You&#39;re looking for the `--quiet` flag, available across all `gcloud` commands:

    $ gcloud --help
         --quiet, -q
        Disable all interactive prompts when running gcloud commands. If input
        is required, defaults will be used, or an error will be raised.

        $ gcloud app deploy --quiet
Or also:

        $ gcloud app deploy -q

Let&#39;s say that I have the following protocol:

    protocol Identifiable {
        var id: Int {get}
        var name: String {get}
    }

And that I have the following structs:

    struct A: Identifiable {
        var id: Int
        var name: String
    }
    
    struct B: Identifiable {
        var id: Int
        var name: String
    }

As you can see, I had to &#39;conform&#39; to the Identifiable protocol in struct A and struct B. But imagine if I had N more structs that needs to conform to this protocol... I don&#39;t want to &#39;copy/paste&#39; the conformance (var id: Int, var name: String)

So I create a **protocol extension**:

    extension Identifiable {
        var id: Int {
            return 0
        }
        
        var name: String {
            return &quot;default&quot;
        }
    }

With this extension now I can create a struct that conforms to the Identifiable protocol without having to implement both properties:

    struct C: Identifiable {
    
    }

Now the problem is that I can&#39;t set a value to the id property or the name property:

    var c: C = C()
    c.id = 12 // Cannot assign to property: &#39;id&#39; is a get-only property

This happens because in the Identifiable protocol, id and name are only gettable. Now if I change the id and name properties to **{get set}** I get the following error:

*Type &#39;C&#39; does not conform to protocol &#39;Identifiable&#39;*

This error happens because I haven&#39;t implemented a setter in the protocol extension... So I change the protocol extension:

    extension Identifiable {
        var id: Int {
            get {
                return 0
            }
            
            set {
                
            }
        }
        
        var name: String {
            get {
                return &quot;default&quot;
            }
            
            set {
                
            }
        }
    }

Now the error goes away but if I set a new value to id or name, it gets the default value (getter). Of course, **the setter is empty**.

My question is:
**What piece of code do I have to put inside the setter?** Because if I add *self.id = newValue* it crashes (recursive).

Thanks in advance.

Is it possible to do silent deployment when using `gcloud app deploy`

When I run the command `gcloud app deploy ./deployment/app.yaml --version v1` its always prompting for 

`Do you want to continue (Y/n)?  Y`

how to automate this? 
is there any flag that we can pass in to mute this?

I&#39;m playing with Google container engine on gcloud. So after successfully finished `gloud init` I followed instructions and did:

    gcloud container clusters get-credentials cluster-1 --zone europe-west1-c --project whatever

And then:

    kubectl proxy

But I got the following error message:

    error: google: could not find default credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

I do see stuff in `~/.kube/config` file so I&#39;m not sure what went wrong. I have `minikube` also installed on the machine but I don&#39;t think that&#39;s a problem.

Install Google Cloud components error from gcloud command

How can I change the current running project to another project in GCP (*Google Cloud Platform*) account using **cli commands** other than using **`gcloud init`** manually?

 **`gcloud projects list`** will list the projects running on my account. I want to change the current project to any other project from the list using a cli command. 

How to change the project in GCP using CLI commands

In the google cloud gui console I went to &quot;IAM &amp; admin&quot; &gt; &quot;Service accounts&quot; and created a service account named &quot;my-service-account&quot; with the viewer role.

I then ran this command:

    gcloud iam service-accounts get-iam-policy my-service-account@mydomain.iam.gserviceaccount.com

and saw this output:

    etag: ACAB

According to the docs this means this service account has no policy associated with it. So I assigned it a &quot;role&quot; which is not included in its &quot;policy&quot;.

How do I list the roles associated with a service account?

EDIT:
Thanks to the excellent answer to this question I can now loop over all projects and get what I want. so, depending on your version of these cmd tools, this should list all role bindings of a single service account across all projects:

    gcloud projects list | \
      awk &#39;{print $1}&#39; | \
      xargs -I % sh -c &quot;echo &quot;&quot;; echo project:% &amp;&amp; \
      gcloud projects get-iam-policy % \
      --flatten=&#39;bindings[].members&#39; \
      --format=&#39;table(bindings.role)&#39; \
      --filter=&#39;bindings.members:YOU-SERVICE-ACCOUNT@blah.com&#39; \
      ;&quot; 

How do I list the roles associated with a gcp service account?

I am trying to create an internal app to upload files to google cloud. I don&#39;t want each individual user or this app to log in so I&#39;m using a service account. I login into the service account and everything is ok, but when I try to upload it gives me this error:
ServiceException: 401 Anonymous caller does not have storage.objects.list access to bucket

[![This is the error that I get][1]][1]

As you can see I am logged in with a service account and my account and(neither service or personal) works
