Google Kubernetes Engine

The following are steps of a sample deployment on a kubernetes cluster on Google Kubernetes Engine. All the files are present in deploy/examples/kubernetes/ directory of this repository. The following assumes the reader knows basics of kubernetes, docker & Google Cloud Platform. The steps are tested on master version-1.14.9

1. Setup External IP: Create a global static IP adress named openwisp-http-loadbalancer-ip.

2. Create a compute disk named openwisp-disk. This will be your storage disk which will store all the persistent files like user uploaded files and user database.

3. Create your cluster (Minimum 4 instances of g1-small are required for the deployment)

4. You will need "Compute Engine API - Backend services" to be atleast 7 for this deployment, please request more quota if required. (By default backend quota is 5)

5. Create GoogleCloud OpenWISP kubernetes requirements: kubectl create -f GoogleCloud.yml

6. Your system is ready, now you can move to the installation of OpenWISP on kubernetes here.

7. Setup Certificate manager for SSL certificates:

kubectl create namespace cert-manager
kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v0.12.0/cert-manager.yaml

8. In CertManager.yml: Change the email address & the domain name and create kubectl create -f CertManager.yml.

9. When the certificate is ready(check: kubectl get certificate), patch the Ingress with tls information:

kubectl patch ingress/openwisp-http-ingress \
    --patch '{
        "spec": {
            "tls": [
                {
                "hosts": [
                    "dasboard.openwisp.org",
                    "api.openwisp.org",
                    "radius.openwisp.org"
                ],
                "secretName": "openwisp-tls-secret"
                }
            ]
        }
    }'
