Lab 1.3: Connect to f5-super-netops-container

In the previous lab we started the container image and were presented in a root user terminal. In order to use the container and its associated tools properly we will connect via SSH and/or HTTP.

Task 1 - Connect via SSH

To connect to the image via SSH we must use the published port specified in the docker run command. To review the command used to start the container was:

docker run -p 8080:80 -p 2222:22 -p 10000:8080 –rm -it -e SNOPS_GH_BRANCH=master f5devcentral/f5-super-netops-container:jenkins

This will publish the standard SSH service from TCP/22 to TCP/2222. In the case of the SSH service the following mapping applies:

localhost:2222 -> f5-super-netops-container:22

Execute below to SSH into the container includes the snops user with a password of default.

ssh -p 2222 snops@localhost

Note

The host SSH keys for our environment are regenerated each time the container boots, you may receive an error when trying to connect indicating the host key has changed. This error is safe to ignore in this case and can be resolved by removing the key from ~/.ssh/known_hosts. You can also configure your local SSH config by adding the following to ~/.ssh/config:

Host localhost
Port 2222
StrictHostKeyChecking no
UserKnownHostsFile /dev/null

Example output of connecting to the container:

$ ssh -p 2222 snops@localhost
Warning: Permanently added '[localhost]:2222' (ECDSA) to the list of known hosts.
snops@localhost's password:

                      | |  '------'''
                      | |                      _

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!
[snops@f5-super-netops] [~] $

Task 2 - Connect via HTTP

To connect to the image via HTTP we use the published port specified in the docker run command. To review the command used to start the container was:

docker run -p 8080:80 -p 2222:22 -p 10000:8080 –rm -it -e SNOPS_GH_BRANCH=master f5devcentral/f5-super-netops-container:jenkins

This will publish the standard HTTP service from TCP/80 to TCP/8080. In the case of the HTTP service the following mapping applies:

localhost:8080 -> f5-super-netops-container:80

Open Chrome on your Linux Jumphost and enter the URL:

http://localhost:8080/start

Task 3 - Connect via Jenkins

To connect to the image via Jenkins we use the published port specified in the docker run command. To review the command used to start the container was:

docker run -p 8080:80 -p 2222:22 -p 10000:8080 –rm -it -e SNOPS_GH_BRANCH=master f5devcentral/f5-super-netops-container:jenkins

This will publish the standard Jenkins service from TCP/8080 to TCP/10000. In the case of the Jenkins service the following mapping applies:

10.1.1.8:10000 -> f5-super-netops-container:8080

To connect to Jenkins open a web browser and enter the URL:

http://localhost:10000
