Looking good! LMK any thoughts on the API path comments. This is a good sized unit of work to land so definitely save the CLI changes for another PR. Feel free to ping me when the TODOs are tidied up (or earlier if you prefer) and I can take another more detailed pass.

Mostly nits and follow ups. The only substantive comments are to replace float with integer types throughout (unless I'm missing something) and deleting some APIs that relate to backwards compatibility baggage from the plugin catalog. Otherwise, LGTM!

The implementation doesn't belong in this PR, but I think we should handle this case higher up in the call stack - i.e. in the delete API handler function.

I had a bit of struggle parsing the Data back to runtimes after changing to store the returned runtimes in Data as []map[string]any

vault/vault/logical_system.go

Lines 835 to 871 in 9e59d84

var data []map[string]any

for _, runtimeType := range consts.PluginRuntimeTypes {

if runtimeType == consts.PluginRuntimeTypeUnsupported {

continue

}

configs, err := b.Core.pluginRuntimeCatalog.List(ctx, runtimeType)

if err != nil {

return nil, err

}

if len(configs) > 0 {

sort.Slice(configs, func(i, j int) bool {

return strings.Compare(configs[i].Name, configs[j].Name) == -1

})

for _, conf := range configs {

data = append(data, map[string]any{

"name": conf.Name,

"type": conf.Type.String(),

"oci_runtime": conf.OCIRuntime,

"cgroup_parent": conf.CgroupParent,

"cpu": conf.CPU,

"memory": conf.Memory,

})

}

}

}

resp := &logical.Response{

Data: map[string]interface{}{},

}

if len(data) > 0 {

resp.Data["runtimes"] = data

}

return resp, nil

}

like in the example Response below.

{ "request_id": "e93d3f93-8e4f-8443-a803-f1c97c123456", "data": { "runtimes": [ { "name": "gvisor", "type": "container", "oci_runtime": "runsc", "cgroup_parent": "/cpulimit/", "cpu": 1, "memory": 10000 }, { "name": "foo", "type": "container", "oci_runtime": "otherociruntime", "cgroup_parent": "/memorylimit/", "cpu": 2, "memory": 20000 } ] }, "warnings": null, "auth": null }

I attempted use mapstructure.Decode different ways to parse Response.Data["runtimes"]
but TestList* sys_plugins_runtimes_test.go couldn't pass asOCIRuntime:"", CgroupParent:"" weren't parsed correctly.

=== RUN TestListPluginRuntimeTyped/container sys_plugins_runtimes_test.go:135: expected: &api.ListPluginRuntimesResponse{Runtimes:[]api.PluginRuntimeDetails{api.PluginRuntimeDetails{Type:"container", Name:"gvisor", OCIRuntime:"runsc", CgroupParent:"/cpulimit/", CPU:1, Memory:10000}}} got: &api.ListPluginRuntimesResponse{Runtimes:[]api.PluginRuntimeDetails{api.PluginRuntimeDetails{Type:"container", Name:"gvisor", OCIRuntime:"", CgroupParent:"", CPU:1, Memory:10000}}} === RUN TestListPluginRuntimeTyped/unsupported --- FAIL: TestListPluginRuntimeTyped (0.01s) === RUN TestListPluginRuntimeUntyped/#00 sys_plugins_runtimes_test.go:197: expected: &api.ListPluginRuntimesResponse{Runtimes:[]api.PluginRuntimeDetails{api.PluginRuntimeDetails{Type:"container", Name:"gvisor", OCIRuntime:"runsc", CgroupParent:"/cpulimit/", CPU:1, Memory:10000}, api.PluginRuntimeDetails{Type:"container", Name:"foo", OCIRuntime:"otherociruntime", CgroupParent:"/memorylimit/", CPU:2, Memory:20000}, api.PluginRuntimeDetails{Type:"container", Name:"bar", OCIRuntime:"otherociruntime", CgroupParent:"/cpulimit/", CPU:3, Memory:30000}}} got: &api.ListPluginRuntimesResponse{Runtimes:[]api.PluginRuntimeDetails{api.PluginRuntimeDetails{Type:"container", Name:"gvisor", OCIRuntime:"", CgroupParent:"", CPU:1, Memory:10000}, api.PluginRuntimeDetails{Type:"container", Name:"foo", OCIRuntime:"", CgroupParent:"", CPU:2, Memory:20000}, api.PluginRuntimeDetails{Type:"container", Name:"bar", OCIRuntime:"", CgroupParent:"", CPU:3, Memory:30000}}} --- FAIL: TestListPluginRuntimeUntyped (0.01s)

After mapstructure.Decode attemps, I resorted to use json.Marshal and json.Unmarshal to put Data["runtimes"] in JSON bytes and let the library do the work, and the tests pass now. Admittedly, I feel this is a bit weird and hacky way. I'm open to any thoughts and tips that you have.

The "bug" here was that mapstructure didn't correctly guess the translation between field name and JSON key. You can give it explicit instructions in 2 ways: either create a mapstructure.DecoderConfig and set the TagName to "json" so that it uses the json tags instead of its default "mapstructure". Or you can set the mapstructure keys in the struct like so:

type PluginRuntimeDetails struct { Type string `json:"type" mapstructure:"type"` Name string `json:"name" mapstructure:"name"` OCIRuntime string `json:"oci_runtime" mapstructure:"oci_runtime"` CgroupParent string `json:"cgroup_parent" mapstructure:"cgroup_parent"` CPU int64 `json:"cpu" mapstructure:"cpu"` Memory int64 `json:"memory" mapstructure:"memory"` }

If you go with the latter method, the tests pass with this as the decoding step, which is probably my personal preference because the "interesting" code is more straightforward:

if err = mapstructure.Decode(secret.Data["runtimes"], &runtimes); err != nil { return nil, fmt.Errorf("unable to parse runtimes") }

Setting DecoderConfig looks like this:

decoderConfig := mapstructure.DecoderConfig{ TagName: "json", Result: &runtimes, } decoder, err := mapstructure.NewDecoder(&decoderConfig) if err != nil { return nil, err } if err = decoder.Decode(secret.Data["runtimes"]); err != nil { return nil, fmt.Errorf("unable to parse runtimes") }

LGTM! One potential typo and just nits otherwise
