@Russ Hi, I have reduced the layering and now at 292MB it's only a more reasonable 111MB bigger than the base Node image.

FROM node:current-buster-slim

ARG DEBIAN_FRONTEND=noninteractive
RUN BUILD_DEPS=" \
        wget \
        npm" \
        && apt-get -y update && apt-get -y upgrade \
        && apt-get -y install ${BUILD_DEPS} \
        && wget -q https://s3.amazonaws.com/triggercmdagents/triggercmdagent_1.0.1_all.deb \
        && apt-get -y install ./triggercmdagent_1.0.1_all.deb && rm triggercmdagent_1.0.1_all.deb \
        && apt-get -y remove ${BUILD_DEPS} && apt-get -y autoremove

CMD node /usr/lib/triggercmdagent/resources/app/src/agent.js --console

I'm using this to run a script which takes the dynamic IP address from my phone and opens a /24 or /23 address range in the Google Cloud firewall (using a restricted API account) for one hour, so I can connect to my bastion host when tethering my laptop to my phone's internet connection (the IP address keeps changing, hence the IP range). I have an Alexa app on my phone called Reverb which runs when long-pressing one of the main buttons. I'll do the same for AWS and make a blog post about it.

I'm assuming npm is not needed when running triggercmd? I've not got around to adding the other stuff yet.

Cheers!

Duh, I wasn't using the GUI-less version of the agent. Correcting that and removing npm has reduced the size to 570MB, which is much better, but still rather large.

FROM node:current-buster-slim

ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get -y update && apt-get -y upgrade
RUN apt-get -y install wget npm
RUN wget -q https://s3.amazonaws.com/triggercmdagents/triggercmdagent_1.0.1_all.deb
RUN apt-get -y install ./triggercmdagent_1.0.1_all.deb && rm triggercmdagent_1.0.1_all.deb
RUN apt-get -y remove npm wget && apt-get -y autoremove

CMD node /usr/lib/triggercmdagent/resources/app/src/agent.js --console

I'm pleased with the solution triggercmd provides me and I want to package it up in a Docker container for security and convenience, along with some associated software I am using it with.

I have been intending to make an image compiling triggercmdagent using Alpine Linux as a base, to make it as tiny as possible, but because the resulting image is so many times larger than even a full OS container, this seems pointless. At 1GB, it's the largest docker container I am running, when I would have expected it to be one of the smallest.

I know node.js itself is pretty large, but even starting with a minimal base Debian image, a large number of libraries get installed, along with a lot of things that seem irrelevant. Can any of this be removed?

This is the relevant parts of the current draft of the Dockerfile:

FROM node:current-buster-slim

ARG DEBIAN_FRONTEND=noninteractive
RUN apt-get -y update && apt-get -y upgrade
RUN apt-get install -y apt-utils wget
RUN wget -q https://s3.amazonaws.com/triggercmdagents/triggercmdagent_1.0.1_amd64.deb
RUN apt-get install -y ./triggercmdagent_1.0.1_amd64.deb && rm triggercmdagent_1.0.1_amd64.deb
RUN apt-get autoremove

CMD node /usr/lib/triggercmdagent/resources/app/src/agent.js --console

And these are all the triggercmdagent dependencies which get installed:

Hunspell and aspell dictionaries, X11, VLC and GUI stuff, etc... Is it possible to strip this down?

Thanks.

Thanks. I was looking around in the forum for some reason.

Still feeling a bit lost here, possibly because I'm not using the GUI. I have been looking, but how do I make new triggers now (and delete some default triggers)? I would like to run some bash scripts by asking Alexa.

Also, I do not seem to be getting reply notifications from this forum. I think I have everything set correctly and this conversation is set as Watched.

Thanks. This is working for me as far as inputting the API token, as I have forgotten where it is. I remember seeing it earlier. Where is it again?

I would like to use this on a headless CentOS server, but there is only a .deb file for this and not an .rpm.

Is there anything I could do?

Thanks.
