Converter

This subdirectory contains the Go command which converts topology YAML to various formats.

The root main.go outputs a Cobra CLI for controlling the behavior of the program.

Conversion Outputs

• Kubernetes (go run main.go kubernetes <topology_path> ...): Generates services and deployments for all topology services and the Fortio client to load test against them.

To generate the output for isotope mock services:

go run main.go kubernetes <topology_path> --service-image <isotope-service-image>  > output.yaml

To see all the options:

go run main.go kubernetes  --help

Using the examples

To generate the output for 2 services in a different namespace:

go run main.go kubernetes ../example-topologies/chain-2-services-different-namespaces.yaml \
    --service-image <isotope-service-image>  > output.yaml

To generate the output for specific services belonging to a given cluster name:

# For cluster1
go run main.go kubernetes ../example-topologies/chain-2-services-different-cluster.yaml \
    --service-image <isotope-service-image> --cluster cluster1  > cluster1.yaml

# For cluster2
go run main.go kubernetes ../example-topologies/chain-2-services-different-cluster.yaml \
    --service-image <isotope-service-image> --cluster cluster2  > cluster2.yaml

Using the container

docker run -it \
    -v $(pwd)/../example-topologies/chain-2-services-different-namespaces.yaml:/etc/config/service-graph.yaml  \
    <isotope-convert-image>  kubernetes --service-image <isotope-service-image>  > output.yaml

Deploy

You can build and deploy the image by your own, or to build and push the image with ko and a ephemeral registry in one command like follows:

export KO_DOCKER_REPO=ttl.sh/<my-prefix>-isotope-convert
ko build --bare -t 1h .
