Running configuration generator as a Docker container

[diegomsamana]

I'm trying to run the configurator generator as a Docker container, and I'm able to build it. Unfortunately, I do not understand the proper syntax to pass the "generator.yml" and mibs folder to the container. The readme for the generator states:

"If you would like to run the generator in docker to generate your snmp.yml config run the following commands.

The Docker image expects a directory containing the generator.yml and a directory called mibs that contains all MIBs you wish to use."

How does it expect the directories? I can map a volume, but how do I make sure that the generator command receives it properly? What are the proper arguments for this?

From the Makefile:

docker run --rm -v "${PWD}:/opt$(DOCKER_VOL_OPTS)" "$(DOCKER_REPO)/$(DOCKER_IMAGE_NAME):$(SANITIZED_DOCKER_IMAGE_TAG)" --no-fail-on-parse-errors generate

you can either change the volume mount to another dir, or use the cmdline flags -m (mibdir) and -g (generator-path to yml)

Thank you so much for the help!

If anyone is looking for this. You have to make sure to bind mount the location where you have your "mibs" folder and your "generator.yml" folder to the /opt folder inside the container. The "snmp.yml" output will end up in the folder you bound. This is an example of my Dockerfile:

services:  
  snmp_configgen:
    build: ./configgen
    restart: on-failure:3
    deploy:
      mode: replicated
      replicas: 1
    volumes:
      - ./config/snmp/generator-samm.yml:/opt/generator.yml #mapped my local file to the generator yml
      - ./config/snmp/samm-mibs:/opt/mibs #mapped my mibs folder to the "mibs" folder in /opt in the container
      - ./config/snmp:/opt # "snmp.yml"file will be generated in this folder.
    command: generate --no-fail-on-parse-errors`
```
