OpenLMIS Stock Management Service¶
This service allows users to create/update stock cards and stock movements.
- Java 1.8+
- Docker 1.11+
- Docker Compose 1.6+
All other dependencies, such as Java, are delivered automatically via the Docker image. It is unnecessary to install them locally to run the service, though often helpful to do so for the sake of development. See the Tech section of openlmis/dev for a list of these optional dependencies.
- Fork/clone this repository from GitHub.
git clone https://github.com/OpenLMIS/openlmis-stockmanagement.git
- Add an environment file called
.envto the root folder of the project, with the required project settings and credentials. For a starter environment file, you can use this one. e.g.
curl -LO https://raw.githubusercontent.com/OpenLMIS/openlmis-config/master/.env
- Develop w/ Docker by running
docker-compose run --service-ports stockmanagement. See Developing w/ Docker.
- You should now be in an interactive shell inside the newly created development
environment, start the Service with:
- Go to
http://<yourDockerIPAddress>:8080/to see the service name and version. Note that you can determine yourDockerIPAddress by running
- Go to
http://<yourDockerIPAddress>:8080/stockmanagement/docsto see the APIs.
Gradle is our usual build tool. This template includes common tasks that most Services will find useful:
cleanto remove build artifacts
buildto build all source.
build, after building sources, also runs unit tests. Build will be successful only if all tests pass.
generateMigration -PmigrationName=<yourMigrationName>to create a “blank” database migration file. The file will be generated under
src/main/resources/db/migration. Put your migration SQL into it.
testto run unit tests
integrationTestto run integration tests
sonarqubeto execute the SonarQube analysis.
The test results are shown in the console.
While Gradle is our usual build tool, OpenLMIS v3+ is a collection of Independent Services where each Gradle build produces 1 Service. To help work with these Services, we use Docker to develop, build and publish these.
OpenLMIS utilizes Docker to help with development, building, publishing and deployment of OpenLMIS Services. This helps keep development to deployment environments clean, consistent and reproducible and therefore using Docker is recommended for all OpenLMIS projects.
To enable development in Docker, OpenLMIS publishes a couple Docker Images:
- openlmis/dev - for Service development. Includes the JDK & Gradle plus common build tools.
- openlmis/postgres - for quickly standing up a shared PostgreSQL DB
In addition to these Images, each Service includes Docker Compose instructions to:
- standup a development environment (run Gradle)
- build a lean image of itself suitable for deployment
- publish its deployment image to a Docker Repository
Launches into shell with Gradle & JDK available suitable for building Service. PostgreSQL connected suitable for testing. If you run the Service, it should be available on port 8080.
Before starting the development environment, make sure you have a
.env file as outlined in the
Quick Start instructions.
> docker-compose run --service-ports stockmanagement $ gradle clean build $ gradle bootRun
The specialized docker-compose.builder.yml is geared toward CI and build servers for automated building, testing and docker image generation of the service.
Before building the deployment image, make sure you have a
.env file as outlined in the Quick
> docker-compose -f docker-compose.builder.yml run builder > docker-compose -f docker-compose.builder.yml build image
Publish to Docker Repository¶
A brief overview of the purpose behind each docker related file
Dockerfile: build a deployment ready image of this service suitable for publishing.
docker-compose.yml: base docker-compose file. Defines the basic composition from the perspective of working on this singular vertical service. These aren’t expected to be used in the composition of the Reference Distribution.
docker-compose.override.yml: extends the
docker-compose.ymlbase definition to provide for the normal usage of docker-compose inside of a single Service: building a development environment. Wires this Service together with a DB for testing, a gradle cache volume and maps tomcat’s port directly to the host. More on how this file works: https://docs.docker.com/compose/extends/
docker-compose.builder.yml: an alternative docker-compose file suitable for CI type of environments to test & build this Service and generate a publishable/deployment ready Image of the service.
docker-compose.prod.yml: Docker-compose file suitable for production. Contains nginx-proxy image and virtual host configuration of each service.
- Enter desired
VIRTUAL_HOSTfor each service in the
- Start up containers
> docker-compose -f docker-compose.yml -f docker-compose.prod.yml up
- The application should be available at port 80.
Logging is implemented using SLF4J in the code, Logback in Spring Boot, and routed to an external Syslog server. There is a default configuration XML (logback.xml) in the resources folder. To configure the log level for the development environment, simply modify the logback.xml to suit your needs.
Configuring log level for a production environment is a bit more complex, as the code has already been packaged into a Spring Boot jar file. However, the default log configuration XML can be overridden by setting the Spring Boot logging.config property to an external logback.xml when the jar is executed. The container needs to be run with a JAVA_OPTS environment variable set to a logback.xml location, and with a volume with the logback.xml mounted to that location. Some docker compose instructions have been provided to demonstrate this.
- Build the deployment image. (See Build Deployment Image)
- Get a logback.xml file and modify it to suit your log level configuration.
docker-compose.builder.ymlto point to your logback.xml location. a. Under
volumes, where it shows two logback.xml locations separated by a colon, change the location before the colon.
- Run the command below.
> docker-compose -f docker-compose.builder.yml run --service-ports stockmanagement
Internationalization is implemented by the definition of two beans found in the Application
class, localeResolver and messageSource. (Alternatively, they could be defined in an application
context XML file.) The localeResolver determines the locale, using a cookie named
lang in the
en (for English) as the default. The messageSource determines where to find the
Note there is a custom message source interface, ExposedMessageSource, with a corresponding class ExposedMessageSourceImpl. These provide a method to get all the messages in a locale-specific message file.
See the MessageController class for examples on how to get messages.
Additionally, Transifex has been integrated into the development and
build process. In order to sync with the project’s resources in Transifex, you must provide
values for the following keys:
For the development environment in Docker, you can sync with Transifex by running the
sync_transifex.sh script. This will upload your source messages file to the Transifex project
and download translated messages files.
The build process has syncing with Transifex seamlessly built-in.
To debug the Spring Boot application, use the
$ gradle bootRun --debug-jvm
This will enable debugging for the application, listening on port 5005, which the container has exposed. Note that the process starts suspended, so the application will not start up until the debugger has connected.
