Adding support to disable SSL based connection to Elastic Search through a config parameter.

Support HTTP connection to Elastic search with default being HTTPS.

Status

• Proposed
• Trialing
• Under review
• Approved
• Retired

Context & Scope

Currently connection to elastic search is mandated to be with SSL connection only. This is causing for a local setup development blocker, as it needs SSL enabled elastic search setup locally.

Decision

Rationale

Resolution

• Allow for user to explicitly switch off the use of HTTPS when making connection to elastic search endpoint.
• The default is still with SSL enforced. Its optional for anyone who wants to switch off to switch off SSL.
• This is achieved by doing changes at these places
  1. Core-lib changes
     • Making changes in the core lib, by adding logic to the create of the elasticsearch client that provides way for getting the client with SSL and TLS not mandated.
     • The setting of elastic search that enables/disables SSL has a default of having SSL "enabled".
     • The setting lies in line with where the elastic creds are stored currently.
     • The way to fetch values by default value is added.
  2. Indexer changes
     • The changes are mostly to the test core.
     • Ability to fetch the value of the config for SSL enablement with default as SSL enabled.
     • Updating the client creation to define the scheme based on the flag that is set.
  3. Search changes
     • The changes are similar to the indexer changes as at both places the test cores have a copy kind of notion for the ElasticUtils file.

Next refactor (nice to have): Better to get the test core common functional items to a core test lib so as to reduce the multiple places of changes.

Tradeoff Analysis - Input to decision

Alternatives and implications

• This step could be an intermediate one for moving to profile based spring boot application launch.
• Profiles would help us segregate and override the required env variables based on profile selection during launch of service.
• Bringing profiles in one change is a larger change.
