How to configure Runtime Connectivity​

  1. Find Connected Services in component detail and click on the Connection properties button
    • The displayed environment variables will be set during deployment depending on which service instance you choose to use
  2. Modify your project's deployment configuration to use the environment variables from the previous step for establishing a connection with the service
    • The format of your configuration files depend on your tech stack
    • For example, for the PostgreSQL from the images below, you could define the following connection string: "Host=${POSTGRESQL_HOST};Port=${POSTGRESQL_PORT};Database=${POSTGRESQL_DATABASE_NAME};User Id=${POSTGRESQL_USERNAME};Password=${POSTGRESQL_PASSWORD}"
info

Select a specific service instance in preview or manually created deployment configuration and CodeNow will automatically set the environment variables, so that your component will be connected to the chosen service.
