Hello,

I wanted to know if there is a docker image for node-red dashboard available for the netPI?

These days it was time to think about Docker's multi-stage build feature and to provide an example of how it works.

Multi-stage builds are always then of any interest if applications need to be compiled first before getting them to an executeable state and as such be installed in the final container image ... but without all the necessary development tools, environments and compilers. This keeps the image small and away from all unnecessary data needed during compilation times only.

We found that the bluetooth registry on DockerHub would be best for a demonstration. Its Dockerfile contains two FROM commands the build process turns into two separate builds. Build STEP 1 creates a temporary container and compiles the bluetooth stack ... Build STEP 2 builds the final output container that is just copying the required outputs files of STEP 1.

Happy testing
Armin

We want to use the netPI in a network that uses proxy to connect to the internet.
Unfortunately I can't see any options where I can set the proxy settings.
Is there any way to setup the proxy connection?

Kind regards
Julian

End of the year 2018 company 3S released a new Service Pack Version SP14 of CODESYS Control V3.5.

We checked the netPI compatibility to this version and can confirm netPI's compatibility to this version.

Follow the README instuctions in the Repository and you will be fine.

Many of you know TeamViewer as remote support tool transmitting the screen of a remotely installed device to a local display over the Internet.

An Internet server between TeamViewer Host installed on the device and the TeamViewer Client as management console negotiates the traffic.

Today we released a TeamViewer example container that allows controlling a root login console session within the containers context.

Now it is easier than ever to log on to a remotely installed container application and manage and control it from outside.

The Docker Example container can be found here
The Build Script for the container can be found here

Please take a notice of TeamViewer's End User License Agreement Using it commercially is not for free.

While netPI's system time configured in the management web GUI

   

is passed to a container the timezone isn't. This is a Docker property.


In order to let a container have the correct timezone the environment variable TZ needs to be passed to the container when started. Otherwise the host time may differ from the container's time.

Here is an example how to set the variable:

   

Find there the list of possible timezones that can be configured

Available on netPI's home page in den download section.

For those who misplaced netPI's power connector ...

The type of connector is 3.81 mm centerline, Typ 369, terminal block with label 0/+24V.

We source the connectors through distributor Metz Connect at part number RP034xxVBLN with xx = 03 for three poles.

The manufacturer is RIA connect. The part number is P/N 313691xx with xx = 03 for three poles. Find the data sheet appended.

Thx
Armin

In the today's netPI system software release V1.1.5.0 we realized the following change:

• Possibility to shift away netPI's occupied HTTP/S ports 80 and 443 to any other port. This allows containers to take over those ports for own web applications listening on port 80/443.
  

netPI web GUI portainer.io offers a REST API to control netPI Docker daemon from remote. All that is needed is a HTTPS capable client that is addressing the API function over REST.

To understand how it works I created a new Node-RED (includes a HTTPS client) based flow. It is compatible with netPI software versions greater than >= 1.1.4.0. (for more details click HERE)
The flow includes a login, how to list containers, images, how to pull an image, create a container, start and stop it and ALSO how to push a container from netPI back to Docker registry.

Find appended the Node-RED flow you can test yourself. Open the flow file and copy its content to the clipboard and import it with "import/clipboard" in Node-RED using the top right menu pane. 

For older netPI software versions (< V1.1.4.0) you find the Node-RED flow HERE.
