docker compose logging is not working with syslog option

问题

I have a docker-compose configuration like this:

version: '3'
services:
  worker:
    image: // image
    logging:
      driver: syslog
      options:
        syslog-address: "udp://XXX.papertrailapp.com:XXXX"
        tag: "{{.Name}}/{{.ID}}"

When I deploy this to digital ocean & ubuntu I can successfully run the docker-compose up command like so:

docker-compose -f docker-compose.yml up

When that command runs I can see this output

worker_2_844fc7675414 | WARNING: no logs are available with the 'syslog' log driver
worker_1_5c91a3426046 | WARNING: no logs are available with the 'syslog' log driver

It appears that 'syslog' is correctly configured for the docker-compose to run, but that perhaps the 'syslog' driver is not available?

All the instructions I can find for using syslog with docker refer to docker run commands, but how can I get syslog working with docker-compose?

回答1:

This does in fact work. I erroneously had the papertrail details misconfigured so I was not seeing the logs.
