The Kubernetes-native Service Broker.
Google Container Engine (GKE) is a managed Kubernetes environment which is great for hosting Drycc Workflow. Google Container Engine manages the Kubernetes master and you pay for the compute nodes. Clusters smaller than five nodes are charged only for the compute. Clusters six nodes are larger cost $0.15/hour per cluster.
If you do not already have a Google Cloud account, you can start a trial with $300 of free credit here. After completing sign up, you must add your billing information.
Sign in to your Google Cloud Platform Console and create a new project:
Pick a project name. A project groups resources together and can hold more than one container cluster:
Note the project ID. This is a unique name across all Google Cloud projects. Later, we will refer to this as
From the navigation hamburger in the upper left corner, find and select Container Engine:
Select Create Container Cluster:
For development and testing, we recommend you use the
n1-standard-2 machine type which has 2 VCPUs and 7.5 GB of RAM per server, and a cluster size of at least 2:
Click "Create" and Google Container Engine will provision your cluster. The process will take a few minutes to complete.
After the cluster is created, check the node version. See Kubernetes Versions under System Requirements for more details.
While your container cluster is booting. You will need to install the Google Cloud CLI tools. We will use the tools to fetch cluster credentials to authenitcate to your new Kubernetes cluster.
Google maintains a number of quickstart guides which walk you through the installation.
Once you have installed the CLI tooling set your default project and list your container clusters:
$ gcloud projects list PROJECT_ID NAME PROJECT_NUMBER ascendant-yeti-130419 My First Cluster 614974141267
Set your default project:
$ gcloud config set project ascendant-yeti-130419
Then list your container clusters:
$ gcloud container clusters list NAME ZONE MASTER_VERSION MASTER_IP MACHINE_TYPE NODE_VERSION NUM_NODES STATUS cluster-1 us-central1-b 1.4.0 22.214.171.124 n1-standard-2 1.4.0 * 2 RUNNING
If you haven't configured your default zone, make sure it matches the ZONE for your cluster:
$ gcloud config set compute/zone us-central1-b
Now you may fetch credentials to connect to Kubernetes:
$ gcloud auth application-default login Your browser has been opened to visit: https://accounts.google.com/o/oauth2/auth?redirect_uri=.... Credentials saved to file: [~/.config/gcloud/application_default_credentials.json] These credentials will be used by any library that requests Application Default Credentials.
If you don't have
kubectl CLI setup just yet, run this to get it available
$ gcloud components install kubectl
kubectl utility should now be pointed at your new container cluster. You can verify your credentials and local configuration by running:
$ kubectl cluster-info Kubernetes master is running at https://126.96.36.199 GLBCDefaultBackend is running at https://188.8.131.52/api/v1/proxy/namespaces/kube-system/services/default-http-backend Heapster is running at https://184.108.40.206/api/v1/proxy/namespaces/kube-system/services/heapster KubeDNS is running at https://220.127.116.11/api/v1/proxy/namespaces/kube-system/services/kube-dns kubernetes-dashboard is running at https://18.104.22.168/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard
kubectl cluster-info returned with the following error:
The connection to the server localhost:8080 was refused - did you specify the right host or port?
You'll need to run:
$ gcloud container clusters get-credentials
To download the credentials necessary. The
kubectl cluster-info command should then work as intended.
You are now ready to install Drycc Workflow
