Run the TRIGGERcmd linux agent in a Docker container

[Russ]

Docker provides a quick and easy way to package and run Linux software. This also works on Windows if you run Docker on Windows.

Here's how to build and run a Docker container that runs the TRIGGERcmd agent:

Create a text file called Dockerfile with these contents:

FROM ubuntu

ENV DEBIAN_FRONTEND=noninteractive 
RUN apt-get -y update && apt-get -y upgrade
RUN apt install -y nodejs npm wget
RUN wget https://s3.amazonaws.com/triggercmdagents/triggercmdagent_1.0.1_amd64.deb
RUN apt install -y ./triggercmdagent_1.0.1_amd64.deb

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

To build the container image, cd to the directory where you put the Dockerfile file, then run this command:

docker build . --tag=triggercmdagent

To see your new Docker image in your local Docker cache, run this command:

docker images

To run your new image on Linux and use /tmp as your TRIGGERcmd data folder, run:

docker run -it -v /tmp:/root/.TRIGGERcmdData triggercmdagent

To run your new image on Windows and use c:\mydir as your TRIGGERcmd data folder, run:

docker run -it -v c:\mydir:/root/.TRIGGERcmdData triggercmdagent

When you run it, you'll see it prompt for your token (from the Instructions page):

Run installdaemon.sh to install the triggercmdagent daemon so it runs during boot
Daemon install: false
No token exists.  Login to request one.
prompt: token:
