Installation Guide
Using YAML
Voyager can be installed via installer script included in the /hack/deploy folder.
# provider=acs
# provider=aws
# provider=azure
# provider=baremetal
# provider=gce
# provider=gke
# provider=minikube
# provider=openstack
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh | bash -s -- -h
voyager.sh - install voyager operator
voyager.sh [options]
options:
-h, --help show brief help
-n, --namespace=NAMESPACE specify namespace (default: kube-system)
-p, --provider=PROVIDER specify a cloud provider
--rbac create RBAC roles and bindings (default: true)
--docker-registry docker registry used to pull voyager images (default: appscode)
--image-pull-secret name of secret used to pull voyager operator images
--restrict-to-namespace restrict voyager to its own namespace
--run-on-master run voyager operator on master
--enable-admission-webhook configure admission webhook for Voyager CRDs
--template-cfgmap=CONFIGMAP name of configmap with custom templates
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh \
| bash -s -- --provider=$provider
If you would like to run Voyager operator pod in master instances, pass the --run-on-master flag:
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh \
| bash -s -- --provider=$provider --run-on-master [--rbac]
Voyager operator will be installed in a kube-system namespace by default. If you would like to run Voyager operator pod in voyager namespace, pass the --namespace=voyager flag:
$ kubectl create namespace voyager
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh \
| bash -s -- --provider=$provider --namespace=voyager [--run-on-master] [--rbac]
By default, Voyager operator will watch Ingress objects in any namespace. If you would like to restrict Voyager to Ingress and Services in its own namespace, pass the --restrict-to-namespace flag:
$ kubectl create namespace voyager
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh \
| bash -s -- --provider=$provider --restrict-to-namespace [--namespace=voyager] [--run-on-master] [--rbac]
If you are using a private Docker registry, you need to pull the following 2 docker images:
To pass the address of your private registry and optionally a image pull secret use flags --docker-registry and --image-pull-secret respectively.
$ kubectl create namespace voyager
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh \
| bash -s -- --provider=$provider --docker-registry=MY_REGISTRY [--image-pull-secret=SECRET_NAME] [--rbac]
Voyager implements a validating admission webhook to validate Voyager CRDs. This is enabled by default for Kubernetes 1.9.0 or later releases. To disable this feature, pass the --enable-admission-webhook=false flag.
$ curl -fsSL https://raw.githubusercontent.com/appscode/voyager/6.0.0-rc.2/hack/deploy/voyager.sh \
| bash -s -- --provider=$provider --enable-admission-webhook [--rbac]
Using Helm
Voyager can be installed via Helm using the chart included in this repository or from official charts repository. To install the chart with the release name my-release:
# Mac OSX amd64:
curl -fsSL -o onessl https://github.com/kubepack/onessl/releases/download/0.1.0/onessl-darwin-amd64 \
&& chmod +x onessl \
&& sudo mv onessl /usr/local/bin/
# Linux amd64:
curl -fsSL -o onessl https://github.com/kubepack/onessl/releases/download/0.1.0/onessl-linux-amd64 \
&& chmod +x onessl \
&& sudo mv onessl /usr/local/bin/
# Linux arm64:
curl -fsSL -o onessl https://github.com/kubepack/onessl/releases/download/0.1.0/onessl-linux-arm64 \
&& chmod +x onessl \
&& sudo mv onessl /usr/local/bin/
# Kubernetes 1.8.x
$ helm repo update
$ helm install stable/voyager --name my-release --set cloudProvider=$provider
# Kubernetes 1.9.0 or later
$ helm repo update
$ helm install stable/voyager --name my-release \
--set cloudProvider=$provider \
--set apiserver.ca="$(onessl get kube-ca)" \
--set apiserver.enableAdmissionWebhook=true

Installing in GKE Cluster
If you are installing Voyager on a GKE cluster, you will need cluster admin permissions to install Voyager operator. Run the following command to grant admin permision to the cluster.
kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin --user=google-email-for-gce-project
Installing in Minikube
Voyager can be used in minikube using --provider=minikube. In Minikube, a LoadBalancer type ingress will only assigned a NodePort.
Installing in Baremetal Cluster
Voyager works great in baremetal cluster. To install, set --provider=baremetal. In baremetal cluster, LoadBalancer type ingress in not supported. You can use NodePort, HostPort or Internal ingress objects.
Verify installation
To check if Voyager operator pods have started, run the following command:
$ kubectl get pods --all-namespaces -l app=voyager --watch
Once the operator pods are running, you can cancel the above command by typing Ctrl+C.
Now, to confirm CRD groups have been registered by the operator, run the following command:
$ kubectl get crd -l app=voyager
Now, you are ready to create your first ingress using Voyager.
Configuring RBAC
Voyager creates two CRDs: Ingress and Certificate. Voyager installer will create 2 user facing cluster roles:
| ClusterRole | Aggregates To | Desription |
|---|---|---|
| appscode:voyager:edit | admin, edit | Allows edit access to Voyager CRDs, intended to be granted within a namespace using a RoleBinding. |
| appscode:voyager:view | view | Allows read-only access to Voyager CRDs, intended to be granted within a namespace using a RoleBinding. |
These user facing roles supports ClusterRole Aggregation feature in Kubernetes 1.9 or later clusters.
Using kubectl
Since Voyager uses its own TPR/CRD, you need to use full resource kind to find it with kubectl.
# List all voyager ingress
$ kubectl get ingress.voyager.appscode.com --all-namespaces
# List voyager ingress for a namespace
$ kubectl get ingress.voyager.appscode.com -n <namespace>
# Get Ingress YAML
$ kubectl get ingress.voyager.appscode.com -n <namespace> <ingress-name> -o yaml
# Describe Ingress. Very useful to debug problems.
$ kubectl describe ingress.voyager.appscode.com -n <namespace> <ingress-name>
Detect Voyager version
To detect Voyager version, exec into the operator pod and run voyager version command.
$ POD_NAMESPACE=kube-system
$ POD_NAME=$(kubectl get pods -n $POD_NAMESPACE -l app=voyager -o jsonpath={.items[0].metadata.name})
$ kubectl exec -it $POD_NAME -n $POD_NAMESPACE voyager version
