Add log rotation and log size limits to the nerdctl.toml configuration file

[niroshea]

What is the problem you're trying to solve

When I run the container with the following command, it works fine.

nerdctl run --log-opt=max-size=100m --log-opt=max-file=5 -d nginx

But I can't specify the --log-opt option when I need to start multiple containers with the nerdctl compose command.

nerdctl compose --log-opt=max-size=100m --log-opt=max-file=5 -f docker-compose.yaml up -d

The error message is as follows: FATA[0000] unknown flag: --log-opt

Is it possible to add options such as log-opt.max-size log-opt.max-file to the nerdctl.toml configuration file so that nerdctl's logging management can take effect globally, avoiding the need to specify parameters on the command line each time?

HI @niroshea

The log can be configured in the compose file like: https://docs.docker.com/reference/compose-file/services/#logging

And the nerdctl needs to keep the compatibility with docker.

I tried to use this approach with a docker-compose file with the following contents

services:

  ...

  nginx:
    image: nginx
    container_name: nginx
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf
    restart: always
    network_mode: host
    logging:
      driver: json-file
      options:
        max-size: "200m"
        max-file: "3"
    ulimits:
      nproc: 65535
      nofile:
        soft: 32000
        hard: 40000
