kandi X-RAY | SwarmOpt Summary
(Fine, I'll admit. The Project Structure is pretty messed up! We made it in a bit of a rush - we believe the later we deploy, the older we are, the wiser we are. Will fix this soon:) ). SwarmOpt is a Particle Swarm Optimization Library for optimizing continuous single-objective functions. The library currently features 5 in-built objective functions and requires C++11 or above. Though PSO can also be used for Discrete Optimization Problems (like classification), the current version of the library doesn't support it. Note: Because of the Database connectivity feature, the library currently supports only Linux & Unix based Operating Systems.

QUESTION
I'm attempting to run a four-node swarm from my host machine, with my machine being the manager, and three Hyper-V VMs as worker nodes.
I'm attempting to run a static web page as a service across all nodes, but keep receiving hnsCall failed in Win32: An adapter was not found
error on my host machine, and No such image
from the VMs (trying to pull the service image from private registry).
This happens when deploying a stack or using service create
.
I can, however, run the static page via container instance and it works fine.
I followed this guide to set up and create my VMs, which I suspect is where my problem arises.
The Virtual Switch that I created via the HyperV Virtual Switch Manager, named thevswitch
, is both external and set on the correct adapter. I initialized a swarm using the IPv4 of my host machine under thevswitch
for the --advertise-addr
flag, and successfully joined the VMs as worker nodes to this IP, while using the driver. Docker doesn't seem to see the virtual switch I created regardless.
ANSWER
Answered 2019-Oct-16 at 14:24For anyone who is running into a similar issue:
The issue was NOT actually network related like these error messages implied. The problem ACTUALLY ended up being that the swarm nodes (but not my host) were all using Linux containers and trying to pull a Windows-only image. They were silently throwing architecture errors -- I only found this out when I tried to pull my image directly from a node. The errors generated while deploying to the whole swarm were highly misleading.
I did not "fix" this per say. We ended up restructuring our entire solution around this fact, and the situation no longer applies.
