Pi-Cluster | How to set up a Raspberry Pi Spark Cluster on Arch

kandi X-RAY | Pi-Cluster Summary
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.

QUESTION
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:
...ANSWER
Answered 2022-Feb-15 at 15:38You 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:

I am trying to translate a manually created service to a cloudformation template but I keep getting errors.

I am using terraform to create an ECS cluster in AWS.
...ANSWER
Answered 2021-Sep-08 at 06:13It turns out this is caused by needing the ecs:DescribeClusters Action to be allowed on the user executing terraform apply.
Thanks to @ydaetskocR for pointing me in the right direction.
QUESTION
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:
...ANSWER
Answered 2021-Jul-29 at 21:55The 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.
QUESTION
I know this comes up often, but I've tried the usual remedies:
"homepage": "/admin/v2"in thepackage.jsonin theindex.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-Mar-09 at 21:59Ok, figured it out... the problem was in the nginx.conf:

So this is what I'd like to do because my /admin/v2 route continues to work properly... however, the static assets cannot be found for the legacy (<= 2013) PHP application at the /admin route:

QUESTION
The documentation is a bit confusing there are two sets:
- https://docs.microsoft.com/en-us/azure/key-vault/general/key-vault-integrate-kubernetes
- https://azure.github.io/secrets-store-csi-driver-provider-azure/configurations/identity-access-modes/pod-identity-mode/
At any rate, I'm able to do the following to see that secrets are in the Pod:
...ANSWER
Answered 2021-Feb-22 at 16:11The 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.
QUESTION
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:

Answered 2020-Oct-06 at 17:13Actually, came across this answer which was pretty much the exact issue I was experiencing:
React & nginx routing to subdirectory
So my final ./nginx/default.conf looked like this:
QUESTION
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 4000:4000skaffold dev --port-forwarddocker run -p 4000:4000
However, when I try to connect to access it through browser via the minikube ip, 192.168.64.5/admin 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:
...ANSWER
Answered 2020-Oct-02 at 18:23Managed 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.
QUESTION
Figured this would be straight forward, but apparently this is not the case.
I have two CRA microservices running at:
//admin
minikube ip is 192.168.64.5, so the full routes should be 192.168.64.5/ and 192.168.64.5/admin 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:
ANSWER
Answered 2020-Sep-30 at 21:37Ok, 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.
The final ingress.yaml I have is:

Install Pi-Cluster
You can use Pi-Cluster like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
