Installation of Epinio


Epinio is installed from a single Helm chart and, by default, it also installs Kubed, MinIO and a container registry in your Kubernetes cluster.

You can disable the installation of Kubed, 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.


Ingress Controller

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 "" \
--set globalArguments='' \
--set-string ports.web.redirectTo=websecure \
--set-string ingressClass.enabled=true \
--set-string ingressClass.isDefaultClass=true \
--set-string service.spec.loadBalancerIP=$LOAD_BALANCER_IP

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 size by adding an annotation to your ingress as described in

Cert Manager

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
$ helm repo update
$ helm install cert-manager --namespace cert-manager jetstack/cert-manager \
--set installCRDs=true \
--set extraArgs={--enable-certificate-owner-ref=true}

WARNING: if cert-manager isn't installed in the namespace cert-manager, you have to set .Values.certManagerNamespace accordingly, 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".

S3 storage

Epinio is using an S3 compatible storage to store the application source code. This chart will install Minio when .Values.minio.enabled is true (default). Any S3 compatible solution can be used instead by setting this value to false and using the values under s3 to point to the desired S3 server.

Container Registry

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 .Values.containerregistry.enabled is true (default).

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.

Install Epinio

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
$ helm install epinio -n epinio --create-namespace epinio/epinio --values epinio-values.yaml --set

The only value that is mandatory is the which should be a wildcard domain, pointing to the IP address of your running Ingress controller.

NOTE: If you're deploying Epinio in a "localhost" environment, you can use a "magic domain name".

NOTE II: in case the installation fails due to an expired certificate (for instance if you have previously initialized the epinio cli on a machine for a different cluster) please consider executing epinio epinio settings update-ca. More info at: epinio-settings-update-ca

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:

NOTE: The Public Cloud howto lists the three major Cloud providers but Epinio can run on any Kubernetes cluster.
