can not see new application added to the same fabio instance

[babatundebusari]

First is it possible to have fabio route multiple applications? I mean different applications with different services name and different hosts, paths and destinations on one single instance of fabio?

Basically i have one application(but multiple container services on multiple hosts) running and now want to add another application to show on the same fabio route web dashboard, but i can't see it

Did i do anything wrong or fabio cannot do this?
Thanks!

You can have as many services as you want and each service can register as many different urlprefix-host/path prefixes as you need and they don't need to be disjoint. Service A and B can both register /foo. We've had a use case where a service was registering the URL for each individual page separately. I wouldn't recommend this but it was possible to do some service migration there.

The usual issues if you don't see a route in fabio are:

1. your service does not have a health check
2. the health check is not green (not the serf health check)
3. multiple instances of the same service are not registered with the same id, e.g. two redis instances registered with id:redis name:redis instead of id:redis1 name:redis and id:redis2 name:redis

Could you post the output of

curl localhost:8500/v1/catalog/service/<service>?pretty and curl localhost:8500/v1/health/service/<service>?pretty for the service in question?

I think there is an issue with either consul or registrator because i have services for example named wordpress-1 and mysql-1 but on consul it is seen as wordpress and mysql respectively

I think that may be the reason why fabio not seeing it.

This service has correct service name on consul and it is seen under fabio route

BUT this is the one i cannot see under fabio routes and consul has name wrong, should be wordpress-1 but consul sees it as wordpress

ok i have tested with other apps and issue seems to be with registrator and/or consul
they are not registering the correct services name.

Thanks

[magiconair]

Your service tags do not begin with urlprefix-

[babatundebusari]

@magiconair

oh i see, but it still works though but i will change that back
was using because i thought one could change to any name

thanks for pointing that out

UPDATE:

i used this when running fabio

-e REGISTRY_CONSUL_TAGPREFIX='microservices-'

so when i run the services i used the prefix microservices-

is that a good practice?
