Proxmox VE tips

Just some tips I gathered over time. All in one easily reachable place so I can share it wherever I want.

Please note that unless you see a shebang (#!/...) these code blocks are usually meant to be copy & pasted directly into the shell. Some of the steps will not work if you run part of them in a script and copy paste other ones as they rely on variables set before.
The { and } surrounding some scripts are meant to avoid poisoning your bash history with individual commands, etc. You can ignore them if you manually copy paste the individual commands.
I chose to write things "in the open" that way so there's still some control and things don't become a black box.

Docker compose as a systemd unit

Create file /etc/systemd/system/docker-compose@.service. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

I use PostgreSQL via the psql client. If you use a different client (eg. pgAdmin, etc.), I don't know how much will translate over.

One nice difference between psql and mysql (cli) is that if you press CTRL+C, it won't exit the client.

User administration

Login as superuser (via shell)

psql -U postgres

Open iTerm from finder

The code and instructions in this gist are from http://peterdowns.com/posts/open-iterm-finder-service.html. I've had to do this a few times and wanted to distill it the basics.

1. Open Automator
2. Create an Application
3. Choose Actions > Utilities > Run Applescript
4. Paste the contents of open_in_iterm.app into the window.
5. Save the script somewhere convenient
6. Find the script, then drag the script onto the Finder window while holding the command key (or in Yosemite, the command + option keys)
