Docker -Test your installation

 

Test your installation

1. Open a terminal window (Command Prompt or PowerShell, but not PowerShell ISE).

2. Run docker --version to ensure that you have a supported version of Docker:

   > docker --version
   
   Docker version 20.03.1
   

3. Pull the hello-world image from Docker Hub and run a container:

   > docker run hello-world
   
   docker : Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   1b930d010525: Pull complete
   Digest: sha256:c3b4ada4687bbaa170745b3e4dd8ac3f194ca95b2d0518b417fb47e5879d9b5f
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   ...
   
   

4. List the hello-world image that was downloaded from Docker Hub:

   > docker image ls
   

5. List the hello-world container (that exited after displaying “Hello from Docker!”):

   > docker container ls --all
   

6. Explore the Docker help pages by running some help commands:

   > docker --help
   > docker container --help
   > docker container ls --help
   > docker run --help
