mjeromin/prometheus repository overview

⁠docker-prometheus

Docker image for Prometheus⁠ built from source. It is based on the official prometheus/prometheus⁠ Dockerfile.

• mjeromin/prometheus:

⁠Usage

You can build a docker image with

docker image build -f Dockerfile -t mjeromin/prometheus .

This will pull the prometheus source code from github and make build inside an Alpine/Go environment. The final artifacts are copied into an Alpine base image.

The docker build accepts a some optional build arguments, including

• GIT_REPO: the prometheus source code git repository (default: github.com/prometheus/prometheus.git⁠)
• GIT_TAG: the git tag (default: v2.3.2)

⁠Running the docker image

You can launch a Prometheus container with

$ docker container run --name prometheus -d -p 127.0.0.1:9090:9090 mjeromin/prometheus

Prometheus will now be reachable at http://localhost:9090/⁠.

You can override the example configuration with your own via volume mapping. For example:

$ docker container run --name prometheus -d -p 127.0.0.1:9090:9090 -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml:ro mjeromin/prometheus

This is assuming /tmp/prometheus.yml is where you are storing your local configuration. Alternatively, you can avoid volume mapping and bake the configuration into downstream images

FROM mjeromin/prometheus

COPY /tmp/prometheus.yml /etc/prometheus/prometheus.yml
