Splunk® Enterprise

Installation Manual

Splunk Enterprise version 9.0 will no longer be supported as of June 14, 2024. See the Splunk Software Support Policy for details. For information about upgrading to a supported version, see How to upgrade Splunk Enterprise.

Deploy and run Splunk Enterprise inside a Docker container

Run Splunk Enterprise inside a Docker container to quickly deploy an instance and gain hands-on experience with Splunk software. The official repository containing Dockerfiles for building Splunk Enterprise and Universal Forwarder images can be found on GitHub for Splunk-Docker.

Container orchestration for Splunk Enterprise

For container orchestration, the Splunk Operator for Kubernetes on GitHub enables you to quickly and easily deploy Splunk Enterprise on your choice of private or public cloud provider. The operator simplifies scaling and management of Splunk Enterprise by automating workflows while implementing Kubernetes best practices.

See the splunk-operator documentation on GitHub for more information.

Containerized Splunk software prerequisites

The list of requirements for Docker and Splunk software is available in the Support Guidelines on the Splunk-Docker GitHub. The requirements include OS architecture, Docker version, and supported Splunk architectures.


Deploy Splunk Enterprise Docker containers

You can deploy Splunk Enterprise inside a Docker container by downloading and launching the required Splunk Enterprise image in Docker. The image is an executable package that includes everything you need to run Splunk Enterprise. For universal forwarder instructions, see the Universal Forwarder manual.

  1. From a shell prompt, run the following command to download the required Splunk Enterprise image to your local Docker image library.
    docker pull splunk/splunk:latest
    
  2. Run the downloaded Docker image.
    docker run -d -p 8000:8000 -e SPLUNK_START_ARGS='--accept-license' -e SPLUNK_PASSWORD='<password>' splunk/splunk:latest
    
    • The SPLUNK_PASSWORD='<password>' parameter sets the login password for the admin user. There are minimum requirements when setting passwords, which can change with different versions of Splunk Enterprise. To review the minimum password requirements, see Configure a Splunk password policy in Authentication.conf in the Securing the Splunk Platform manual.
    • The port definition -p <host_port>:<container_port> will expose a port used by the containerized application to the outside network by mapping it to port on the local host. In the example above, the SplunkWeb port 8000 is mapped to the host port 8000. If a host port is already occupied by another service, you can use the -p parameter to re-map a port to another open port on the host, example: -p 9000:8000. You can later verify the ports in use by running docker port <container_id>
  3. The output of the docker run command is a hash of numbers and letters that represents the container ID of your new Splunk Enterprise instance. Run the following command with the container ID to display the status of the container.
    docker ps -a -f id=<container_id>
    
    • To verify the container ID, run docker ps to review the container ID, status, and port mappings of all running containers.
  4. Open an web browser on the host and access SplunkWeb inside the container using the address:
    localhost:8000
    
  5. Log in to Splunk Enterprise inside the container using the username admin and the password you set when you ran the Docker image.

Administer Splunk Enterprise Docker containers

You can use the following Docker commands to manage containers.

  • To see a list of example commands and environment variables for running Splunk Enterprise in a container, run:
    docker run -it splunk/splunk help
    
  • To see a list of your running containers, run:
    docker ps
  • To stop your Splunk Enterprise container, run:
    docker container stop <container_id>
    
  • To restart a stopped container, run:
    docker container start <container_id>
    
  • To access a running Splunk Enterprise container to perform administrative tasks, such as modifying configuration files, run:
    docker exec -it <container_id> bash
