In this lab we will use the docker cli tools to obtain and start the
f5-super-netops-container image.
Perform the following steps to complete this task:
Open a Command Prompt
Note
If you are using an F5 provided lab environment please SSH to the ‘Docker Server’ host and execute the following commands.
Execute docker pull f5devcentral/f5-super-netops-container:base
Example output:
$ docker pull f5devcentral/f5-super-netops-container:base

To start the container we will execute the command:
docker run -p 8080:80 -p 2222:22 -it f5devcentral/f5-super-netops-container:base
The -p option publishes a L4 port from the container to the host. For
example the -p 8080:80 option will redirect port 8080 on the host system
to port 80 in the container.
The -it option will make the session interactive and allocate a pseudo-TTY
The f5devcentral/f5-super-netops-container:base option is the name
associated with the image we obtained in Task 1.
Perform the following steps to complete this task:
Execute docker run -p 8080:80 -p 2222:22 -it f5devcentral/f5-super-netops-container:base
Note
The image requires Internet connectivity to download the latest versions of tools and documentation. Please ensure you have proper connectivity from your host prior to starting the image. If you need to use a proxy please refer to the documentation at https://docs.docker.com
The image will now start and load resources from the Internet. This process
may take a while depending on the speed of your connection. When the startup
process is complete you will be presented with a root user prompt. You
can interact with the image with standard Linux commands. In the next lab
we will connect to the image via SSH and HTTP.
Example startup output:

Welcome to the f5-super-netops-container. This image has the following
services running:
SSH tcp/22
HTTP tcp/80
To access these services you may need to remap ports on your host to the
local container using the command:
docker run -p 8080:80 -p 2222:22 -it f5devcentral/f5-super-netops-container:base
From the HOST perspective, this results in:
localhost:2222 -> f5-super-netops-container:22
localhost:8080 -> f5-super-netops-container:80
You can then connect using the following:
HTTP: http://localhost:8080
SSH: ssh -p 2222 snops@localhost
Default Credentials:
snops/default
root/default
Go forth and automate!
(you can now detach by using Ctrl+P+Q)
[root@f5-super-netops] [/] #
When running containers it’s important to understand that it will exit if the
foreground process (in this case the shell) exits. For example, if you typed
the exit command in the running container it will shutdown. In order to
avoid this you should detach from the container once it has completed booting.
You can still perform functions by using SSH to access the container as
explained in the next lab.
Enter Ctrl+P+Q in the running TTY.
Example output:
[root@f5-super-netops] [/] #
[root@f5-super-netops] [/] #
[root@f5-super-netops] [/] # <enter Ctrl+P+Q>
hostname:~ user$
Verify the container is still running by entering docker ps
Example output:
hostname:~ user$ docker ps
