 # runh
 
-`run` is a CLI tool for spawning and running RustyHermit containers.
-To start RustyHermit application within a isolated lightweight virtual machine, a directory with the application and the loader must be created.
-In this example, the binaries will be downloaded from a docker registry.
+`runh` is a CLI tool for spawning and running HermitOS containers.
+To start HermitOS application within a isolated lightweight virtual machine, a container registry with the the HermitOS application and its loader.
 
-At first, the required tools will be downloaded and installed to run RustyHermit images.
+To create a container image with the httpd example from the [HermitOS](https://github.com/hermit-os/hermit-rs) repository, the following `Dockerfile` is used.
+The example assumes, that `httpd` and `hermit-loader-x86_64` is already created and copied to the directory, which contains the `Dockerfile`.
 
-```sh
-$ docker export $(docker create ghcr.io/hermit-os/hermit_env:latest) > hermit-env.tar
-$ sudo mkdir -p /run/runh/hermit
-$ sudo tar -xf hermit-env.tar -C /run/runh/hermit
-```
-
-Afterwards, the RustyHermit application will be download and store in a local directory.
-
-```sh
-$ docker export $(docker create ghcr.io/hermit-os/rusty_demo:latest) > runh-image.tar
-$ mkdir -p ./runh-image/rootfs
-$ tar -xf runh-image.tar -C ./runh-image/rootfs
-```
-
-In this case, the application an the loader is stored in the subdirectory `runh-image/rootfs`.
-
-```sh
-$ ls ./runh-image/rootfs
-drwxr-xr-x 1 stefan stefan     128 May 24 12:27 .
-drwxr-xr-x 1 stefan stefan      96 May 24 12:27 ..
--rwxr-xr-x 1 stefan stefan 3651080 May 20 13:53 rusty_demo
--rwxr-xr-x 1 stefan stefan 2225868 May 19 22:50 hermit-loader
-```
-
-An OCI specification file is required to start the hypervisor within an isolated environment.
-The following commands generate a starter bundle for `rusty_demo`, create and start the container:
-
-```sh
-$ cd runh-image
-$ sudo runh --root /run/runh spec --bundle . --args /hermit/rusty_demo
-$ sudo runh --root /run/runh -l debug create  --bundle . runh-container
-$ sudo runh --root /run/runh -l debug start runh-container
+```Dockerfile
+FROM ghcr.io/hermit-os/hermit_env:latest
+COPY hermit-loader-x86_64 hermit/hermit-loader
+COPY httpd hermit/httpd
+CMD ["/hermit/httpd"]
 ```
 
-After a successfull test, the container can be deleted with following command:
+Afterwards, the container image can be created and pushed to the registry.
+The registery tag has to replace with the enduser registry.
 
 ```sh
-$ sudo runh --root /run/runh -l debug delete runh-container
+$ docker buildx build --tag ghcr.io/hermit-os/httpd:latest --push .
 ```
