Proposal: I would like to know which plugins I have installed with dtm and their status

[imxw]

Description

As a user, I would like to know which plugins I have installed with dtm and their status by dtm command.

Describe the Proposal

Examples are as follows

• dtm list resources gets plugins that I have installed
• dtm show states --plugin=argo gets the state of argo plugin
• dtm show states --plugin=all gets the full content of the state file

Has the Feature been Requested Before?

No

Describe the Alternatives You Have Considered

Now all installed plugins and their status are recorded in the state file, which can be read to output the list of installed plugins and their status.

Additional Context

N/A

Great idea!

Status is actually divided into two parts:

1. The states recorded in the "State Backend"(devstream.state now)
2. The real status with the resources

So maybe we need a command to get all these two "status".

---

Command Design:

• dtm show status # return all plugins' status
• dtm show status --plugin=PLUGIN_NAME # return the status with PLUGIN_NAME

The output information should cover the 2 parts status mentioned above.

If you agree with this implementation idea, I will continue to add the specific design of output information. /cc @devstream-io/devstream

The printing information design

• We need to know the Options, it tells us the configuration we used to deploy the plugin instance.
• And we need to know the Status, it should be "Recorded State" + "Resource Real State".
• If "Recorded State" == "Resource Real State", just printing one "Status".

See the details below:

1. Show the status with one plugin instance - dtm show status --plugin=demo

1.1 Drifted == true

$ dtm show status --plugin=demo
Name: demo
Plugin: githubactions-golang
Drifted: true (true if State != Resource)
Options:
    Foo: bar // The options map printed. Get from the state file.
Status:
    State:
         Foo: bar // The state map is printed.
    Resource:
         Foo: bar // The resource map is printed.

$_

1.2 Drifted == false

$ dtm show status --plugin=demo
Name: demo
Plugin: githubactions-golang
Drifted: false(true if State != Resource)
Options:
     foo: bar // The options map printed. Get from the state file.
Status:
     foo: bar // The state/resource map printed.

$_

2. Show the status with all plugins instances - dtm show status

$ dtm show status

----------------------- 1/2 -----------------------

Name: demo1
Plugin: githubactions-golang
Drifted: true (true if State != Resource)
Options:
    Foo: bar // The options map printed. Get from the state file.
Status:
    State:
         Foo: bar // The state map is printed.
    Resource:
         Foo: bar // The resource map is printed.

----------------------- 2/2 -----------------------

Name: demo2
Plugin: githubactions-golang
Drifted: false (true if State != Resource)
Options:
     Foo: bar // The options map printed. Get from the state file.
Status:
     Foo: bar // The state map is printed.

$_

Great. Let's continue with this design.
