Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the commercial edition of the Bitnami catalog. + +## Introduction + +This chart bootstraps a [Memcached](https://github.com/bitnami/containers/tree/main/bitnami/memcached) 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 1.23+ +- Helm 3.8.0+ + +## Installing the Chart + +To install the chart with the release name `my-release`: + +```console +helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/memcached +``` + +> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`. + +These commands deploy Memcached 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` + +## Configuration and installation details + +### Resource requests and limits + +Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case. + +To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcePreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/). + +### [Rolling vs Immutable tags](https://docs.vmware.com/en/VMware-Tanzu-Application-Catalog/services/tutorials/GUID-understand-rolling-tags-containers-index.html) + +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 Sidecars and Init Containers + +If additional containers are needed in the same pod (such as additional metrics or logging exporters), they can be defined using the `sidecars` config parameter. + +```yaml +sidecars: +- name: your-image-name + image: your-image + imagePullPolicy: Always + ports: + - name: portname + containerPort: 1234 +``` + +If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below: + +```yaml +service: + extraPorts: + - name: extraPort + port: 11311 + targetPort: 11311 +``` + +> NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the `--enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers. + +If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example: + +```yaml +initContainers: + - name: your-image-name + image: your-image + imagePullPolicy: Always + ports: + - name: portname + containerPort: 1234 +``` + +Learn more about [sidecar containers](https://kubernetes.io/docs/concepts/workloads/pods/) and [init containers](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/). + +### Set Pod affinity + +This chart allows you to set your custom affinity using the `affinity` parameter(s). 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, you can use 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#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters. + +## Persistence + +When using `architecture: "high-availability"` the [Bitnami Memcached](https://github.com/bitnami/containers/tree/main/bitnami/memcached) image stores the cache-state at the `/cache-state` path of the container if enabled. + +Persistent Volume Claims (PVCs) are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. + +See the [Parameters](#parameters) section to configure the PVC or to disable persistence. + +If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/). + +## Parameters + +### Global parameters + +| Name | Description | Value | +| ----------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------ | +| `global.imageRegistry` | Global Docker image registry | `""` | +| `global.imagePullSecrets` | Global Docker registry secret names as an array | `[]` | +| `global.defaultStorageClass` | Global default StorageClass for Persistent Volume(s) | `""` | +| `global.storageClass` | DEPRECATED: use global.defaultStorageClass instead | `""` | +| `global.compatibility.openshift.adaptSecurityContext` | Adapt the securityContext sections of the deployment to make them compatible with Openshift restricted-v2 SCC: remove runAsUser, runAsGroup and fsGroup and let the platform use their allowed default IDs.
