Grafana Docker Compose files

Docker Compose files to spin up an instance of Grafana FIXME capitalization FIXME.

How to run

Add a COMPOSE_ENV file and save its location as a shell variable along with the location where this repo lives, here for example /opt/containers/grafana plus all other variables. At env/fqdn_context.env.example you'll find an example environment file.

When everything's ready start Grafana with Docker Compose, otherwise head down to Initial setup first.

Environment

export COMPOSE_DIR='/opt/containers/grafana'
export COMPOSE_CTX='ux_vilnius'
export COMPOSE_PROJECT='grafana-'"${COMPOSE_CTX}"
export COMPOSE_FILE="${COMPOSE_DIR}"'/compose.yaml'
export COMPOSE_ENV=<add accordingly>

Context

On your deployment machine create the necessary Docker context to connect to and control the Docker daemon on whatever target host you'll be using, for example:

docker context create fully.qualified.domain.name --docker 'host=ssh://root@fully.qualified.domain.name'

Pull

Pull images from Docker Hub verbatim.

docker compose --project-name "${COMPOSE_PROJECT}" --file "${COMPOSE_FILE}" --env-file "${COMPOSE_ENV}" --profile 'full' pull

Copy to target

Copy images to target Docker host, that is assuming you deploy to a machine that itself has no network route to reach Docker Hub. Copying in its simplest form involves a local docker save and a remote docker load. Consider the helper mini-project quico.space/Quico/copy-docker where copy-docker.sh allows the following workflow:

source "${COMPOSE_ENV}"
# FIXME Docker Hub image name with or without slash? FIXME
for image in 'grafana:'"${GRAFANA_VERSION}" 'nginx:'"${NGINX_VERSION}"; do
    copy-docker.sh "${image}" fully.qualified.domain.name
done

Start

docker --context 'fully.qualified.domain.name' compose --project-name "${COMPOSE_PROJECT}" --file "${COMPOSE_FILE}" --env-file "${COMPOSE_ENV}" --profile 'full' up --detach

Initial setup

We're assuming you run Docker Compose workloads with ZFS-based bind mounts. ZFS management, creating a zpool and setting adequate properties for its datasets is out of scope of this document.

Datasets

Create ZFS datasets and set permissions as needed.

  • Parent dateset

    zfs create -o mountpoint=/opt/docker-data 'zpool/docker-data'
    
  • Container-specific datasets

    zfs create -p 'zpool/docker-data/grafana-'"${COMPOSE_CTX}"'/grafana/data/db'
    zfs create -p 'zpool/docker-data/grafana-'"${COMPOSE_CTX}"'/grafana/data/logs'
    zfs create -p 'zpool/docker-data/grafana-'"${COMPOSE_CTX}"'/grafana/config'
    zfs create -p 'zpool/docker-data/grafana-'"${COMPOSE_CTX}"'/nginx/data/db'
    zfs create -p 'zpool/docker-data/grafana-'"${COMPOSE_CTX}"'/nginx/data/logs'
    zfs create -p 'zpool/docker-data/grafana-'"${COMPOSE_CTX}"'/nginx/config'
    

    FIXME When changing bind mount locations to real ones remember to also update volumes: in compose.yaml FIXME

  • Create subdirs

    mkdir -p '/opt/docker-data/grafana-'"${COMPOSE_CTX}"'/grafana/'{'.ssh','config','data','projects'}
    
  • Change ownership

    chown -R 1000:1000 '/opt/docker-data/grafana-'"${COMPOSE_CTX}"'/grafana/data/'*
    

Additional files

Place the following files on target server. Use the directory structure at build-context as a guide, specifically at docker-data.

FIXME Add details about files that aren't self-explanatory FIXME

build-context/
