Chainguard Containers are regularly-updated, secure-by-default container images.
For those with access, this container image is available on cgr.dev
:

The Chainguard Apache Tomcat image is meant to serve as a drop-in replacement for the official Tomcat image.
Like most of Chainguard's images, this image does not operate as the root user and includes only the minimum packages needed to function.
To start up the tomcat
server:
This shows you the Apache Tomcat log output as the server boots, so you can check for any errors and confirm that Tomcat is running.
If you are running this container on your local machine for testing, you can modify the original docker run
by forwarding requests to a port on your host machine to one of the container's ports. This enables you to connect to the Tomcat server using your host computer's browser:
This again shows the Apache Tomcat log output as the server boots.
Now browse to http://localhost:8080
to see an Apache Tomcat 404 error page. Tomcat will return a 404 error because, by default, Tomcat ships with an empty webapps
directory. Regardless, what you will see is a confirmation that the Tomcat server is running.
You can find the official Tomcat documentation on the Apache Tomcat website.
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.
