- Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
- With Bitnami images the latest bug fixes and features are available as soon as possible.
- Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
- All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.
- Bitnami container images are released daily with the latest distribution packages available.
This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.
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.
You can find an example for testing in the file test.yaml
. To launch this sample file run:
$ kubectl apply -f test.yaml
NOTE: If you are pulling from a private containers registry, replace the image name with the full URL to the docker image. E.g.
- image: 'your-registry/image-name:your-version'
NOTE: Debian 8 images have been deprecated in favor of Debian 9 images. Bitnami will not longer publish new Docker images based on Debian 8.

The recommended way to get the Bitnami Blackbox Exporter Docker Image is to pull the prebuilt image from the Docker Hub Registry.
$ docker pull bitnami/blackbox-exporter:latest
To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.
$ docker pull bitnami/blackbox-exporter:[TAG]
If you wish, you can also build the image yourself.
$ docker build -t bitnami/blackbox-exporter:latest https://github.com/bitnami/bitnami-docker-blackbox-exporter.git
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.
$ docker network create blackbox-exporter-network --driver bridge
Use the --network <NETWORK>
argument to the docker run
command to attach the container to the blackbox-exporter-network
network.
$ docker run --name blackbox-exporter-node1 --network blackbox-exporter-network bitnami/blackbox-exporter:latest
We can launch another 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.
Blackbox exporter is configured via a configuration file and command-line flags (such as what configuration file to load, what port to listen on, and the logging format and level).
The default location for the config file is /opt/bitnami/blackbox-exporter/conf/config.yml
, you can mount a volume there in order to overwrite it.
The file is written in YAML format, defined by the scheme described below. Brackets indicate that a parameter is optional. For non-list parameters the value is set to the specified default.
Generic placeholders are defined as follows:
<boolean>
: a boolean that can take the values true or false
<int>
: a regular integer
<duration>
: a duration matching the regular expression [0-9]+(ms|[smhdwy])
<filename>
: a valid path in the current working directory
<string>
: a regular string
<secret>
: a regular string that is a secret, such as a password
<regex>
: a regular expression
The other placeholders are specified separately.
Example config:
scrape_configs:
- job_name: 'blackbox'
metrics_path: /probe
params:
module: [http_2xx] # Look for a HTTP 200 response.
static_configs:
- targets:
- http://prometheus.io # Target to probe with http.
- https://prometheus.io # Target to probe with https.
- http://example.com:8080 # Target to probe with http on port 8080.
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: 127.0.0.1:9115 # The blackbox exporter's real hostname:port.
The Bitnami blackbox-exporter Docker image sends the container logs to the stdout
. To view the logs:
$ docker logs blackbox-exporter
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.
Bitnami provides up-to-date versions of blackbox-exporter, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.
$ docker pull bitnami/blackbox-exporter:latest
Stop the currently running container using the command
$ docker stop blackbox-exporter
Next, take a snapshot of the persistent volume /path/to/blackbox-exporter-persistence
using:
$ rsync -a /path/to/blackbox-exporter-persistence /path/to/blackbox-exporter-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
You can use this snapshot to restore the database state should the upgrade fail.
$ docker rm -v blackbox-exporter
Re-create your container from the new image, restoring your backup if necessary.
$ docker run --name blackbox-exporter bitnami/blackbox-exporter:latest
