Introduction

This chart bootstraps an Rengine all stack deployment on a Kubernetes cluster using the Helm package.

1. Features

• One-step support for istio-based dual-version (baseline/upgrade) canary (grayscale) deploy, percentage traffic load supported.

• Automatically calculate the number of Pods replicas based on the traffic percentage.

• The based on istio's traffic governance capabilities, it supports the necessary functions of distributed microservices such as canary routing , request limiting, circuit breaker, fault injection, and request response filtering etc.

• Automatically add the response header x-app-version, the standard microservice interface is friendly to gray service diagnosis.

2. Prerequisites

• Kubernetes 1.21+
• Helm 3.9+
• Istio 1.12+ (Optional and recommends)

3. Getting the Chart

• helm charts global values.yaml

• From source

git clone https://github.com/wl4g/rengine.git
cd rengine/tools/deploy/helm/rengine-stack

• Or from chart repos

helm repo add rengine https://registry.wl4g.io/repository/helm-release

If you want to install an unstable version, you need to add --devel when you execute the helm install command. If you only want to test or simulate running, add the options --dry-run --debug

4. Initial deploy

• Initial deploy with baseline only

helm -n rengine upgrade -i --create-namespace rengine tools/deploy/helm/rengine-stack --set="\
apiserver.image.baselineTag=1.0.0,\
controller.image.baselineTag=1.0.0,\
executor.image.baselineTag=1.0.0

5. Upgrade deploy with canary

• 5.1 Inject istio labels for namespace

kubectl label ns rengine istio-injection=enabled --overwrite

• 5.2 Upgrade deploy with canary. (weighted by traffic)

helm -n rengine upgrade -i --create-namespace rengine tools/deploy/helm/rengine-stack --set="\
apiserver.image.baselineTag=1.0.0,\
apiserver.image.upgradeTag=1.0.1,\
controller.image.baselineTag=1.0.0,\
controller.image.upgradeTag=1.0.1,\
executor.image.baselineTag=1.0.0,\
executor.image.upgradeTag=1.0.1,\
apiserver.governance.istio.ingress.http.canary.baseline.weight=80,\
apiserver.governance.istio.ingress.http.canary.upgrade.weight=20,\
controller.governance.istio.ingress.http.canary.baseline.weight=80,\
controller.governance.istio.ingress.http.canary.upgrade.weight=20,\
executor.governance.istio.ingress.http.canary.baseline.weight=80,\
executor.governance.istio.ingress.http.canary.upgrade.weight=20"

• 5.3 After confirming that the upgrade is successful, use the new version as the benchmark, remove the old version, and switch all traffic to the new version

helm -n rengine upgrade --install --create-namespace rengine rengine-stack --set="\
apiserver.image.baselineTag=1.0.1,\
apiserver.image.upgradeTag=,\
controller.image.baselineTag=1.0.1,\
controller.image.upgradeTag=,\
executor.image.baselineTag=1.0.1,\
executor.image.upgradeTag=,\
apiserver.governance.istio.ingress.http.canary.baseline.weight=100,\
apiserver.governance.istio.ingress.http.canary.upgrade.weight=0,\
controller.governance.istio.ingress.http.canary.baseline.weight=100,\
controller.governance.istio.ingress.http.canary.upgrade.weight=0,\
executor.governance.istio.ingress.http.canary.baseline.weight=100,\
executor.governance.istio.ingress.http.canary.upgrade.weight=0"

6. Rebuild dependents

• Notice: The following dependent third-party component charts are generated based on generic templates. In fact, Rengine's required dependencies are only a subset of them, which are enabled on demand, automatic deployment of all third-party dependent components is disabled by default.

helm dependency build

helm dependency update

How to troubleshoot Pods that are missing os tools

• Use ephemeral containers to debug running or crashed Pods: kubernetes.io/docs/tasks/debug-application-cluster/debug-running-pod

• Parent charts override the property values of child charts see: github.com/whmzsu/helm-doc-zh-cn/blob/master/chart_template_guide/subcharts_and_globals-zh_cn.md
