Manually installing FusionReactor requires you to directly place the FusionReactor installation files and configure the JVM arguments on your application servers.
Step 1: Create a directory structure for FusionReactor and download the files:
FusionReactor JAR
Debugger Native Library
Step 2: Stop your application server
Step 3: Add additional JVM arguments to your application server configuration
-
Add a Java agent path (-javaagent argument) pointing to the fusionreactor.jar file.
-
The Debug native library path (-agentpath argument) needs to be pointing to the debug library.
Step 4: Restart your application server

Step 1: Start with your base image
Step 2: Create a FusionReactor directory in the/opt directory
Step 3: Add the fusionreactor.jar file to the FusionReactor instance directory
ADD https://download.fusionreactor.io/FR/Latest/fusionreactor.jar /opt/fusionreactor/instance/{your instance name}
Step 4: Add the debug library file (libfrjvmti_x64.so) to the FusionReactor instance directory
ADD https://download.fusionreactor.io/FR/Latest/libfrjvmti_x64.so /opt/fusionreactor/instance/{your instance name}
Step 5: Set the JAVA_OPTS environment variable to include FusionReactor in the JVM arguments
ENV JAVA_OPTS="-javaagent:/opt/fusionreactor/instance/{your instance name}/fusionreactor.jar=name=tomcat,address=8088 -agentpath:/opt/fusionreactor/instance/{your instance name}/libfrjvmti_x64.so"
Your Dockerfile should now be set up to create a Docker image with FusionReactor integrated into your chosen instance. Make sure to replace {your image} with the actual base image you intend to use and {your instance name} with your instance (eg. Tomcat) and look at our fusionreactor-docker GitHub repository for other example Dockerfiles.

Step 1: Prepare the API key
Before running your application in Docker, obtain an API key from the service or application you are working with. This API key is essential for authentication and configuration.
Step 2: Determine the environment variables
Determine which environment variables are required for your specific service or application. These environment variables are used to configure and customize the behavior of the service when running in Docker.
Step 3: Run the Docker container
docker run --env api_key=<your_api_key> --env mysql_connection_string=root:my-secret-pw@(mysql:3306)/ intergral/observability-agent:latest
