knime/knime-lts repository overview

⁠Introduction

Here you can find the Docker executor images made available by KNIME, which correspond to the <default> and <full> builds of KNIME executor.
The Docker image of the KNIME executor in the desired version needs to be referenced in order to create execution contexts⁠. Execution contexts provide dedicated execution resources with configured settings to run and deploy workflows on KNIME Business Hub.

LTS (Long-Term Support): production-quality releases every ~6 months, supported for 2 years with bug fixes and security updates. No new features during the support window.

We publish two images in total (by release line × build type):

• LTS — default (knime:r-<version>-<build>)
• LTS — full (knime-full:r-<version>-<build>)

⁠Image names and tags

Two different types of images are made available:

• knime: these images contain only the base extensions shipped with the specified version of KNIME executor. Use them as a base image for further customization.
• knime-full: these images instead contain all the extensions developed by KNIME

Each image then will contain a tag of the type: r-<version>-<build> where r stands for released, <version> is the version number of the executor and <build> is the incremental build number.

⁠STEP-BY-STEP: LTS images (default & full)

Use when you want 2-year support and fewer updates.

• Pick your LTS version (see release notes) and choose default vs full.
• Pull or reference the image:
  • docker pull knime:r--
  • docker pull knime-full:r--
• (Optional) Customize by extending the image.
• (Optional) Register in Hub via “Manage List of Executor Images”.
• Create/update execution contexts. Plan updates every 6 months with bug/security patches in between.

⁠Use the Executor Image in KNIME Hub

In order to create an execution context on KNIME Hub, that uses a specific Docker Image, follow the instructions on the KNIME documentation⁠.

⁠Customizing the Executor Image

In order to install additional extensions and features to the KNIME Executor image, you will need to first create a Dockerfile, build a Docker image from it, and finally make it available by pushing it to a registry. You can do this in two ways:

• Via a data application, provided by us
• Via a manual approach using docker

Please refer to the KNIME documentation⁠ for a detailed description and step-by-step instructions.

⁠Update the Executor Image

To update an execution context to a newer version of the Executor Image, follow the instructions on the KNIME documentation⁠.
