Externalizer in AEMaaCS

[RadhaKrishna]

Hi All,

Environment Variables:

• AEM_EXTERNALIZER_PREVIEW
• AEM_EXTERNALIZER_PUBLISH
• AEM_EXTERNALIZER_AUTHOR

{
   "externalizer.domains": [
      "local $[env:AEM_EXTERNALIZER_LOCAL;default=http://localhost:4502]",
      "author $[env:AEM_EXTERNALIZER_AUTHOR;default=http://localhost:4502]",
      "publish $[env:AEM_EXTERNALIZER_PUBLISH;default=http://localhost:4503]",
      "preview $[env:AEM_EXTERNALIZER_PREVIEW;default=http://localhost:4503]"
   ]
}

When I checked with our admin team, they informed there are no environment variables defined in the cloud manager. 

1. What are the values of the environment variables in the default configuration, when there is no custom configuration defined.
2. How it is calculated?

Thanks,
RadhaKrishna

Hi @RadhaKrishna ,

In your provided configuration snippet, the externalizer domains are set with environment variables for different environments: local, author, publish, and preview. However, if these environment variables are not defined, default values are provided as fallbacks.

The default values provided in your configuration snippet are:

• local: http://localhost:4502
• author: http://localhost:4502
• publish: http://localhost:4503
• preview: http://localhost:4503

These defaults are specified using the $[env:VARIABLE_NAME;default=default_value] syntax. If an environment variable is not defined (VARIABLE_NAME), the default value (default_value) will be used instead.

So, in the absence of custom configurations or explicitly defined environment variables, the values provided above would be used as defaults for the corresponding externalizer domains in your AEMaaCS instance. These values are determined by the configuration set by the AEMaaCS platform.

We would need to create these environment variables manually.

The AEMaaCS doesn't know the client-facing domain OOTB. 

Once you have finalized the domain create these variables with proper Domain value in Cloud manager.

Example: if your dev-publish domain is abc. Register  http://abc.com for AEM_EXTERNALIZER_PUBLISH for Dev environment in Cloud manager
