Learn about configurations >

• api-port | int

  Default: 9200

  Port number to listen for HTTP API connections.

• deployment-label | string

  Label for the deployment type. A label that will be used in the installation path of the payload that indicates its type. For example "devel", "staging" or "production".

• extra_packages | string

  Space separated list of extra deb packages to install.

• install_keys | string

  List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.

• install_sources | string

  List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.

• max-open-files | int

  Default: 65536

  The maximum number of open files allowed to elasticsearch. Setting this to less than 65536 may prevent elasticsearch from starting.

• os-auth-url | string

  Openstack authentication URL for use with swift sources.

• os-auth-version | string

  Default: 2

  Openstack authentication protocol version to use when authenticating swift sources.

• os-key | string

  Key/password to use when authenticating swift sources.

• os-options | string

  Additional openstack parameters to use when authenticating swift sources. The value must be a YAML encoded map of additional options.

• os-user | string

  Username to use when authenticating swift sources.

• package_status | string

  Default: install

  The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".

• peer-port | int

  Default: 9300

  Port number to listen for peer transport connections.

• source | string

  Default: https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.3.0.tar.gz

  URL of the service archive. Supported URL types are file, http, https and swift. If the URL has no scheme then the source is taken to be a file path. If it is a relative path it will be resolved relative to $CHARM_DIR/files/. Swift URLs take the form swift:/$container/$object. If a swift URL is used then the os-auth-url, os-key & os-user parameters must be specified to enable the object to be downloaded from the container.

• vm-max-map-count | int

  Default: 262144

  The maximum number memory mapped files supported by the system. This is the vm.max_map_count sysctl. Setting this to less than 262144 may prevent elasticsearch from starting.
