Run Docker
To run this container locally, use the --net=host
flag.
The Makefile can also help running Docker images.
If you download this repository on Linux, you should be able to run the container with:
ARGS="--grafana-url=http://localhost:3000 --prometheus-urls=http://localhost:9090 --grafana-key=xyz=" make docker-run
on MacOS the command is slightly differnt:
ARGS="--grafana-url=http://host.docker.internal:3000 --prometheus-urls=http://host.docker.internal:9090 --grafana-key=xyz=" make docker-run
If you need to run Docker from scratch you should use a different command.
Linux
$ docker run --net=host --rm -e GRAFANA_URL=http://localhost:3000 -e PROMETHEUS_URLS=http://localhost:9090 -e GRAFANA_KEY=xyz containersol/prom-metrics-check:latest
MacOS
$ docker run --net=host --rm -e GRAFANA_URL=http://host.docker.internal:3000 -e PROMETHEUS_URLS=http://host.docker.internal:9090 -e GRAFANA_KEY=xyz containersol/prom-metrics-check:latest
