Return Codes¶

When the salt or salt-call CLI commands result in an error, the command will exit with a return code of 1. Error cases consist of the following:

Errors are encountered while running States, or any state returns a False result
Any exception is raised
In the case of remote-execution functions, when the return data is a Python dictionary with a key named either result or success, which has a value of False

Retcode Passthrough¶

In addition to the cases listed above, if a state or remote-execution function sets a nonzero value in the retcode key of the __context__ dictionary, the command will exit with a return code of 1. For those developing custom states and execution modules, using __context__['retcode'] can be a useful way of signaling that an error has occurred:

if something_went_wrong:
    __context__["retcode"] = 42

This is actually how states signal that they have failed. Different cases result in different codes being set in the __context__ dictionary:

1 is set when any error is encountered in the state compiler (missing SLS file, etc.)
2 is set when any state returns a False result
5 is set when Pillar data fails to be compiled before running the state(s)

When the --retcode-passthrough flag is used with salt-call, then salt-call will exit with whichever retcode was set in the __context__ dictionary, rather than the default behavior which simply exits with 1 for any error condition.
