Mimic

Creating a "live" infastructure from YAML config

Install Generator

You can download mimic-gen from Github Releases Download for MacOS on ARM

wget -c https://github.com/Ivanhahanov/mimic/releases/download/0.1.0/mimic_Darwin_arm64.tar.gz -O - | tar -xz
sudo mv ./mimic-gen /usr/local/bin/mimic-gen

Quick start

Generate k8s manifests

mimic-gen examples/infra.yml 

Apply manifests

kubectl apply -f manifests/dev -f manifests/test/

As a result we get 3 services that send http requests to each other every 10 seconds

Tip

You can explore how the services communicate using the hubble ui or hubble observe

Config Example

Create two namespace dev and test with services dev/app, dev/api and test/app.

• dev/app - port 8080, url /dev, requests to app.test and api services
• dev/api - port 8080, url /api, requests to app.test service
• test/app - port 8080, url /test, requests to app.dev service
