Closed Axelfoley85 closed 4 years ago

Axelfoley85 commented 4 years ago

I cant reproduce the build. I also changed to python 3.4 exactly like in the Dockerfile in your public docker registry

=== Dockerfile ===

FROM python:3.4-slim

RUN pip install snmpsim

RUN adduser --system snmpsim

ADD data /usr/local/snmpsim/data

EXPOSE 161/udp

CMD snmpsimd.py --agent-udpv4-endpoint=0.0.0.0:161 --process-user=snmpsim --process-group=nogroup $EXTRA_FLAGS

=== Build+Run ===

IMAGE_NAME=snmpsim
CONTAINER_NAME=snmpsim
docker build \
    -t ${IMAGE_NAME} \
    .
docker rm -f $(docker ps -a | grep snmp | awk '{print $1}')
docker run \
    --name ${CONTAINER_NAME} \
    -v "$(pwd)/data:/usr/local/snmpsim/data" \
        -p 161:161/udp \
    ${IMAGE_NAME}

=== Log of Running dockerfile / snmpsim.py ===

=== Running snmpwalk === will lead to the above error message snmpwalk -v2c -c demo $(docker inspect snmpsim | grep IPA | tail -n1 | cut -d\" -f 4) .

=== Additional info === The missing file actually exists in /tmp/snmp and is not empty. I also understand that you are not responsible for snmpsim.py. Though I would like to be able to reproduce the build of the image which doesn't work for me here. When I pull the image it works fine.

=== BUILD ON === ubuntu 18.04 Docker version 19.03.12, build 48a66213fe

Using unreleased version of snmpsim from master solved this problem.

Replacing RUN pip install snmpsim with RUN pip install https://github.com/etingof/snmpsim/archive/master.zip in the Dockerfile works for this issue.
