Deploy Instructions

Setup environment

1. Install Java 11 JDK (And add an alias to your .bashrc)

alias java11='/usr/lib/jvm/jre-11/bin/java'

2. Create deployment directory /app/depl/clock-api
3. Create /app/depl/clock-api/launch.sh (Don't forget to chmod +x)

/usr/lib/jvm/jre-11/bin/java -Xms512M -Xmx1024M -Dserver.port=41566 -jar clock_api.jar

4. Run a test ./launch.sh to see if it runs
5. Create /etc/systemd/system/clock-api.service

[Unit]
Description=iOS Alarm Clock API Server

[Service]
WorkingDirectory=/app/depl/clock-api/
ExecStart=/bin/bash launch.sh
User=jvmapps
Type=simple
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

6. If you haven't set up the execution user yet:

groupadd -r appmgr
sudo useradd -r -s /bin/false -g appmgr jvmapps
id jvmapps
chown -R jvmapps:appmgr /app/depl/clock-api

7. Run deploy.sh in your local machine (Don't forget to change HOST)
8. Add aliases to your .bashrc

alias clock-restart='sctl restart clock-api'
alias clock-log-all='jctl -u clock-api --output cat'
alias clock-log='clock-log-all -f'

9. Add Nginx mapping in /etc/nginx/nginx.conf (Change the host names to your host name)

# Clock API HTTP
server
{
    listen 80;
    listen [::]:80;
    server_name alarm-clock-api.hydev.org;

    location ^~ /
    {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_pass http://alarm-clock-api.hydev.org:41566/;
        proxy_redirect off;
    }
}

10. Reload Nginx systemctl restart nginx
11. Get HTTPS certbot
12. Clean up the indentation in /etc/nginx/nginx.conf because certbot always makes a mess ;-;
    The final result should look something like:

# Clock API HTTP Redirect to HTTPS
server
{
    listen 80;
    listen [::]:80;
    server_name alarm-clock-api.hydev.org;
    return 301 https://$host$request_uri;
}

# Clock API HTTPS
server
{
    server_name alarm-clock-api.hydev.org;

    location ^~ /
    {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_pass http://alarm-clock-api.hydev.org:41566/;
        proxy_redirect off;
    }

    listen [::]:443 ssl; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/alarm-clock-api.hydev.org/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/alarm-clock-api.hydev.org/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

13. Enable auto start systemctl enable clock-api
