$ docker run --name fluent-bit bitnami/fluent-bit:latest- 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.
- All Bitnami images available in Docker Hub are signed with Docker Content Trust (DCT). You can use
DOCKER_CONTENT_TRUST=1to verify the integrity of the images. - Bitnami container images are released on a regular basis with the latest distribution packages available.
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.

The recommended way to get the Bitnami Fluent Bit Docker Image is to pull the prebuilt image from the Docker Hub Registry.
$ docker pull bitnami/fluent-bit:latestTo 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/fluent-bit:[TAG]If you wish, you can also build the image yourself.
$ docker build -t bitnami/fluent-bit:latest 'https://github.com/bitnami/bitnami-docker-fluent-bit.git#master:1/debian-11'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 fluent-bit-network --driver bridgeUse the --network <NETWORK> argument to the docker run command to attach the container to the fluent-bit-network network.
$ docker run --name fluent-bit-node1 --network fluent-bit-network bitnami/fluent-bit:latestWe can launch another container 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.
When not specified, Docker Compose automatically sets up a new network and attaches all deployed services to that network. However, we will explicitly define a new bridge network named app-tier. In this example we assume that you want to connect to the Fluent Bit log processor from your own custom application image which is identified in the following snippet by the service name myapp.
version: '2'
networks:
app-tier:
driver: bridge
services:
fluent-bit:
image: 'bitnami/bitnami-docker-fluent-bit:latest'
networks:
- app-tier
myapp:
image: 'YOUR_APPLICATION_IMAGE'
networks:
- app-tierIMPORTANT:
- Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image
- In your application container, use the hostname
fluent-bitto connect to the Fluent Bit log processor
Launch the containers using:
$ docker-compose up -dFluent Bit is flexible enough to be configured either from the command line or through a configuration file. For production environments, Fluent Bit strongly recommends to use the configuration file approach.
Fluent Bit supports multiple extensions via plugins.
The Bitnami fluent-bit Docker image sends the container logs to the stdout. To view the logs:
$ docker logs fluent-bitYou 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.
We'd love for you to contribute to this container. You can request new features by creating an issue, or submit a pull request with your contribution.
If you encountered a problem running this container, you can file an issue. Be sure to include the following information in your issue:
- Host OS and version
- Docker version (
docker version) - Output of
docker info - Version of this container
- The command you used to run the container, and any relevant output you saw (masking any sensitive information)
Please, note this asset is a community-supported solution. This means that the Bitnami team is not actively working on new features/improvements nor providing support through GitHub Issues. Any new issue will stay open for 20 days to allow the community to contribute, after 15 days without activity the issue will be marked as stale being closed after 5 days.
The Bitnami team will review any PR that is created, feel free to create a PR if you find any issue or want to implement a new feature.
New versions and releases cadence are not going to be affected. Once a new version is released in the upstream project, the Bitnami container image will be updated to use the latest version, supporting the different branches supported by the upstream project as usual.
