Manual overrides: requesting extra information in documentation #364

I am trying to figure out how to configure manual route overrides. As far as I can understand, those have to be added to consul kv in /fabio/config ?

I am not sure how to add those? I tried querying consul i.e. consul kv get ./fabio/config consul kv get fabio/config consul kv get /fabio/config And none works. An example on how to add those would be very helpful. I am not sure if I am supposed to do something like: consul kv put /fabio/config .... ?

You can go to http://localhost:9998/manual and set them there or use consul kv put fabio/config '#foo' for example. Please note that you can change the prefix in fabio.properties with registry.consul.kvpath

Just to add to this. We are updating the weighting of our microservices via consul.

we retrive the current value of fabio/config and then append to it using consul kv put fabio/config '#foo'.

My question is what is the best way to maintain the routing that has been added to the kv?

e.g. I update the weighting rules for service-a I update the weighting rules for service-b

service-a is no longer required and is removed from the environment. How would I tidy up the rules by removing service-a in fabio/config without affecting service-b? I didn't want to do this manually. I wanted it so that if service-a is un-deployed from an environment via a scripts, it would also tidy up the routing for that service too.

Is it possible that you could have fabio/config/service-a and fabio/config/service-b? so services are maintained separately? so when a microservice is terminated I can remove the kv entry just for that service
