Apache Atlas Docker image

This Apache Atlas is built from the 2.0.0-release source tarball and patched to be run in a Docker container.

Atlas is built with embedded HBase + Solr and it is pre-initialized (atlas_start.py -setup), so you can run Artas after image download without additional steps.

If you want to use external Atlas backends, set them up according to the documentation.

Basic usage

1. Pull the image:

docker pull sburn/apache-atlas

2. Start Apache Atlas in a container exposing Web-UI port 21000:

docker run --detach \
    -p 21000:21000 \
    --name atlas \
    sburn/apache-atlas \
    /opt/apache-atlas-2.0.0/bin/atlas_start.py

Please, take into account that at fist run Atlas initialize internal schemas and first startup may take up to 10 mins depending on host machine performance.

Usage options

Gracefully stop Atlas:

docker exec -ti atlas /opt/apache-atlas-2.0.0/bin/atlas_stop.py

Check Atlas startup script output:

docker logs -f atlas 

Check interactively Atlas application.log:

docker exec -it atlas tail -f /opt/apache-atlas-2.0.0/logs/application.log

Start Atlas overriding settings by environment variables (to support large number of metadata objects for example):

docker run --detach \
    -e "ATLAS_SERVER_OPTS=-server -XX:SoftRefLRUPolicyMSPerMB=0 \
    -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC \
    -XX:+CMSParallelRemarkEnabled -XX:+PrintTenuringDistribution \
    -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=dumps/atlas_server.hprof \
    -Xloggc:logs/gc-worker.log -verbose:gc -XX:+UseGCLogFileRotation \
    -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=1m -XX:+PrintGCDetails \
    -XX:+PrintHeapAtGC -XX:+PrintGCTimeStamps" \
    -p 21000:21000 \
    --name atlas \
    sburn/apache-atlas \
    /opt/apache-atlas-2.0.0/bin/atlas_start.py

Expose logs directory on the host to view them directly:

docker run --detach \
    -v ${PWD}/atlas-logs:/opt/apache-atlas-2.0.0/logs \
    -p 21000:21000 \
    --name atlas \
    sburn/apache-atlas \
    /opt/apache-atlas-2.0.0/bin/atlas_start.py

Expose conf directory on the host to edit configuration files directly:

docker run --detach \
    -v ${PWD}/pre-conf:/opt/apache-atlas-2.0.0/conf \
    -p 21000:21000 \
    --name atlas \
    sburn/apache-atlas \
    /opt/apache-atlas-2.0.0/bin/atlas_start.py
