Setup Error / Unexpected end of JSON input #15

Hello all,

I'm having some trouble deploying out to Rackspace (RackConnect v3) using the rackconnect-v3 yaml.

Here is the error I am getting from the overlord after deployment:

Any help would be appreciated! Thanks for this repo.

@cedbossneo is/was the maintainer for the rackconnect template. corekube has been updated quite a bit since the rackconnect template was last touched.

hoping @cedbossneo can chime in and possibly update it, if not, i can examine it

nnnnathann commented 9 years ago

FYI, I gave it another shot by just updating the commit hash for overlord in the rackconnect file, thinking maybe it was just a version mismatch issue. That failed also for a different reason

Probably going to stop here for now and await response, thanks so much for the help!

Also, I wouldn't mind diving in myself if you all have an idea of where to start? I'm new to a lot of things but might be able to help out with a pointer in the right direction?

Again, thanks for the time and the effort to set up this repo!

@nnnnathann your best bet is to take the corekube-rackconnect-v3.yaml (https://github.com/metral/corekube/blob/master/corekube-rackconnect-v3.yaml) and adapt it to model the corekube-cloudservers.yaml (https://github.com/metral/corekube/blob/master/corekube-cloudservers.yaml) as closely as possible. come to think of it, given that there are extra network interfaces on public cloud, the yaml file for rackconnect will probably resemble that of OnMetal (https://github.com/metral/corekube/blob/master/corekube-onmetal.yaml).

I'd start on that path and see how far it gets you. Unfortunately, I can't be of much help for RackConnect as I don't have an account to use in that environment but I can provide feedback & guidance if needed.

Please keep us posted

Hi, sorry i wasnt available last week,

I've release a updated version of the heat file but i can't test it right now, if you want to try : https://github.com/cedbossneo/corekube/tree/update-heat-file

nnnnathann commented 9 years ago

It appears to have worked!

Thank you both.

metral commented 9 years ago

closing due to the issue being resolved

nnnnathann commented 9 years ago

No big deal, but I think this is not resolved technically until the aforementioned rackconnect heat file is merged?

https://github.com/cedbossneo/corekube/blob/update-heat-file/corekube-rackconnect-v3.yaml

Thanks everyone

metral commented 9 years ago

@nnnnathann it was merged yesterday: https://github.com/metral/corekube/pull/17

is there something missing?

nnnnathann commented 9 years ago

ha, nope, I'll see myself out. thanks again

metral commented 9 years ago

Haha no worries. Please let us know if you encounter any other issues with Corekube
