Bitnami Secure Image for Etcd

What is Etcd?

etcd is a distributed key-value store designed to securely store data across a cluster. etcd is widely used in production on account of its reliability, fault-tolerance and ease of use.

Overview of Etcd Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement.

TL;DR

console
docker run -it --name etcd bitnami/etcd:latest

Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise OS Photon Linux. Why choose BSI images?

• Hardened secure images of popular open source software with Near-Zero Vulnerabilities
• Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
• Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
• Software supply chain provenance attestation through in-toto
• First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in our public catalog here. Note: Some data is only available with commercial subscriptions to BSI.

If you are looking for our previous generation of images based on Debian Linux, please see the Bitnami Legacy registry.

How to deploy Etcd in Kubernetes?

Deploying Bitnami applications as Helm Charts is the easiest way to get started with our applications on Kubernetes. Read more about the installation in the Bitnami Etcd Chart GitHub repository.

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

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

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.

Subscribe to project updates by watching the bitnami/containers GitHub repo.

Please note ARM support in branch 3.4 is experimental/unstable according to upstream docs, therefore branch 3.4 is only supported for AMD archs while branch 3.5 supports multiarch (AMD and ARM)

Prerequisites

To run this application you need Docker Engine >= 1.10.0. Docker Compose is recommended with a version 1.6.0 or later.

Get this image

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

console
docker pull bitnami/etcd: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.

console
docker pull bitnami/etcd:[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.

console
git clone [***]
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .

Connecting to other containers

Using Docker container networking, a Etcd server running inside a container can easily be accessed by your application containers using a Etcd client.

Containers attached to the same network can communicate with each other using the container name as the hostname.

Using the Command Line

In this example, we will create a Etcd client instance that will connect to the server instance that is running on the same docker network as the client.

Step 1: Create a network

console
docker network create app-tier --driver bridge

Step 2: Launch the Etcd server instance

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

console
docker run -d --name Etcd-server \
    --network app-tier \
    --publish 2379:2379 \
    --publish 2380:2380 \
    --env ALLOW_NONE_AUTHENTICATION=yes \
    --env ETCD_ADVERTISE_CLIENT_URLS=[***] \
    bitnami/etcd:latest

Step 3: Launch your Etcd client instance

Finally we create a new container instance to launch the Etcd client and connect to the server created in the previous step:

console
docker run -it --rm \
    --network app-tier \
    --env ALLOW_NONE_AUTHENTICATION=yes \
    bitnami/etcd:latest etcdctl --endpoints [***] put /message Hello

Using a Docker Compose file

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 Etcd server from your own custom application image which is identified in the following snippet by the service name myapp.

yaml
version: '2'

networks:
  app-tier:
    driver: bridge

services:
  Etcd:
    image: bitnami/etcd:latest
    environment:
      - ALLOW_NONE_AUTHENTICATION=yes
      - ETCD_ADVERTISE_CLIENT_URLS=[***]
    ports:
      - 2379:2379
      - 2380:2380
    networks:
      - app-tier
  myapp:
    image: YOUR_APPLICATION_IMAGE
    networks:
      - app-tier

IMPORTANT:

1. Please update the placeholder YOUR_APPLICATION_IMAGE in the above snippet with your application image
2. In your application container, use the hostname etcd to connect to the Etcd server

Launch the containers using:

console
docker-compose up -d

Configuration

The configuration can easily be setup by mounting your own configuration file on the directory /opt/bitnami/etcd/conf:

console
docker run --name Etcd -v /path/to/Etcd.conf.yml:/opt/bitnami/Etcd/conf/etcd.conf.yml bitnami/etcd:latest

After that, your configuration will be taken into account in the server's behaviour.

You can also do this by changing the docker-compose.yml file present in this repository:

yaml
Etcd:
  ...
  volumes:
    - /path/to/Etcd.conf.yml:/opt/bitnami/etcd/conf/etcd.conf.yml
  ...

You can find a sample configuration file on this link

Environment variables

Apart from providing your custom configuration file, you can also modify the server behavior via configuration as environment variables.

Customizable environment variables

Read-only environment variables

Additionally, you can configure etcd using the upstream env variables here

FIPS configuration in Bitnami Secure Images

The Bitnami Etcd Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

• OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Notable Changes

3.5.17-debian-12-r4

• Drop support for non-Helm cluster deployment. Upgrading of any kind including increasing replica count must also be done with helm upgrade exclusively. CD automation tools that respect Helm hooks such as ArgoCD can also be used.
• Remove prestop.sh script. Hence, container should no longer define lifecycle prestop hook.
• Add preupgrade.sh script which should be run as a pre-upgrade Helm hook. This replaces the prestop hook as a more reliable mechanism to remove stale members when replica count is decreased.
• Stop storing member ID in a local file which is unreliable. The container now check the member ID from the data dir instead.
• Stop storing/checking for member removal from a local file. The container now check with other members in the cluster instead.

3.4.15-debian-10-r7

• The container now contains the needed logic to deploy the Etcd container on Kubernetes using the Bitnami Etcd Chart.

3.4.13-debian-10-r7

• Arbitrary user ID(s) are supported again, see <[***]> for more information abut the changes in the upstream source code

3.4.10-debian-10-r0

• Arbitrary user ID(s) when running the container with a non-privileged user are not supported (only 1001 UID is allowed).
