OrangeHRM

OrangeHRM is a free HR management system that offers a wealth of modules to suit the needs of your business. This widely-used system is feature-rich, intuitive and provides an essential HR management platform along with free documentation and access to a broad community of users.

TL;DR;

$ helm install stable/orangehrm

Introduction

This chart bootstraps an OrangeHRM deployment on a Kubernetes cluster using the Helm package manager.

It also packages the Bitnami MariaDB chart which is required for bootstrapping a MariaDB deployment for the database requirements of the OrangeHRM application.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters. This chart has been tested to work with NGINX Ingress, cert-manager, fluentd and Prometheus on top of the BKPR.

Prerequisites

• Kubernetes 1.4+ with Beta APIs enabled
• PV provisioner support in the underlying infrastructure

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release stable/orangehrm

The command deploys OrangeHRM on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip

: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

The above parameters map to the env variables defined in bitnami/orangehrm. For more information please refer to the bitnami/orangehrm image documentation.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set orangehrmUsername=admin,orangehrmPassword=password,mariadb.mariadbRootPassword=secretpassword \
    stable/orangehrm

The above command sets the OrangeHRM administrator account username and password to admin and password respectively. Additionally, it sets the MariaDB root user password to secretpassword.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/orangehrm

Tip

: You can use the default values.yaml

Rolling VS Immutable tags

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Persistence

The Bitnami OrangeHRM image stores the OrangeHRM data and configurations at the /bitnami/orangehrm and /bitnami/apache paths of the container.

Persistent Volume Claims are used to keep the data across deployments. There is a known issue in Kubernetes Clusters with EBS in different availability zones. Ensure your cluster is configured properly to create Volumes in the same availability zone where the nodes are running. Kuberentes 1.12 solved this issue with the Volume Binding Mode.

See the Configuration section to configure the PVC or to disable persistence.

Upgrading

To 3.0.0

Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments. Use the workaround below to upgrade from versions previous to 3.0.0. The following example assumes that the release name is orangehrm:

$ kubectl patch deployment orangehrm-orangehrm --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
$ kubectl delete statefulset orangehrm-mariadb --cascade=false
