Docker Loki Driver ARM64

[feniarus]

Is your feature request related to a problem? Please describe. I tried installing the Loki Docker Driver but it doesn't work because it is for AMD64 only at the moment.

Describe the solution you'd like Adding support for ARM64 and ARM/v7 Can be done by cross compiling even on AMD64 As example via GOOS=linux GOARCH=arm GOARM=7 go build ./clients/cmd/docker-driver will build the docker-driver for arm/v7 on AMD64

Describe alternatives you've considered A Version for ARM64/v8 of the Loki docker plugin is on Docker hub available miacis/loki-docker-driver

I think this is something we'd be open to accepting a PR for, have a look at this in progress PR that's adding arm64 support for another component as an example.

Linking this for reference if anyone else stumbles upon this issue.

1973 is tracking a similar issue but for armv6 and armv7 due to its age (Apr 22, 2020)

I ran into some stability issues on arm using the docker driver so I switched over to journald which works very well for my setup. Pasting my config here for reference.

/etc/docker/daemon.json

{
  "log-driver": "journald",
  "log-opts": {
    "tag": "{{.Name}}/{{.ID}}"
  }
}

promtail.yaml

scrape_configs:
  - job_name: journald
    journal:
      max_age: 12h
      path: /var/log/journal
      labels:
        job: journald
    relabel_configs:
      - action: drop
        source_labels: [__journal__systemd_unit]
        regex: session-.*
      - source_labels: [__journal__hostname]
        target_label: hostname
      - source_labels: [__journal__boot_id]
        target_label: boot_id
      - source_labels: [__journal__systemd_unit]
        target_label: unit
      - source_labels: [__journal_priority]
        target_label: priority
      - source_labels: [__journal_container_name]
        target_label: container
      - source_labels: [__journal_container_id]
        target_label: container_id
      - source_labels: [__journal_image_name]
        target_label: image
    pipeline_stages:
      - match:
          selector: '{job="journald"} |= ".mount: Deactivated successfully."'
          action: drop

@peterhirn loki for us works well, in ARM, too: our issue is that we see it is running in "emulation" with x86_64-binfmt

ps aux | grep docker-driver
root     3548175 19.7  0.7 1985908 237248 ?      Ssl  09:30  27:24 /usr/libexec/qemu-binfmt/x86_64-binfmt-P /bin/docker-driver /bin/docker-driver

so we are sure this results in performance being pretty bad

Any updates? Hetzner arm servers are amazing, and on each of them playing with bulding the arm64 version of this plugin is tedious.
