Installing a Groundplex on a Docker Container

In this article

Overview

SnapLogic support for the Groundplex (also known as an on-premise Snaplex) on a Docker container empowers customers to optimize IT infrastructure costs while benefiting from containerized technology.

The latest SnapLogic Docker image is based on AlmaLinux. Since we host the Docker image in the Docker Hub, you need to perform a pull operation to retrieve the latest Docker image.

For Docker-based Snaplex installation, updating the Docker images updates the JRE version.

We recommend installing the latest JRE 11 version available at Latest Releases | Adoptium.

If you are running with 11.0.10 onwards, endpoint connections to TLS 1.0 and 1.1 are disabled by default. We recommend that you update the endpoint to support TLS 1.2 or higher, for security.

Prerequisites

Installing Groundplex in a Docker Container

  1. Retrieve the latest Docker image from Docker Hub using the following pull command:

    docker pull registry.hub.docker.com/snaplogic/snaplex:main-<build number>>
  2. In SnapLogic Manager, navigate to your target Groundplex instance and click it to display the Update dialog.

  3. In the Downloads tab, click image-20240710-122356.png next to Configuration option to download the slpropz file for your Groundplex node.

After downloading the configuration file, you are ready to launch your Groundplex as a Docker container.

Create a Docker Image for a Groundplex

You can now create a Docker image from Linux/RPM, available in the Downloads tab as a more secure alternative using the Docker file. The Docket file lists all the commands required to build the Docker image.

Prerequisite

Before launching the Docker build command ensure the following:

  • The SnapLogic war file is in the proper location (“/tmp/snaplogic-sidekick-*.rpm”)

  • The nomenclature includes sidekick.

  1. To execute the Docker build with the Docker File, use the command: docker build - < Dockerfile>

  2. The docker build command builds the Docker images from a Docker file and a context, which is the set of files located in the specified PATH or URL. Learn more at Docker File.

Running a Snaplex Node from Docker

To run the Snaplex node from Docker:

  1. Create a local directory <Configuration_Path>/etc, and add the slpropz configuration file to the folder, ensuring that the file extension is .slpropz.

  2. Create an empty log folder <Log_Path>/log. The JCC logs are written to this directory.

  3. Enter the following command to create and run the latest version of the Docker container image:

    docker run -itd -h <Container_Host_Name> \ -p 8090:8090 -p 8081:8081 \ -v <CONFIG_PATH>/etc:/opt/snaplogic/etc \ -v <LOG_PATH>/log:/opt/snaplogic/run/log \ snaplogic/snaplex:latest

    where:

    • -p enables port mapping so that you can use the local dashboard and FeedMaster. You can also use other Docker networks if required.

    • -v enables you to specify the Docker volume to use. Store the <Snaplex_Name>.slpropz in the /opt/snaplogic/etc directory.
