TLS certificate generation

Root certificate

Generate private key:

openssl genrsa -out root-private-key.key 4096

Create certificate signing request (CSR):

openssl req -new -sha256 -key root-private-key.key -out root-csr.csr

100 years = 36500 days

Sign root certificate:

openssl x509 -req -sha256 -days 36500 -in root-csr.csr -signkey root-private-key.key -out root.crt

Server certificate

Use domain as Common Name. IP address does not work with Dart and Rustls.

openssl genrsa -out server-private-key.key 4096
openssl req -new -sha256 -key server-private-key.key -out server.csr
openssl x509 -req -in server.csr -CA ../root/root.crt -CAkey ../root/root-private-key.key -CAcreateserial -out server.crt -days 365 -sha256

Viewing certificates

openssl x509 -in server.crt -text -noout

Bot mode

RUST_LOG=debug cargo run -- test --tasks 10 --save-state --no-servers --test bot

Update app-manager submodule to latest

Building script for Multipass VM

Script which can be used when when app-manager is installed to multipass VM and source files are mounted. Replace SRC_DIR_LOCATION with the location of mouted source directory.

#!/bin/bash -eux

cd
mkdir -p backend_src
rsync -av --delete --progress --exclude="/target" /SRC_DIR_LOCATION/ ~/backend_src

cd ~/backend_src
cargo build --bin dating_app_backend --release
sudo -u app mkdir -p /app-secure-storage/app/binaries
sudo -u app mkdir -p /app-secure-storage/app/backend-working-dir
sudo systemctl stop app-backend
sudo cp target/release/dating_app_backend /app-secure-storage/app/binaries
sudo chown app:app /app-secure-storage/app/binaries/dating_app_backend
sudo systemctl restart app-backend
sudo journalctl -u app-backend.service -b -e -f
