# Install Bundle Plugins from a Private Image Repository

# Overview

The standard deployment of the Entando Component Repository assumes that plugin images are pulled from public repositories. Public repositores do not require user authentication in order to pull an image. The following tutorial will show you how to add secrets to your Kubernetes environment so you can successfully pull images from private repositories.

# Prerequisites

  • A running Entando application
  • A bundle containing a microservice plugin based on an image from a private repository. You can set this up by creating a microservice bundle and making the corresponding Docker Hub repository private.

# Tutorial

The first step demonstrates how to create a Secret for Docker Hub but please see the corresponding Kubernetes documentation (opens new window) for other options.

1. Create the secret Supply the following parameters:

  • the name of the new Secret, e.g. my-docker-secret.
  • the URL to your registry server. For Docker Hub this is currently https://index.docker.io/v1/ (opens new window)
  • your Docker Hub username, password, and email.
  • the Entando namespace, e.g. entando for a quickstart environment.
kubectl create secret docker-registry YOUR-SECRET-NAME --docker-server=YOUR-REGISTRY-SERVER --docker-username=YOUR-USERNAME --docker-password=YOUR-PASSWORD --docker-email=YOUR-EMAIL -n entando

2a. Deploy a new Entando Application

If you're setting up a new Entando Application, you can add the secret to the Entando Operator ConfigMap under the property entando.k8s.operator.image.pull.secrets. This is just a list containing the names of Docker Secrets in the operator's namespace.

  entando.k8s.operator.image.pull.secrets: [YOUR-SECRET-NAME]

2b. Update an existing Entando Application

If you're updating an existing Entando Application, you can add the new Secret to the entando-plugin serviceaccount.

kubectl edit serviceaccount entando-plugin -n entando

Add the secret to the serviceaccount. You can either add a new section if it's the first Secret or add another Secret to the list.

apiVersion: v1
kind: ServiceAccount
  name: entando-plugin

If you describe the serviceaccount, it should list the Secret.

kubectl describe serviceaccount entando-plugin -n entando


Name:                entando-plugin
Namespace:           entando
Image pull secrets:  YOUR-SECRET-NAME

If (not found) is listed next to the Secret name, then you may have added the Secret to the wrong namespace.

3. Install the Entando Bundle

You can now install Entando Bundles from the Entando App BuilderEntando Component Repository. The microservice plugin should now be able to successfully pull the image.

# Troubleshooting

You may see an ErrImagePull status in kubectl get pods if a plugin is based on an image from a private repository and if there are any issues with the image URL or credentials, including a missing or incorrect Secret.
