Server updater is a simple golang program for updating ubuntu servers. We had the problem that our monitoring system is just for our applications running in kubernetes. But we didn't want to escape a container to upgrade the server and we also didn't want to create a bash script where we wouldn't be notified of failures. So we created this program it wil run apt{update,upgrade,autoremove} and then notify failure or success with a Discord webhook.
docker build -f test.Dockerfile .The binary can be downloaded from the github release page.
When executed it need the two webhook endpoints {WEBHOOK_URL_ERROR, WEBHOOK_URL_INFO} these can ether be set as env variables or you can pass an env file with the flag --env-file. Because the application does a server update it needs to be run as root.
You can ether download the binary and create a cron job yourself or use the install script below.
⚠DANGER⚠: this install script will override your existing crontabs for root
The install script will download the binary to /usr/local/bin/server-updater and create a root only config file at /etc/server-updater/server-updater.env. Then it will create a crontab that will run at 2am every day and pipe the log output to /tmp/server-updater
curl -fsSL https://raw.githubusercontent.com/0xFEEDC0DE-dev/server-updater/master/install.sh | sh
# Set the webhooks in the config file
sudo vim /etc/server-updater/server-updater.env
# enable the cron service so that the crontab from the install script is run
sudo systemctl enable cron
