HMPPS Prisoner Search

This README provides information on the prisoner search service. For the indexer service that keeps the search up-to-date from Prison systems (NOMIS) please see the indexer README.

The purpose of this service is to:

• API to provides searching of prisoner records in NOMIS via OpenSearch

Running

localstack is used to emulate the AWS OpenSearch service.

Running prisoner search in Docker

WE STRONGLY ADVISE, WHEN RUNNING LOCALLY, TO POINT AT SERVICES IN THE T3/DEV ENVIRONMENT

Since search has a number of dependencies that themselves have dependencies, it is recommended that when running locally you point mostly at services running in T3. The exception is pointing at localstack for AWS services, but HMPPS Auth, prison-api, incentives services are best used directly on T3 dev environment. The docker-compose.yml file is provided as reference but the dependencies of dependencies are not shown and are subject to change. To run against T3 dependencies the environment variables as shown in the helm_deploy/values-dev.yaml file for paths can be used. Personal client credentials for the T3 services can be obtained from the HMPPS Auth team with the appropriate roles.

To start up localstack and other dependencies with prisoner search running in Docker too:

docker compose up localstack hmpps-auth prison-api restricted-patients hmpps-incentives-api hpsi-db

Once localstack has started then, in another terminal, run the following command to start prisoner search too:
```shell
docker-compose up hmpps-prisoner-search --detach

To check that it has all started correctly use docker ps.

Running prisoner search in IntelliJ or on the command line

To start up localstack and other dependencies with prisoner search running in IntelliJ:

docker compose up --scale hmpps-prisoner-search=0 --scale hmpps-prisoner-search-indexer=0

To then run prisoner search from the command line:

SPRING_PROFILES_ACTIVE=dev ./gradlew bootRun

Alternatively create a Spring Boot run configuration with active profile of dev and main class uk.gov.justice.digital.hmpps.prisonersearch.search.HmppsPrisonerSearch.

Running the tests

If just running the tests then the following will just start localstack as the other dependencies are mocked out:

docker compose -f docker-compose-test.yml up

Then the following command will run all the tests:

./gradlew test

Raw OpenSearch access

Access to the raw OpenSearch indexes is only possible from the Cloud Platform hmpps-prisoner-search family of namespaces.

First step is to setup a port-forward on local port 19200:

NAMESPACE=hmpps-prisoner-search-dev && kubectl -n $NAMESPACE port-forward $(kubectl -n $NAMESPACE get pods | grep opensearch-proxy-cloud-platform | grep Running | head -1 | awk '{print $1}') 19200:8080

Then the following http command will return a list all indexes e.g.:

http http://localhost:19200/_cat/indices
