To use the f5-super-netops-container you first need to install Docker Community Edition on your system.
Note
If you are using an F5 provided lab environment, Docker CE has already
been installed on the host named ‘Docker Server’. Please SSH
to that host a execute all docker commands there.
Please follow the instructions at https://docs.docker.com/engine/installation/ to install Docker CE.
Once you have completely installed and successfully run the hello-world
test you can continue to the next lab.
To test your setup with the hello-world container, you just need to run the
following command
docker run hello-world
Example output:
$ sudo docker run --rm hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/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

https://docs.docker.com/engine/userguide/
Note
The --rm option will delete the container as soon as it stops
running.
If you see this message: Cannot connect to the Docker daemon. Is the docker daemon running on this host? , it is likely that you don’t have enough privileges with your user, try to use sudo when executing docker commands.
If you want to remove the hello-world container, you can run the command
sudo docker rmi hello-world
If your container is running, you cannot remove the image.
You can issue the following commands in that case (this will stop ALL your container
instances):
sudo docker stop $(docker ps -aq)
