Soracom provides a command line tool soratun that can be embedded in a device in order to easily set up and connect to the Soracom platform using Soracom Arc.

Until now, when bootstrapping a device using soratun, credentials for connecting to Soracom Arc needed to be stored in a configuration file in the device's local file system, such as arc.json, which soratun can then subsequently use to connect to Soracom Arc.

With this update, you can now pass the configuration obtained from the bootstrap process directly into soratun in order to connect to Soracom Arc without storing a credential file.

This update adds the following options:

• --dump-config for use with the soratun bootstrap command.
• --read-stdin for use with the soratun up command.

With these two options, you can now pass the configuration directly in the following way:

soratun bootstrap --dump-config | sudo soratun up --read-stdin

In addition, the following options have also been added so that optional configuration parameters can be specified together with soratun up --read-stdin:

• --additional-allowed-ips
• --mtu
• --persistent-keepalive

Note that in order to pass the configuration directly into soratun, you must use either the Bootstrap with Cellular or Bootstrap with SIM bootstrap methods. The Bootstrap with AuthKey method is not supported.

For more details, please refer to soratun Command Reference for details.

The existing soratun bootstrap command can still be used while storing the configuration locally.
