$ docker run hello-world Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/ $ docker images hello-world REPOSITORY TAG IMAGE ID SIZE hello-world latest 48b5124b2768 1.84 kB

awesome, my older brother
I get this when trying to run hello_world :
Unable to find image 'hello_world:latest' locally
Pulling repository docker.io/library/hello_world
C:\Program Files\Docker Toolbox\docker.exe: Error: image library/hello_world:latest not found.
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
Newbies not to understand anything with that example.
This example is not starting
i test install and configure docker on ubuntu on ibm power systems (linux on power). but i cannot start docker container on my systems. i found error detail as below.

Please help guide me
@sarjunkumar24391 do you have the output from when you try to run the container? Maybe something is wrong with your tags and it's still pulling the (unaltered) version from the repository instead of your local updated version.
@galope (maybe @alexus as well), RPi is an ARM architecture so the Docker-based apps have to be specifically packaged for that architecture (which the hello-world app isn't). You'll have to look for apps that are packaged for ARM. A good resource on the subject can be found here: http://blog.hypriot.com/getting-started-with-docker-on-your-arm-device/
I looked in the souce code and understood how the output is generated. but if i change the message in the hello.asm file and build a new automated image in docker hub, the message is not updated.... its still showing "Hello from Docker"...
SO HOW TO CHANGE THE MESSAGE CONTENT TO BE DISPLAYED
