Docker for Mac Setup/Notes

Notes

making notes as I transition from DockerMachine/VBox to Docker for Mac https://blog.bennycornelissen.nl/docker-for-mac-neat-fast-and-flawed/

Fundamental Dev Env Questions

1. Should DBs live inside D4M and use bind mount for Data (this makes setup for others MUCH easier) -OR- Use Host DBs
2. Where should code live and how to inject source dir into Compose. Could use a single env var that is customizable. i.e. export D4M_DEV_SOURCE="/Users/hbeaver/code"

Kernel

kernel running on D4M is Moby, not the distro you have in your image.

Connecting to Host Net

sudo ifconfig lo0 alias 172.16.1.1

Shelling into Docker for Mac

Granting access to PG from D4M

Add the following to your pg_hba.conf file.

 host    all             all             172.16.1.1/24        trust

Restart PG brew services restart postgresql

Alternately - running PG in Docker

Using Docker for Mac PG can easily write to OSX disk. Previously, this was a major pain in the ass.
