Virtual Servers template?

Hello All,

Is there a way to create a Virtual Servers “template” with predefined settings on a BIG-IP F5 load balancer? We create VS almost every day for our clients and would help if we could setup a VS from a template to make our life a bit easier.

The concept “VS template” in F5 is known as iApp. I give you some doc.

Another way to standardize your deployments is to use Ansible that gives you the ability to create templates that you could apply in your environment later on. Some doc.

Thanks for that. Is there a easy way where I could take an exisiting Virtual server setup and convert into an iApp?

You can take the HTTP iApp template and try to rewrite those part that you would like to customise.

BTW, I share with you a list of other supported iApps

You can find the last version of each one in F5 downloads.

Thanks Dario for all the information and links. There is too much information and unfortunately I’m not a programmer.

Could someone assist in helping me with creating a simple iApp template to deploy Virtual Servers that contains the following settings? I would greatly appreciate it.

[General Properties]

Type: Standard

Source: 0.0.0.0/0

Destination: Type HOST

Address (**IP user input**)

State: Enabled

[Configuration (BASIC) all the other options should be set to DEFAULT settings]

Protocol: TCP

HTTP Profile: http_20

You can use CLI to create the VS (replace “<…>” fields with the correct value).

tmsh create ltm virtual <VS_NAME> \
destination <VS_IP>:443 \
profiles add { tcp http_20 <CLIENTSSL_PROFILE> } \
vlans replace-all-with { Internal Web } vlans-enabled \
snatpool Prod \
pool Webfarm_pool \
persist replace-all-with { cookie_20 } \
rules { httpTest_irule1 httpTest_irule2 httpTest_irule3 }

Finally you have to save the config from running-config to startup-config.

tmsh save sys config

Dario.
