Keeping these artifacts in the base image, which may be used for production, results in an increased Docker image size, and this can badly affect the time spent downloading it as well as increase the attack surface because more packages are installed as a result. Youll need to trust the certificate authority file fixtures/root-ca.crt in the repository before clients can successfully connect.
