Welcome to episode 04! Let's take a closer look at how you configure bridge and host modes between multiple containers that need to communicate with one another. We also cover a balenaSound question and learn a neat trick for running scripts via balena SSH on localmode!

Alex walks us through new balenaBlocks and here's a fun challenge: can you make a project completely out of blocks? If you do, let us know and you might win a prize.
