URL: https://github.com/apache/zeppelin/pull/4178
### What is this PR for?
Currently, users can build a smaller docker image of zeppelin interpreter by
modifying the Dockerfile in `scripts/docker/zeppelin-interpreter`. But I think
a more ideal way is that user can use a shell script to build the docker image
(something like `docker-image-tool.sh` in Apache Spark) and specify the
interpreters they want.
Example usage:
```
Usage: ./Dockerfile_gen.sh [options] [command]
This script outputs a Dockerfile for building the zeppelin image that
contains some specific interpreters.
Options:
-i interpreter (Optional) A comma-separated list of interpreter
directory names (under /path/to/zeppelin/interpreter/)
that need to be add into the docker image.
By default, it will add the spark interpreter.
-c conda yaml file (Optional) Specify the conda yaml file that manages
python and R packages. By default, it will not install
python and R packages through conda.
-v zeppelin version (Optional) Specify the version of zeppelin. By
default, the version is "0.9.0".
Examples:
- Output the Dockerfile for building the zeppelin image that contains
spark and python interpreter.
./Dockerfile_gen.sh -i spark,python
- Output the Dockerfile for building the zeppelin image that contains
spark and python interpreter and specify the
conda yaml file "python3.yaml"
./Dockerfile_gen.sh -i spark,python -c python3.yaml
```
Example generated Dockerfile:
