How to install Docker CE on Wago devices.

Prerequisites for tutorial

• Wago PFC Generation 2 (e.g. 750-8212, 750-8213..)

2. Open WBM (Web Base Management) menu "Software Uploads".

3. Navigate to wago docker IPK. (e.g. docker_xx.xx.xx_armhf.ipk)
4. Then press "Install" button.

Move docker "DATA-ROOT" to the SD card.

Due to the lack of memory on the "home" partition it is interesting to move the docker "data-root" to an SD card. This approach offers the following advantages:

• positioning of more docker images on the PFC.
• any images / containers can be pre-installed by replacing the SD card.
• the physical portability of the images / containers increases.

Migration of docker "data-root"

1. Insert any SD card into the WAGO device (preferably WAGO SD card)
2. Open WBM (Web Base Management) menu "Mass Storage".

3. Select "Ext4" as file system type and assign a label for the SD partition (in our case "sd"). Then press the start button.

4. Stop running docker daemon.

        /etc/init.d/dockerd stop
   

5. Copy actual docker data root folder to sd card.

   cp -r /home/docker /media/sd/
   

6. Edit daemon.json and change docker "data-root" entry.

   vi /etc/docker/daemon.json or nano /etc/docker/daemon.json
   

4. Start docker daemon.

   /etc/init.d/dockerd start
   

5. Check docker functionality.

   docker info
   docker ps # to see all running container 
   docker images # to see all preinstalled images
