9.2 Container for netPI: Examples
The device contains a Docker host enabling the deploy of own Edge
automation applications to execute them in safe containers. Since netPI is
a Docker host only, you cannot build images on-board. netPI's security
concept prohibits SSH servicing and hence you cannot get access to
"Docker build commands". Since containers run the same on any
compatible hardware use a Raspberry Pi 3 instead for image development.
Buying the consumer Pi for a low price is a riskless invest for getting
familiar with Docker, making usability and performance tests of applications
before moving them onto the professional netPI.
Docker hub is an Internet platform to share container images with co-
workers, customers and the Docker community. For netPI there is a registry
as well providing you examples for immediate use, such as the Thing Editor
Node-RED or a HDMI desktop environment and many more. Use them also
as templates for your own ideas when starting creating own images.
