Bitnami container image for Alertmanager
10M+
The Alertmanager handles alerts sent by client applications such as the Prometheus server. It takes care of deduplicating, grouping, and routing them to the correct receiver integrations.

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.
Starting December 10th 2024, only the latest stable branch of any container will receive updates in the free Bitnami catalog. To access up-to-date releases for all upstream-supported branches, consider upgrading to Bitnami Premium. Previous versions already released will not be deleted. They are still available to pull from DockerHub.
Please check the Bitnami Premium page in our partner Arrow Electronics for more information.

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
.

The recommended way to get the Bitnami Alertmanager Docker Image is to pull the prebuilt image from the Docker Hub Registry.
docker pull bitnami/alertmanager: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/alertmanager:[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.
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .
If you remove the container all your data and configurations 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 persist even after the container is removed.
For persistence you should mount a volume at the /opt/bitnami/alertmanager/data
path. The above examples define a docker volume namely alertmanager_data
. The Alertmanager application state will persist as long as this volume is not removed.
To avoid inadvertent removal of this volume 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/alertmanager-persistence:/opt/bitnami/alertmanager/data bitnami/alertmanager:latest
NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID
1001
.
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.
Step 1: Create a network
docker network create alertmanager-network --driver bridge
Step 2: Launch the Alertmanager container within your network
Use the --network <NETWORK>
argument to the docker run
command to attach the container to the alertmanager-network
network.
docker run --name alertmanager-node1 --network alertmanager-network bitnami/alertmanager:latest
Step 3: Run another containers
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.
The configuration can easily be setup by mounting your own configuration file on the directory /opt/bitnami/alertmanager/conf/
:
docker run --name alertmanager -v /path/to/config.yml:/opt/bitnami/alertmanager/conf/config.yml bitnami/alertmanager:latest
After that, your configuration will be taken into account in the server's behaviour.
Using Docker Compose:
version: '2'
services:
alertmanager:
image: bitnami/alertmanager:latest
volumes:
- /path/to/config.yml:/opt/bitnami/alertmanager/conf/config.yml
Configuration is yaml based. The full documentation of the configuration can be found here.
amtool
is a cli tool for interacting with the alertmanager api. It is bundled with all releases of alertmanager.
The Bitnami alertmanager Docker image sends the container logs to the stdout
. To view the logs:
docker logs alertmanager
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 alertmanager, 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/alertmanager:latest
Step 2: Stop and backup the currently running container
Stop the currently running container using the command
docker stop alertmanager
Next, take a snapshot of the persistent volume /path/to/alertmanager-persistence
using:
rsync -a /path/to/alertmanager-persistence /path/to/alertmanager-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
docker rm -v alertmanager
Step 4: Run the new image
Re-create your container from the new image, restoring your backup if necessary.
docker run --name alertmanager bitnami/alertmanager:latest
