Docker first searched for the image we are trying to pull on your local machine but couldn’t find it. Try running the command docker run busybox echo "Hello world" and you should get a similar output:Īllow me to explain what running this command did for us. Now that you have Docker, you can run Docker commands using the Docker executable.īecause it’s common to start developing with a “Hello World!” program, let’s run a “Hello World!” container.
