※I am a beginner, so if you have any information you need, please comment.
Based on the yaml file, I am trying to publish a sample app that has already been launched in Pod via Ingress.
$kubectl apply -f ./overlays/stg/bookinfo-ingress.yaml
■Errormessage
Error from server (InternalError): error when creating "./overlays/stg/bookinfo-ingress.yaml": Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": failed to call webhook: Post "https://ingress-nginx-controller-admission.ingress-nginx.svc:443/networking/v1/ingresses?timeout=10s": x509: certificate signed by unknown authority

UPGRADE FAILED: Internal error occurred: failed calling webhook "validate.nginx.ingress.kubernetes.io": Post : x509: certificate signed by unknown authority
this is the exact error which comes when I am using helm upgrade.
tried to apply the previous local values file to helm upgrade. did not work
Running the following command fixed the problem. I am unable to find the root cause of the same
kubectl delete -A ValidatingWebhookConfiguration ingress-nginx-admission
Currently, we are trying to setup neutron for our cloud server. Since everyone is new to this, we are struggling a bit. When we entered this command:
openstack network create --share --external \
--provider-physical-network provider \
--provider-network-type flat provider
And it throws this error:
Error while executing command: HttpException: 503, The Keystone service is temporarily unavailable.: 503 Service Unavailable: The server is currently unavailable. Please try again at a later time.
We are following openstack docs guide to a T.
Does anyone know what causes this error and how to fix it?
Thanks.
I fixed it, it was a problem with MariaDB. When we updated it from 10.1 to 10.3, I couldn't access my DB, so when I fixed that error it works now.
I tried to create client app of my API created using API Platform. I follow this guide https://api-platform.com/docs/client-generator/vuejs/.
I use Laravel Homestead for the VM when developing it.
I've added myapp .crt file to Keychan Access.
Problem was, when I try to execute
generate-api-platform-client --generator vue https://myapp-api.local/api src/
It return error message like this:
{
api: Api { entrypoint: 'https://myapp-api.local/api', resources: [] },

I'm thinking this is related with SSL certificate. That node doesn't recognise the certificate. How to make node.js recognise the custom SSL certificate generated by Homestead?
it failed to verify https signature.
To disable it, type in shell
export NODE_TLS_REJECT_UNAUTHORIZED=0
I try to get all Documents from Firestore using the below function.
The credentials are stored in an encrypted file in a GCP Cloud Source repository.
I decrypted the configuration in the Cloud Build trigger and set the ENV in the Dockerfile pointing to the file. I see the content by RUN ls /app/credentials.json.
The error I get in the application log:
rpc error: code = Unavailable desc = all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: authentication handshake failed: x509: certificate signed by unknown authority"

This error is the result of an HTTPS failure where the certificate cannot be verified. The Alpine base image is missing a package that provides root certificates. Currently the Cloud Run quickstart is missing this for at least the Go language.
Assuming this is your problem, add the following to the final stage of your Dockerfile:
RUN apk add --no-cache ca-certificates
I have LRP camera which produces RTSP stream in rtsp://172.16.4.6. I use VLC to see this streaming. Then I need to use ALPR Daemon for passing stream in http:// to recognize registration plates captured by camera. According to documentation in should be only http://. So using VLC I am trying to convert/transcode it to proper format. What is the problem, that I am not familiar with this field and have no time to study basic.
I installed apache2 on ubuntu that has port 80 and http://127.0.0.1 address. Then I tried to use some of approaches from documentation https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/ , then I tried $vlc -I http rtsp://172.16.4.6:554/HighResolutionVideo :sout='#transcode{vcodec=MJPG,vb=800,fps=5}:std{access=http{mime=multipart/x-mixed-repace},mux=mpjpeg,dst=127.0.0.1:80/go.mjpg,delay=0}'
But then I have this error log:

I think you have a typo in repace, Try this:
--sout #transcode{vcodec=MJPG,venc=ffmpeg{strict=1}}:standard{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:80/go.mjpg}
