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.
