new files. **Do not add RELNOTE=yes comments in CLs.** Instead, add a file to
the CL (or ask the author to do so).

At the end of the development cycle, the files will be merged by being
concatenated in sorted order by pathname. Files in the directory matching the
glob "*stdlib/*minor" are treated specially. They should be in subdirectories

If you are able to, a clean installation is simpler. However, this often requires an external IP migration which can be challenging.

WARNING: when installing over an existing deployment, the two deployments will be merged together by Helm, which may lead to unexpected results.

#### Legacy Gateway Helm charts

Istio historically offered two different charts - `manifests/charts/gateways/istio-ingress` and `manifests/charts/gateways/istio-egress`.

# MinIO Monitoring Guide

MinIO server exposes monitoring data over endpoints. Monitoring tools can pick the data from these endpoints. This document lists the monitoring endpoints and relevant documentation.

## Healthcheck Probe

MinIO server has two healthcheck related un-authenticated endpoints, a liveness probe to indicate if server is responding, cluster probe to check if server can be taken down for maintenance.

export MINIO_ROOT_USER=minio

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,
and it is recommended to have Pilot running in each region and in multiple availability zones for multi cluster.

```bash
iop istio-control istio-discovery $IBASE/istio-control/istio-discovery \

  // instance for every unit test.
  MockWebServer server = new MockWebServer();

  // Schedule some responses.
  server.enqueue(new MockResponse().setBody("hello, world!"));
  server.enqueue(new MockResponse().setBody("sup, bra?"));
  server.enqueue(new MockResponse().setBody("yo dog"));

  // Start the server.
  server.start();

  // Ask the server for its URL. You'll need this to make HTTP requests.

To host multiple tenants on a single machine, run one MinIO Server per tenant with a dedicated HTTPS port, configuration, and data directory.

### 1.1 Host Multiple Tenants on a Single Drive

Use the following commands to host 3 tenants on a single drive:

```sh
minio server --address :9001 /data/tenant1
minio server --address :9002 /data/tenant2
minio server --address :9003 /data/tenant3
```

```

### TLS (FTP)

Unlike SFTP server, FTP server is insecure by default. To operate under TLS mode, you need to provide certificates via

```
--ftp="tls-private-key=path/to/private.key" --ftp="tls-public-cert=path/to/public.crt"
```

> NOTE: if MinIO distributed setup is already configured to run under TLS, FTP will automatically use the relevant

Install MinIO - [MinIO Quickstart Guide](https://min.io/docs/minio/linux/index.html#quickstart-for-linux)

### 2. Run MinIO Server with Erasure Code

Example: Start MinIO server in a 12 drives setup, using MinIO binary.

```sh
minio server /data{1...12}
```

Example: Start MinIO server in a 8 drives setup, using MinIO Docker image.

```sh
podman run \
  -p 9000:9000 \
  -p 9001:9001 \
  --name minio \

```
