Install and configure a remote Elasticsearch instance
This page describes how to provision a remote Elasticsearch instance to work with Bitbucket Data Center.
Bitbucket Data Center requires a remote Elasticsearch instance, as it is not bundled or installed for Bitbucket Data Center.
Bitbucket Data Center can have only one remote connection to Elasticsearch for your cluster. This may be a standalone Elasticsearch installation or a clustered installation behind a load balancer.
For details of about how Bitbucket uses Elasticsearch, including troubleshooting tips and frequently asked questions, see the page Administer code search.
Step 1: Install Elasticsearch on a remote machine
We don't provide specific instructions for installing Elasticsearch, but a good place to start is the Elasticsearch (5.5) installation instructions. Elastic provides installation packages in several different formats here. Note that the authentication plugin – Buckler, described within the Secure Elasticsearch section – only supports versions 5.5 of Elasticsearch. Refer to the Supported platforms - Additional Tools section to see the current Elasticsearch release we support.
Step 2: Configure Elasticsearch
elasticsearch.yml file contains configuration details for your Elasticsearch instance.
To configure your remote Elasticsearch instance
- Locate the
elasticsearch.ymlfile within the configuration directory of your Elasticsearch (5.5) instance.
Add these parameters to your
action.auto_create_index: false network.host: 0.0.0.0Third party plugins, such as Elastic's Shield plugin, may require specific exceptions to be set for
action.auto_create_index. Consult your provider's documentation for more information.
Step 3: Secure Elasticsearch
You need to secure access to your remote Elasticsearch instance with a username and password. We recommend securing your remote Elasticsearch instance with a security plugin that requires anyone connecting to it provides authentication credentials. Atlassian provides a free plugin called Buckler for this purpose. Bitbucket Server also supports authentication to Elasticsearch through other plugins that provide basic authentication, like Elastic's Shield plugin.
To secure your remote Elasticsearch instance with the Buckler plugin
Copy the Buckler plugin URL to your clipboard:
|Elasticsearch 5.5.3||Buckler 1.0.4 for ES 5.5.3|
Install the plugin onto your remote Elasticsearch instance using the plugin helper in the Elasticsearch
cd /path/to/elasticsearch/bin ./plugin install -b <link from table above>
Configure basic authentication for Bitbucket to access your remote Elasticsearch installation. We strongly suggest enabling basic HTTP authentication, at minimum, for a remote Elasticsearch instance working with Bitbucket Data Center.
- Create a directory called
elasticsearch/config/bucklerdirectory, create a file named
When installing using rpm or deb file
The location of your configuration directory varies depending on how you installed Elasticsearch. For rpm/deb installations the location is typically in
if the file is placed in the wrong location Buckler does not enforce any permissions, so your instance/cluster is not secure.
Enable Buckler: at this point there are no configuration properties within
buckler.yml, so the features of the Buckler plugin are disabled.
To enable the Buckler for basic HTTP authentication, you add these properties to the file, creating a username and password that Bitbucket will use to access Elasticsearch (configured in a later step).elasticsearch/config/buckler/buckler.yml
auth.basic.http.enabled: true auth.basic.username: <username> auth.basic.password: <password>Here's an example config which enables every feature...
auth.basic.http.enabled: true auth.basic.tcp.enabled: true auth.basic.username: admin auth.basic.password: basicpassword tls.http.enabled: true tls.tcp.enabled: true tls.keystore.path: /path/to/keystore tls.keystore.password: keystorepasswordHere's an explanation of all the parameters you can configure...
Parameter Value Description
Enables basic authentication for HTTP.
Enables basic authentication for TCP.
Username to access Elasticsearch instance.
Password to access Elasticsearch instance.
Enables TLS for HTTP.
Enables TLS for TCP.
Absolute filesystem path to the keystore.
Password for accessing the keystore.
If you enable TLS, the following block will need to be added to
http.type: buckler transport.type: buckler
This is relevant for Buckler version 1.0.1 onwards.
- Start your remote Elasticsearch instance. See Elasticsearch (5.5) documentation for specific instructions.
Step 4: Connect Elasticsearch to Bitbucket
Once you've configured your Elasticsearch instance you then need to connect it to Bitbucket.
To configure your remote Elasticsearch instance using the
bitbucket.propertiesfile, it cannot be edited later from the admin UI. Any changes that need to be made to the Elasticsearch configuration must be made within the
- Locate the
bitbucket.propertiesfile in the
<Bitbucket home directory>/shareddirectory.
Add the details of your Elasticsearch instance (created in step 3.3 above):<Bitbucket home directory>/shared/bitbucket.properties
plugin.search.elasticsearch.baseurl=http://localhost:9200/ plugin.search.elasticsearch.username=<username> plugin.search.elasticsearch.password=<password>
- Save and close the file.
Start Bitbucket Server without starting the bundled Elasticsearch instance.
Your remote Elasticsearch instance is now configured to work with Bitbucket Server.
