Starting from the 2.2.0 release we started publishing three different flavours of the docker image.
:2.2.8tag if you only need GZip output format
:2.2.8-lzotag if you also need LZO output format
:2.2.8-distrolesstag for an lightweight alternative to `:2.2.0`
docker pull snowplow/snowplow-s3-loader:2.2.8
docker pull snowplow/snowplow-s3-loader:2.2.8-lzo
docker pull snowplow/snowplow-s3-loader:2.2.8-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.
