Latest Prometheus as a container image for learning, experimentation, and using copying into multi-stage images.
docker build . -t prometheus
# load your machine's IP address into a variable - on Windows:
$hostIP = $(Get-NetIPConfiguration | Where-Object {$_.IPv4DefaultGateway -ne $null }).IPv4Address.IPAddress
# on Linux:
hostIP=$(ip route get 1 | awk '{print $NF;exit}')
# and on Mac:
hostIP=$(ifconfig en0 | grep -e 'inet\s' | awk '{print $2}')
# pass your IP address as an environment variable for the container:
docker container run -e DOCKER_HOST=$hostIP -d -p 9090:9090 prometheus:2.13.1
The configuration in thePrometheus image uses the DOCKER_HOST IP address to talk to your host machine and collect the metrics you’ve configured in the Docker Engine. It’s rare that you’ll need to access a service on the host from inside the container, and if you do, you would usually use your server name and Docker would find the IP address. In a development environment that might not work, but the IP address approach should be fine.
Browse to http://localhost:9090 and you’ll see the Prometheus web interface.
