==== Configuring SSL parameters
|
||||
|
||||
Reindex from remote supports configurable SSL settings. These must be
|
||||
specified in the `elasticsearch.yml` file, with the exception of the
|
||||
secure settings, which you add in the Elasticsearch keystore.
|
||||
It is not possible to configure SSL in the body of the `_reindex` request.
|
||||
|
||||
The following settings are supported:
|
||||
|
||||
`reindex.ssl.certificate_authorities`::
|
||||
List of paths to PEM encoded certificate files that should be trusted.
|
||||
You cannot specify both `reindex.ssl.certificate_authorities` and
|
||||
`reindex.ssl.truststore.path`.
|
||||
|
||||
`reindex.ssl.truststore.path`::
|
||||
The path to the Java Keystore file that contains the certificates to trust.
|
||||
This keystore can be in "JKS" or "PKCS#12" format.
|
||||
You cannot specify both `reindex.ssl.certificate_authorities` and
|
||||
`reindex.ssl.truststore.path`.
|
||||
|
||||
`reindex.ssl.truststore.password`::
|
||||
The password to the truststore (`reindex.ssl.truststore.path`).
|
||||
This setting cannot be used with `reindex.ssl.truststore.secure_password`.
|
||||
|
||||
`reindex.ssl.truststore.secure_password` (<<secure-settings,Secure>>)::
|
||||
The password to the truststore (`reindex.ssl.truststore.path`).
|
||||
This setting cannot be used with `reindex.ssl.truststore.password`.
|
||||
|
||||
`reindex.ssl.truststore.type`::
|
||||
The type of the truststore (`reindex.ssl.truststore.path`).
|
||||
Must be either `jks` or `PKCS12`. If the truststore path ends in ".p12", ".pfx"
|
||||
or "pkcs12", this setting defaults to `PKCS12`. Otherwise, it defaults to `jks`.
|
||||
|
||||
`reindex.ssl.verification_mode`::
|
||||
Indicates the type of verification to protect against man in the middle attacks
|
||||
and certificate forgery.
|
||||
One of `full` (verify the hostname and the certificate path), `certificate`
|
||||
(verify the certificate path, but not the hostname) or `none` (perform no
|
||||
verification - this is strongly discouraged in production environments).
|
||||
Defaults to `full`.
|
||||
|
||||
`reindex.ssl.certificate`::
|
||||
Specifies the path to the PEM encoded certificate (or certificate chain) to be
|
||||
used for HTTP client authentication (if required by the remote cluster)
|
||||
This setting requires that `reindex.ssl.key` also be set.
|
||||
You cannot specify both `reindex.ssl.certificate` and `reindex.ssl.keystore.path`.
|
||||
|
||||
`reindex.ssl.key`::
|
||||
Specifies the path to the PEM encoded private key associated with the
|
||||
certificate used for client authentication (`reindex.ssl.certificate`).
|
||||
You cannot specify both `reindex.ssl.key` and `reindex.ssl.keystore.path`.
|
||||
|
||||
`reindex.ssl.key_passphrase`::
|
||||
Specifies the passphrase to decrypt the PEM encoded private key
|
||||
(`reindex.ssl.key`) if it is encrypted.
|
||||
Cannot be used with `reindex.ssl.secure_key_passphrase`.
|
||||
|
||||
`reindex.ssl.secure_key_passphrase` (<<secure-settings,Secure>>)::
|
||||
Specifies the passphrase to decrypt the PEM encoded private key
|
||||
(`reindex.ssl.key`) if it is encrypted.
|
||||
Cannot be used with `reindex.ssl.key_passphrase`.
|
||||
|
||||
`reindex.ssl.keystore.path`::
|
||||
Specifies the path to the keystore that contains a private key and certificate
|
||||
to be used for HTTP client authentication (if required by the remote cluster).
|
||||
This keystore can be in "JKS" or "PKCS#12" format.
|
||||
You cannot specify both `reindex.ssl.key` and `reindex.ssl.keystore.path`.
|
||||
|
||||
`reindex.ssl.keystore.type`::
|
||||
The type of the keystore (`reindex.ssl.keystore.path`). Must be either `jks` or `PKCS12`.
|
||||
If the keystore path ends in ".p12", ".pfx" or "pkcs12", this setting defaults
|
||||
to `PKCS12`. Otherwise, it defaults to `jks`.
|
||||
|
||||
`reindex.ssl.keystore.password`::
|
||||
The password to the keystore (`reindex.ssl.keystore.path`). This setting cannot be used
|
||||
with `reindex.ssl.keystore.secure_password`.
|
||||
|
||||
`reindex.ssl.keystore.secure_password` (<<secure-settings,Secure>>)::
|
||||
The password to the keystore (`reindex.ssl.keystore.path`).
|
||||
This setting cannot be used with `reindex.ssl.keystore.password`.
|
||||
|
||||
`reindex.ssl.keystore.key_password`::
|
||||
The password for the key in the keystore (`reindex.ssl.keystore.path`).
|
||||
Defaults to the keystore password. This setting cannot be used with
|
||||
`reindex.ssl.keystore.secure_key_password`.
|
||||
|
||||
`reindex.ssl.keystore.secure_key_password` (<<secure-settings,Secure>>)::
|
||||
The password for the key in the keystore (`reindex.ssl.keystore.path`).
|
||||
Defaults to the keystore password. This setting cannot be used with
|
||||
`reindex.ssl.keystore.key_password`.
