6.3.0 Release

6.3.0 - 2018/06/18

Breaking changes

Elasticsearch 6.3 includes several big changes that are reflected in this role.
When upgrading from module versions prior to 6.3, there are a number of upgrade considerations to take into account:

• This role defaults to the upstream package repositories, which now include X-Pack bundled by default. To preserve previous behavior which does not include X-Pack be sure to explicitly set es_enable_xpack: false which will install the elasticsearch-oss package.
• Great care has been taken in making sure that all upgrade paths work, however as always please take extra caution when upgrading and test in a non-production environment. New automated tests have been added to make sure that the following upgrade paths work:
  • oss to oss
  • oss to xpack
  • xpack to xpack
• X-Pack configuration files which used to be in ${ES_PATH_CONF}/x-pack are now in ${ES_PATH_CONF}/. If you have any configuration files in this directory not managed by ansible you will need to move them manually.

Features

• Integration testing has been refactored in #457. This removed a lot of duplicate tests and added new tests to make sure all upgrade paths work.
• It is now possible to test elasticsearch snapshot builds by setting es_use_snapshot_release to true

Fixes

• Installing es_plugins from custom urls is now idempotent. Previously the plugin name was being compared to the url which meant it would be reinstalled every time ansible was run because they didn't match
