How to continue a task when Fabric receives an error

Question

When I define a task to run on several remote servers, if the task runs on server one and exits with an error, Fabric will stop and abort the task. But I want to make fabric

Answer 1

You should set the abort_exception environment variable and catch the exception.

For example:

from fabric.api        import env
from fabric.operations import sudo

class FabricException(Exception):
    pass

env.abort_exception = FabricException
# ... set up the rest of the environment...

try:
    sudo('reboot')
except FabricException:
    pass  # This is expected, we can continue.

You can also set it in a with block. See the documentation here.
