Kubernetes Passbolt Operator

tests

This repository contains the Kubernetes Operator for Passbolt. Passbolt is an open source password manager for teams. It is a self-hosted solution that allows you to manage your passwords securely and share them with your team. The Passbolt Operator is a Kubernetes Operator that allows you to synchronize your Passbolt credentials with Kubernetes Secrets. It is based on Kubebuilder framework.

Getting Started

Synchronize credentials with Kubernetes Secrets

The Passbolt Operator allows you to synchronize your Passbolt credentials with Kubernetes Secrets. To do so, you need to create a PassboltSecret resource. The PassboltSecret resource is a Kubernetes Custom Resource Definition (CRD) that allows you to define the Passbolt credentials that you want to synchronize with Kubernetes Secrets. The Passbolt Operator will then synchronize the Passbolt credentials with Kubernetes Secrets.

apiVersion: passbolt.tagesspiegel.de/v1alpha3
kind: PassboltSecret
metadata:
  name: passboltsecret-sample
spec:
  leaveOnDelete: false
  secretType: Opaque
  passboltSecrets:
    s3_access_key:
      name: EXAMPLE_APP
      field: username
    dsn:
      name: EXAMPLE_APP
      value: postgres://{{ .Username }}@{{ .URI }}/mydb?sslmode=disable&password={{ .Password }}
  plainTextFields:
    key: value
    foo: bar

The PassboltSecret resource contains the following fields:

Field Type Default Required Condition Description
leaveOnDelete bool false false - A boolean that indicates if the Passbolt Operator should leave the Kubernetes Secret on deletion of the PassboltSecret resource.
secretType string Opaque false - The type of the Kubernetes Secret. Can be either Opaque or kubernetes.io/dockerconfigjson. If the secretType is kubernetes.io/dockerconfigjson, the passboltSecretName field is required. If the secretType is Opaque, the secrets field is required.
passboltSecretID string - false secretType is kubernetes.io/dockerconfigjson The ID of the Passbolt credential that contains the Docker configuration (URI, Username, Password).
passboltSecrets map[string]PassboltSecrets - false secretType is Opaque A mapping of Passbolt credentials that you want to synchronize with Kubernetes Secrets. The key represents the name of the key in the Kubernetes secret to be added.
passboltSecrets[*].id string - true - The ID of the Passbolt credential that you want to synchronize with Kubernetes Secrets.
passboltSecrets[*].field string - false - The field of the Passbolt credential that you want to synchronize with Kubernetes Secrets. Can be one of: username, password, uri
passboltSecrets[*].value string - false - A Go template value of the Passbolt credential that you want to synchronize with Kubernetes Secrets. Supported variables are: Username, Password, URI. The secrets[*].passboltSecret.value field is mutually exclusive with the passboltSecrets[*].field field.
plainTextFields map[string]string - false - Assignment of plain text fields that you want to synchronize with Kubernetes Secrets. The key represents the name of the key in the Kubernetes secret to be added and the corresponding value. It is not recommended to store "secret" values such as passwords in it.

The Passbolt Operator will then synchronize the Passbolt credentials with Kubernetes Secrets. The Passbolt Operator will create a Kubernetes Secret with the name passbolt-secret-name in the namespace default. The resulting Kubernetes Secret is defined as follows:

apiVersion: v1
kind: Secret
metadata:
  name: passbolt-secret-sample
  namespace: default
type: Opaque
data:
  username: example
  pg_dsn: postgres://example@db.example.com:5432/mydb?sslmode=disable&password=example

Under the hood, the Passbolt Operator does the following during the reconciliation loop:

  1. Retrieve the Passbolt CRD from Kubernetes.
  2. Retrieve the secrets[*].passboltSecret.name credentials from Passbolt.
  3. Create a Kubernetes secret with the name passbolt-secret-name in the namespace default with the secrets[*].kubernetesSecretKey key and the secrets[*].passboltSecret.name value.

If an error occurs during the reconciliation loop, the Passbolt Operator will update the .status.syncStatus field to Error and adds the error message to the .status.syncErrors field of the PassboltSecret resource. If the reconciliation loop is successful, the Passbolt Operator will update the .status.syncStatus field of the PassboltSecret resource with the message Success.

