A minimal Docker image for running the tabula-java from a Docker container. Based on java:openjdk-8-jre-alpine.
You can mount a PDF file available at /full/path/to/my/file.pdf to the docker container by using the -v option to the docker run command:
$ docker run --rm -v /full/path/to/my/file.pdf:/data.pdf sseemayer/tabula-java [tabula options] /data.pdf > output.csv
To get tabula help:
$ docker run --rm sseemayer/tabula-java --help
usage: tabula [-a <AREA>] [-c <COLUMNS>] [-d] [-f <FORMAT>] [-g] [-h] [-i]
[-n] [-o <OUTFILE>] [-p <PAGES>] [-r] [-s <PASSWORD>] [-u] [-v]
Tabula helps you extract tables from PDFs
-a,--area <AREA> Portion of the page to analyze
(top,left,bottom,right). Example: --area
269.875,12.75,790.5,561. Default is entire
page

--columns 10.1,20.2,30.3
-d,--debug Print detected table areas instead of
processing.
-f,--format <FORMAT> Output format: (CSV,TSV,JSON). Default: CSV
-g,--guess Guess the portion of the page to analyze per
page.
-h,--help Print this help text.
-i,--silent Suppress all stderr output.
-n,--no-spreadsheet Force PDF not to be extracted using
spreadsheet-style extraction (if there are
ruling lines separating each cell, as in a PDF
of an Excel spreadsheet)
-o,--outfile <OUTFILE> Write output to <file> instead of STDOUT.
Default: -
-p,--pages <PAGES> Comma separated list of ranges, or all.
Examples: --pages 1-3,5-7, --pages 3 or

spreadsheet-style extraction (if there are
ruling lines separating each cell, as in a PDF
of an Excel spreadsheet)
