[GitHub] [apisix] yangxikun opened a new issue #2536: request help: In istio mesh, apisix proxy request to upstream cann't use istio traffic control

yangxikun opened a new issue #2536:
URL: https://github.com/apache/apisix/issues/2536


   ### Issue description
   
   We deploy apisix in istio mesh, and configure apisix route request to upstream(an k8s service).
   
   The client request example:
   
   ```
   GET /a/b/c HTTP/1.1
   Host: foo.com
   ```
   
   The upstream: http://foo.default.svc:8080.
   
   The `Host: foo.com` will be proxy to foo service backend, but the istio sidecar cann't route these request.
   
   So we modified apisix/init.lua:
   
   ```
   function _M.http_access_phase()
   
       ......
   
       set_upstream_host(api_ctx)
   
       ngx.var.upstream_host = api_ctx.upstream_conf.nodes[1].domain
   end
   ```
   
   Change $upstream_host to configured upstream domain, so that the proxy request host will be foo.default.svc, then istio sidecar can route correctly.
   
   Is there a more elegant way to solve this problem?
   
   ### Environment
   
   * apisix version (cmd: `apisix version`): 1.5
   * OS:

   Found a solution: set upstream admin api parameter pass_host=node.
