Project status

The project is actively maintained and developed and has reached stable beta state. Check the complete list of releases here. The Bitpoke Stack currently runs on Google Cloud Kubernetes Engine and we also have a documented viable deployment flow for Minikube/Docker on Mac/Docker on Windows.

Installation

Add the Bitpoke helm charts repo:

helm repo add bitpoke https://helm-charts.bitpoke.io
helm repo update

Requirements

cert-manager

Cert Manager is a requirement for Stack because it depends on certificates in order to setup it's the environment. The official installation documentation can be found here.

export CERT_MANAGER_VERSION=1.6.1

helm repo add jetstack https://charts.jetstack.io
helm repo update

kubectl create namespace cert-manager
kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v${CERT_MANAGER_VERSION}/cert-manager.crds.yaml

helm install \
  cert-manager jetstack/cert-manager \
  --namespace cert-manager \
  --version v${CERT_MANAGER_VERSION}

Kubernetes Application CRD

The Stack also depends on the Kubernetes Application CRD. The following command will install the application CRD. You may also want (this is optional) to install the Application Controller, see the install guide.

kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/application/c8e2959e57a02b3877b394984a288f9178977d8b/config/crd/bases/app.k8s.io_applications.yaml

Install CRDs

For convenience we collect all necessary CRDs in one place so you can simply install them.

export STACK_VERSION=0.12.4
kubectl apply -f https://raw.githubusercontent.com/bitpoke/stack/v${STACK_VERSION}/deploy/00-crds.yaml

Install Stack

The rest of the Stack can be installed using helm 3. There are many possible platforms where it can be installed. We provide presets for production and development environments.

GKE

For GKE is required to have at least three nodes for running components and also have some room for deploying a site. For testing out and playground e1-small should suffice.

export STACK_VERSION=0.12.4
helm install \
    stack bitpoke/stack \
    --create-namespace \    
    --namespace bitpoke-stack \
    --version v${STACK_VERSION} \
    -f https://raw.githubusercontent.com/bitpoke/stack/v${STACK_VERSION}/presets/gke.yaml

Minikube/Docker for Mac

Ensure a larger Minikube with eg, minikube start --cpus 4 --memory 8192 to provide a working local environment.

export STACK_VERSION=0.12.4
helm install \
    stack bitpoke/stack \
    --create-namespace \
    --namespace bitpoke-stack \
    --version v${STACK_VERSION} \
    -f https://raw.githubusercontent.com/bitpoke/stack/v${STACK_VERSION}/presets/minikube.yaml

Usage

Deploying a site

export STACK_VERSION=0.12.4
helm install \
    mysite bitpoke/wordpress-site \
    --version v${STACK_VERSION} \
    --set 'site.domains[0]=www.example.com'
