The Habitat operator is a Kubernetes controller designed to solve running and auto-managing Habitat Services on Kubernetes. It does this by making use of
Custom Resource Definitions.
To learn more about Habitat, please visit the Habitat website.
For a more detailed description of the Habitat type have a look here.
- Kubernetes cluster with version
- Kubectl version
go get -u github.com/habitat-sh/habitat-operator/cmd/habitat-operator
Building manually from source directory
First clone the operator:
git clone https://github.com/habitat-sh/habitat-operator.git cd habitat-operator
Then build it:
Note: Make sure the source directory is in your
$GOPATH before you execute the above command.
Running outside of a Kubernetes cluster
Start the Habitat operator by running:
habitat-operator --kubeconfig ~/.kube/config
If you built the operator manually, you'll have to specify the path to the binary. So from the root of the source directory, run:
./habitat-operator --kubeconfig ~/.kube/config
Running inside a Kubernetes cluster
Building image from source
First build the image:
This will produce a
habitat/habitat-operator image, which can then be deployed to your cluster.
The name of the generated docker image can be changed with an
IMAGE variable, for example
make image IMAGE=mycorp/my-habitat-operator. If the
habitat-operator name is fine, then a
REPO variable can be used like
make image REPO=mycorp to generate the
mycorp/habitat-operator image. Use the
TAG variable to change the tag to something else (the default value is taken from
git describe --tags --always) and a
HUB variable to avoid using the default docker hub.
Using release image
Habitat operator images are located here, they are tagged with the release version.
Deploying Habitat operator
Cluster with RBAC enabled
Make sure to give Habitat operator the correct permissions, so it's able to create and monitor certain resources. To do it, use the manifest files located under the examples directory:
kubectl create -f examples/rbac
For more information see the README file in RBAC example
Cluster with RBAC disabled
To deploy the operator inside the Kubernetes cluster use the Deployment manifest file located under the examples directory:
kubectl create -f examples/habitat-operator-deployment.yml
Deploying an example
To create an example service run:
kubectl create -f examples/standalone/habitat.yml
This will create a single-pod deployment of an
nginx Habitat service.
More examples are located in the example directory.
This project uses go dep
>= v0.4.1 for dependency management.
If you add, remove or change an import, run:
To run unit tests locally, run:
Clean up after the tests with:
Our current setup does not allow e2e tests to run locally. It is best run on a CI setup with Google Cloud.
If you change one of the types in
pkg/apis/habitat/v1beta1/types.go, run the code generation script with:
