --DisableOpenApiEndpoint[=VALUE]
                             Disable the OPC Publisher Open API endpoint
                               exposed by the built-in HTTP server.

                             Use strict OPC UA standard compliance. It is
                               recommended to run the publisher in compliant
                               mode for best interoperability.
                               Be aware that explicitly specifying other
                               command line options can result in non-
                               comnpliance despite this option being set.
                               Default: `False` for backwards compatibility (2.

                               Default: `PubSub` if `-c` is specified,
                               otherwise `Samples` for backwards compatibility.
      --ode, --optimizeddatasetencoding, --WriteValueWhenDataSetHasSingleEntry[=VALUE]
                             When a data set has a single entry the encoder
                               will write only the value of a data set entry
                               and omit the key.
                               This is not compliant with OPC UA Part 14.
                               Default: `False`.
      --me, --messageencoding, --MessageEncoding=VALUE

                                   `IsGzipCompressed`
                                   `JsonGzip`
                                   `JsonReversibleGzip`
                               Default: `Json`.
      --bi, --batchtriggerinterval, --BatchTriggerInterval=VALUE
                             The network message publishing interval in
                               milliseconds. Determines the publishing period
                               at which point messages are emitted.
                               When `--bs` is 1 and `--bi` is set to 0 batching
                               is disabled.
                               Default: `10000` (10 seconds).
                               Also can be set using `BatchTriggerInterval`
                               environment variable in the form of a duration
                               string in the form `[d.]hh:mm:ss[.fffffff]`.
      --bs, --batchsize, --BatchSize=VALUE
                             The number of incoming OPC UA subscription
                               notifications to collect until sending a network
                               messages. When `--bs` is set to 1 and `--bi` is
                               0 batching is disabled and messages are sent as
                               soon as notifications arrive.
                               Default: `50`.
      --rdb, --removedupsinbatch, --RemoveDuplicatesFromBatch[=VALUE]
                             Use this option to remove values with the same
                               node id from batch messages in legacy `Samples`
                               mode. Sends only the latest value as per the
                               value's source timestamp.
                               Only applies to `Samples` mode, otherwise this
                               setting is ignored.
                               Default: `False` (keep all duplicate values).
      --ms, --maxmessagesize, --iothubmessagesize, --IoTHubMaxMessageSize=VALUE
                             The maximum size of the messages to emit. In case
                               the encoder cannot encode a message because the
                               size would be exceeded, the message is dropped.
                               Otherwise the encoder will aim to chunk messages
                               if possible.
                               Default: `256k` in case of IoT Hub messages, `0`
                               otherwise.

