# Osclass [Osclass](https://osclass.org/) is a PHP script that allows you to quickly create and manage your own free classifieds site. Using this script, you can provide free advertising for items for sale, real estate, jobs, cars... Hundreds of free classified advertising sites are using Osclass. ## TL;DR; ```console $ helm install stable/osclass ``` ## Introduction This chart bootstraps an [Osclass](https://github.com/bitnami/bitnami-docker-osclass) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager. It also packages the [Bitnami MariaDB chart](https://github.com/kubernetes/charts/tree/master/stable/mariadb) which is required for bootstrapping a MariaDB deployment for the database requirements of the Osclass application. Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) 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](https://kubeprod.io/). ## 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`: ```console $ helm install --name my-release stable/osclass ``` The command deploys Osclass on the Kubernetes cluster in the default configuration. The [configuration](#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: ```console $ helm delete my-release ``` The command removes all the Kubernetes components associated with the chart and deletes the release. ##

For more information please refer to the [bitnami/osclass](http://github.com/bitnami/bitnami-docker-osclass) image documentation. > **Note**: > > For Osclass to function correctly, you should specify the `osclassHost` parameter to specify the FQDN (recommended) or the public IP address of the Osclass service. > > Optionally, you can specify the `osclassLoadBalancerIP` parameter to assign a reserved IP address to the Osclass service of the chart. However please note that this feature is only available on a few cloud providers (f.e. GKE). > > To reserve a public IP address on GKE: > > ```bash > $ gcloud compute addresses create osclass-public-ip > ``` > > The reserved IP address can be associated to the Osclass service by specifying it as the value of the `osclassLoadBalancerIP` parameter while installing the chart. Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example, ```console $ helm install --name my-release \ --set osclassUsername=admin,osclassPassword=password,mariadb.mariadbRootPassword=secretpassword \ stable/osclass ``` The above command sets the Osclass 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, ```console $ helm install --name my-release -f values.yaml stable/osclass ``` > **Tip**: You can use the default [values.yaml](values.yaml) ## Persistence The [Bitnami Osclass](https://github.com/bitnami/bitnami-docker-osclass) image stores the Osclass data and configurations at the `/bitnami/osclass` and `/bitnami/apache` paths of the container. Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the [Configuration](#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 osclass: ```console $ kubectl patch deployment osclass-osclass --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]' $ kubectl delete statefulset osclass-mariadb --cascade=false