Installation

For both installation methods, you need to create a Kubernetes Secret with the Passbolt credentials. To do so, you need to run the following command:

kubectl create secret generic controller-passbolt-secret \
  --from-file=gpg_key='/path/to/my/gpg.key' \
  --from-literal=password='<my-user-password>' \
  --from-literal=url='<my-passbolt-url>' \
  --namespace system
Prerequisites

In order to install the Passbolt Operator, you need to have the following prerequisites installed on your K8s cluster:

Kustomize

ATTENTION: This installation method is not recommended for production environments. If you want to install the Passbolt Operator in a production environment, please refer to the Helm installation method.

To install the Passbolt Operator with Kustomize, for example in a local Kind cluster, we expect that you have a working Kubernetes cluster with the controller-passbolt-secret secret created. To install the Passbolt Operator, you need to run the following commands:

  1. Load the controller-manager image into the Kind cluster. See Kind Load

make deploy
Helm

For the installation instructions regarding Helm, please refer to the Helm-Chart repository.

Configuration

The Passbolt Operator can be configured with the following environement variables:

  • PASSBOLT_URL: The URL of the Passbolt instance.
  • PASSBOLT_GPG: The GPG key to identify the user.
  • PASSBOLT_PASSWORD: The password of the Passbolt user.

Development

Prerequisites
Setup the development environment

To setup the development environment, you need to run the following commands:

docker-compose up -d

Restore the database

mysql \
  --host=127.0.0.1 \
  --port=13306 \
  --database=passbolt \
  --user=passbolt \
  --password=P4ssb0lt < _data/passbolt_db.sql
Create another API (Version)

Kubebuilder allows you to bootstrap a new API Version. To do so, you need to run the following command:

kubebuilder create api --group passbolt --version v1alpha1 --kind PassboltSecret
Create validation and defaulting webhooks

Kubebuilder allows you to bootstrap a new webhook. To do so, you need to run the following command:

kubebuilder create webhook --group passbolt --version v1alpha1 --kind PassboltSecret --defaulting --programmatic-validation
Start the Operator

Since the Operator requires a running instance of Passbolt, we will use the Passbolt Docker image to start a Passbolt instance. To start the Passbolt instance, you need to run the following command:

docker-compose up -d

When the Passbolt instance is up and running, the second step would be to expose the Passbolt instance credentials to the Operator. To do so, you need to run the following command:

./_data/credentials.sh

The last step would be to start the Operator. To do so, you need to run the following command:

make run
Create a User in Passbolt

To create a user in Passbolt, you need to run the following command:

docker exec -ti passbolt /usr/share/php/passbolt/bin/cake \
  passbolt register_user \
  -u user.example@mydomain.local \
  -f user \
  -l example \
  -r admin

We already created a user with the above command. You can retrieve the password and the GPG key from the _data/credentials.sh file.

Test the Operator

In order to run the end-to-end and unit tests, we need to start passbolt locally. To do so, you need to run the following command:

docker-compose up -d

When the Passbolt instance is up and running, the second step would be to execute the end-to-end and unit tests. To do so, you need to run the following command:

make test

Note:

When we bootstraped passbolt, we created two secrets:

ID Name
184734ea-8be3-4f5a-ba6c-5f4b3c0603e8 APP_EXAMPLE
cec328ec-cb1f-48f6-be1e-1ca35fc3c62d APP2_EXAMPLE
In Cluster Testing (Kind)

In order to run the end-to-end tests in a Kubernetes cluster, we need to load the Passbolt Operator image into the Kind cluster. To do so, you need to run the following command:

kind load docker-image <image-name> --name <cluster-name> --nodes <node-names-separated-by-a-comma>

When the Passbolt Operator image is loaded into the Kind cluster, the second step would be to deploy the Passbolt Operator in the Kind cluster. To do so, you need to run the following command:

IMG="my-img-name:latest" make deploy
Continuous Integration (CI)

During the continuous integration, we automatically run the end-to-end and unit tests. To do so, we use the GitHub Actions platform. The GitHub Actions configuration is defined in the .github/workflows directory.

During the end-to-end and unit tests, we restore the the mysql Passbolt database from the _data/passbolt_db.sql file. The '_data/passbolt_db.sql' file was generated with the following command:

mysqldump \
  --host=127.0.0.1 \
  --port=13306 \
  --databases passbolt \
  --user=passbolt \
  --password=P4ssb0lt > _data/passbolt_db.sql
