Hi guys!
I'm currently building a docker container with splunk/universalforwarder:7.0.0-monitor-k8s-logs as base image. During my docker build i install my own node.js and want to add my own scriptedinput scripts.
my eventhub folder:
/bin/myscript
/bin/package.json
Dockerfile:
FROM splunk/universalforwarder:7.0.0-monitor-k8s-logs
RUN apt-get update \
&& apt-get install curl -y \
&& curl -sL https://deb.nodesource.com/setup_8.x | bash \
&& sudo apt-get install -y nodejs
COPY eventhub /opt/splunk/etc/apps/eventhub/
WORKDIR /opt/splunk/etc/apps/eventhub/bin/
RUN npm i --production && ls -al <==
ls -al gives me that all are successfully created:
myscript
node_modules
package.json
package.json.lock
However running my new image, the node_modules folder and package.json.lock is missing. After doing a manual npm install in the container everything is working.
Copying the files to /opt/splunk/ and doing the npm install there and not to /opt/splunk/etc the files are there.
I think it has something to do with the base image volumes of /opt/splunk/etc and /opt/splunk/etc see: https://github.com/splunk/docker-splunk/blob/master/enterprise/Dockerfile. But i cant't figure out what...I don't run splunk when running the image so i don't know how the volumes getting manipulated and also why only the npm install files getting deleted.
Thanks for your help!
