Splunk Docker Install

The Splunk Docker image supports the ability to dynamically install any Splunk-compliant app or add-on. These can be certified apps that are hosted through SplunkBase or they might be local apps you have developed yourself. App installation can be done a variety of ways: either through a file/directory volume-mounted inside the container,. To try Splunk latest features you have to install matched or higher version of Docker Client. If you are using docker machine, you can just ssh on just created machine $ docker-machine ssh docker-1.13.0-rc2. Skip verification for HTTP Event Collector endpoint availability-log-opt splunk-verify-connection=true false.

Before you install Splunk Connect for Docker, make sure your system meets the following minimum prerequisites: Docker Engine: Version 17.05 or later. If you plan to configure Splunk Connect for Docker via 'daemon.json', you must have the Docker Community Edition (Docker-ce) 18.03 equivalent or later installed. Download and install a Splunk Enterprise installation package; Download the Splunk Enterprise Docker image and run Splunk Enterprise inside a Docker container; Containerized Splunk Enterprise provides a simplified and consistent way for you to quickly get started with Splunk Enterprise and gain hands-on experience with the software. In this section, we will talk about setting up the Splunk Free edition on Docker. Note: This guide is intended to use in a local lab environment for testing purposes. The free Splunk version also has a limit on how much data it can index. You may want to get a license from Splunk if you plan to in.

This section aims to guide the user through the process of installing Wazuh and its multiple components. A brief explanation about each component and its capabilities can be found in the getting started section.

Install Wazuh server¶

It extends Splunk’s Machine Learning Toolkit with prebuilt Docker containers for TensorFlow 2.0, PyTorch and a collection of NLP libraries. Python expertise is required to create your own neural networks. Install Sensu Go. Deploy our official Docker container to get up and running in seconds. Docker.exe network create sensu docker.exe volume create sensu-backend. Production Install on Windows Server (Unofficial) Deploy Mattermost on Docker; Deploy Mattermost on Cloudron (Unofficial) Upgrading Mattermost Server with a Script; लाइट इनस्टॉल गाइड. Install Wazuh agents¶ The Wazuh Agent is a single, light-weight monitoring software that that runs on most operating systems and provides visibility into the security of that endpoint by collecting critical system and application records, inventory data and detecting potential anomalies. If using the TCP or UDP sinks install the following packages. TCP: Serilog.Sinks.Splunk.TCP UDP: Serilog.Sinks.Splunk.UDP To start using the Splunk Event Collector (Splunk 6.3 and above), logging can be setup as follows.

There are two different alternatives to deploy a Wazuh installation:

  • All-in-one: All the Wazuh components are installed in the same host. This type of deployment is appropriate for testing and small working environments. If you want to test Wazuh, you can download our ready-to-use OVA.

  • Distributed: Each component is installed in a separate host as a single-node or multi-node cluster. This type of deployment allows high availability and scalability of the product and is convenient for large working environments.

Note

Wazuh also offers the Wazuh Cloud, where all components are hosted on our PCI-DSS certified SaaS solution and maintained by our team. With the Wazuh cloud, no dedicated hardware is required and everything is ready to use. This service offers a highly flexible infrastructure to match your enterprise needs.

This installation guide will teach you how to install all Wazuh components: the Wazuh agent, the Wazuh manager and Elastic Stack. Alternatively, Wazuh can be installed with commercial options like Elastic Stack basic license or Splunk. To learn more about these options and other installation alternatives, visit the more installation alternatives section.

Install Wazuh agents¶

The Wazuh Agent is a single, light-weight monitoring software that that runs on most operating systems and provides visibility into the security of that endpoint by collecting critical system and application records, inventory data and detecting potential anomalies. To install a Wazuh agent, select your operating system and follow the installation steps:

Splunk Docker Install Centos

Requirements¶

Install Splunk On Docker

Splunk Docker Server.conf

The requirements section specifies the supported operating systems as well as the minimum recommended hardware specifications to guarantee the expected performance. Furthermore, information about the expected alerts per second depending on the different types of monitored endpoints can be found, allowing users to calculate the expected data storage needed for their environments.

Installing Splunk Apps and Add-ons

The Splunk Docker image supports the ability to dynamically install any Splunk-compliant app or add-on. These can be certified apps that are hosted through SplunkBase or they might be local apps you have developed yourself.

App installation can be done a variety of ways: either through a file/directory volume-mounted inside the container, or through an external URL for dynamic downloads. Nothing is required for the former, and the environment variable SPLUNK_APPS_URL supports the latter.

NOTE: Installation of Splunk Enterprise Security (ES) and Splunk IT Service Intelligence (ITSI) is currently not supported with this image. Please contact Splunk Services for more information on using these applications with Splunk Enterprise in a container.

Navigation

Volume-mount app directory

If you have a local directory that follows the proper Splunk apps model, you can mount this entire path to the container at runtime.

For instance, take the following app splunk_app_example:

We can bind-mount this upon container start and use it as a regular Splunk app:

You should be able to view the splunk_app_example in SplunkWeb after the container successfully finished provisioning.

Download via URL

Installing Splunk On Docker

In most cases, you’re likely hosting the app as a tar file somewhere accessible in your network. This decouples the need for Splunk apps and configuration files to exist locally on a node, which enables Splunk to run in a container orchestration environment.

SplunkBase apps

Splunk Docker Install

Please refer to this docker-compose.yml file for how to download SplunkBase apps with authentication:

Self-hosted apps

Please refer to this docker-compose.yml file for how to download any app hosted at an arbitrary location:

Apps on filesystem

If you build your own image on top of the splunk/splunk or splunk/universalforwarder image, it’s possible you may embed a tar file of an app inside. Or, you can go with the bind-mount volume approach and inject a tar file on container run time. In either case, it’s still possible to install an app from this file on the container’s filesystem with the following.

Please refer to this docker-compose.yml file for how to install an app in the container’s filesystem:

Multiple apps

As one would expect, Splunk can and should support downloading any combination or series of apps. This can be incredibly useful when cross-referencing data from various sources.

The SPLUNK_APPS_URL supports multiple apps, as long as they are comma-separated. Refer to this docker-compose.yml file for how to install multiple apps:

Apps in distributed environments

This docker image also deploys apps when running Splunk in distributed environments. There are, however, special cases and instructions for how apps get deployed in these scenarios.

In the case of multiple search heads (no clustering) and multiple indexers (no clustering), you will explicitly need to tell each container what apps to install by defining a SPLUNK_APPS_URL for each role. See the example below and note the different apps used for search heads and indexers:

Splunk Docker Install App

In the case of search head clusters, you will explicitly need to tell the splunk_deployer what apps to install by defining a SPLUNK_APPS_URL for that particular role. The deployer will manage the distribution of apps to each of the search head cluster members (search heads). See the example below and note the different apps used for search heads and indexers:

Install Splunk On Docker

In the case of indexer clusters, you will explicitly need to tell the splunk_cluster_master what apps to install by defining a SPLUNK_APPS_URL for that particular role. The cluster master will manage the distribution of apps to each of the indexer cluster members (indexers). See the example below and note the different apps used for search heads and indexers:
