Dear Reader,

I use Lando a lot these days. I’ve got .lando.yaml files scattered all over my file structure. I love it because it takes the yak shaving out of development. One thing that bothers me though is the fact that every time I spin up a new lando instance and it has a database, it gets a new port number. I have to go find that port number so I can open my SQL editor to tinker. So over the past year I’ve been writing this little script. It’s finally to the point where I think it might be useful to others so I’m sharing it. Also, if I ever lose it, I’ve now got it backed up on my blog. :)

This is a snippet form my .bash_macros file. It creates the command db. Now all I need to do when I need to find the port for the database is type db and it shows me all the running db instances and their exported port numbers.

This was written in bash. I use it on Windows WSL running ubuntu but it should run on any standard Linux. Not sure about OSX.

This is one of those “this works for me so I’m sharing in case it works for you too” pieces of code. I didn’t setup a repo for it because I’m not interested in changes. If you do improve it, you blog about it and then we’ll all be the wiser.

Until next time,
