Hi, |

Hi, |
|
First of all cocaine-tools < 12 doesn't work with cocaine > 12 :) you could install it directly from master branch github.com/cocaine/cocaine-tools. When it comes to cocaine-runtime do you build it from source? |
|
Oh, thank you, I will try :). |
|
Now, it seems works, at least I have tried to follow the docs, step-by-step, but it doesn't work correctly. From Uploading package - looks good: Uploading profile: Starting app: |
|
Hello again! "services": {
"node": {
"type": "node::v2",
"args": {
"runlist": "default"
}
}, |

Hi, I have reinstalled What it could be? The cocaine-runtime instantly finishes: The configuration file: If remove Thanks! |
|
Could you provide me logs from syslog about cocaine-runtime, please? |
|
Here is: |

As we can see plugin for service node is not available. Did you install it? If you just buit from source and ran |
|
Hi, now, it works, I can see that the app is executing on the node. But, the last thing (I hope), how to send the request to this app and get the response? But, it produce error: I have checked the sources of Service, and found out that, probably the way of communication described in the docs is a bit obsoleted. Could you advise, what I do wrong? |

There're some changes from v0.11 to v0.12. You installed cocaine-framework-python for 0.12, right? #!/usr/bin/env python
from tornado import gen
from tornado.ioloop import IOLoop
from cocaine.services import Service
io = IOLoop.current()
import os
@gen.coroutine
def f():
# create service
service = Service("Echo")
# create new output stream to app with enqueue method
channel = yield service.enqueue("doIt")
# send one chunk of data to the app
yield channel.tx.write("SomeMessage")
# get one chunk from the app
res = yield channel.rx.get()
print res
channel.tx.close()
io.run_sync(f, timeout=10) |

Now it works! Thank you! 👍 I have tried on another machine, seems it works, but it can't communicate with the client app, |

I guess a wrong version of framework is installed on the machine, for example. I'm not sure if your syslog is tuned to not to filter debug messages out. If no messages with [D] appear in syslog after that, we can try to log to a file or stderr: So first of all, check the version of python-framework on the server (astor-034-p5j). |

Hi! Thank you! I have managed to install and run it on the another machine, the libs and other stuff were in a mess. To summarize the steps of installation: |

I think, we should fix the guide. Thanks! |

I think installation on OpenSuse is also related to the issue. So, here is a small guide if someone looking. Installation Cocaine on OpenSuse from sourcesCocaine CoreInstall required libraries: sudo zypper in devscripts autoconf automake libtool

I have installed
cocaineandcocaine-tools, and tried to install the example ( https://github.com/cocaine/cocaine-framework-python/wiki/Echo-application-example ). When I runcocaine-runtimeas non-daemon with the following configuration file ( other sections are the same as in /cocaine-core/debian/cocaine-runtime.conf ):It seems that it works:
On the other session, I run cocaine-tools and try to upload example app as it is proposed in docs, and after execution of cocaine-tool profile upload, it stucks, to execute next command I need terminate current cocaine-tools process. Moreover, no feedback from
cocaine-runtime.Could you please advise what I do wrong, and how to configure it properly?
Thanks!
