Environment Variables:

Variable Name

Description

1

OPENMRS_IMAGE_TAG

This value tells which image version to be used for Bahmni OpenMRS. List of tags can be found at bahmni/openmrs - Tags .

2

OPENMRS_DB_NAME

Database name for OpenMRS application

3

OPENMRS_DB_HOST

Host name of the MySQL Database server.

4

OPENMRS_DB_USERNAME

Username of the OpenMRS Database. OpenMRS container will create a database user with this credential.

5

OPENMRS_DB_PASSWORD

Password of the OpenMRS Database. OpenMRS container will create a database user with this credential.

6

OPENMRS_DB_CREATE_TABLES

Takes either true/false. Setting this to true, OpenMRS creates the tables necessary or running the application. Note: Set this to true only when you are running with an empty MySQL Database.

7

OPENMRS_DB_AUTO_UPDATE

Takes either true/false. When set to true, the migrations are run and schema is kept up to date.

8

OPENMRS_MODULE_WEB_ADMIN

Takes either true/false. Settings this to true allows you to manage OpenMRS Modules through the Web UI. It is recommended to set to false in production.

9

OPENMRS_DEBUG

Takes either true/false. Enables the debug mode of OpenMRS

10

OPENMRS_UPLOAD_FILES_PATH

This variable can be specified with a directory of the host machine where the uploaded files from OpenMRS needs to be stored. Defaults to openmrs-uploads directory in the docker-compose directory itself.

11

MYSQL_ROOT_PASSWORD

This is the root password for MySQL Database Server used by OpenMRS DB service.

12

OPENMRS_DB_IMAGE_NAME

This is used to set the type of database container to start up. You can use mysql:5.6 and set OPENMRS_DB_CREATE_TABLES to true to start with fresh setup with no data loaded.

Login into OpenMRS Admin UI & First-time steps

To check if OpenMRS container is ready, see the OpenMRS Logs and ensure you see this line in the tomcat logs:

Code Block
INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ["http-nio-8080"]
INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 119674 ms

In your browser, go to the following URL: https://localhost/openmrs/ (Creds: superman/Admin123).

If this is your FIRST TIME login into OpenMRS, you will need to create Search Index. Perform these steps:

  1. Login into OpenMRS Admin UI.

  2. Go to Administration → Search Index (https://localhost/openmrs/admin/maintenance/searchIndex.htm)

  3. Click on “Rebuild Search Index”. This should take less than 2 minutes.

  4. Once done, you can now use OpenMRS and Bahmni.

View OpenMRS Logs

Code Block
# To see OpenMRS logs (from the appropriate docker-compose sub-folder)
docker-compose logs openmrs -f

# Another way
docker logs <openmrs-container-id> -f

# To get container ID of all containers 
docker ps

Debugging OpenMRS Application

Since OpenMRS is running on Tomcat, remote debugging can be enabled and can be connected with IDE supporting remote debugging.(Eclipse, Intellij IDEA etc.)

  1. Enable debugging by uncommenting & setting OMRS_DEV_DEBUG_PORT to some port (e.g 8000) in the .env and docker-compose files

  2. Now remote debugging for OpenMRS is exposed on port OMRS_DEV_DEBUG_PORT in your local machine.

  3. Now you can follow the IDE configuration to setup remote debugging using host as localhost and port as the value of OMRS_DEV_DEBUG_PORT.

  4. For example in Intellij IDEA navigate to Run -> Edit Configurations. In the dialog box click on + icon to create a new config and select Remote JVM Debug. Fill in the host,port and name and click Apply. Now you can use the debugger.

Note

Make sure to disable debugging if you are running in a Production Environment

Setting up a fresh OpenMRS Instance

By default, the configuration of openmrs and openmrsdb services are set to load demo data from a backup file. If you want to start the installation with a fresh schema, set OPENMRS_DB_CREATE_TABLES to true and then set OPENMRS_DB_IMAGE_NAME to mysql:5.6. Now when start the schema will be created by liquibase migrations of OpenMRS and other OMODS loaded.

Apache Tomcat Environment Variables

To set CATALINA_HOME and JAVA_OPTS or other Environment variables used by the Tomcat startup scripts, set the value of these variables, here. The values of CATALINA_HOME and JAVA_OPTS are set as

Code Block
JAVA_OPTS="$OMRS_JAVA_SERVER_OPTS"
CATALINA_OPTS="${OMRS_JAVA_MEMORY_OPTS} -DOPENMRS_INSTALLATION_SCRIPT=${OMRS_SERVER_PROPERTIES_FILE} -DOPENMRS_APPLICATION_DATA_DIRECTORY=${OMRS_DATA_DIR}/"

Values of OMRS_SERVER_PROPERTIES_FILE by default is set to /openmrs/openmrs-server.properties and OMRS_DATA_DIR set to /openmrs/data

Configuring Database connection pool max size

The number of maximum connections that would be made from openmrs to the database instance can be controlled.

There is a variable called as OMR_C3P0_MAX_SIZE in the env file with the default value of 50. If you have a smaller instance of database which is not capable of handling this many connections then this value can be decreased accordingly. Also if you have more number of simultaneous users you can increase this value based on database instance capacity. Once you update the value, recreate the container by running docker compose up -d . More about performance baselining can be found here.