                             The default quality of service to use for data set
                               messages.
                               This does not apply to metadata messages which
                               are always sent with `AtLeastOnce` semantics.
                               Allowed values:
                                   `AtMostOnce`
                                   `AtLeastOnce`
                                   `ExactlyOnce`
                               Default: `AtLeastOnce`.
      --mts, --messagetimestamp, --MessageTimestamp=VALUE
                             The value to set as as the timestamp property of
                               messages during encoding (if the encoding
                               supports writing message timestamps).
                               Allowed values:
                                   `CurrentTimeUtc`
                                   `PublishTime`
                                   `EncodingTimeUtc`
                               Default: `CurrentTimeUtc` to use the time when
                               the message was created in OPC Publisher.
      --npd, --maxnodesperdataset, --MaxNodesPerDataSet=VALUE
                             Maximum number of nodes within a Subscription.
                               When there are more nodes configured for a data
                               set writer, they will be added to new
                               subscriptions. This also affects metadata
                               message size.
                               Default: `1000`.
      --kfc, --keyframecount, --DefaultKeyFrameCount=VALUE
                             The default number of delta messages to send until
                               a key frame message is sent. If 0, no key frame
                               messages are sent, if 1, every message will be a
                               key frame.
                               Default: `0`.
      --ka, --sendkeepalives, --EnableDataSetKeepAlives[=VALUE]
                             Enables sending keep alive messages triggered by
                               writer subscription's keep alive notifications.
                               This setting can be used to enable the messaging
                               profile's support for keep alive messages.
                               If the chosen messaging profile does not support
                               keep alive messages this setting is ignored.
                               Default: `False` (to save bandwidth).
      --eip, --immediatepublishing, --EnableImmediatePublishing[=VALUE]
                             By default OPC Publisher will create a
                               subscription with publishing disabled and only
                               enable it after it has filled it with all
                               configured monitored items. Use this setting to
                               create the subscription with publishing already
                               enabled.
                               Default: `False`.
      --msi, --metadatasendinterval, --DefaultMetaDataUpdateTime=VALUE
                             Default value in milliseconds for the metadata
                               send interval which determines in which interval
                               metadata is sent.
                               Even when disabled, metadata is still sent when
                               the metadata version changes unless `--mm=*
                               Samples` is set in which case this setting is
                               ignored. Only valid for network message
                               encodings.
                               Default: `0` which means periodic sending of
                               metadata is disabled.
      --dm, --disablemetadata, --DisableDataSetMetaData[=VALUE]
                             Disables sending any metadata when metadata
                               version changes. This setting can be used to
                               also override the messaging profile's default
                               support for metadata sending.
                               It is recommended to disable sending metadata
                               when too many nodes are part of a data set as
                               this can slow down start up time.
                               Default: `False` if the messaging profile
                               selected supports sending metadata and `--strict`
                                is set but not '--dct', `True` otherwise.
      --amt, --asyncmetadatathreshold, --AsyncMetaDataLoadThreshold=VALUE
                             The default threshold of monitored items in a
                               subscription under which meta data is loaded
                               synchronously during subscription creation.
                               Loaded metadata guarantees a metadata message is
                               sent before the first message is sent but
                               loading of metadata takes time during
                               subscription setup. Set to `0` to always load
                               metadata asynchronously.
                               Only used if meta data is supported and enabled.
                               Default: `30`.
      --dsg, --disablesessionpergroup, --DisableSessionPerWriterGroup[=VALUE]
                             Disable creating a separate session per writer
                               group. Instead sessions are re-used across
                               writer groups.
                               Default: `False`.
      --om, --maxsendqueuesize, --MaxNetworkMessageSendQueueSize=VALUE
                             The maximum number of messages to buffer on the
                               send path before messages are dropped.
                               Default: `4096`
      --wgp, --writergrouppartitions, --DefaultWriterGroupPartitionCount=VALUE
                             The number of partitions to split the writer group
                               into. Each partition represents a data flow to
                               the transport sink. The partition is selected by
                               topic hash.
                               Default: `0` (partitioning is disabled)
  -t, --dmt, --defaultmessagetransport, --DefaultTransport=VALUE
                             The desired transport to use to publish network
                               messages with.
                               Requires the transport to be properly configured
                               (see transport settings).
                               Allowed values:
                                   `IoTHub`

                               is sent to the same output as regular messages.
                               If specified without value, the default output
                               is `{TelemetryTopic}/metadata`.
      --uns, --datasetrouting, --DefaultDataSetRouting=VALUE
                             Configures whether messages should automatically

                               RootFolder.
                               The browse path is appended as topic structure
                               to the telemetry topic root which can be
                               configured using `--ttt`. Reserved characters in
                               browse names are escaped with their hex ASCII
                               code.

                               in the configuration.
                               Note: This has high impact on OPC Publisher
                               startup performance.
                               Default: `False` (disabled).

                               the discard old setting of monitored item queue
                               configuration. Setting to true will ensure that
                               new values are dropped before older ones are
                               drained.

                               without a skip first setting. A value of True
                               will skip sending the first notification
                               received when the monitored item is added to the
                               subscription.

                               seconds for the heartbeat interval setting of
                               nodes that were configured without a heartbeat
                               interval setting. A heartbeat is sent at this
                               interval if no value has been received.
                               Default: `0` (disabled)

                               This setting not just disables meta data
                               messages but also prevents transcoding of
                               unknown complex types in outgoing messages.
