The 'http' command guides you through the process of generating certificates
for use on the HTTP (Rest) interface for Elasticsearch.
...
...
If you choose not to generate a CSR, this tool will generate a new certificate
for you. That certificate will be signed by a CA under your control. This is a
quick and easy way to secure your cluster with TLS, but you will need to
configure all your clients to trust that custom CA.

If you have an existing CA certificate and key, then you can use that CA to
sign your new http certificate. This allows you to use the same CA across
multiple Elasticsearch clusters which can make it easier to configure clients,
and may be easier for you to manage.

If you do not have an existing CA, one will be generated for you.

However, if you do not have a common domain name, and you expect to add
additional nodes to your cluster in the future, then you should generate a
certificate per node so that you can more easily generate new certificates when
you provision new nodes.

You should list every hostname and variant that people will use to connect to
your cluster over http.
Do not list IP addresses here, you will be asked to enter them later.

If you wish to use a wildcard certificate (for example *.es.example.com) you
can enter that here.

certificate.

If you do not have fixed IP addresses, or not wish to support direct IP access
to your cluster then you can just press <ENTER> to skip this step.

## Elasticsearch HTTP Certificate Utility

The 'http' command guides you through the process of generating certificates
for use on the HTTP (Rest) interface for Elasticsearch.
...
...
If you choose not to generate a CSR, this tool will generate a new certificate
for you. That certificate will be signed by a CA under your control. This is a
quick and easy way to secure your cluster with TLS, but you will need to
configure all your clients to trust that custom CA.

multiple Elasticsearch clusters which can make it easier to configure clients,
and may be easier for you to manage.

If you do not have an existing CA, one will be generated for you.

The 'http' command guides you through the process of generating certificates
for use on the HTTP (Rest) interface for Elasticsearch.

...
If you choose not to generate a CSR, this tool will generate a new certificate
for you. That certificate will be signed by a CA under your control. This is a
quick and easy way to secure your cluster with TLS, but you will need to
configure all your clients to trust that custom CA.

If you have an existing CA certificate and key, then you can use that CA to
sign your new http certificate. This allows you to use the same CA across
multiple Elasticsearch clusters which can make it easier to configure clients,
and may be easier for you to manage.

If you do not have an existing CA, one will be generated for you.

Certificate signing requests have been written to /usr/share/elasticsearch/kb01.zip

This file should be properly secured as it contains the private keys for all

After unzipping the file, there will be a directory for each instance containing
the certificate signing request and the private key. Provide the certificate
signing requests to your certificate authority. Once you have received the
signed certificate, copy the signed certificate, key, and CA certificate to the
configuration directory of the Elastic product that they will be used for and
follow the SSL configuration instructions in the product guide.
