Fabio is not adding route, but health check is passing

Here is the information I have:

GitHub issue Fabio

Service and healthcheck (/etc/consul.d/helloworld.json):

{
    "service": {
        "name": "helloworld",
        "tags": [
            "urlprefix-/hello"
        ],
        "port": 80
    },
    "check": {
        "id": "helloworld",
        "name": "HTTP helloworld on port 80",
        "http": "http://localhost",
        "interval": "10s",
        "timeout": "1s"
    }
}

App service

docker run -d -p80:80 tutum/hello-world

Extra check:

dig @127.0.0.1 -p 8600 helloworld.service.consul
;; ANSWER SECTION:
helloworld.service.consul. 0    IN      A       some.ip.address.here

No route add event occurs in my fabio logs and it definitely doesn't show up on localhost:9888/routes. Am I missing something obvious?

Try setting a service id.

[magiconair]

and make sure it is unique per instance. Typical is helloworld-host:port

[artburkart]

Not sure where I got the idea that my config was correct, but it definitely was not. This was sufficient:

{
    "service": {
        "name": "helloworld",
        "tags": [
            "urlprefix-/hello"
        ],
        "port": 80,
        "check": {
            "http": "http://localhost",
            "interval": "10s",
            "timeout": "1s"
        }
    }
}

Thank you for your assistance. The fact that the ServiceId was not being defined was because my config was no good. By default, it takes the value in the name field, but I must've fallen into some "undefined behavior" land.

[magiconair]

No worries. You are not the first one with this problem. It is either the missing health check or the missing/non-unique service id. That's why these things are also the first items in the README and Quickstart ;)

[magiconair]

Closing for now. Feel free to re-open or to ask more questions.

I just stumbled upon this issue since I had a space within the consul service name. I wasn't expecting fabio to use the service name for route add. Service ID and check ID were unique (and without spaces).

Maybe this should be noted within the Quickstart?

[magiconair]

@lennart That's a good point. If I would use the service id instead of the name then it would be more difficult to implement weighted routing. I could also update the parser to allow services with names and then quote the name.

[magiconair]

@lennart Updated both the Quickstart and the README.

Added #373 to track this.
