Docker

Manage Docker settings: update docker images, set global resource limits for docker, etc.

Images

Uses Cup 🥤 to check for image updates and displays them on OpenPanel > Containers > Image Updates

Check image updates for specific user:

opencli docker-images <USERNAME>

Example:

root@test:/usr/local/opencli# opencli docker-images s70nesto

Running Cup in context: s70nesto
Output for user s70nesto saved to /home/s70nesto/docker-data/cup/cup.json

Check image updates for all users:

opencli docker-images --all

logs

View logs sizes for user and system containers.

# opencli docker-logs

Usage: opencli docker-logs [options]

Options:
  <USERNAME>                                    Display log sizes for specified user.
  --system                                      Display log sizes just for system containers.
  --users                                       Display log sizes just for user containers.
  --all                                         Display log sizes for all user and system containers.

lazydocker (DEPRECATED)

To manage system containers *(run as root user):

opencli docker

To manage user containers:

opencli docker <USERNAME>

Collect Stats

To collect docker resource usage information (cpu, ram, i/o) for all users:

opencli docker-collect_stats

Limits

Set global docker limits (storage, ram and cpu) for all system containers.

opencli docker-limits [--apply | --read]

To view current limits:

opencli docker-limits --read

Example:

root@stefan:~# opencli docker-limits --read
[DOCKER]
max_ram=90
max_cpu=95
max_disk=114

CPU and RAM limit

To apply new limits for CPU % and RAM %:

opencli docker-limits --apply

Storage (disk) limit

To increase storage (disk) allocated to Docker, pass the size in GB:

opencli docker-limits --apply 100

Usage Stats Cleanup

Rotate resource usage logs for all users according to the resource_usage_retention setting.

opencli docker-usage_stats_cleanup
