gvisor is a Go library typically used in Devops, Continuous Deployment, Docker applications. gvisor has no bugs, it has a Permissive License and it has medium support. However gvisor has 3 vulnerabilities. You can download it from GitHub.

gVisor is an application kernel, written in Go, that implements a substantial portion of the Linux system surface. It includes an Open Container Initiative (OCI) runtime called runsc that provides an isolation boundary between the application and the host kernel. The runsc runtime integrates with Docker and Kubernetes, making it simple to run sandboxed containers.

            Google cloud run cannot reach Cloud SQL
            Asked 2021-Jul-02 at 10:32

            Everything was working fine just a moment ago but suddenly Google Cloud Run cannot connect with Cloud SQL. Both Cloud Run and Cloud SQL are in same project. Cloud SQL has public IP.

            Cloud Run is running a containerized Django/uwsgi/nginx application. Getting following error:

            ...

            ANSWER

            Answered 2021-Jul-02 at 09:49

            Cloud Run uses an unix socket to connect to SQL.

            From your error message, it looks like it tries to connect directly to the IP.

            I would check the application code and see if there was an undetected update, the connection string should be based on a socket and not on an IP,

            socket format is: /cloudsql/connection_id

            There's a bit to unpack here. In short, I think you might be confusing build time with runtime secrets and how they are accessed.

            If you do not need access to secrets in your compilation or test phases, you can omit the availableSecrets stanza from your cloudbuild.yaml. That pulls in secrets at build time. For example, suppose you wanted to run your tests in Cloud Build, and you needed an API key or database password to execute the tests. That's when you'd use the Cloud Build + Secret Manager integration.

            Chromium inside docker image on Google Cloud Run
            Asked 2020-Sep-12 at 16:55

            I'm trying to have a docker container running on google cloud run, which is containing a simple nodejs app and google chromium headless to create a PDF from HTML source. Unfortunately, Google Cloud Run seems to have issues with thatever solution I try.

            My Docker image(s) run perfectly locally and on other providers (i.E. Azure), but GCP just does not work.

            What I try:

            Basically building any docker image, installing node, npm, chromium, then running chromium --headless in the background. Then running the node app. The Node app is simply trying to connect to 127.0.0.1:9222 => that doesn't work on GCP, but anywhere else.

            I tried with the official node images of docker hub I tried with an alpine image I tried with a debian image All of these run fine locally, but not on google cloud run.

            Here's my latest test with a debian image:

            Google Cloud Run pubsub pull listener app fails to start

            Answered 2020-Aug-12 at 19:25

            Kolban question is very important!! With the shared code, I would like to say "No". The Cloud Run contract is clear:

            • Your service must answer to HTTP request. Out of request, you pay nothing and no CPU is dedicated to your instance (the instance is like a daemon when no request is processing)
            • Your service must be stateless (not your case here, I won't take time on this)

            If you want to pull your PubSub subscription, create an endpoint in your code with a Rest controller. While you are processing this request, run your pull mechanism and process messages.

            This endpoint can be called by Cloud Scheduler regularly to keep the process up.

            Be careful, you have a max request processing timeout at 15 minutes (today, subject to change in a near future). So, you can't run your process more than 15 minutes. Make it resilient to fail and set your scheduler to call your service every 15 minutes

            Answered 2020-Jul-04 at 19:02

            Thinking a bit longer about this, this behaviour is perfectly reasonable in the "serverless" model; resources(both CPU and memory) are throttled down to 0 when the service is not processing requests [1], which is exactly what ekg picks up.

            Why logs are printed out even outside of requests is still a bit of a mystery, though ..

            This is a community wiki answer. Feel free to edit and expand it if needed.

            Nvidia GPU is not officially supported with the docker driver for Minikube. This leaves you with two possible options:

            1. Try to use NVIDIA Container Toolkit and NVIDIA device plugin. This is a workaround way and might not be the best solution in your use case.

            2. Use the KVM2 driver or None driver. These two are officially supported and documented.

            I hope it helps.

            Can you run a sandbox container within a Cloud Run container?
            Asked 2020-Apr-28 at 17:28

            Let's say I would to let the user upload some python or bash script, execute it in the cloud run and get the result back. To do this I would create a Cloud Run service with a service account that has no permissions to access project resources. I would as well run the script within the nested container so the user cannot interfere with the server code and manipulate consecutive requests from other users.

            How would I make gvisor runsc or some other sandbox runtime available within the container running on Cloud Run?

            I found some resources mentioning using the privileged flag on the original container, but that is not possible with Cloud Run. Also, I cannot find any information on how to run rootless containers with runsc. Let me know if I am on the right track or if this is even possible with cloud run or should I use another service?

            Thank you.

            Currently Cloud Run (fully managed) itself runs on a gVisor sandbox itself, so its support for low-level Linux APIs for creating further container environments using cgroups or Linux namespace APIs are probably not going to be possible.

            However, since gVisor is technically an user-space sandboxing technology (though I'm not sure what level of privileges it requires), you might be able to run a gVisor sandbox inside gVisor, though I would not hold my hopes high as it's probably not designed for that. I'm guessing that gVisor sandbox does not provide ptrace capabilities for nested sandboxes to work, though you can probably ask this on gVisor’s own GitHub repository.

            For a use case like this, I recommend checking out Cloud Run for Anthos on GKE, it's a similar developer experience to Cloud Run, but runs your applications on GKE nodes (which are GCE VMs) which have full Linux system call suite available to them. Since Kubernetes podspec is available there, you can actually create privileged containers, and run VMs inside them etc.

            Usually containers themselves are supposed to be the sandbox, so attempting to create further sandboxes (like you asked earlier) is going to be a lot of platform-dependent work, even if you can get it running somehow.
