Bitnami Docker Image for Kibana

What is Kibana?

Kibana is an open source, browser based analytics and search dashboard for Elasticsearch. Kibana is a snap to setup and start using. Kibana strives to be easy to get started with, while also being flexible and powerful, just like Elasticsearch

TL;DR;

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-kibana/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Why use Bitnami Images?

• 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 (DTC). You can use DOCKER_CONTENT_TRUST=1 to verify the integrity of the images.
• 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.

How to deploy Kibana in Kubernetes?

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'

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

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.

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

Get this image

The recommended way to get the Bitnami Kibana Docker Image is to pull the prebuilt image from the Docker Hub Registry.

$ docker pull bitnami/kibana: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/kibana:[TAG]

If you wish, you can also build the image yourself.

$ docker build -t bitnami/kibana:latest 'https://github.com/bitnami/bitnami-docker-kibana.git#master:7/debian-9'

How to use this image

Run the application using Docker Compose

The main folder of this repository contains a functional docker-compose.yml file. Run the application using it as shown below:

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-kibana/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Run the application manually

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

1. Create a new network for the application and the database:

$ docker network create kibana_network

2. Run the Elasticsearch container:

$ docker run -d -p 9200:9200 --name elasticsearch --net=kibana_network bitnami/elasticsearch

3. Run the Kibana container:

$ docker run -d -p 5601:5601 --name kibana --net=kibana_network \
  -e KIBANA_ELASTICSEARCH_URL=elasticsearch \
  bitnami/kibana

Then you can access your application at http://your-ip:5601/

Persisting your application

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

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the Elasticsearch data.

The above examples define docker volumes namely elasticsearch_data and kibana_data. The Kibana application state will persist as long as these volumes are not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

$ docker run -v /path/to/kibana-persistence:/bitnami bitnami/kibana:latest

or modifying the docker-compose.yml file present in this repository:

kibana:
  ...
  volumes:
    - /path/to/kibana-persistence:/bitnami
  ...

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 Kibana server running inside a container can easily be accessed by your application containers.

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

$ docker network create app-tier --driver bridge

Step 2: Launch the Kibana server instance

Use the --network app-tier argument to the docker run command to attach the Kibana container to the app-tier network.

$ docker run -d --name kibana-server \
    --network app-tier \
    bitnami/kibana:latest

Step 3: Launch your application container

$ docker run -d --name myapp \
    --network app-tier \
    YOUR_APPLICATION_IMAGE

IMPORTANT:

1. Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image
2. In your application container, use the hostname kibana-server to connect to the Kibana server

Using Docker Compose

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 Kibana server 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:
  kibana:
    image: 'bitnami/kibana:latest'
    networks:
      - app-tier
  myapp:
    image: 'YOUR_APPLICATION_IMAGE'
    networks:
      - app-tier

IMPORTANT:

1. Please update the YOUR_APPLICATION_IMAGE_ placeholder in the above snippet with your application image
2. In your application container, use the hostname kibana to connect to the Kibana server

Launch the containers using:

$ docker-compose up -d

Configuration

Initializing a new instance

When the container is executed for the first time, it will execute the files with extension .sh, located at /docker-entrypoint-initdb.d.

In order to have your custom files inside the docker image you can mount them as a volume.

Configuration file

The image looks for configurations in /bitnami/kibana/conf/. As mentioned in Persisting your application you can mount a volume at /bitnami and copy/edit the configurations in the /path/to/kibana-persistence/kibana/conf/. The default configurations will be populated to the conf/ directory if it's empty.

Step 1: Run the Kibana image

Run the Kibana image, mounting a directory from your host.

$ docker run --name kibana -v /path/to/kibana-persistence:/bitnami bitnami/kibana:latest

or modifying the docker-compose.yml file present in this repository:

kibana:
  ...
  volumes:
    - /path/to/kibana-persistence:/bitnami
  ...

Step 2: Edit the configuration

Edit the configuration on your host using your favorite editor.

$ vi /path/to/kibana-persistence/kibana/conf/kibana.conf

Step 3: Restart Kibana

After changing the configuration, restart your Kibana container for changes to take effect.

$ docker restart kibana

or using Docker Compose:

$ docker-compose restart kibana

Refer to the configuration manual for the complete list of configuration options.

Logging

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

$ docker logs kibana

or using Docker Compose:

$ docker-compose logs kibana

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 Kibana, 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

$ docker pull bitnami/kibana:latest

or if you're using Docker Compose, update the value of the image property to bitnami/kibana:latest.

Step 2: Stop and backup the currently running container

Stop the currently running container using the command

$ docker stop kibana

or using Docker Compose:

$ docker-compose stop kibana

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

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

Additionally, snapshot the Elasticsearch data

You can use these snapshots to restore the application state should the upgrade fail.

Step 3: Remove the currently running container

$ docker rm -v kibana

or using Docker Compose:

$ docker-compose rm -v kibana

Step 4: Run the new image

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

$ docker run --name kibana bitnami/kibana:latest

or using Docker Compose:

$ docker-compose up kibana

Notable Changes

6.5.1-r3 & 5.6.13-r20

• The Kibana container has been migrated to a non-root user approach. Previously the container ran as the root user and the Kibana daemon was started as the kibana user. From now on, both the container and the Kibana daemon run as user 1001. As a consequence, the data directory must be writable by that user. You can revert this behavior by changing USER 1001 to USER root in the Dockerfile.

4.5.4-r1

• ELASTICSEARCH_URL parameter has been renamed to KIBANA_ELASTICSEARCH_URL.
• ELASTICSEARCH_PORT parameter has been renamed to KIBANA_ELASTICSEARCH_PORT.
