  Healthcheck instructions have not been added to container images
    Resource: /images/benchmarks/nginx/Dockerfile. | Checkov ID: CKV_DOCKER_2

Description

We recommend that you add the HEALTHCHECK instruction to your Docker container images to ensure that health checks are executed against running containers.
An important security control is that of availability.
Adding the HEALTHCHECK instruction to your container image ensures that the Docker engine periodically checks the running container instances against that instruction to ensure that containers are still operational.
Based on the results of the health check, the Docker engine could terminate containers which are not responding correctly, and instantiate new ones.

  A user for the container has not been created
    Resource: /images/benchmarks/nginx/Dockerfile. | Checkov ID: CKV_DOCKER_3

Description

Containers should run as a non-root user.
It is good practice to run the container as a non-root user, where possible.
This can be done either via the USER directive in the Dockerfile or through gosu or similar where used as part of the CMD or ENTRYPOINT directives.
