2.2.x Upgrade Guide

Starting from the 2.2.0 release we started publishing three different flavours of the docker image.

  • Pull the :2.2.9 tag if you only need GZip output format

  • Pull the :2.2.9-lzo tag if you also need LZO output format

  • Pull the :2.2.9-distroless tag for an lightweight alternative to `:2.2.0` 

docker pull snowplow/snowplow-s3-loader:2.2.9
docker pull snowplow/snowplow-s3-loader:2.2.9-lzo
docker pull snowplow/snowplow-s3-loader:2.2.9-distroless

We removed LZO support from the standard image, because it means we can more easily eliminate security vulnerabilities that are brought in from a dependency on hadoop version 2.

The "distroless" docker image is built from a more lightweight base image. It provides some security advantages, because it carries only the minimal files and executables needed for the loader to run.
