pre-flight | core dependencies are up to date before npm start | Datepicker library

I am trying to create cluster by using this article in my WSl Ubuntu. But It returns some errors.

Errors:

I can configure apiserver.service-node-port-range extra-config with a port range like 10000-19000 but when I specify a comma separated list of ports like 17080,13306 minkube wouldn't start it will bootloop with below error

I'm having an error trying to have docker set iptables false when minikube start fails.

Below are my logs:

I am trying to setup a varnish cache where the varnish instance is hosted on one server and the backend is on a different server. They are both on aws lightsail instances. The issue I am having is when I try and go to the site, I get the Error 503 Backend fetch failed error. Here is the varnish default.vcl:

I've set up a POST endpoint in apim and I can test that it's working fine when bypassing the apim - however when I call it from my site I'm getting a 200 empty response along with Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://apim.azure-api.net/project. (Reason: CORS header “Access-Control-Allow-Origin” missing)

I believe it's happening because "When OPTIONS request is processed as a pre-flight request and doesn't match CORS policy settings: immediately terminate the request with an empty 200 OK response" - which based on the docs here: https://docs.microsoft.com/en-us/azure/api-management/api-management-cross-domain-policies the attribute terminate-unmatched-request is defaulted to true - when I try to set this in the policies to false it is not getting saved, for example:

Im currently setting up a new MongoDB ops manager machine. Installation works fine but I can't start the mongodb-mms service. The starting of Instance 0 fails with an java.lang.OutOfMemoryError exception. I use the same configuration as on my test server (2 CPU cores, 8gb ram), there the service starts without any interrupt. Changing the ulimit configuration / starting the service with root user has no effect.

New Server specs:

• 10 Vcores at 2.0Ghz
• 48gb Ram
• 800gb storage
• Ubuntu 18.04 LTS 64bit

Since the new server is shared with others is it possible that the host limited the cpu usage per user?

mms0.log:

I have set up three services in Docker Compose: A frontend (built with Angular 11), a backend and a dataservice (both built with Typescript/Express). The frontend sends requests to the backend, which in turn calls the data service to answer the request. This works when I run it on localhost, and it works when I execute the API calls with curl from within the containers. But when I try to run this in Docker and access the frontend with Firefox or Chrome, I receive an error message: Either ERR_NAME_NOT_RESOLVED (Chrome) or CORS request did not succeed (Firefox).

I cannot figure out why this happens. Something connected to pre-flight CORS requests made by Angular? How can I make this work?

The issue in more detail:

I'm facing an issue with kubectl server version.

So, when I try to join a new node I get this:

Thanks for your help

I'm currently trying to perform the first deploy of my app with Dokku. Unfortunately, I have an error:
