Alpine-Grafana

Container for Alpine Linux + S6 + Grafana

---

This image serves as a monitor/visualization dashboard server using Grafana. Usually coupled with my alpine-influxdb image, using alpine-netdata to collect the metrics.

Based on Alpine Linux from my alpine-glibc image with the s6 init system overlayed in it.

Auto updated according to the github releases.

The image is tagged respectively for the following architectures,

• armhf - grafana-armhf sourced from here
• x86_64 (retagged as the latest )

armhf builds have embedded binfmt_misc support and contain the qemu-user-static binary that allows for running it also inside an x64 environment that has it.

---

Get the Image

---

Pull the image for your architecture it's already available from Docker Hub.

# make pull
docker pull woahbase/alpine-grafana:x86_64

---

Run

---

If you want to run images for other architectures, you will need to have binfmt support configured for your machine. multiarch, has made it easy for us containing that into a docker container.

# make regbinfmt
docker run --rm --privileged multiarch/qemu-user-static:register --reset

Without the above, you can still run the image that is made for your architecture, e.g for an x86_64 machine..

This image already has a user grafana configured to drop privileges to the passed PUID/PGID which is ideal if its used to run in non-root mode. That way you only need to specify the values at runtime and pass the -u grafana if need be. (run id in your terminal to see your own PUID/PGID values.)

Running make starts the service.

# make
docker run --rm -it \
  --name docker_grafana --hostname grafana \
  -e PGID=1000 -e PUID=1000 \
  -p 3000:3000 \
  -v data:/var/lib/grafana/data \
  -v conf:/var/lib/grafana/conf \
  -v /etc/hosts:/etc/hosts:ro \
  -v /etc/localtime:/etc/localtime:ro \
  woahbase/alpine-grafana:x86_64

Stop the container with a timeout, (defaults to 2 seconds)

# make stop
docker stop -t 2 docker_grafana

Removes the container, (always better to stop it first and -f only when needed most)

# make rm
docker rm -f docker_grafana

Restart the container with

# make restart
docker restart docker_grafana

---

Shell access

---

Get a shell inside a already running container,

# make shell
docker exec -it docker_grafana /bin/bash

set user or login as root,

# make rshell
docker exec -u root -it docker_grafana /bin/bash

To check logs of a running container in real time

# make logs
docker logs -f docker_grafana

---

Development

---

If you have the repository access, you can clone and build the image yourself for your own system, and can push after.

---

Setup

---

Before you clone the repo, you must have Git, GNU make, and Docker setup on the machine.

git clone https://github.com/woahbase/alpine-grafana
cd alpine-grafana

You can always skip installing make but you will have to type the whole docker commands then instead of using the sweet make targets.

---

Build

---

You need to have binfmt_misc configured in your system to be able to build images for other architectures.

Otherwise to locally build the image for your system. [ARCH defaults to x86_64, need to be explicit when building for other architectures.]

# make ARCH=x86_64 build
# sets up binfmt if not x86_64
docker build --rm --compress --force-rm \
  --no-cache=true --pull \
  -f ./Dockerfile_x86_64 \
  --build-arg ARCH=x86_64 \
  --build-arg DOCKERSRC=alpine-glibc \
  --build-arg PGID=1000 \
  --build-arg PUID=1000 \
  --build-arg USERNAME=woahbase \
  -t woahbase/alpine-grafana:x86_64 \
  .

It may take a bit of time to start it. To check if its working..

# make ARCH=x86_64 test
docker run --rm -it \
  --name docker_grafana --hostname grafana \
  -e PGID=1000 -e PUID=1000 \
  woahbase/alpine-grafana:x86_64 \
  sh -ec 'sleep 15; grafana-server -v'

And finally, if you have push access,

# make ARCH=x86_64 push
docker push woahbase/alpine-grafana:x86_64
