Certificate Authorities
-----------------------

The above example uses a self-signed certificate. This is convenient for testing but not
representative of real-world HTTPS deployment. To get closer to that we can use `HeldCertificate`
to generate a trusted root certificate, an intermediate certificate, and a server certificate.
We use `certificateAuthority(int)` to create certificates that can sign other certificates. The

Quick Build
-------
If you want to bootstrap Maven, you'll need:
- Java 17+
- Maven 3.6.3 or later
- Run Maven, specifying a location into which the completed Maven distro should be installed:
    ```
    mvn -DdistributionTargetDir="$HOME/app/maven/apache-maven-4.0.x-SNAPSHOT" clean package
    ```

    ISTIO_CNI_ARGS="--set cni.cniBinDir=/home/kubernetes/bin"
fi
iop kube-system istio-cni $IBASE/istio-cni/ ${ISTIO_CNI_ARGS}
```

TODO. It is possible to add Istio-CNI later, and gradually migrate.

### Install Control plane

This can run in any cluster. A mesh should have at least one cluster should run Pilot or equivalent XDS server,

```
cat ${HADOOP_CONF_DIR}/core-site.xml | kv-pairify | grep "mapred"

mapred.maxthreads.generate.mapoutput=2 # Num threads to write map outputs
mapred.maxthreads.partition.closer=0 # Asynchronous map flushers
mapreduce.fileoutputcommitter.algorithm.version=2 # Use the latest committer version
mapreduce.job.reduce.slowstart.completedmaps=0.99 # 99% map, then reduce

- Secure File Transfer Protocol (SFTP) – Defined by the Internet Engineering Task Force (IETF) as an
  extended version of SSH 2.0, allowing file transfer over SSH and for use with Transport Layer
  Security (TLS) and VPN applications.

- File Transfer Protocol over SSL/TLS (FTPS) – Encrypted FTP communication via TLS certificates.

## Example Lambda handler

Install the necessary dependencies.
```sh
pip install flask requests
```

Following is an example lambda handler.
```py

Remotely Inspecting backend data

`mc support inspect` allows collecting files based on *path* from all backend drives. Matching files will be collected in a zip file with their respective host+drive+path. A MinIO host from October 2021 or later is required for full functionality. Syntax is `mc support inspect ALIAS/path/to/files`. This can for example be used to collect `xl.meta` from objects that are misbehaving. To collect `xl.meta` from a specific object, for example placed at `ALIAS/...

and aggregate telemetry data. Istio's control plane provides an abstraction
layer over the underlying cluster management platform, such as Kubernetes.

Istio is composed of these components:

- **Envoy** - Sidecar proxies per microservice to handle ingress/egress traffic

## Prerequisites

- Helm cli with Kubernetes cluster configured.
- PV provisioner support in the underlying infrastructure. (We recommend using <https://github.com/minio/direct-csi>)
- Use Kubernetes version v1.19 and later for best experience.

## Configure MinIO Helm repo

```bash
helm repo add minio https://charts.min.io/
```
