Developer guide
Getting Started
You must have a working Go environment and then clone the repo:
git clone https://github.com/external-secrets/external-secrets.git
cd external-secrets
Note: many of the make
commands use yq, version 4.2X.X or higher.
If you want to run controller tests you also need to install kubebuilder's envtest
.
The recommended way to do so is to install setup-envtest
Here is an example on how to set it up:
go install sigs.k8s.io/controller-runtime/tools/setup-envtest@latest
# list available versions
setup-envtest list --os $(go env GOOS) --arch $(go env GOARCH)
# To use a specific version
setup-envtest use -p path 1.20.2
#To set environment variables
source <(setup-envtest use 1.20.2 -p env --os $(go env GOOS) --arch $(go env GOARCH))
for more information, please see setup-envtest docs
Building & Testing
The project uses the make
build system. It'll run code generators, tests and
static code analysis.
Building the operator binary and docker image:
make build
make docker.build IMG=external-secrets:latest
Run tests and lint the code: (golangci-lint@1.49.0 is needed.)
make test
make lint # OR
docker run --rm -v $(pwd):/app -w /app golangci/golangci-lint:v1.49.0 golangci-lint run
Build the documentation:
make docs
Installing
To install the External Secret Operator into a Kubernetes Cluster run:
helm repo add external-secrets https://charts.external-secrets.io
helm repo update
helm install external-secrets external-secrets/external-secrets
You can alternatively run the controller on your host system for development purposes:
make crds.install
make run
To remove the CRDs run:
make crds.uninstall
If you need to test some other k8s integrations and need the operator to be deployed to the actual cluster while developing, you can use the following workflow:
kind create cluster --name external-secrets
export TAG=v2
export IMAGE=eso-local
#For building in linux
docker build . -t $IMAGE:$TAG --build-arg TARGETARCH=amd64 --build-arg TARGETOS=linux
#For building in MacOS (OSX)
#docker build . -t $IMAGE:$TAG --build-arg TARGETARCH=amd64 --build-arg TARGETOS=darwin
#For building in ARM
#docker build . -t $IMAGE:$TAG --build-arg TARGETARCH=arm --build-arg TARGETOS=linux
make helm.generate
helm upgrade --install external-secrets ./deploy/charts/external-secrets/ --set image.repository=$IMAGE --set image.tag=$TAG
Contributing Flow
The HOW TO guide for contributing is at the Contributing Process page.
Documentation
We use mkdocs material and mike to generate this
documentation. See /docs
for the source code and /hack/api-docs
for the build process.
When writing documentation it is advised to run the mkdocs server with livereload:
make docs.serve
Run the following command to run a complete build. The rendered assets are available under /site
.
make docs
make docs.serve
Open http://localhost:8000
in your browser.
Since mike uses a branch to create/update documentation, any docs operation will create a diff on your local gh-pages
branch.
When finished writing/reviewing the docs, clean up your local docs branch changes with git branch -D gh-pages
