The documentation referenced "data volume containers", which were superseded by named volume support in Docker several years ago. There were to bind-mounting examples in the docs that are effectively doing the same thing, but the description of the second was somewhat erroneous.

Installation
Using pre-compiled binaries
We provide precompiled binaries for most official Prometheus components. Check out the download section for a list of all available versions.
From source
For building Prometheus components from source, see the Makefile targets in
the respective repository.
Using Docker
All Prometheus services are available as Docker images on Quay.io or Docker Hub.
Running Prometheus on Docker is as simple as docker run -p 9090:9090 prom/prometheus. This starts Prometheus with a sample
configuration and exposes it on port 9090.
The Prometheus image uses a volume to store the actual metrics. For production deployments it is highly recommended to use a named volume to ease managing the data on Prometheus upgrades.
To provide your own configuration, there are several options. Here are two examples.
Volumes & bind-mount
Bind-mount your prometheus.yml from the host by running:
docker run \
-p 9090:9090 \
-v /path/to/prometheus.yml:/etc/prometheus/prometheus.yml \
prom/prometheus
Or bind-mount the directory containing prometheus.yml onto
/etc/prometheus by running:
docker run \
-p 9090:9090 \
-v /path/to/config:/etc/prometheus \
prom/prometheus
Custom image
To avoid managing a file on the host and bind-mount it, the configuration can be baked into the image. This works well if the configuration itself is rather static and the same across all environments.
For this, create a new directory with a Prometheus configuration and a
Dockerfile like this:
FROM prom/prometheus
ADD prometheus.yml /etc/prometheus/
Now build and run it:
docker build -t my-prometheus .
docker run -p 9090:9090 my-prometheus
A more advanced option is to render the configuration dynamically on start with some tooling or even have a daemon update it periodically.
