# OAuth2 Proxy packaged by Bitnami
|
|
|
|
A reverse proxy and static file server that provides authentication using Providers (Google, GitHub, and others) to validate accounts by email, domain or group.

|
|
|
## TL;DR
|
|
|
|
```console
|
|
$ helm repo add bitnami https://charts.bitnami.com/bitnami
|
|
$ helm install my-release bitnami/oauth2-proxy
|
|
```
|
|
|
|
## Introduction
|
|
|
|
Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.
|
|
|
|
This chart bootstraps a [OAuth2 Proxy](https://github.com/oauth2-proxy/oauth2-proxy) Deployment in a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
|
|
|
Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.
|
|
|
|
## Prerequisites
|
|
|
|
- Kubernetes 1.19+
|
|
- Helm 3.2.0+
|
|
- PV provisioner support in the underlying infrastructure
|
|
- ReadWriteMany volumes for deployment scaling
|
|
|
|
## Installing the Chart
|
|
|
|
To install the chart with the release name `my-release`:
|
|
|
|
```console
|
|
helm install my-release bitnami/oauth2-proxys
|
|
```
|
|
|
|
The command deploys OAuth2 Proxy on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) 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.
|
|
|

|
See https://github.com/bitnami-labs/readmenator to create the table
|
|
|
|
The above parameters map to the env variables defined in [bitnami/oauth2-proxy](https://github.com/bitnami/containers/tree/main/bitnami/oauth2-proxy). For more information please refer to the [bitnami/oauth2-proxy](https://github.com/bitnami/containers/tree/main/bitnami/oauth2-proxy) image documentation.
|
|
|
|
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
|
|
|
```console
|
|
helm install my-release \
|
|
--set replicaCount=2 \
|
|
bitnami/oauth2-proxy
|
|
```
|
|
|
|
The above command increase the default number of replicas.
|
|
|
|
> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
|
|
|
|
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
|
|
|
|
```console
|
|
helm install my-release -f values.yaml bitnami/oauth2-proxy
|
|
```
|
|
|
|
> **Tip**: You can use the default [values.yaml](values.yaml)
|
|
|
|
## Configuration and installation details
|
|
|
|
### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
|
|
|
|
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.
|
|
|
|
### Ingress
|
|
|
|
This chart provides support for Ingress resources. If an Ingress controller, such as nginx-ingress or traefik, that Ingress controller can be used to serve OAuth2 Proxy.
|
|
|
|
To enable Ingress integration, set `ingress.enabled` to `true`. The `ingress.hostname` property can be used to set the host name. The `ingress.tls` parameter can be used to add the TLS configuration for this host. It is also possible to have more than one host, with a separate TLS configuration for each host.
|
|
|
|
### TLS secrets
|
|
|
|
The chart also facilitates the creation of TLS secrets for use with the Ingress controller, with different options for certificate management.
|
|
|
|
## Persistence
|
|
|
|
The [Bitnami OAuth2 Proxy](https://github.com/bitnami/containers/tree/main/bitnami/oauth2-proxy) image stores the OAuth2 Proxy data and configurations at the `/bitnami` path of the container. Persistent Volume Claims are used to keep the data across deployments.
|
|
|
|
### Additional environment variables
|
|
|
|
In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.
|
|
|
|
```yaml
|
|
extraEnvVars:
|
|
- name: LOG_LEVEL
|
|
value: error
|
|
```
|
|
|
|
Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.
|
|
|
|
### Sidecars
|
|
|
|
If additional containers are needed in the same pod as OAuth2 Proxy (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter. If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter. [Learn more about configuring and using sidecar containers](https://docs.bitnami.com/kubernetes/infrastructure/oauth2-proxy/configuration/configure-sidecar-init-containers/).
|
|
|
|
### Pod affinity
|
|
|
|
This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
|
|
|
|
As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.
|
|
|
|
## Troubleshooting
|
|
|
|
Find more information about how to deal with common errors related to Bitnami's Helm charts in [this troubleshooting guide](https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues).
|
|
|
|
## Upgrading
|
|
|
|
Refer to the [chart documentation for more information about how to upgrade from previous releases](https://docs.bitnami.com/kubernetes/infrastructure/oauth2-proxy/administration/upgrade/).
