+# docker-noflo-runtime-js
+This is the source to build a docker container for [noflo-nodejs](https://github.com/noflo/noflo-nodejs).
+There shall be an additional version for X86 in addition to the current ARM (Raspberry Pi) version.
+
+## Very short: How do I use it?
+Install docker engine on a Raspberry Pi and then run 
+
+    docker run -d -e "SEJNUB_FLOWHUB_USERID=<user-id>" -e "SEJNUB_NOFLO_RUNTIME_HOST=<host>" -e "SEJNUB_NOFLO_RUNTIME_SECRET=<secret>" -e "SEJNUB_NOFLO_RUNTIME_LABEL=<label>" --name nojs -p 3569:3569 sejnub/noflo-runtime-js:rpi-latest 
+
+and now the longer version:
+
+
+## Status and rights
+Seems to be working. 
+Totally free to use by everyone.
+
+
+## Tags
+  * **``rpi-latest``**  Latest version for Raspberry Pi
+
+
+## Clean up before build
+    docker rm $(docker ps -a -f status=exited -q)
+    docker rmi $(docker images -f dangling=true -q)
+    docker volume rm $(docker volume ls -f dangling=true -q)
+
+
+## Build
+
+    cd ~; rm -rf docker-noflo-runtime-js; git clone https://github.com/sejnub/docker-noflo-runtime-js.git
+    cd ~/docker-noflo-runtime-js; docker build --no-cache=false -t sejnub/noflo-runtime-js:rpi-latest .
+
+
+## Push images to https://hub.docker.com
+
+If you are not sejnub you have to retag the images to your username at dockerhub and use those new tags. The following commands use the authors tags.
+
+Log into dockerhub and push the images with
+
+    docker login
+    docker push sejnub/noflo-runtime-js:rpi-latest
+
+
+## Create env-file (optional)
+You have to create an env-file `/usr/local/etc/sejnub-credentials.env` with the following content
+
+    # noflo-runtime-js
+    SEJNUB_FLOWHUB_USERID=<your-user-id-that-you-got-from-flowhub>
+    SEJNUB_NOFLO_RUNTIME_HOST=<ip-or-hostname-which-can-be-used-to-access-the-runtime>
+    SEJNUB_NOFLO_RUNTIME_SECRET=<freely-choosable-secret-string>
+    SEJNUB_NOFLO_RUNTIME_LABEL=<freely-choosable-label>
+
+
+## Run interactively
+
+Depending on if you created the env-file you run one of the following commands
+
+    docker rm -f nojs; docker run -it -e "SEJNUB_FLOWHUB_USERID=<user-id>" -e "SEJNUB_NOFLO_RUNTIME_HOST=<host>" -e "SEJNUB_NOFLO_RUNTIME_SECRET=<secret>" -e "SEJNUB_NOFLO_RUNTIME_LABEL=<label>" --name nojs -p 3569:3569 sejnub/noflo-runtime-js:rpi-latest /bin/bash
+    docker rm -f nojs; docker run -it --env-file /usr/local/etc/sejnub-credentials.env --name nojs -p 3569:3569 sejnub/noflo-runtime-js:rpi-latest /bin/bash
+
+
+## Run for production
+
+Depending on if you created the env-file you run one of the following commands
+
+    docker rm -f nojs; docker run -d -e "SEJNUB_FLOWHUB_USERID=<user-id>" -e "SEJNUB_NOFLO_RUNTIME_HOST=<host>" -e "SEJNUB_NOFLO_RUNTIME_SECRET=<secret>" -e "SEJNUB_NOFLO_RUNTIME_LABEL=<label>" --name nojs -p 3569:3569 sejnub/noflo-runtime-js:rpi-latest 
+    docker rm -f nojs; docker run -d --env-file /usr/local/etc/sejnub-credentials.env --name nojs -p 3569:3569 sejnub/noflo-runtime-js:rpi-latest
+
+or you can also use a mix like e.g.
+
+    docker rm -f nojs; docker run -d --env-file /usr/local/etc/sejnub-credentials.env -e "SEJNUB_NOFLO_RUNTIME_LABEL=<label>" --name nojs -p 3569:3569 sejnub/noflo-runtime-js:rpi-latest
+
+
+
+The specified port on the host $SEJNUB_NOFLO_RUNTIME_HOST must be accesible from the browser.
