Chainguard Container for zookeeper
Minimal image with Apache Zookeeper.
Chainguard Containers are regularly-updated, secure-by-default container images.
Download this Container Image
For those with access, this container image is available on cgr.dev:
docker pull cgr.dev/ORGANIZATION/zookeeper:latest
Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.
IMPORTANT - Please read!
On 12/10/2024, Bitnami updated their Helm charts to reject non-Bitnami images by
default. To disable this behavior and use Chainguard images, you must specify
the following parameter:
global.security.allowInsecureImages: true
For more information, please refer to the bitnami change notification.
Deploy using helm
The example below demonstrates how to deploy a Chainguard image using the
Bitnami zookeeper Helm chart:
helm repo add bitnami https://charts.bitnami.com/bitnami
helm install zookeeper bitnami/zookeeper \
--namespace zookeeper \
--create-namespace \
--set global.security.allowInsecureImages=true \
--set image.registry="cgr.dev" \
--set image.repository="cgr.dev/ORGANIZATION/zookeeper-bitnami" \
--set image.tag="latest"
Using Zookeeper
To run Zookeeper image with the sample configuration, use:
$ docker container run -d -e ZOO_ENABLE_AUTH=no -e ALLOW_ANONYMOUS_LOGIN=yes -e ZOO_4LW_COMMANDS_WHITELIST='*' -p 2181:2181 cgr.dev/chainguard/zookeeper:latest
ZooKeeper JMX enabled by default

What are Chainguard Containers?
Chainguard Containers are minimal container images that are secure by default.
In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.
The main features of Chainguard Containers include:
For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.
Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
