Images can be found on Docker Hub.

https://hub.docker.com/search?q=&type=image

To see images available we can use the terminal or Portainer.

$ docker images
REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE
jorgenlarsen/mariadb10.3   rpi                 09f38af10d8f        2 weeks ago         316MB
portainer/portainer-ce     latest              5526251cc61f        7 weeks ago         163MB

Or use Portainer:

Please note that images are dependent on:

• Operative system / version
• CPU:
  • Intel
  • ARM
  • AMD
  • PPC

Everything SHOULD be tagged accordingly on Docker Hub. Noting: “should”

During the make of the site I have experienced problems by pulling images able to run on RaspBerry Pi.

If you get this message trying to run an image:

standard_init_linux.go:211: exec user process caused “exec format error”

You are sure to have pulled an image not able to run on your system.

To check an image for Operative System and CPU combability use the Docker command:

$ docker inspect IMAGE ID

Look for the text: “Achitechture”
