----------------------------------------
Summary: Reduce image size
Key: RANGER-5160
URL: https://issues.apache.org/jira/browse/RANGER-5160
Project: Ranger
Issue Type: Sub-task
Components: docker
Reporter: Attila Doroszlai
Assignee: Attila Doroszlai
Docker image size is affected by content from each layer. Thus, build steps
like the following inflate image size:
{code}
COPY tarball
RUN extract tarball
{code}
{code}
COPY contents dir/
RUN chmod/chown ... dir
{code}
These can be improved by:
- using {{ADD}}, which can extract tarball, or pre-extracting the tarball
locally
- specifying chmod and chown for {{COPY}}
