Container image for Vault, a cross-platform secrets manager and authentication tool.
Chainguard Containers are regularly-updated, secure-by-default container images.
For those with access, this container image is available on cgr.dev
:
Be sure to replace the ORGANIZATION
placeholder with the name used for your organization's private repository within the Chainguard Registry.
The Chainguard image is designed to work as a drop-in replacement for the vault image.
This image supports the same environment variables, but has a number of key differences, including:
/etc/vault
/var/lib/vault
/var/log/vault
/usr/bin
Additionally, the Vault Chainguard image starts as the root user and
switches to the lower privileged vault
user in the entrypoint script.
The default entrypoint starts a single-node instance of the server in
development mode. Note that the container should be given the IPC_LOCK
capability:
If you run the container without IPC_LOCK
capability, you will receive a warning:
IPC_LOCK
is required for the memory lock (mlock
) feature that prevents memory — which could potentially contain sensitive information — from being written to disk. For a full explanation of how it works, refer to the official vault documentation.
To trun on this capability, include the --cap-add IPC_LOCK
argument:
You can alternatively configure a Security Context in Kubernetes:
This image and the vault-k8s
image can be used with the Helm chart. To replace the official images with the Chainguard images, provide the chart with the following values:
Assuming these values are saved in a file named cgr_values.yaml
, you should be able to apply them by running the following commands:
To configure Vault for production or other environments you can mount a configuration file to the /etc/vault
directory, as in this example:
You can also supply a vault configuration using the VAULT_LOCAL_CONFIG
variable, like this:
If using the file data storage plugin, we recommend that you configure it to write to /var/lib/vault
.
By default logs will be streamed to stdout and stderr, but can be configured to write to
/var/log/vault
.
Chainguard's free tier of Starter container images are built with Wolfi, our minimal Linux undistro.
All other Chainguard Containers are built with Chainguard OS, Chainguard's minimal Linux operating system 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 development, or -dev
, variant.
In all other cases, including Chainguard Containers tagged as :latest
or with a specific version number, the container images include only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager.
Although the -dev
container image variants have similar security features as their more minimal versions, they include additional software that is typically not necessary in production environments. We recommend using multi-stage builds to copy artifacts from the -dev
variant into a more minimal production image.
To improve security, Chainguard Containers include only essential dependencies. Need more packages? Chainguard customers can use Custom Assembly to add packages, either through the Console, chainctl
, or API.
To use Custom Assembly in the Chainguard Console: navigate to the image you'd like to customize in your Organization's list of images, and click on the Customize image button at the top of the page.
