GCE Kubernetes

Mode 1 - Dependent on API Server Kubernetes deployment

  • Follow all steps at https://github.com/fossasia/open-event-orga-server/blob/nextgen/docs/installation/gce-kubernetes.md (Ensure you use the config in the nextgen branch)
  • Now switch back to this repository. (open-event-android)
  • Get another domain name for the android generator deployment. (or you can use a subdomain of another domain.)
  • Add the External IP Address One as an A record to your domain's DNS Zone.
  • Add your domain name to kubernetes/yamls/generator/ingress-notls.yml & kubernetes/yamls/generator/ingress-tls.yml. (replace droidgen.eventyay.com)
  • Run the command to start the deployment 
    ./kubernetes/deploy.sh create
  • Once deployed, your instance will be accessible at your domain name.

Mode 2 - Standalone deployment

Note: this mode is untested.

Setup

  • If you don’t already have a Google Account (Gmail or Google Apps), you must create one. Then, sign-in to Google Cloud Platform console (console.cloud.google.com) and create a new project:

  • Store your project ID into a variable as many commands below use it:

    export PROJECT_ID="your-project-id"

  • Next, enable billing in the Cloud Console in order to use Google Cloud resources and enable the Container Engine API.

  • Install Docker, and Google Cloud SDK.

  • Finally, after Google Cloud SDK installs, run the following command to install kubectl:

    gcloud components install kubectl

  • Choose a Google Cloud Project zone to run your service. We will be using us-west1-a. This is configured on the command line via:

    gcloud config set compute/zone us-west1-a

Create your Kubernetes Cluster

  • Create a cluster via the gcloud command line tool:

    gcloud container clusters create droidgen-cluster --cluster-version=1.6.4 --num-nodes=1

  • Get the credentials for kubectl to use.

    gcloud container clusters get-credentials droidgen-cluster

Deploy our pods, services and deployments

  • From the project directory, use the provided deploy script to deploy our application from the defined configuration files that are in the kubernetes directory.

    ./kubernetes/deploy.sh standalone-create

  • Get the IP address of your deployment by running. (You may need to execute it multiple times until the IP Address is assigned)

    kubectl get ingress --namespace web android-generator-notls

  • Wait for a few mins (5-10m) before you move on to the next step.

  • The generator will be accessible at the above mentioned IP address.
