<!--- app-name: NGINX Open Source -->
# NGINX Open Source packaged by Bitnami
NGINX Open Source is a web server that can be also used as a reverse proxy, load balancer, and HTTP cache. Recommended for high-demanding sites due to its ability to provide faster content.
[Overview of NGINX Open Source](http://nginx.org)
Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.
## TL;DR
```console
helm repo add my-repo https://charts.bitnami.com/bitnami
helm install my-release my-repo/nginx
```
## 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 [NGINX Open Source](https://github.com/bitnami/containers/tree/main/bitnami/nginx) deployment on 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+
## Installing the Chart
To install the chart with the release name `my-release`:
```console
helm repo add my-repo https://charts.bitnami.com/bitnami
helm install my-release my-repo/nginx
```
These commands deploy NGINX Open Source on the Kubernetes cluster in the default configuration.
> **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.

## 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.
### Use a different NGINX version
To modify the application version used in this chart, specify a different version of the image using the `image.tag` parameter and/or a different repository using the `image.repository` parameter. Refer to the [chart documentation for more information on these parameters and how to use them with images from a private registry](https://docs.bitnami.com/kubernetes/infrastructure/nginx/configuration/change-image-version/).
### Deploying your custom web application
The NGINX chart allows you to deploy a custom web application using one of the following methods:
- Cloning from a git repository: Set `cloneStaticSiteFromGit.enabled` to `true` and set the repository and branch using the `cloneStaticSiteFromGit.repository` and `cloneStaticSiteFromGit.branch` parameters. A sidecar will also pull the latest changes in an interval set by `cloneStaticSitesFromGit.interval`.
- Providing a ConfigMap: Set the `staticSiteConfigmap` value to mount a ConfigMap in the NGINX html folder.
- Using an existing PVC: Set the `staticSitePVC` value to mount an PersistentVolumeClaim with the static site content.
You can deploy a example web application using git deploying the chart with the following parameters:
```console
cloneStaticSiteFromGit.enabled=true
cloneStaticSiteFromGit.repository=https://github.com/mdn/beginner-html-site-styled.git
cloneStaticSiteFromGit.branch=master
```
### Providing a custom server block
This helm chart supports using custom custom server block for NGINX to use.
You can use the `serverBlock` value to provide a custom server block for NGINX to use. To do this, create a values files with your server block and install the chart using it:
```yaml
serverBlock: |-
server {
listen 0.0.0.0:8080;
location / {
return 200 "hello!";
}
}
```
> Warning: The above example is not compatible with enabling Prometheus metrics since it affects the `/status` endpoint.
In addition, you can also set an external ConfigMap with the configuration file. This is done by setting the `existingServerBlockConfigmap` parameter. Note that this will override the previous option.
### Adding extra 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.
### Setting Pod's affinity
This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinity) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.
### Deploying extra resources
There are cases where you may want to deploy extra objects, such a ConfigMap containing your app's configuration or some extra deployment with a micro service used by your app. For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter.
### Ingress
This chart provides support for ingress resources. If you have an ingress controller installed on your cluster, such as [nginx-ingress-controller](https://github.com/bitnami/charts/tree/main/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/main/bitnami/contour) you can utilize the ingress controller to serve your application.
To enable ingress integration, please set `ingress.enabled` to `true`.
#### Hosts
Most likely you will only want to have one hostname that maps to this NGINX installation. If that's your case, the property `ingress.hostname` will set it. However, it is possible to have more than one host. To facilitate this, the `ingress.extraHosts` object can be specified as an array. You can also use `ingress.extraTLS` to add the TLS configuration for extra hosts.
For each host indicated at `ingress.extraHosts`, please indicate a `name`, `path`, and any `annotations` that you may want the ingress controller to know about.
For annotations, please see [this document](https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/annotations.md). Not all annotations are supported by all ingress controllers, but this document does a good job of indicating which annotation is supported by many popular ingress controllers.

## Upgrading
### To 11.0.0
This major release renames several values in this chart and adds missing features, in order to be aligned with the rest of the assets in the Bitnami charts repository.
Affected values:
- `service.port` was renamed as `service.ports.http`.
- `service.httpsPort` was deprecated. We recommend using `service.ports.https`.
- `serviceAccount.autoMount` was renamed as `serviceAccount.automountServiceAccountToken`
- `metrics.serviceMonitor.additionalLabels` was renamed as `metrics.serviceMonitor.labels`
### To 10.0.0
This major release no longer uses the bitnami/nginx-ldap-auth-daemon container as a dependency since its upstream project is not actively maintained.
*2022-04-12 edit*:
[Bitnami's reference implementation](https://www.nginx.com/blog/nginx-plus-authenticate-users/).
On 9 April 2022, security vulnerabilities in the [NGINX LDAP reference implementation](https://github.com/nginxinc/nginx-ldap-auth) were publicly shared. **Although the deprecation of this container from the Bitnami catalog was not related to this security issue, [here](https://docs.bitnami.com/general/security/) you can find more information from the Bitnami security team.**
### To 8.0.0
[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
#### What changes were introduced in this major version?
- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
- After running `helm dependency update`, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
#### Considerations when upgrading to this version
- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3

- <https://helm.sh/docs/topics/v2_v3_migration/>
- <https://helm.sh/blog/migrate-from-helm-v2-to-helm-v3/>
### To 7.0.0
- This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/main/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
- Ingress configuration was also adapted to follow the Helm charts best practices.
> Note: There is no backwards compatibility due to the above mentioned changes. It's necessary to install a new release of the chart, and migrate your existing application to the new NGINX instances.
### To 5.6.0
Added support for the use of LDAP.
