Steerer is a Kubernetes operator that automates the promotion of canary deployments
Flagger is a Kubernetes operator that automates the promotion of canary deployments
using Istio routing for traffic shifting and Prometheus metrics for canary analysis.
The project is currently in experimental phase and it is expected that breaking changes
to the API will be made in the upcoming releases.
### Install
Before installing Steerer make sure you have Istio setup up with Prometheus enabled.
Before installing Flagger make sure you have Istio setup up with Prometheus enabled.
If you are new to Istio you can follow my [Istio service mesh walk-through](https://github.com/stefanprodan/istio-gke).
Deploy Steerer in the `istio-system` namespace using Helm:
Deploy Flagger in the `istio-system` namespace using Helm:
```bash
# add the Helm repository
helm repo add steerer https://stefanprodan.github.io/steerer
helm repo add flagger https://stefanprodan.github.io/flagger
# install or upgrade
helm upgrade -i steerer steerer/steerer \
helm upgrade -i flagger flagger/flagger \
--namespace=istio-system \
--set metricsServer=http://prometheus.istio-system:9090 \
--set controlLoopInterval=1m
```
Steerer is compatible with Kubernetes >1.10.0 and Istio >1.0.0.
Flagger is compatible with Kubernetes >1.10.0 and Istio >1.0.0.
### Usage
Steerer requires two Kubernetes [deployments](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/):
Flagger requires two Kubernetes [deployments](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/):
one for the version you want to upgrade called _primary_ and one for the _canary_.
Each deployment must have a corresponding ClusterIP [service](https://kubernetes.io/docs/concepts/services-networking/service/)
that exposes a port named http or https. These services are used as destinations in a Istio [virtual service](https://istio.io/docs/reference/config/istio.networking.v1alpha3/#VirtualService).

Steerer is a Kubernetes operator that automates the promotion of canary deployments
Flagger is a Kubernetes operator that automates the promotion of canary deployments
using Istio routing for traffic shifting and Prometheus metrics for canary analysis.
The project is currently in experimental phase and it is expected that breaking changes
to the API will be made in the upcoming releases.
### Install
Before installing Steerer make sure you have Istio setup up with Prometheus enabled.
Before installing Flagger make sure you have Istio setup up with Prometheus enabled.
If you are new to Istio you can follow my [Istio service mesh walk-through](https://github.com/stefanprodan/istio-gke).
Deploy Steerer in the `istio-system` namespace using Helm:
Deploy Flagger in the `istio-system` namespace using Helm:
```bash
# add the Helm repository
helm repo add steerer https://stefanprodan.github.io/steerer
helm repo add flagger https://stefanprodan.github.io/flagger
# install or upgrade
helm upgrade -i steerer steerer/steerer \
helm upgrade -i flagger flagger/flagger \
--namespace=istio-system \
--set metricsServer=http://prometheus.istio-system:9090 \
--set controlLoopInterval=1m
```
Steerer is compatible with Kubernetes >1.10.0 and Istio >1.0.0.
Flagger is compatible with Kubernetes >1.10.0 and Istio >1.0.0.
### Usage
Steerer requires two Kubernetes [deployments](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/):
Flagger requires two Kubernetes [deployments](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/):
one for the version you want to upgrade called _primary_ and one for the _canary_.
Each deployment must have a corresponding ClusterIP [service](https://kubernetes.io/docs/concepts/services-networking/service/)
that exposes a port named http or https. These services are used as destinations in a Istio [virtual service](https://istio.io/docs/reference/config/istio.networking.v1alpha3/#VirtualService).

Steerer comes with a Grafana dashboard made for canary analysis.
Flagger comes with a Grafana dashboard made for canary analysis.
Install Grafana with Helm:

helm upgrade -i flagger-grafana flagger/grafana \
--namespace=istio-system \
--set url=http://prometheus.istio-system:9090
