rancher/agent + rancher/server on the same box

[Luca G. Soave]

Hi there,

having many docker containers running on my laptop as a 3-tier app,
I'd like to import them all to rancher/server on the same laptop box (outside Vagrant).

I started both the agent and the server on my laptop :

lsoave@basenode:~$ docker ps
CONTAINER ID        IMAGE                   COMMAND                CREATED             STATUS              PORTS                              NAMES
39ffc6af91f8        rancher/agent:v0.5.2    "/run.sh http://127.   18 minutes ago      Up 6 minutes                                           trusting_meitner   
3b76c33f3e12        rancher/server:latest   "/usr/bin/s6-svscan    39 minutes ago      Up 39 minutes       3306/tcp, 0.0.0.0:8080->8080/tcp   cocky_lumiere      

but "localhost" never join the server as a new host of course, because of the different network i guess, infact the agent log says:

lsoave@basenode:~$ docker logs 39ffc6af91f8
ERROR: http://10.36.36.91/v1 is not accessible
ERROR: Could not reach http://10.36.36.91/v1. Giving up.

while the server log says :

lsoave@basenode:~$ docker logs -f 3b76c33f3e12
time="2015-04-21T20:41:54Z" level=error msg="Unable to create EventRouter" Err="Get http://127.0.0.1/v1: dial tcp 127.0.0.1:80: connection refused"
time="2015-04-21T20:41:54Z" level=info msg="Exiting go-machine-service..."

any idea about how to config that (without Vagrant support) ?

Hi Luca, 

What command did you execute to run the agent container?  From the brief logs you've shown, it looks like you may have registered your host IP wrong after you attempted to "Add Host".  It looks like you may have specified 127.0.0.1:80 as your host for your agents to connect to but it's listening on port 8080.

I just followed custom provider Add Host instructions in my rancher/server dashboard ( http://127.0.0.1:8080/static/hosts/add/custom ) at step 3:

Copy, paste, and run the command below to register the host with Rancher:
sudo docker run -d --privileged -v /var/run/docker.sock:/var/run/docker.sock rancher/agent:v0.5.2 http://127.0.0.1/v1/scripts/11C598D0FE2F04666DC5:1429732800000:epL7Smr8yCs1XxgR4wtdVS08ve4

... anyway I tried adding 8080 port :

sudo docker run -d --privileged -v /var/run/docker.sock:/var/run/docker.sock rancher/agent:v0.5.2 http://127.0.0.1:8080/v1/scripts/11C598D0FE2F04666DC5:1429732800000:epL7Smr8yCs1XxgR4wtdVS08ve4

what I got is the agent(s) exited :

lsoave@basenode:~$ docker ps -a

the server log was the same as before :

time="2015-04-22T21:56:12Z" level=error msg="Unable to create EventRouter" Err="Get http://127.0.0.1/v1: dial tcp 127.0.0.1:80: connection refused"

time="2015-04-22T21:56:12Z" level=info msg="Exiting go-machine-service..."

this last it seems to me just a parsing/truncation typo/bug but I don't know really ...

...  docker version was:

lsoave@basenode:~$ docker -v
Docker version 1.6.0, build 4749651

HI Luca, 

It looks like someone else might be experiencing the same issue as you as described here.
