Docker image for Shellcheck
ShellCheck is a GPLv3 tool that gives warnings and suggestions for bash/sh shell scripts:
The goals of ShellCheck are:
- To point out and clarify typical beginner’s syntax issues that cause a shell to give cryptic error messages.
- To point out and clarify typical intermediate level semantic problems that cause a shell to behave strangely and counter-intuitively.
- To point out subtle caveats, corner cases and pitfalls that may cause an advanced user’s otherwise working script to fail under future circumstances.
You can see the cli reference here.

Continuous Integration Services
For each of the following services, you can see an example of this image in that environment:
Tagging Strategy
Every new release of the image includes three tags: version, date and latest. These tags can be described as such:
latest: The most-recently released version of an image. (cardboardci/shellcheck:latest)<version>: The most-recently released version of an image for that version of the tool. (cardboardci/shellcheck:1.0.0)<version-date>: The version of the tool released on a specific date (cardboarci/awscli:1.0.0-20190101)
We recommend using the digest for the docker image, or pinning to the version-date tag. If you are unsure how to get the digest, you can retrieve it for any image with the following command:
docker pull cardboardci/shellcheck:latest
docker inspect --format='{{index .RepoDigests 0}}' cardboardci/shellcheck:latest
Fundamentals
All images in the CardboardCI namespace are built from cardboardci/ci-core. This image ensures that the base environment for every image is always up to date. The common base image provides dependencies that are often used building and deploying software.
By having a common base, it means that each image is able to focus on providing the optimal tooling for each development workflow.
