1 Deploy TOSCA Workloads in OpenStack via Stand-Alone TOSCAParser, Heat-Translator and Murano IBM Advisory Software Engineer OpenStack PTL Heat-Translator and Vahid Hashemian IBM Advisory Software Engineer OpenStack Core Heat-Translator and Sahdev Zala

2 Overview What is TOSCA? OASIS open standard specification that defines the interoperable description of services and applications of enterprise workloads hosted on the cloud. Enables interoperability and portability and automated management across cloud providers regardless of underlying platform or infrastructure. What is TOSCA-Parser? Parser for TOSCA Simple Profile in YAML What is Heat? Heat is an OpenStack orchestration engine that automates launching multiple composite cloud applications. What is Heat-Translator? An OpenStack project to map and translate non-heat (e.g. TOSCA) templates to Heat Orchestration Template (HOT). 2

3 Liberty Release: Heat-Translator Enhancements Project split Heat-Translator TOSCA-Parser First PyPI release of Heat-Translator and TOSCA-Parser OpenStackClient Plug-in New shell command TOSCA Cloud Service Archive (CSAR) support CSAR is a container in ZIP file format which includes TOSCA service template and artifacts required to deploy corresponding cloud application. Support for URL based template and CSAR Dynamic loading of custom types in translator 3

5 Translation with OpenStackClient or Shell OpenStackClient (OSC) openstack translate template --template-file /home/openstack/heat-translator/translator/tests/data/ tosca_helloworld.yaml --template-type tosca openstack help translate template Shell heat-translator --template-file=/home/openstack/heat-translator/translator/tests/data/tosca_helloworld.yaml -- template-type=tosca TOSCA YAML HOT YAML 5

6 Plan for Mitaka Release Cycle New PyPI release at a regular interval of around six weeks Bug fix PyPI releases as needed Development focus: development coverage for TOSCA Simple Profile in YAML 1.0 specification create CLI validator for TOSCA-Parser support for nested imports of TOSCA types mapping to SoftwareComponent resource in Heat enable deployment of translated stack via Heat-Translator support for storing TOSCA artifacts in Glance repository enhance TOSCA templates ecosystem TOSCA integration in Murano Application Catalog 6

7 Murano Overview OpenStack s application catalog that provides application packaging, deployment, and lifecycle management. Uses the notion of environments as collections of one or more application packages that can be deployed and managed together. Supports HOT and MuranoPL for application definitions. For HOT templates, Murano starts by creating a package out of the template that will be imported into the application catalog. We are expanding Murano and adding TOSCA support by leveraging Heat-Translator and TOSCA-Parser. 7

8 Murano Package Creation and Import: HOT An archive package is created from the input HOT template. It is then imported into the application catalog (via command line or UI). 8

9 Murano Package Creation and Import: TOSCA An archive package is similarly created from a CSAR archive. This step involves validating the CSAR. It is then imported into the application catalog (via CLI or Horizon). 9

10 Murano Package Creation and Import After the import, the packages will be available in Murano s Application Catalog. CSAR based packages will be distinguishable by their default logo. 10

11 Murano Deployment: HOT vs. TOSCA HOT packages are deployed by Murano. TOSCA CSAR packages can be deployed by Murano or Heat- Translator. 11
