+# This file excludes paths from the Docker build context.

+# By default, Docker's build context includes all files (and folders) in the

+#
+# There are multiple reasons to exclude files from the build context:
+#
+# 1. Prevent nested folders from being copied into the container (ex: exclude
+#    /assets/node_modules when copying /assets)

+# 3. Avoid sending files containing sensitive information

-- [ ] move runtime config out of compile-time config files, to move towards supporting releases
-  - [ ] probably need to use `def get_app_config` style functions instead of `@module_var` module variables, ([see this](https://stephenbussey.com/2019/01/03/understanding-compile-time-dependencies-in-elixir-a-bug-hunt.html))

-## Deploying
+## Deploying with docker
 
-I'm using a dumb & simple docker approach to deploying this now. Nothing automated, the basic steps are:
+The Dockerfile will enable building a new container. I do it all with docker compose, here's an example compose yml:
 
-1. ensure latest assets are built, digested, and committed to the repo
-
-    ```shell
-    # rebuild static assets:
-    MIX_ENV=prod mix phx.digest.clean --all
-    rm -rf ./priv/static/*
-    npm --prefix assets run build
-    MIX_ENV=prod mix phx.digest
-    # then do a new commit and push...
-    ```
-
-2. on server, build a new container, and run it
+```yaml
+version: '3.9'
+services:
+  shift73k:
+    build:
+      context: ./shift73k  # relative path from docker-compose.yml to shift73k repo
