Detailed Documentation 2. [Helm Chart](https://github.com/authelia/chartrepo) for Helm v3 see our [chart repository](https://charts.authelia.com) 3. Kustomize Deployment 4. Manifest Examples Users are welcome to reach out directly by using any of our various [contact options](../../information/contact.md). ## Important Notes The following section has special notes regarding utilizing Authelia with Kubernetes. ### External Traffic Policy Authelia (and all of your other applications) may receive an invalid remote IP if the service handling traffic to the Kubernetes Ingress of your choice doesn't have the `externalTrafficPolicy` setting configured to `local` as per the Kubernetes [preserving the client source ip] documentation. ### Enable Service Links Authelia's configuration management system conflicts with the `enableServiceLinks` option when it's set to `true` which is the default. This should be changed to `false`. See the [PodSpec v1 core](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.24/#podspec-v1-core) documentation for more details. #### Pod Example ```yaml --- apiVersion: v1 kind: Pod metadata: name: authelia spec: enableServiceLinks: false ... ``` ## FAQ ### RAM usage If using file-based authentication, the argon2id provider will by default use 1GB of RAM for password generation. This means you should allow for at least this amount in your deployment/daemonset spec and have this much available on your node, alternatively you can [tweak the providers settings](../../../configuration/first-factor/file.md#memory). Otherwise, your Authelia may OOM during login. See [here](https://github.com/authelia/authelia/issues/1234#issuecomment-663910799) for more info.
