Hi community,

maybe one of you have an nice idea how to solve my problem.

I want to transfer a logo (jpg) over the ansible tower api “api/v2/settings/ui/”.

`

- name: Import over API  
uri:  
url: “{{ api\_url }}”  
user: “{{ username }}”  
password: “{{ password }}”  
method: PATCH  
body: “{{ lookup(‘template’, ‘logo.j2’) }}”  
force\_basic\_auth: yes  
body\_format: json  
status\_code: “200,201”  
validate\_certs: no  
`

The template “logo.j2” looks like this:

`{ "CUSTOM_LOGO": "data:image/jpeg;base64,/9j/4AAQSkZ.......AKKKKAP/2Q==" }`

To get the base64 string I uploaded the image with the Ansible-Tower GUI and call the API GET method. An alternative is to use this website: [https://www.base64-image.de/](https://www.base64-image.de/)

**My goal is to encode the image with ansible or with a jinja2 filter like this:**

`  
{  
“CUSTOM\_LOGO”: “{{ lookup(‘file’, ‘image.jpg’) | b64encode }}”  
}

`

Thanks for your support.

Alexander

Hi Kai,

its not an Ansible Tower question. Is general Ansible.

I want to encode a jpg image to base64 to use this image in a JSON object.

This JSON object I want to transfer as body with the Ansible module uri.

Thanks,

Alexander

I'm sorry, probably read it to fast and jumped to conclusions.

The b64decode in Ansible can only handle plain text/ascii, for binary date it gives corrupt result so my hunch that b64encode does the same and you need to use base64 command with command/shell module.

Hi,

here is my solution:

`

- name: Get base64 string  
shell: “/usr/bin/base64 {{ role\_path }}/files/{{ ansible\_tower\_logo\_filename }} | tr -d ‘\n’”  
delegate\_to: 127.0.0.1  
register: base64\_string

- name: debug base64 string  
debug:  
var: base64\_string  
verbosity: 3

- name: Show template  
debug:  
msg: “{{ lookup(‘template’, ‘ui.j2’) | to\_nice\_json }}”  
verbosity: 2

- name: Import over API  
uri:  
url: “{{ api\_url }}”  
user: “{{ ansible\_tower\_inventory\_admin\_username }}”  
password: “{{ ansible\_tower\_inventory\_admin\_password }}”  
method: PATCH  
body: “{{ lookup(‘template’, ‘ui.j2’) }}”  
force\_basic\_auth: yes  
body\_format: json  
status\_code: “200,201”  
validate\_certs: no  
`

Here the content of the file ui.j2:

`{ "CUSTOM_LOGO": "data:image/jpeg;base64,/{{ base64_string.stdout }}", "CUSTOM_LOGIN_INFO": "{{ ansible_tower_login_info_message | default('') }}" }`

Thanks for your help
