Developing ECM in the Broad Institute Environment

This document describes the nuts and bolts of developing on ECM in the Broad environment. Processes here rely on access to the Broad Vault server to get secrets and to the Broad Artifactory server to read and write libraries. There are dependencies on Broad Dev Ops github repositories and practices. Some of those are locked down, because the Broad deployment of Terra needs to maintain a FedRamp approval level in order to host US Government data.

Setup

Prerequisites:

  • Install Postgres 13: https://www.postgresql.org/download/

    • The app may be easier, just make sure to download the right version. It'll manage things for you and has a useful menulet where the server can be turned on and off. Don't forget to create a server if you go this route.

  • Install Adoptium Java 17 (Temurin). Here's an easy way on Mac, using jEnv to manage the active version:

    brew install jenv
# follow postinstall instructions to activate jenv...

# to add previously installed versions of Java to jEnv, list them:
# /usr/libexec/java_home -V
# and then add them:
# jenv add /Library/Java/JavaVirtualMachines/<JAVA VERSION HERE>/Contents/Home

brew install homebrew/cask-versions/temurin17

jenv add /Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home

NOTE: You may encounter issues with the application when running an unexpected version of Java. So make sure you are running Temurin-17 as specified above.

Database Configuration

ECM relies on a Postgresql database server. There are two options for running the Postgres server:

  • Manual setup: Setup Postgres using whatever method you like.
  • Convenient app setup: Install the convenient app, and create a database called ecm.

Initialize your database:

psql -h 127.0.0.1 -U postgres -f ./common/postgres-init.sql

N.B. If you used the convenient app, you should run psql as /Applications/Postgres.app/Contents/Versions/latest/bin/psql

IntelliJ Setup

  1. Open the repo normally (File > New > Project From Existing Sources). Select the folder, and then select Gradle as the external model.
  2. In project structure (the folder icon with a little tetromino over it in the upper right corner), make sure the project SDK is set to Java 17. If not, IntelliJ should detect it on your system in the dropdown, otherwise click "Add JDK..." and navigate to the folder from the last step.
  3. Set up google-java-format. We use the spotless checker to force code to a standard format. Installing the IntelliJ plug-in and library makes it easier to get it in the right format from the start.
  4. See some optional tips below in the "Tips" section.

Running

Human-Readable Logging

To enable human-readable logging, add ECM_LOG_APPENDER=Console-Standard to your env.

Running Tests

Unit tests will run on build. Integration tests can be run by following the instructions in the integration README.

Running ECM Locally

Run in IntelliJ (recommended) or use the command line:

./render_config.sh # only when building ECM for the first time
source ${PWD}/service/src/main/resources/rendered/secrets.env
cd service
../gradlew bootRun

Then navigate to the Swagger: http://localhost:8080/

Run Pact Tests

To run the Pact tests, run the following:

export PACT_BROKER_URL="pact-broker.dsp-eng-tools.broadinstitute.org"
export PACT_PROVIDER_COMMIT="$(git rev-parse HEAD)"
export PACT_PROVIDER_BRANCH="$(git rev-parse --abbrev-ref HEAD)"
export PACT_BROKER_USERNAME="$(vault read -field=basic_auth_read_only_username secret/dsp/pact-broker/users/read-only)"
export PACT_BROKER_PASSWORD="$(vault read -field=basic_auth_read_only_password secret/dsp/pact-broker/users/read-only)"

./gradlew verifyPacts

Tips

  • Check out gdub, it'll save you typing ./gradlew over and over, and also takes care of knowing when you're not in the root directory so you don't have to figure out the appropriate number of ../s.
  • In IntelliJ, instead of running the local server with bootRun, use the ExternalCredsApplication Spring Boot configuration that IntelliJ auto-generates. To edit it, click on it (in the upper right of the window), and click Edit Configurations.
    • For readable logs, put human-readable-logging in the Active Profiles field.
