Overview ¶

NanoNanostate implementation. Nanostate example:

---------------------------------------------- id: some-Nanostate descr: This describes what this Nanostate is for.

state:

  maintain-database:
	- sshrunner:
	  - stop-db: systemctl stop postgresql.service
	  - backup-db: pg-backup /var/lib/pgsql/data /opt/backups/
	  - start-db: systemctl start postgresql.service
	- somemodule:
	  keyparam: valueparam
	  keyparam2: valueparam2
	  keyparam3: valueparam3

  some-other-group:
	- sshrunner:
	  - uptime: uptime
	  - id : cat /etc/machine-id

----------------------------------------------

In the example above, three fields are required:

• id This an ID of the Nanostate. It is used for the reporting at the end.

• descr: Description of the Nanostate. Also reporting.

• state: This is the entire tree of the Nanostate structure. It has twofold tree: a group IDs with a list of modules and the params or commands below.

Currently only one module is implemented: sshrunner, which performs a series of synchronous commands in the order they were placed for orchestration purposes.

In the nanoNanostate groups are asynchronous, but the commands inside the groups are synchronous.
