weave launch not functioning on the latest docker for mac

[the-destro]

The latest beta is throwing an error on weave launch:
unable to create network: API error (500): invalid ipam driver: "weavemesh"

[errordeveloper]

Just for the record, are we talking about 1.12.0-rc2-beta16?

[errordeveloper]

I can confirm this is the case on Docker for Mac version 1.12.0-rc2-beta16. @rade have we tested Docker plugin on 1.12.0-rc2 in general? Docker for Mac ships vanilla builds, as far as I am aware.

[errordeveloper]

@the-destro is this in connection with kubernetes-retired/kubernetes-anywhere#138 that you have reported earlier?

[rade]

have we tested Docker plugin on 1.12.0-rc2 in general?

We've run our entire test suite against 1.12.0-rc1, iirc.

[errordeveloper]

One thing I just realised is that I was testing this using Weave Net 1.5.2. Having tested with latest 1.6.0, I can confirm that this issue only occurs on Docker for Mac 1.12.0-rc2-beta16 and with Weave Net 1.5.2. I doesn't occur with Weave 1.5.2 on Boot2Docker 1.12.0-rc2. All works well with Docker for Mac and Weave Net 1.6.0.

[errordeveloper]

@the-destro please upgrade to Weave Net 1.6.0.

I'm having the same issue running on Linux (Centos 7):

[errordeveloper]

I wonder what may be in common between Moby (the Alpine derivative used in
Docker for Mac) and CentOS?

@mongrelion currently I'm not able to reproduce this with either versions (1.5.2 and 1.6.0). Can you reproduce it consistently?

[errordeveloper]

@mongrelion if you can reproduce it, please use weave launch --log-level=debug and provide the output of docker logs weaveplugin.

[mongrelion]

@errordeveloper sorry, I can't seem to reproduce it anymore. I'm currently trying it all out in a Vagrant machine which I created last night and ran into that issue.
I just recreated the machine (Docker & Weave installation steps are automated) and can't seem to reproduce the error anymore. I'm running into other issues but those are off topic for this thread.
Sorry about the fuzz.

[errordeveloper]

@mongrelion ok, so I am suspecting it could be a race condition in Docker plugins API. Could you share the Vagrantfile, and I'll try to run it in a loop for a while?

[mongrelion]

@errordeveloper here you go.
Heads up: you'll need Ansible installed. Ping me on Slack if you need help with that.

[errordeveloper]

I ran the following in that directory:

while true; do (make destroy ; make up) && vagrant ssh -c "weave launch && weave status" ; [ "$?" -ne 0 ] && break || continue ; do

The error didn't come up in 26 iterations.

[rade]

I am seeing this error after docker swarm init. See #2403.

@the-destro @mongrelion did you perhaps run docker swarm init? What does docker network ls return?

[the-destro]

@rade yes I did. I have tried after leaving the swarm as well and got the same error.

[rade]

yes I did.

I which case the problem you are seeing is very likely the same as #2403.

I have tried after leaving the swarm as well and got the same error.

See #2403 (comment)

@mongrelion were you too running docker swarm init?

[mongrelion]

@rade I think I might have, yes, as I was doing tests to integrate the demo app with SwarmKit and ran into that error at some point.

[rade]

Thanks for the confirmation. I am going to close this as a dup of #2403 then.
