Saving output streams
|
||
|
|
=====================
|
||
|
|
|
||
|
|
Description
|
||
|
|
-----------
|
||
|
|
Since version 4.8.0 cdist, by default, saves output streams to local cache.
|
||
|
|
Saving output streams is implemented because important information was lost
|
||
|
|
during a config run, hidden in all other output.
|
||
|
|
Now all created output is bound to the context where it was produced.
|
||
|
|
|
||
|
|
Saving output streams include stdout and stderr of init manifest, remote
|
||
|
|
commands and for each object stdout and stderr of manifest, gencode-\* and code-\*.
|
||
|
|
Output stream files are created only if some output is produced. For more info
|
||
|
|
on these cache files see `Local cache overview <cdist-cache.html>`_.
|
||
|
|
|
||
|
|
Also, in case of an error, cdist can now exit and show all information it has
|
||
|
|
about the error.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
$ ./bin/cdist config -v -i ~/.cdist/manifest/init-output-streams $(cat ~/ungleich/data/opennebula-debian9-test )
|
||
|
|

ERROR: cdist: Failed to configure the following hosts: 185.203.112.42

|
|
|
||
|
|
Upon successful run execution state is saved to local cache and temporary
|
||
|
|
directory is removed.
|
||
|
|
In case of an error temporary directory is not removed and can be further
|
||
|
|
discovered.
|
||
|
|
|
||
|
|
There is also an option :strong:`-S/--disable-saving-output-streams` for
|
||
|
|
disabling saving output streams. In this case error reporting can look
|
||
|
|
like this:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
