Docker 19.03 enables TLS by default: ``` Starting in 18.09+, the dind variants of this image will automatically generate TLS certificates in the directory specified by the DOCKER_TLS_CERTDIR environment variable. Warning: in 18.09, this behavior is disabled by default (for compatibility). If you use --network=host, shared network namespaces (as in Kubernetes pods), or otherwise have network access to the container (including containers started within the dind instance via their gateway interface), this is a potential security issue (which can lead to access to the host system, for example). It is recommended to enable TLS by setting the variable to an appropriate value (-e DOCKER_TLS_CERTDIR=/certs or similar). In 19.03+, this behavior is enabled by default. ``` Update the example to use docker over TLS.
