BlazorPong Project for one of my University Exams + Thesis

No javascript allowed(except for the JSInterop to listen to an event not supported by blazor or to log in browser console).

Trying Blazor for the first time, please be patient. Devops integrated, deployed as self-contained, 32 bit because i chose the free tier plan. Using SignalR Core

DockerCompose

cd BlazorPong

docker-compose -f "Docker-Compose.yml" up -d --build

docker-compose -f "Docker-Compose.yml" down --remove-orphans

PROD DEPLOY docker context create remote --docker "host=ssh://root@HOST" CD source\repos\MACEL94\BlazorPong\BlazorPongWasm docker-compose -c remote -f Docker-Compose.PROD.yml up

If you get paramiko.ssh_exception.PasswordRequiredException: private key file is encrypted and you can't use ssh-agent on windows: ssh-agent -s --> unable to start ssh-agent service, error :1058

Check for OpenSSH Authentication Agent service, mine was disabled.

It also needs to be updated so you can ssh-add correctly: PowerShell/Win32-OpenSSH#1263 (comment)

...still no luck. i ended up using scp scp .\Docker-Compose.PROD.yml root@host:app

Then ssh on machine as root cd app docker-compose -f "Docker-Compose.PROD.yml" down --remove-orphans docker-compose -f "Docker-Compose.PROD.yml" up -d --build

sudo certbot certonly --webroot -w /root/certs-data/ -d dockerblazorpongwasm.cloud -d www.dockerblazorpongwasm.cloud

Save certificates to localhost scp -r user@your.server.example.com:/path/to/foo /home/user/Desktop/

To generate localhost SSL Use this Dockerfile

# we use the tiny alpine linux as base
FROM alpine

# install openssl
RUN apk update && \
  apk add --no-cache openssl && \
  rm -rf "/var/cache/apk/*"

# create and set mount volume
WORKDIR /openssl-certs
VOLUME  /openssl-certs

ENTRYPOINT ["openssl"]

to use it

docker build -t my-openssl:latest .

docker run -it --rm -v "C:/some/path:/openssl-certs" my-openssl
req -newkey rsa:2048 -keyout privkey.pem -x509 -days 365 -out fullchain.pem

req -x509 -nodes -new -sha256 -days 1024 -newkey rsa:2048 -keyout privkey.pem -out fullchain.pem
