I am fairly new to the Google Cloud platform and Docker and set-up a cluster of nodes, made a Dockerfile that copies a repo and runs a Clojure REPL on a public port. I can connect to it from my IDE and play around with my code, awesome!

That REPL should however probably tunneled through SSH, but here is where my problem starts. __I can&#39;t find a suitable place to SSH into__ for making changes to the repo that Docker runs the REPL on:

  - The exposed IP just exposes the REPL service (correct kubernetes term?) and does not allow me to SSH in. 
  - Neither does the cluster master endpoint, it gives me a public key error even though I&#39;ve followed the `Adding or removing SSH keys for all of the instances in your project` part [here](https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys).

I would like to edit the source files via SSH but I would need to access the docker code repo. I don&#39;t know how to proceed.

I understand this isn&#39;t exactly a typical way to deploy applications so I am not even sure it&#39;s possible to have multiple nodes work with a modified docker codebase (do the nodes share the JVM somehow?).

Concretely my question is how do I SSH into the docker container to access the codebase?

I&#39;ve been using both for my startup and to me, the functionality is the same. Until now, the instances I&#39;ve been creating  are only for computation. I&#39;m wondering how GCE disk images and snapshots are different in terms of technology, and in which situation it is better to use one over the other.

I have recently performed a migration to Google Cloud Platform, and I really like it.

However I can&#39;t find a way to monitor the memory usage of the Dataproc VM intances. As you can see on the attachment, the console provides utilization info about CPU, disk and network, but not about memory.

Without knowing how much memory is being used, how is it possible to understand if there is a need of extra memory?

I have 2 Google Compute Engine instances and I want to open port 9090 in both the instances. I think we need to add some firewall rules.   

Can you tell me how can I do that?

The root disk size in GCE is 10 gigs. How do I increase this? I cant find the option in the console or the gcutil flags. This can be easily done in AWS.

I was wondering what the difference between App Engine &amp; Compute Engine are. Can anyone explain the difference to me?

**SITUATION:**

I follow this tutorial: https://cloud.google.com/nodejs/tutorials/bookshelf-on-compute-engine

Everything works fine until I do `npm start` and go to:

http://localhost:8080

I am met with the following text on the blank page:

    Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information.

Which makes no sense since I am using OAuth. I followed the link and read the page, but I have no `GOOGLE-APPLICATION-CREDENTIALS` field anywhere, and nothing about it in the tutorial.

-------

**QUESTION:**

Could you please reproduce the steps and tell me if you get the same result ?

(takes 5 minutes)

If not, what could I have done wrong ?

I would like to transfer ownership of Google Cloud project completely. By completely I mean rather than sharing ownership between multiple users, removing my account from project. Is there any way to do it?

I wanted to know what is the difference between a Replication Controller and a Deployment within Kubernetes (1.2). Going through the getting started document (http://kubernetes.io/docs/hellonode/) I have created a deployment - but it doesn&#39;t show up on the web UI.

When I create apps from the web UI - they are created as replication controllers. Functionally though, they seem very similar (they both manage pods and have services).

So - what is the difference and when should I use each?

I&#39;ve increased for my quota of NVIDIA K80, and received the request approval. Why am I still not able to use a VM with GPUs?

Error as shown in title.

I&#39;m trying to connect to my Debian Google Compute Engine server through PuTTy (I&#39;ve tried other alternatives too) but when I do I get the error &quot;Disconnected: No supported authentication methods available (server sent: publickey)

![](https://puu.sh/5x8OY/ec3a73a225.png)

The google server came without a username and password, only a url to automatically login to their own terminal.

I created a new instance via the Google Cloud web console from a CentOS 6.x image. I saw a blank on the creation form where I could paste in an existing SSH key; since this was my first instance, I didn&#39;t have one yet. I assumed it would take me through the key creation process like Amazon EC2 does. It didn&#39;t.

The instance appears to be created, but I can&#39;t figure out how to get the SSH key for it. The instance web page has a button that says &quot;SSH&quot; and it let me log in briefly via a pop-up web browser window that simulates an SSH session. However, it only let me into a user-level account, not `root`. The pop-up had a menu item to change the user and changing it to `root` does nothing but generate connection errors.  Now I can&#39;t log into my instance at all!

I&#39;ve searched but can&#39;t find any straight-forward documentation that explains this aspect of Google Compute instances.

Do I have to create my own SSH keys manually and paste them into the form during instance creation?  Is there an obvious step I&#39;m missing?

I have created a new configuration profile using command: 

    gcloud init 

and now I don&#39;t know how to switch to old configuration profile without override it. 

Using `gcloud config` I can&#39;t switch to another configuration only set a property of the current configuration. 

any idea?
