Welcome to the official Splunk repository of Dockerfiles for building Splunk Enterprise and Splunk Universal Forwarder images for containerized deployments.
⚠️ DEPRECATION NOTICE
We are no longer releasing Debian images on Docker Hub as of May 2021 (Splunk Enterprise v8.2.0+). Red Hat images will continue to be published.
Splunk Enterprise is a platform for operational intelligence. Our software lets you collect, analyze, and act upon the untapped value of big data that your technology infrastructure, security systems, and business applications generate. It gives you insights to drive operational performance and business results.
See Splunk Products for more information about the features and capabilities of Splunk products and how you can bring them into your organization.
This is the official source code repository for building Docker images of Splunk Enterprise and Splunk Universal Forwarder. By introducing containerization, we can marry the ideals of infrastructure-as-code and declarative directives to manage and run Splunk Enterprise.
The provisioning of these containers is handled by the Splunk-Ansible project. Refer to the Splunk-Ansible documentation and the Ansible User Guide for more details.
Start a single containerized instance of Splunk Enterprise with the command below, replacing <password> with a password string that conforms to the Splunk Enterprise password requirements.
$ docker run -p 8000:8000 -e "SPLUNK_PASSWORD=<password>" \
-e "SPLUNK_START_ARGS=--accept-license" \
-it --name so1 splunk/splunk:latestThis command does the following:
- Starts a Docker container using the
splunk/splunk:latestimage. - Names the container as
so1. - Exposes a port mapping from the host's
8000port to the container's8000port - Specifies a custom
SPLUNK_PASSWORD. - Accepts the license agreement with
SPLUNK_START_ARGS=--accept-license. This agreement must be explicitly accepted on every container or Splunk Enterprise doesn't start.
After the container starts up, you can access Splunk Web at http://localhost:8000 with admin:<password>.
To view the logs from the container created above, run:
$ docker logs -f so1To enter the container and run Splunk CLI commands, run:
# Defaults to the user "ansible"
docker exec -it so1 /bin/bash
# Run shell as the user "splunk"
docker exec -u splunk -it so1 bashTo enable TCP 10514 for listening, run:
docker exec -u splunk so1 /opt/splunk/bin/splunk add tcp 10514 \
-sourcetype syslog -resolvehost true \
-auth "admin:${SPLUNK_PASSWORD}"To install an app, run:
docker exec -u splunk so1 /opt/splunk/bin/splunk install \
/path/to/app.tar -auth "admin:${SPLUNK_PASSWORD}"
# Alternatively, apps can be installed at Docker run-time
docker run -e SPLUNK_APPS_URL=http://web/app.tgz ...See Deploy and run Splunk Enterprise inside a Docker container for more information.
