Add a --url option for elasticsearch-reset-password and elasticsearch-create-enrollment-token CLI Tools ( and any tools that would extend BaseRunAsSuperuserCommand ). The tools use CommandLineHttpClient internally, which tries its best to deduce the URL of the local node based on the configuration but there are certain cases where it either fails or returns an unwanted result. Concretely: - CommandLineHttpClient#getDefaultURL will always return a URL with the port set to 9200, unless otherwise explicitly set in the configuration. When running multiple nodes on the same host, subsequent nodes get sequential port numbers after 9200 by default and this means that the CLI tool will always connect the first of n nodes in a given host. Since these tools depend on a file realm local user, requests to other nodes would fail - When an ES node binds and listens to many addresses, there can be the case that not all of the IP addresses are added as SANs in the certificate that is used for TLS on the HTTP layer. CommandLineHttpClient#getDefaultURL will pick an address based on a preference order but that address might not be in the SANs and thus all requests to the node would fail due to failed hostname verification. Manually setting `--url` to an appropriate value allows users to overcome these edge cases.

The `elasticsearch-create-enrollment-token` command creates enrollment tokens for
|
|
{es} nodes and {kib} instances.

=== Synopsis
|
|
|
|
[source,shell]
|
|
----
|
|
bin/elasticsearch-create-enrollment-token
|
|
[-f, --force] [-h, --help] [-E <KeyValuePair>] [-s, --scope] [--url]

|
|
=== Description
|
|
|
|
Use this command to create enrollment tokens, which you can use to enroll new
|
|
{es} nodes to an existing cluster or configure {kib} instances to communicate
|
|
with an existing {es} cluster that has security features enabled.
|
|
The command generates (and subsequently removes) a temporary user in the
|
|
<<file-realm,file realm>> to run the request that creates enrollment tokens.
|
|
IMPORTANT: You cannot use this tool if the file realm is disabled in your
|
|
`elasticsearch.yml` file.
|
|
|
|
This command uses an HTTP connection to connect to the cluster and run the user
|
|
management requests. The command automatically attempts to establish the connection
|
|
over HTTPS by using the `xpack.security.http.ssl` settings in
|
|
the `elasticsearch.yml` file. If you do not use the default configuration directory,
|
|
ensure that the `ES_PATH_CONF` environment variable returns the
|
|
correct path before you run the `elasticsearch-create-enrollment-token` command. You can
|
|
override settings in your `elasticsearch.yml` file by using the `-E` command
|
|
option. For more information about debugging connection failures, see
|
|
<<trb-security-setup>>.

|
|
=== Parameters
|
|
|
|
`-E <KeyValuePair>`:: Configures a standard {es} or {xpack} setting.
|
|
|
|
`-f, --force`:: Forces the command to run against an unhealthy cluster.
|
|
|
|
`-h, --help`:: Returns all of the command parameters.
|
|
|
|
`-s, --scope`:: Specifies the scope of the generated token. Supported values are `node` and `kibana`.
|
|
|
|
`--url`:: Specifies the base URL (hostname and port of the local node) that the tool uses to submit API
|
|
requests to {es}. The default value is determined from the settings in your
|
|
`elasticsearch.yml` file. If `xpack.security.http.ssl.enabled` is set to `true`,
|
|
you must specify an HTTPS URL.

=== Examples
|
|
|
|
The following command creates an enrollment token for enrolling an {es} node into a cluster:
|
|
|
|
[source,shell]
|
|
----
|
|
bin/elasticsearch-create-enrollment-token -s node
|
|
----
|
|
|
|
The following command creates an enrollment token for enrolling a {kib} instance into a cluster.
|
|
The specified URL indicates where the elasticsearch-create-enrollment-token tool attempts to reach the
|
|
local {es} node:
|
|
|
|
[source,shell]
|
|
----
|
|
bin/elasticsearch-create-enrollment-token -s kibana --url "https://172.0.0.3:9200"
