Copyright Barbarians 2018. https://barbarians.io
This repository contains a GPL-free (mostly derived from BSD) base image for Docker containers. The biggest limitation at the moment is Java - Apache Harmony ceased operations in 2010 leaving a void that has not yet been filled. Google went a different path but still use Apache Harmony extensively for its Java Class Library.
As such we bake in Apache Harmony but it is more useful to remotely fetch an open-jdk kit once the image is deployed. You can do this with the onboard Python.
The image includes:
- mksh
- vim
- libffi
- zlib
- sabotage linux kernel headers
- python2.7
- heirloom UNIX tools (SCO & Sun donations)
- openssl
- Apache Harmony
- cawf - alternative to nroff
- musl libc as a replacement for glibc
Additionally the image statically links ncurses, which while part of the GNU toolset, is MIT licensed.
Note that the tools expr and bc are removed from the image as they're GPL.
This image is a first release and will improve over time.
This image is a base image that you can use to build upon. If you want to inspect it, have a look at our github repo.
If you just want to try it out, run these commands:
docker run -it dockerbarbarians/gpl-free-base-image /bin/mksh
You will be dropped into a Mir Korn shell (mksh) where you can try out, for example, the bundled python runtime at /opt/python27.
Since this image does not include GNU glibc, you will need to compile your application using musl-gcc linked to the musl libc implementation. Alternatively you could bring your own glibc, or download it from within the container.
Barbarians offer the world's best cloud-native data system founded on Apache Hadoop® - the Barbarian data system.
The Barbarian Data System is an in-memory, parallel, distributed (MPP) data warehousing engine designed to be deployed to Kubernetes clusters, offering Apache Hive for powerful and flexible SQL based analytics. Barbarian includes an integrated in-memory filesystem and can run in three modes of operation.
- As an in-memory, standalone data warehousing system
- As a data warehousing system backed by an external storage system like Amazon S3
- In a hybrid mode, where primary storage is the external storage system with common paths mounted to the in-memory filesystem
Barbarian includes compelling features including Apache Hive LLAP and Tez, with transactional tables enabled by default.
Barbarian's integrated Ignite in-memory distributed parallel filesystem is resilient to node failure with replication enabled by default.
Barbarian has no single points of failure.
Barbarian is offered with the Apache v2.0 software license.
Barbarian can be deployed to your Kubernetes cluster with just two commands:
helm repo add barbarians http://charts.barbarians.io/barbarian
helm install barbarians/barbarian
