How to run this as a systemd deamon

The files in this directory assume that you install the Golang version of ClusterCockpit to /var/clustercockpit. If you do not like that, you can choose any other location, but make sure to replace all paths that begin with /var/clustercockpit in the clustercockpit.service file!

If you have not installed yarn and go already, do that (Golang is available in most package managers).

The config.json can have the optional fields user and group. If provided, the application will call setuid and setgid after having read the config file and having bound to a TCP port (so that it can take a privileged port), but before it starts accepting any connections. This is good for security, but means that the directories frontend/public, var/ and templates/ must be readable by that user and var/ writable as well (All paths relative to the repos root). The .env and config.json files might contain secrets and should not be readable by that user. If those files are changed, the server has to be restarted.

# 1.: Clone this repository to /var/clustercockpit
git clone git@github.com:ClusterCockpit/cc-backend.git /var/clustercockpit

# 2.: Install all dependencies and build everything
cd /var/clustercockpit
go get && go build && (cd ./frontend && yarn install && yarn build)

# 3.: Modify the `./config.json` file from the directory which contains this README.md to your liking and put it in the repo root
cp ./utils/systemd/config.json ./config.json
vim ./config.json # do your thing...

# 4.: Add the systemd service unit file
sudo ln -s /var/clustercockpit/utils/systemd/clustercockpit.service /etc/systemd/system/clustercockpit.service

# 5.: Enable and start the server
sudo systemctl enable clustercockpit.service # optional (if done, (re-)starts automatically)
sudo systemctl start clustercockpit.service

# Check whats going on:
sudo journalctl -u clustercockpit.service
