Description
Issue Type:
- Bug report
- Feature request
We are running a Linkerd-to-Linkerd setup where we use http_proxy to route HTTP traffic to Linkerd, but in our infrastructure internet access is only provided using a proxy server. We need to be able to tell Linkerd to proxy internet traffic to another proxy server.
Here is the Linkerd config we use today:
admin:
ip: 0.0.0.0
port: 9990
namers:
- kind: io.l5d.consul
includeTag: true
failFast: true
useHealthCheck: false
host: infrastructure-consul
port: 8500
routers:
- label: http1-out
protocol: http
servers:
- port: 4140
ip: 0.0.0.0
dtab: |
/svc => /#/io.l5d.consul/.local/external;
/host => /svc;
/http/*/* => /host;
identifier:
kind: io.l5d.header.token
- label: http1-in
protocol: http
servers:
- port: 4141
ip: 0.0.0.0
dtab: |
/svc => /#/io.l5d.consul/.local/internal;
/host => /svc;
/http/*/* => /host;
identifier:
kind: io.l5d.header.token
telemetry:
- kind: io.zipkin.http
host: zipkin:9411
initialSampleRate: 1.00

orgId: linkerd-examples-consul
We have tried to use the io.buoyant.rinet but that only gives us the feature to make Linkerd make http requests to external resources, but not to a proxy. We could route internet traffic directly to the Internet proxy, but then we loos all the features of Linkerd and we need to implement that in all our services.
We are only using http(s) so we do only need to talk to an http proxy(in our case a squid).
Our end gold would be a flow looking like this:
[service] -> [Linkerd] -> [InternetProxy] -> (Internet)
Or if multiple connected services are in play:
[service] -> [Linkerd] -> [Linkerd] -> [service] -> [Linkerd] -> [InternetProxy] -> (Internet)
Environment:
- Linkerd version 1.3.5
