Input output mapping for templates and Helm charts

Mapping procedure in the Managed services user interface and their input output formats.

Template / Helm input parameters
Template / Helm output parameters
For service instance level parameter details and service instance level parameters in Error flow, see Service instance level parameters.

Template / Helm chart input parameters

Representing input parameters and attributes of an activity within another activity.

Note: The templates word in the syntax is used for both template and helm activities.

If your source parameter is defined in the input parameters section of an activity, then use the following format to call its value within another activity:

${activity.id.paramname}

Examples:

For example, Apache Tomcat on a single virtual machine template activity has TomcatNode01-mgmt-network-public parameter defined in the INPUT PARAMETERS section. Use the following format to call its value within another activity:
```
 ${templates.tomcat019453ac.TomcatNode01-mgmt-network-public}
```
or
```
 ${templates.tomcat019453ac.input.TomcatNode01-mgmt-network-public}
```
Where tomcat019453ac is the activity Id.

For example, mapping the output of IPAM template as an input to Oracle Database 12c Enterprise Edition on a single virtual machine template:

 OracleDBNode01_dns_suffixes": "${templates.ipam1467a9b92b6c.output.ipam_result_domain_list},
 OracleDBNode01_domain": "${templates.ipam1467a9b92b6c.output.ipam_result_domain_str},
 OracleDBNode01-name": "${templates.ipam1467a9b92b6c.output.ipam_result_host},
 OracleDBNode01_ipv4_address": "${templates.ipam1467a9b92b6c.output.ipam_result_ip_address},

Where

OracleDBNode01 is the ID ofOracle Database 12c Enterprise Edition on a single virtual machine template.

ipam1467a9b92b6c is the ID of IPAM template.

The sample snippet of Service Composition Language wherein the output of one template activity is mapped as input into another template activity:

The following input parameters are common for all template/Helm activities:

Format:

${templates.<id>.<attribute name>}

${templates.<id>.instance_name} \\ Name of the instance
${templates.<id>.template_name} \\ Name of the template activity
${templates.<id>.template_version} \\ Version of a template activity
${templates.<id>.title} \\ Title of a template activity
${templates.<id>.stack_id} \\ Stack id of an activity

Template / Helm output parameters

Representing output parameters and attributes of a template / helm activity within another activity.

Note: The templates word in the syntax is used for both template and helm activities.

Use the following format for a specific template/helm activity:
- If you want to map your parameter to the output parameters of another template/helm activity, then prefix the word "output" when you reference it in the value field.
```
${activity.id.output.paramname}
```
  The param_name is the name of the parameter that is returned by a particular template activity or helm activity. It depends on the template definition for terraform templates, and for helm chart, it depends on the parameters defined in IBM Cloud Pak® for Multicloud Management.
  
  For example, Apache Tomcat on a single virtual machine template activity has TomcatNode01_ip defined in the OUTPUT PARAMETERS section. Use the following format to call its value within another activity:
```
${templates.tomcat019453ac.output.TomcatNode01_ip}
```
  Where, tomcat019453ac is the template activity Id and TomcatNode01_ip is the parameter.

The following output parameters are common for all template/helm activities:

Format:

${templates.<id>.<attribute name>}

${templates.<id>.action} : **`CREATE`** / **`DELETE`**
${templates.<id>.status} : **`SUCCESS`** / **`IN_PROGRESS`** / **`FAILED`**
${templates.<id>.status_message} :  additional message for the status
${templates.<id>.stack_message} : template execution stack logs (from IAAS)
${templates.<id>.stack_error_message} : template error message (from IAAS)
${templates.<id>.created_at} : template created at. (from IAAS)
