civil-general-applications

Notes

JUnit 5 is now enabled by default in the project. Please refrain from using JUnit4 and use the next generation

After updated to OpenApi 3.0, the swagger interface now is at http://localhost:4550/swagger-ui/index.html

Building and deploying the application

Building the application

The project uses Gradle as a build tool. It already contains ./gradlew wrapper script, so there's no need to install gradle.

To build the project execute the following command:

  ./gradlew build

for running depdendency check locally ./gradlew --no-daemon --stacktrace -DdependencyCheck.failBuild=true -Dnvd.api.check.validforhours=24 -Danalyzer.central.enabled=false -Danalyzer.retirejs.enabled=false -Danalyzer.ossindex.enabled=false -Dnvd.api.key=<your_nvd_api_key> dependencyCheckAggregate

Running the application

Create the image of the application by executing the following command:

  ./gradlew assemble

Create docker image:

  docker-compose build

Run the distribution (created in build/install/civil-general-applications directory) by executing the following command:

  docker-compose up

This will start the API container exposing the application's port (set to 4550 in this template app).

In order to test if the application is up, you can call its health endpoint:

  curl http://localhost:4550/health

You should get a response similar to this:

  {"status":"UP","diskSpace":{"status":"UP","total":249644974080,"free":137188298752,"threshold":10485760}}

Alternative script to run application

To skip all the setting up and building, just execute the following command:

./bin/run-in-docker.sh

For more information:

./bin/run-in-docker.sh -h

Script includes bare minimum environment variables necessary to start api instance. Whenever any variable is changed or any other script regarding docker image/container build, the suggested way to ensure all is cleaned up properly is by this command:

docker-compose rm

It clears stopped containers correctly. Might consider removing clutter of images too, especially the ones fiddled with:

docker images

docker image rm <image-id>

There is no need to remove postgres and java or similar core images.

Other

Hystrix offers much more than Circuit Breaker pattern implementation or command monitoring. Here are some other functionalities it provides:

• Separate, per-dependency thread pools
• Semaphores, which you can use to limit the number of concurrent calls to any given dependency
• Request caching, allowing different code paths to execute Hystrix Commands without worrying about duplicating work

Adding Git Conventions

Include the git conventions.

• Make sure your git version is at least 2.9 using the git --version command
• Run the following command:

git config --local core.hooksPath .git-config/hooks

Once the above is done, you will be required to follow specific conventions for your commit messages and branch names.

If you violate a convention, the git error message will report clearly the convention you should follow and provide additional information where necessary.

Optional:

• Install this plugin in Chrome: https://github.com/refined-github/refined-github

  It will automatically set the title for new PRs according to the first commit message, so you won't have to change it manually.

  Note that it will also alter other behaviours in GitHub. Hopefully these will also be improvements to you.

In case of problems

1. Get in touch with your Technical Lead so that they can get you unblocked

2. If the rare eventuality that the above is not possible, you can disable enforcement of conventions using the following command

   git config --local --unset core.hooksPath

   Still, you shouldn't be doing it so make sure you get in touch with a Technical Lead soon afterwards.
