ASF GitHub Bot commented on METRON-1650:
----------------------------------------
Github user jameslamb commented on the issue:
https://github.com/apache/metron/pull/1091
I broke this into two steps (was previously one):
```
# Install Software Collections repo (needs to be done in separate command) \
+ && yum install -y \
+ centos-release-scl \
+ # newer cpp 11 support required for building node modules \
+ && yum install -y \
```
because the other deps installed need `scl` repository to be registered
with `yum`
> Packaging docker containers are too large

> Key: METRON-1650
> URL: https://issues.apache.org/jira/browse/METRON-1650
> Project: Metron
> Issue Type: Improvement
> Reporter: James Lamb
> Priority: Minor
>
> I have been looking through the project source code, and found that the
> packaging docker containers are bigger than they need to be.
> The containers' size could be cut substantially by:
> * Grouping as many commands as possible into as few RUN stages as possible
> * Taking advantage of `yum clean` and `apt-get clean`
> * Removing artifacts pulled with `wget`
> * Removing unused libraries or libraries only needed at build time (like
> `tar` and `wget`)
> I am creating this issue but will soon submit a PR to address it.
> Thank you for considering my proposal!
