Run the ubuntu-docker-setup.sh script to setup java, gradle, docker and docker-compose. The script is specific to Ubuntu Bionic operating system but can be used as setup reference for other Linux systems as well. Compile and build all the microservices using gradle with below command. For now ignore the tests with "-x test" as this is still work in progress. All the password variables in docker-compose.yml file are read from below system environment variables. Replace the below shell variables with corresponding password values to be used by individual services. If no value is provided for the below password variables then their value is treated as blank. Use below docker-compose command to download images, create and start containers instances. The "-E" option allows to read all the newly created environment variables from the previous step.

All the password variables in docker-compose.yml file are read from below system environment variables. Replace the below shell variables with corresponding password values to be used by individual services. If no value is provided for the below password variables then their value is treated as blank. $ export POSTGRES_PASSWORD=$POSTGRES_PASSWORD $ export MONGO_INITDB_ROOT_PASSWORD=$MONGO_INITDB_ROOT_PASSWORD $ export CONFIG_SERVICE_PASSWORD=$CONFIG_SERVICE_PASSWORD $ export CONFIG_KEYSTORE_PASSWORD=$CONFIG_KEYSTORE_PASSWORD $ export CONFIG_KEY_PASSWORD=$CONFIG_KEY_PASSWORD $ export AUTH_SERVICE_PASSWORD=$AUTH_SERVICE_PASSWORD $ export FINANCE_SERVICE_PASSWORD=$FINANCE_SERVICE_PASSWORD $ export ANALYTICS_SERVICE_PASSWORD=$ANALYTICS_SERVICE_PASSWORD
Use below docker-compose command to download images, create and start containers instances. The "-E" option allows to read all the newly created environment variables from the previous step. $ sudo -E docker-compose up -d
The above docker-compose up -d command would create all the containers and start all the services parallelly in background. Since virtually all the services are dependent on few core services namely postgres-service, config-service, discovery-service and authorization-service, this would cause other services to fail and restart again until they establish successful connections with core services.
It is important to note that docker-compose detects changes in the environment variables compared to existing service instance running with different environment variables. On launching a new service which depends on an already existing service whose environment variables are altered, docker-compose would first trigger recreation of existing (dependent) service instance with the current system environment variables before creating the launched instance.
