Issue 113: Make changes needed to successfully register deploy module.

[kaladay]

resolves #113

Changes

Prepend 'camunda.' to each permission.

• This gets the permissions structure to be compliant by having the module name as part of the permission name.
• Without this, potential cross-module conflicts exist.

The provides dependencies are for individual module parts and not the entire module. Change the behavior to use the individual mod-workflow parts as a dependency.

Remove mod-camunda from the context path. Having mod-camunda in the context path is preventing proper deployment in OKAPI.

Local Deployment Test Process

This assumes proper login and other relating configuration. This uses {{}} syntax to loosely represent variables. Consider using the stripes-cli to perform the appropriate tasks.

1. Make sure to start up a local docker or vagrant version of folio, like the FOLIO Nolana vagrant. For example, the OKAPI login using stripes-cli might look like this:

   stripes okapi login diku_admin --okapi http://127.0.0.1:9130 --tenant diku

2. Perform the appropriate maven packaging of the project.
3. Spin up a local instance of mod-workflow, such as mvn spring-boot:run, java -jar ..., or an appropriate docker command.
4. A POST request to {{okapi_url}}/_/proxy/modules in order to register the module. Make sure to use the build ModuleDescriptor.json as the payload body, generally found under service/target/.
5. A POST request to {{okapi_url}}/_/discovery/modules. Rather than using the DeploymentDescriptor.json generally found under service/target/, use the following as the payload body.

   {
   "srvcId": "mod-workflow-{{mod_workflow_version}}",
   "instId": "mod-workflow-{{mod_workflow_version}}",
   "url": "{{mod_workflow_url}}"
   }

   The {{mod_workflow_url}} in particular needs to point to an address of the locally running mod-workflow that the local FOLIO instance can access.

6. A POST request to {{okapi_url}}/_/proxy/tenants/{{tenant_name}}/modules, using the following as the body payload:

   {
   "id": "mod-workflow-{{mod_workflow_version}}"
   }

There may be permissions problems, in which case, they could be resolved using the stripes-cli. Example:

echo "okapi.proxy.modules.post" | stripes perm assign --okapi http://127.0.0.1:9130 --user diku_admin --tenant diku

To disable the module, a DELETE to {{okapi_url}}/_/proxy/tenants/{{tenant_name}}/modules/mod-workflow-{{mod_workflow_version}}.

To undeploy the module, a DELETE to {{okapi_url}}/_/discovery/modules/mod-workflow-{{mod_workflow_version}}.
