Overview
Catalog Recipes are JSON configuration entries in catalogs collection in core provision database; each catalog represents a recipe to deploy an nginx - service - daemon - mongo - elasticsearch - nodejs service or any custom type.
Once a catalog recipe is created, you can then use it in the Clouds & Deployments section to deploy your services.

Service Catalog Recipe
The following recipe allows the deployment of SOAJS services and controllers
Daemon Catalog Recipe
The following recipe allows the deployment of SOAJS daemon
Nginx Catalog Recipe
The following recipe allows the deployment of an Nginx Container.
Mongo Catalog Recipe
The following recipe allows the deployment of a Mongo Container.
Elasticsearch Catalog Recipe
The following recipe allows the deployment of an ElasticSearch Container.
NodeJs Catalog Recipe
The following recipe allows the deployment of a NodeJS Container.
Environment Variables
The catalog recipe provide the ability to send environment variables to the service container(s) you are deploying.
These environment variables are classified to 3 categories:
Static
This environment variable provided a static value of type string.
"NODE_ENV": { //variable name in your code
"type": "static", //type is static
"value": "production" //value is the word production
}
Computed
This environment variable is computed by SOAJS then assigned before passing the recipe to the deployer to deploy the service container(s).
The full list of supported computed environment variables is found on this page and detailed in depth, Click here to see the list.
"CONTROLLER_IP": { //variable name in your code
"type": "computed", //type is computed
"value": "$SOAJS_NX_CONTROLLER_IP_N" //the variable that SOAJS should match from its list and replace here
}
When you deploy a service, you pick the catalog recipe. SOAJS will then load the list of its environment variables and match them to all the computed variables of your recipe.
The above will result in creating an environment variable called CONTROLLER_IP whose value is 127.0.0.1 for example.
After your deploy your service, if you click on the inspect operation from maintenance operations, you will find that the value of your computed variable is now:
"CONTROLLER_IP": { //variable name in your code
"type": "computed", //type is computed
"value": "127.0.0.1" //if the value of $SOAJS_NX_CONTROLLER_IP_N is 127.0.0.1 in SOAJS for example, then your env variable will now have that value
}
User Input
This environment variable depicts that the user should provide its value while deploying a service.
This means that when you are deploying a new service, if you pick the catalog recipe, SOAJS Dashboard will create new inputs for each environment variable whose type is userInput.
Provide the value of these variables and click deploy.
"MY_ENV": { //variable name in your code
"type": "userInput", //type is userInput
"label": "My Custom User Input Variable", //label to show above the input when attempting to deploy using this recipe
"default": "something", //default value of the input that shows up when attempting to deploy using this recipe
"fieldMsg": "Enter the value of your custom environment variable." //descriptive message that below the input that shows up when attempting to deploy using this recipe
}
