Copilot
To help Istio Pilot work with Cloud Foundry
You probably want to deploy this using Istio Release.
Development
To get started:
git clone https://github.com/cloudfoundry/copilot.git
cd copilot
go get github.com/onsi/ginkgo/ginkgo
go get github.com/golang/dep/cmd/dep
dep ensure
To run the tests:
ginkgo -r -p -race
To compile the server:
go build code.cloudfoundry.org/copilot/cmd/copilot-server
Using the Server
We are using a generic grpc client to interact with cloud controller grpc service (installation instructions below)
Setup GRPC Client
If you are developing locally, you can install grpcurl
go get -u github.com/fullstorydev/grpcurl
If you are using a cloudfoundry
- bosh ssh to the istio-control vm and
sudo su
- grpcurl is at
/var/vcap/packages/grpcurl/bin/grpcurl
- the certs you need are in
/var/vcap/jobs/pilot-discovery/config/certs/
Push an App
cf push ...
Find Diego Process GUID
Get the CAPI Process GUID:
The following example assumes the "web" process type, but you can replace that with another type if you know what you're doing.
export CAPI_PROCESS_GUID=$(cf curl "/v3/apps/$(cf curl "/v3/apps" | jq -r '.resources[] | select(.name == "<app-name>") | .guid')/processes" | jq -r '.resources[] | select(.type == "web") | .guid')
Get the CAPI Process Version:
The CAPI Process GUID is not sufficient for routing. If you want to map/delete a route, you'll need the entire <capi-process-guid>-<version>
concatenation (the "Diego Process GUID"):
export APP_GUID=$(cf app <my-app> --guid) # to obtain the application guid export CAPI_PROCESS_VERSION=$(cf curl /v2/apps/$APP_GUID | jq -r .entity.version) # to obtain the version
Construct the Diego Process GUID
export DIEGO_PROCESS_GUID="$CAPI_PROCESS_GUID-$CAPI_PROCESS_VERSION"
Get the Route Guid used by Cloud Controller
Given an existing route in cloud controller...
export CAPI_ROUTE_GUID=$(cf curl /v2/routes | jq -r '.resources[] | select(.entity.host == "<hostname-of-existing-route>").metadata.guid')
