Problem about Docker, Node-red
I am looking for a way to include docker in PLCnext to take advantage of node-red, however, I followed the manufacturer's instructions, they require an SD card, I installed it myself in case I don't have it, it's not possible, Can anyone give me a way to install docker in PLC without SD card? I thank you very much and look forward to reply

Hello tienanhpham9910,
If you are using the PLCnext controller AXCF2152 without SD Card you have only 512MB internal storage (I assume you are using AXCF2152 controller). You can install the App "balenaEngine-DockerForIOT-ARM" (PLCnext Store | balenaEngine-DockerForIOT-ARM) on the PLC via WBM. And then try to install/run the docker image using balena engine, see Example in chapter "Download an image to the controller" in PLCnext/Docker_GettingStarted: HowTo get a Docker like container engine (Balena-Engine) running on PLCnext Control. (github.com).
I think the following description can also be helpful: Node RED on Docker - Raspberry Valley (raspberry-valley.azurewebsites.net)

Thank you for your help, I was about to download the balena engine when I encountered this problem, it seems that some apps are only downloaded in Europe, how to download, thank you.
Can you give me the info about your country name, please?
Thanks!
i live in Da Nang, Viet Nam , thanks for your require !
i also happened capture screen from my phone , it show the app is availble on US Store , not World Store
Hello,
when the app is not available in your country, you can still install balena on your AXC manually. There is a script and a detailed description on github GitHub - PLCnext/Docker_GettingStarted: HowTo get a Docker like container engine (Balena-Engine) running on PLCnext Control.
Thanks all , i transfered my ID from Viet Nam to Germany and it worked !

I am downloading docker, what should I do if I have a problem like this? I don't know if my kit can connect to the internet? I followed the steps on github and it reported this, can you help me?
Hello tienanhpham9910,
each developer decides in which regions his app is offered.
My suggestion is that you ask the developer if they can publish this app in all regions.
To contact them, use the "Contact Developer" button on the app details page in the store.
If you have downloaded the *.app container from the store, you can install and start it with the WBM of the device.
I don't know if my kit can connect to the internet?
If your device cannot to the internet, then it will probably be difficult to develop OCI applications on the device, since (for example) it will not be able to pull images from web-based repositories. I recommend setting up the device to connect to the internet, at least during the development stage of the project.
Has the way to fix this error ?
i do step by step on slide from page 7 to 21
PowerPoint Presentation (codeandcompile.com)
I have asked someone from your local Phoenix Contact office to get in touch and help get your PLC connected to the internet.
thank you @Martin PLCnext Team , when will people respond? I tried all the ways, even in PLCnext run time, it doesn't work
Please be sure of the ip adress for your subnet:
Standard IP adress: 192.168.1.10 -> Must be changed to your subnet
Gateway: -> Must be changed to the ip from your router
DNS: 8.8.8.8, maybe the google dns is not available, switch to something else (normally your router works)
You can change the setting in WBM or with console in /etc/network/interfaces
i checked many times, it doesn't work @jan.mueller@phoenixcontact.de
I sent you an email a few days ago, asking for information about your network configuration, which will help us to help you get your PLC connected to the internet. Please reply to that email with the requested information.
Sorry Mr.Martin , my partner in my team also reply your email, i forward the message for him , you can contact with my friend because the PLCnext kit is staying at his home , thanks
