Bitnami Secure Image for Prometheus

What is Prometheus?

Prometheus is an open source monitoring and alerting system. It enables sysadmins to monitor their infrastructures by collecting metrics from configured targets at given intervals.

Overview of Prometheus Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

TL;DR

console
docker run --name prometheus bitnami/prometheus:latest

Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise https://vmware.github.io/photon/. Why choose BSI images?

• Hardened secure images of popular open source software with Near-Zero Vulnerabilities
• Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
• Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
• Software supply chain provenance attestation through in-toto
• First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in our public catalog here. Note: Some data is only available with commercial subscriptions to BSI.

If you are looking for our previous generation of images based on Debian Linux, please see the https://hub.docker.com/u/bitnamilegacy.

Why use a non-root container?

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Supported tags and respective Dockerfile links

Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags in our documentation page.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml.

Get this image

The recommended way to get the Bitnami Prometheus Docker Image is to pull the prebuilt image from the https://hub.docker.com/r/bitnami/prometheus.

console
docker pull bitnami/prometheus:latest

To use a specific version, you can pull a versioned tag. You can view the https://hub.docker.com/r/bitnami/prometheus/tags/ in the Docker Hub Registry.

console
docker pull bitnami/prometheus:[TAG]

If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build command. Remember to replace the APP, VERSION and OPERATING-SYSTEM path placeholders in the example command below with the correct values.

console
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Persisting your database

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will add persistance even after the container is removed.

For persistence, mount a directory at the /opt/bitnami/prometheus/data path. If the mounted directory is empty, it will be initialized on the first run.

console
docker run --name prometheus \
    -v /path/to/prometheus-persistence:/opt/bitnami/prometheus/data \
    bitnami/prometheus:latest

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Connecting to other containers

Using Docker container networking, a different server running inside a container can easily be accessed by your application containers and vice-versa.

Containers attached to the same network can communicate with each other using the container name as the hostname.

Using the Command Line

Step 1: Create a network

console
docker network create prometheus-network --driver bridge

Step 2: Launch the Prometheus container within your network

Use the --network <NETWORK> argument to the docker run command to attach the container to the prometheus-network network.

console
docker run --name prometheus-node1 --network prometheus-network bitnami/prometheus:latest

Step 3: Run other containers

We can launch other containers using the same flag (--network NETWORK) in the docker run command. If you also set a name to your container, you will be able to use it as hostname in your network.

Configuration

Prometheus is configured via command-line flags and a configuration file. While the command-line flags configure immutable system parameters (such as storage locations, amount of data to keep on disk and in memory, listening address, etc.), the configuration file defines everything related to scraping jobs and their instances, as well as which rule files to load.

Prometheus can reload its configuration at runtime. If the new configuration is not well-formed, the changes will not be applied. A configuration reload is triggered by sending a SIGHUP to the Prometheus process or sending a HTTP POST request to the /-/reload endpoint (when the --web.enable-lifecycle flag is enabled). This will also reload any configured rule files.

Further information

Command-Line Flags

You can add new flags to the ones already in use by default, which are passed to Prometheus through the CMD instruction in the Dockerfile.

To view all available command-line flags, run docker run bitnami/prometheus:latest -h.

Configuration file

You can overwrite the default configuration file with your custom prometheus.yml. Create a custom conf file and mount it at /opt/bitnami/prometheus/conf/prometheus.yml like so:

console
docker run --name prometheus \
    -v path/to/prometheus.yml:/opt/bitnami/prometheus/conf/prometheus.yml \
    bitnami/prometheus:latest

FIPS configuration in Bitnami Secure Images

The Bitnami Prometheus Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

• OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Logging

The Bitnami Prometheus Docker image sends the container logs to the stdout. To view the logs:

console
docker logs prometheus

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

Maintenance

Upgrade this image

Bitnami provides up-to-date versions of prometheus, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.

Step 1: Get the updated image

console
docker pull bitnami/prometheus:latest

Step 2: Stop and backup the currently running container

Stop the currently running container using the command

console
docker stop prometheus

Next, take a snapshot of the persistent volume /path/to/prometheus-persistence using:

console
rsync -a /path/to/prometheus-persistence /path/to/prometheus-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

You can use this snapshot to restore the database state should the upgrade fail.

Step 3: Remove the currently running container

console
docker rm -v prometheus

Step 4: Run the new image

Re-create your container from the new image, if necessary.

console
docker run --name prometheus bitnami/prometheus:latest

Notable Changes

Starting January 16, 2024

• The docker-compose.yaml file has been removed, as it was solely intended for internal testing purposes.
