Dockerfile Linting is a process to check and modify the Dockerfile as per the industry's best practices.
Haskell Dockerfile Linter aka Hadolint is a Haskell-based linter to help developers stick to best practices while creating Dockerfiles.
A Dockerfile is provided in the home directory of the root user (i.e. /root). Hadolint is installed on the machine.
Objective: Analyze the Dockerfile with Hadolint. Edit Dockerfile to remove all issues detected by Hadolint!
- Use "hadolint" command to invoke Hadolint tool
- vim and nano editors are installed on the machine and can be used to edit the Dockerfile

Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email firstname.lastname@example.org clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
