</cli-modifiers>

```bash
elastic stack es ccr put-auto-follow-pattern \
  --remote-cluster <remote-cluster> \
  --name <name> \
  [options]
```

Create or update auto-follow patterns.
**Behaviour flags:**
`--dry-run` — validate all inputs and exit without performing any action

## Options

<definitions>
  <definition term="--remote-cluster string required">
    The remote cluster containing the leader indices to match against.
  </definition>
  <definition term="--name string required">
    The name of the collection of auto-follow patterns.
  </definition>
  <definition term="--master-timeout string">
    Period to wait for a connection to the master node.
  </definition>
  <definition term="--follow-index-pattern string">
    The name of follower index. The template {{leader_index}} can be used to derive the name of the follower index from the name of the leader index. When following a data stream, use {{leader_index}}; CCR does not support changes to the names of a follower data stream’s backing indices.
  </definition>
  <definition term="--leader-index-patterns string[]">
    An array of simple index patterns to match against indices in the remote cluster specified by the remote_cluster field.
    **Repeatable:** pass `--leader-index-patterns` multiple times to supply more than one value
  </definition>
  <definition term="--leader-index-exclusion-patterns string[]">
    An array of simple index patterns that can be used to exclude indices from being auto-followed. Indices in the remote cluster whose names are matching one or more leader_index_patterns and one or more leader_index_exclusion_patterns won’t be followed.
    **Repeatable:** pass `--leader-index-exclusion-patterns` multiple times to supply more than one value
  </definition>
  <definition term="--max-outstanding-read-requests number">
    The maximum number of outstanding reads requests from the remote cluster.
  </definition>
  <definition term="--settings string">
    Settings to override from the leader index. Note that certain settings can not be overrode (e.g., index.number_of_shards).
  </definition>
  <definition term="--max-outstanding-write-requests number">
    The maximum number of outstanding reads requests from the remote cluster.
  </definition>
  <definition term="--read-poll-timeout string">
    The maximum time to wait for new operations on the remote cluster when the follower index is synchronized with the leader index. When the timeout has elapsed, the poll for operations will return to the follower so that it can update some statistics. Then the follower will immediately attempt to read from the leader again.
  </definition>
  <definition term="--max-read-request-operation-count number">
    The maximum number of operations to pull per read from the remote cluster.
  </definition>
  <definition term="--max-read-request-size string">
    The maximum size in bytes of per read of a batch of operations pulled from the remote cluster.
  </definition>
  <definition term="--max-retry-delay string">
    The maximum time to wait before retrying an operation that failed exceptionally. An exponential backoff strategy is employed when retrying.
  </definition>
  <definition term="--max-write-buffer-count number">
    The maximum number of operations that can be queued for writing. When this limit is reached, reads from the remote cluster will be deferred until the number of queued operations goes below the limit.
  </definition>
  <definition term="--max-write-buffer-size string">
    The maximum total bytes of operations that can be queued for writing. When this limit is reached, reads from the remote cluster will be deferred until the total bytes of queued operations goes below the limit.
  </definition>
  <definition term="--max-write-request-operation-count number">
    The maximum number of operations per bulk write request executed on the follower.
  </definition>
  <definition term="--max-write-request-size string">
    The maximum total bytes of operations per bulk write request executed on the follower.
  </definition>
  <definition term="--error-trace">
    When set to `true` Elasticsearch will include the full stack trace of errors
    when they occur.
  </definition>
  <definition term="--filter-path string">
    Comma-separated list of filters in dot notation which reduce the response
    returned by Elasticsearch.
    **Repeatable:** pass `--filter-path` multiple times to supply more than one value
  </definition>
  <definition term="--human">
    When set to `true` will return statistics in a format suitable for humans.
    For example `"exists_time": "1h"` for humans and
    `"exists_time_in_millis": 3600000` for computers. When disabled the human
    readable values will be omitted. This makes sense for responses being consumed
    only by machines.
  </definition>
  <definition term="--pretty">
    If set to `true` the returned JSON will be "pretty-formatted". Only use
    this option for debugging only.
  </definition>
  <definition term="--input-file string">
    path to a JSON file to use as command input
  </definition>
  <definition term="--dry-run">
    validate all inputs and exit without performing any action (preview changes without applying them)
  </definition>
</definitions>


## Global Options
