{code}
We are upgrading to get the Announcer implementation working. Here's a simple
task config that has no {{constraints}} and still produces the error (we
haven't been able to generate a {{.aurora}} config that doesn't result in this
exception.
{code}
drag_proc_0 = Process(
name = 'drag_proc_0',
cmdline = """
while sleep 1; do date; done
"""
)
drag_task = Task(
processes = [drag_proc_0],
resources = Resources(cpu = 0.5, ram = 1*GB, disk = 1*GB)
)
jobs = [
Service(
task = drag_task,
cluster = 'staging',
role = 'produser',
environment = 'staging',
name = 'drag',
instances = 1,
update_config = UpdateConfig(batch_size = 1, watch_secs = 345,
rollback_on_failure = False, max_per_shard_failures = 3),
)
]
