If you are running the application in a non-Kubernetes environment (using docker run for example), set the agent environment variables in the Dockerfile.

For example:

ENV APPDYNAMICS_AGENT_APPLICATION_NAME=<value>
ENV APPDYNAMICS_AGENT_TIER_NAME=<value>
ENV APPDYNAMICS_AGENT_ACCOUNT_NAME=<value>
ENV APPDYNAMICS_AGENT_ACCOUNT_ACCESS_KEY=<value>
ENV APPDYNAMICS_CONTROLLER_HOST_NAME=<value>
ENV APPDYNAMICS_CONTROLLER_PORT=<value>
ENV APPDYNAMICS_CONTROLLER_SSL_ENABLED=<value>
ENV APPDYNAMICS_JAVA_AGENT_REUSE_NODE_NAME=true
ENV APPDYNAMICS_JAVA_AGENT_REUSE_NODE_NAME_PREFIX=<value>

For Kubernetes applications, omit these environment variables from the Dockerfile and set them using ConfigMaps and Secrets as described in Best Practices to Configure Agents in Kubernetes.

The reuse node name and prefix environment variables are required to support unique naming for multiple container instances for the same application image. See Reuse Node Name.
