pickup hostname and create self signed certificate

[visar]

Hello Experts,

i have working command for creating self signed certificate for IHS server's .kdb file and i was trying to use the same command through ansible. Here my aim is that ansible should detect the hostname of application servers and should use that name for the "-dn" of the command.

Below is the working command 

[root@myhost bin]# ./gskcmd -cert -create -db /opt/myapp/key.kdb -label IHS -expire 3650 -size 2048 -dn "CN=myserverFQDN" -default_cert yes -pw password

but below is my play and its giving syntax error

---

- name: installation

  hosts: IHS

  tasks:

    - name: get hostname

      shell: echo $HOSTNAME

      register: hostname

    - name: create self signed certificate for IHS

      command: /opt/myapp/bin/gskcmd -cert -create -db /opt/myapp/key.kdb -label IHS -expire 3650 -size 2048 -dn "CN={{ hostname}}" -default_cert yes -pw password

hosts: IHS
gather_facts: yes

  tasks:
 
    - name: Create Self Signed Certificate for IHS

      command: /opt/myapp/bin/gskcmd -cert -create -db /opt/myapp/key.kdb -label IHS -expire 3650 -size 2048 -dn "CN={{ ansible_fqdn }}" -default_cert yes -pw password
