golang

• https://go.dev/

yq

• https://github.com/mikefarah/yq/#install

docker

• https://docs.docker.com/get-docker/

docker multi-arch support

sudo apt-get install -y qemu binfmt-support qemu-user-static

kubernetes cluster

• Install minikube https://kubernetes.io/docs/tasks/tools/install-minikube/
• Run typical minikube configuration

    minikube config set driver docker
    minikube config set cpus $(nproc)
    minikube config set kubernetes-version 1.23.1

Typical development workflow with JetBrains Goland

• open project in JetBrains Goland
• switch docker into minikube

eval $(minikube docker-env)

• run devspace

devspace dev --var=OPERATOR_NAMESPACE=kube-system --var=DEVSPACE_DEBUG=delve

• create Golang debug configuration, Run -> Edit configurations, look deploy/devspace/*.run.xml for details or use any IDE which support delve remote debugging
• update go modules if required

go mod tidy
go mod vendor

• change source files .go/.yaml etc., set breakpoints, look into .dockerignore
• devspace will rebuild docker images automatically and apply kubernetes manifest which is adopted to debug with delve.
• run Debug (SHIFT/CMD+F9)
