Docker

Dependencies

The Dockerfile in the main repo is based on a docker image built with Dockerfile_Deps.

~/ironapi/ironapi-gw/etc[master]$ docker build -t ironapi/ironapi-gw-deps .

Copy vs Mount

When the main docker image is built,

~/ironapi/ironapi-gw[master]$ docker build -t ironapi/ironapi-gw .

it takes a copy of the current directory to be mounted in /app on startup.

docker run -t -p 3000:3000 --name ironapigw

Beware: any code changes after building the image will not be available when you run the image! So, db.conf needs to be written before building the image, or the current directory can be mounted (this overrides the copy directive in the Dockerfile):

docker run -t -p 3000:3000 --name ironapigw --mount type=bind,source="$(pwd)",target=/app ironapi-gw

Logging

Docker redirects anything written to STDOUT or STDERR to the configured log driver. To change it from the default "json-file" to syslog, either configure it for the entire host system:

root@ninne:/etc/docker# more daemon.json 
{
    "log-driver" : "syslog"
}

or set it a run time:

`docker run -t --log-driver syslog`

Them messages end up in the syslog tail -f /var/log/syslog

All scripts use the same, which currently sends everything to STDOUT as well as a log file. Note the -t option - it allocates a pseudo-TTY, which also gets us the catalyst access log on STDERR.
