Current version: 0.1.0
thar-be-updates is a Bottlerocket update dispatcher that serves as an interface for the apiserver to issue update commands and monitor update status.
It models the Bottlerocket update process after a state machine and provides several update commands that modifies the update state.
It keeps track of the update state and other stateful update information in a update status file located at /run/update-status
Upon receiving a command not allowed by the update state, thar-be-updates exits immediately with an exit status indicating so.
Otherwise, thar-be-updates forks a child process to spawn the necessary process to do the work.
The parent process immediately returns back to the caller with an exit status of 0.
The output and status of the command will be written to the update status file.
This allows the caller to synchronously call thar-be-updates without having to wait for a result to come back.
thar-be-updates uses a lockfile to control read/write access to the disks and the update status file.
