====== Editing Profile Resources ======

==== Introduction ====
\\ 
<color #ed1c24>This article is really only applicable in PoD per Service deployments</color>
\\ 
\\ 
IPHE encoding profiles (except the one just called 'encoding') have a CPU limit that is defined in the yaml code. Each encoding profile type has a different value. However this value may not be very optimised for all servers, depending on the CPU / RAM configuration a server has.
\\ 
\\ 
For this reason we will probably want to change the default values for a particular server to optimise the number of vCPUs that are allocated to an encoding PoD.
\\ 
\\

==== Download an existing encoding profile ====
\\ 
Open the MDT application (https://ipaddress:30443) and login using mdt-admin / changeme.
\\ 
\\ 
{{ :profiles.png?900 |}}
\\ 
\\ 
Now look for an appropriate encoding profile to download (I normally take encoding-hd) and select the 'export profile' button.
\\ 
\\ 
{{ :export_profile.png?900 |}}
\\ 
\\ 
The encoding profile (a .yaml file) will now download. 
\\ 
\\ 

----

==== Editing the encoding profile ====
\\ 
Open the .yaml file (preferably in an editor that properly supports .yaml file formats (not notepad)) and save it to a new filename. 
\\ 
\\ 
The part of the encoding profile that we are interested in starts with resources: If the file you downloaded does not have this section, download a difference default encoding profile (encoding-hd for example).
\\ 
<code yaml>
      resources:
        requests:
          cpu: 9
</code>
\\ 
\\ 
Below is the updated code block where we not only specify the vCPU request, we can also specify a limit that the PoD can go up to in terms of vCPU and memory.
\\ 
\\ 
<code yaml>
      resources:
        requests:
          cpu: 7
          memory: 4Gi
        limits:
          cpu: 15
          memory: 10Gi
</code>
\\ 
You will have to edit the file and upload it with a new set of name(s). Please [[duplicating_encoding_profiles|*** here ***]] for more instructions regarding this.
