Installation of Epinio
You can disable the installation of
MinIO and the
container registry by changing the settings as described in the respective sections.
See system requirements for a detailed list of external components your Kubernetes cluster needs to have before you install Epinio.
IMPORTANT: Some of the namespaces of the components are hardcoded in the Epinio code and thus are important to be the same as described here. In the future this may be configurable on the Epinio Helm chart.
Epinio creates Ingress resources for the API server, the applications and depending on your setup, the internal container registry. Those resources won't work unless an Ingress controller is running on your cluster.
If you don't have an Ingress controller already running, you can install Traefik with:
$ kubectl create namespace traefik
$ export LOAD_BALANCER_IP=$(LOAD_BALANCER_IP:-) # Set this to the IP of your load balancer if you know that
$ helm install traefik --namespace traefik "https://helm.traefik.io/traefik/traefik-10.3.4.tgz" \
--set globalArguments='' \
--set-string ports.web.redirectTo=websecure \
--set-string ingressClass.enabled=true \
--set-string ingressClass.isDefaultClass=true \
It's also possible to use Nginx instead of Traefik following the official documentation.
Do not forget to use the option
--set controller.setAsDefaultIngress=true when you install Nginx.
Otherwise, if you do not want defining Nginx as the default ingress, feel free to use
--set ingress.ingressClassName=nginxwhen you deploy Epinio.
WARNING: Sometimes, when Epinio uploads your app, you might see
error pushing app to server: can't upload archive: server status code: Request Entity Too Large.
In this case, you need to increase the
max body sizeby adding an annotation to your ingress as described in nginx.ingress.kubernetes.io/proxy-body-size
Epinio needs cert-manager in order to create TLS certificates for the various Ingresses (see "Ingress controller" above).
If cert-manager is not already installed on the cluster, it can be installed like this:
$ kubectl create namespace cert-manager
$ helm repo add jetstack https://charts.jetstack.io
$ helm repo update
$ helm install cert-manager --namespace cert-manager jetstack/cert-manager \
--set installCRDs=true \
WARNING: if cert-manager isn't installed in the namespace
cert-manager, you have to set
.Values.certManagerNamespaceaccordingly, otherwise Epinio installation will fail.
Kubed is installed as a subchart when
.Values.kubed.enabled is true (default).
If you already have kubed running, you can skip the installation by setting
the helm value "kubed.enabled" to "false".
Epinio is using an S3 compatible storage to store the application source code.
This chart will install Minio when
true (default). Any S3 compatible solution can be used instead by setting this
false and using the values under
to point to the desired S3 server.
When Epinio builds a container image for an application from source, it needs
to store that image to a container registry. Epinio installs a container registry
on the cluster when
Any container registry that supports basic auth authentication (e.g. gcr, dockerhub etc) can be used
instead, by setting this value to
false and using
the relevant global values
to point to the desired container registry.
If the above dependencies are available or going to be installed by this chart, Epinio can be installed with the following:
$ helm repo add epinio https://epinio.github.io/helm-charts
$ helm install epinio -n epinio --create-namespace epinio/epinio --values epinio-values.yaml --set global.domain=myepiniodomain.org
The only value that is mandatory is the
should be a wildcard domain, pointing to the IP address of your running

NOTE: If you're deploying Epinio in a "localhost" environment, you can use a "magic domain name".
Installation on Specific Kubernetes Offerings
Installing Epinio is a standard process as explained above, however you might need to configure it for a specific Kubernetes cluster.
To help you, see the following HowTos for various well-known Kubernetes clusters:
- Install on Rancher - Install Epinio on Rancher
- Install on Public Cloud - Install Epinio on Public Cloud cluster
- Install on RKE2 - Install Epinio on Rancher RKE2 cluster
- Install on K3d - Install Epinio on K3d cluster
- Install on K3s - Install Epinio on K3s cluster
- Install on Rancher Desktop - Install Epinio on Rancher Desktop
- Install on Minikube - Install Epinio on Minikube cluster
NOTE: The Public Cloud howto lists the three major Cloud providers but Epinio can run on any Kubernetes cluster.
