A host machine operated for a specific purpose can have restricted access to other components in a multi-tenant environment in order to provide for the security of the host machine. The access restriction can prevent the host machine from obtaining updates to critical system-level configurations, but such information can be obtained through a signed command received to an API for the host machine. The command can be signed by a quorum of operators, and the host machine can be configured to verify the signatures and the quorum before processing the command. The host machine can store the updates to ephemeral storage as well as persistent storage, such that upon a reboot or power cycle the host machine can operate with current configuration data.

Configuration updates for access-restricted hosts

Dynamic task discovery may be implemented for performing workflow tasks. Input may be received from a workflow engine via static interface upon which a task may be performed that is part of a workflow. A version of the task may be dynamically determined according to dynamic task configuration data. The discovered version of the task may be performed and output notification of completion may be sent to the workflow engine. In some embodiments, the dynamic configuration for a task may be modified such that one performance of the task in a workflow may be according to a different version of the task than another performance the same task in the same workflow. In some embodiments, task templates with dynamically discoverable tasks may be generated by a workflow engine service in order to be implemented as tasks in a workflow.
