[Story]: Validate Use-Cases

[andrewballantyne]

Goal

Validate OSSM use-case scenarios

Dependency issue

• [Feature Request]: Support use of Service Mesh for routing #1087

Itemized goals

Here are some high level test scenarios — we’ll really need QE to spend some time thinking about these, but these are a good start. Vet for what you think it should do. Log bugs for issues.

1. Fully Disabled

   Supported, noop

   • Pre-reqs
     • Disabled feature flag
     • No Service Mesh installed
   • Steps
     • Create DS Project; Expect: No enabled state annotation
     • Create Workbench; Expect: Route to work with oauth proxy
2. Flag Disabled

   not valid -- Service Mesh enables feature flag

   • Pre-reqs
     • Disabled feature flag
     • Install Service Mesh
   • Steps
     • Create DS Project; Expect: Project has annotations
     • Create Workbench; Expect: Route to work with oauth proxy
3. Install Service Mesh - fresh path

   supported, standard flow

   • Pre-reqs
     • No projects
     • Install Service Mesh
     • Enabled feature flag
   • Steps
     • Create DS Project; Expect: State flags enabled
     • Create Workbench; Expect: Route to use Istio proxy
4. Install Service Mesh - post DS Projects install

   needs docs, looking for dashboard label; problem for OpenShift Projects

   • Pre-reqs
     • At Start: No Service Mesh installed
     • Have two projects
       • A: service-mesh = true — does not have annotations
       • B: service-mesh = false — does not have annotations
   • Steps
     • Install Service Mesh, once finished:
     • Expect: project A to migrate on install & new workbenches to use Istio proxy
     • Expect: project B to NOT migrate on install (no annotation change); new and existing workbenches use oauth proxy
5. Test Upgrade

   Supported as scenario 4 for Data Science projects (needs docs)

   • Do scenario 2 (flag disabled) again & follow up with:
     • Enable Feature Flag
     • Re-rollout pods (operator will do this when image references change)
6. Flag Enabled / No Service Mesh

   Remove flag, not a scenario anymore

   • Pre-reqs
     • Enabled feature flag
     • No Service Mesh installed
   • Steps
     • Create DS Project; Expect: No enabled state annotation
     • Create Workbench; Expect: Route to use oauth proxy

Aspects continued elsewhere

• [Andrew] Ask the Operator folks about reading DSCI and getting service mesh status
  • Is there ever a reason to not use service mesh in the UI while it is installed
