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}"'/docker-compose.yml'
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 docker-compose.yml 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
