kandi X-RAY | Pi-Cluster Summary

Pi-Cluster is a Python library typically used in Manufacturing, Utilities, Construction, Internet of Things (IoT), Raspberry Pi, Spark applications. Pi-Cluster has no bugs, it has no vulnerabilities and it has low support. However Pi-Cluster build file is not available. You can download it from GitHub.

This repo is being used to document my project for building a small raspberry pi cluster running spark. Similar to this article which I used as a guide, I only wanted to have to use a single wall plug for the entire setup. I also wanted to minimize the footprint of the cluster. In this example all of the devices except for the USB hub are powered by USB. I have broken the project into 3 sections: building the cluster, setting up the os, and configuring spark.

            ECS task unable to pull secrets or registry auth
            Asked 2022-Feb-15 at 15:38

            I have a CDK project that creates a CodePipeline which deploys an application on ECS. I had it all previously working, but the VPC was using a NAT gateway, which ended up being too expensive. So now I am trying to recreate the project without requiring a NAT gateway. I am almost there, but I have now run into issues when the ECS service is trying to start tasks. All tasks fail to start with the following error:



            Answered 2022-Feb-15 at 15:38

            You need to create an interface endpoints for Secrets Manager, ECR (two types of endpoints), CloudWatch, as well as a gateway endpoint for S3.

            Refer to the documentation on the topic.

            Here's an example in Python, it'd work the same in TS:

            Terraform erroring waiting for ECS cluster
            Asked 2021-Sep-08 at 06:13

            I am using terraform to create an ECS cluster in AWS.



            Answered 2021-Sep-08 at 06:13

            It turns out this is caused by needing the ecs:DescribeClusters Action to be allowed on the user executing terraform apply.

            Clarification on the security of using secretKeyRef in Kubernetes manifest

            I was looking into an entirely separate issue and then came across this question which raised some concerns:


            I'm doing something pretty similar. I'm using the CSI Driver for Azure to integrate Azure Kubernetes Service with Azure Key Vault. My manifests for the integration are something like:



            Answered 2021-Jul-29 at 21:55

            The comment on the answer you linked was incorrect. I've left a note to explain the confusion. What you have is fine, if possibly over-built :) You're not actually gaining any security vs. just using Kubernetes Secrets directly but if you prefer the workflow around AKV then this looks fine. You might want to look at externalsecrets rather than this weird side feature of the CSI stuff? The CSI driver is more for exposing stuff as files rather than external->Secret->envvar.

            Assets being served in development, but not production and getting "Uncaught SyntaxError: Unexpected token '<'"
            Asked 2021-Mar-09 at 21:59

            I know this comes up often, but I've tried the usual remedies:

            • "homepage": "/admin/v2" in the package.json
            • in the index.html

            These things work for my development environment, but not for production. I'm pretty sure the issue is in my nginx.conf for the microservice, that sits behind the ingress-nginx controller.

            It is:

            Answered 2021-Feb-22 at 16:11

            The CSI secret store driver is a container storage interface driver - it can only mount to files.

            For postgres specifically, you can use docker secrets environment variables to point to the path you're mounting the secret in and it will read it from the file instead. This works via appending _FILE to the variable name.

            Per that document: Currently, this is only supported for POSTGRES_INITDB_ARGS, POSTGRES_PASSWORD, POSTGRES_USER, and POSTGRES_DB.

            nginx-ingress sending traffic to nginx in pod but not returning assets
            Asked 2020-Oct-06 at 17:13

            Basically, I'm having difficulty getting nginx to serve the npm build from a CRA web app that is at the subpath /new-admin.

            I do have in the package.json "homepage": "/new-admin" and in the index.js. Works fine in development, but now that I'm trying to make a staging/production copy it isn't and I'm pretty sure it is due to the ./nginx/default.conf. Of the various configurations I've tried, none have worked and I either get:

            • 500 Internal Server Error

            This is what I have:

            nginx not serving JS, CSS files for PHP app behind ingress-nginx
            Asked 2020-Oct-02 at 18:23

            Can't seem to get this working and need help on where I am going wrong.

            Have an old PHP app subpathed at /admin. ingress-nginx forwards the traffic for it to an nginx server running in the Pod. I've verified I can do the following and it serves the assets correctly:

            • kubectl port-forward 4000:4000
            • skaffold dev --port-forward
            • docker run -p 4000:4000

            However, when I try to connect to access it through browser via the minikube ip, for example, I just get the following:

            It displays the HTML, but none of the assets are loading because they aren't being found and I'm not sure why.

            This is the nginx default.conf that serves the PHP application. I'd like to fix it in here, if possible, as opposed to in the ingress.yaml because they tends to mess with my other routes and took me a bit of time to get those working properly.

            Here is what I have for those files:

            Managed to get all routes working by moving this path to a separate ingress config. Probably not ideal, but I just need it working until it is replaced in hopefully 6 months.

            How do you get subpaths to work for create-react-app in minikube?
            Asked 2020-Sep-30 at 21:37

            Figured this would be straight forward, but apparently this is not the case.

            I have two CRA microservices running at:

            • /
            • /admin

            minikube ip is, so the full routes should be and in browser. The Dockerfile.dev just has each being started with npm start.

            The root route works fine, but the /admin I can't get the static files to serve correctly for the life of me... spent several hours on it. All I get back is Uncaught SyntaxError: Unexpected token '<', which stems from the static files not being served correctly.

            That being said, when I do npm build, or just go to localhost:3000/admin, the web application is served correctly. npm build is obviously not ideal for development. Using localhost just circumvents the cluster routing, so issues that could have been caught in dev, will now show-up in staging. I'll have to go that route if I can't get this working though.

            I've tried the "homepage:" and basename={process.env.PUBLIC_URL}, but it is not resolving the issue:

            Ok, apparently the issue was nginx.ingress.kubernetes.io/rewrite-target: /$1 in the ingress.yaml. I commented it out and it started working.

            You can refer to the index.html, index.js, and package.json above as those are unchanged.
