Example Service

Example Micro Service with GO

Pre-Req

• Go 1.3+
• Docker
• Direnv
• Editor ( ex: VS Code)

To Install the pre-reqs, which is usually a one time setup of your dev env

brew install go direnv
brew cask install visual-studio-code

Build

to build the source

make clean build

NOTE: This will download all the required tool dependencies for the first time and add them to your <PROJECT_ROOT>/.tools folder. You can run make install-deptools to only install dependent tools. See Makefile for additional targets

Local kubernetes dev cluster

to bring up a local kubernetes dev cluser with postgres

make cluster-local

NOTE: In order for the above command to work please make sure docker is installed. The resulting cluster is based on Kubernetes IN Docker (aka kind)

If already have run make clean build then the tools folder would have kubectl which you could use to talk to the kubernetes cluster.

To use the local cluster you need to set the KUBECONFIG

export KUBECONFIG=$(kind get kubeconfig-path --name cnative-local)

kubectl get pods -A

or you can create an alias like

alias lk='kubectl --kubeconfig=$(kind get kubeconfig-path --name cnative-local)'

lk get pods -A

to clean up the local cluster

make cluster-local-delete
